Introduction: The prevalence of psychiatric disorders among prisoners remains a major public health issue worldwide. In France, despite the increasing number of persons who are incarcerated (+30% between 1992 and 2002 with a 120% prison overcrowding), and a historical concern about the mental health of persons in detention and its management, no systematic review has been published on this subject. The aim of this article is to present the results of a systematic review of the literature on the prevalence of psychiatric disorders in French prisons., Method: The reporting of this systematic review conforms to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) checklist. We searched the PubMed and Web of Science databases. We used combinations of keywords relating to prison (prison*, jail*, inmate*), to psychiatry ("mental health", psychiatr*), and to France (France, French). This work was completed with a search through the digital libraries of the École des Hautes Études en Santé Publique (EHESP) and of the Système Universitaire de Documentation (Sudoc) to obtain data from academic works and the gray literature. References cited in studies included in this review were also examined. All references published up to September 2022, written in English or French, presenting the results of original quantitative studies on the prevalence of psychiatric disorders in correctional settings were included. Two researchers independently extracted data from included references according to a pre-established protocol., Results: Among 501 records identified, a total of 35 papers based on 24 epidemiological studies met the eligibility criteria for inclusion in this review: 16 were cross-sectional, 7 retrospective and 1 both cross-sectional and retrospective. All papers were published between 1999 and 2022. We found one European study, 5 international studies, 18 regional or local studies. Of these, 21 studies had all-male or mixed gender samples (but when the sample was mixed gender, it was always at least 92% male). Almost half of the studies (n=11) involved a small sample of fewer than 500 persons. Half of the studies involved a sample of recently incarcerated persons: 6 involved a random sample of persons in detention, and 1 involved a sample of people incarcerated for more than 5 years. The last 5 studies focused on persons aged over 50 years and incarcerated for more than one year (n=1), incarcerated for sexual offences (n=2), placed in disciplinary cells (n=1) or in a special wing for radicalized or suspected radicalized individuals (n=1). Nine studies used standardized and validated diagnostic tools. According to the 4 studies involving representative samples and using standardized and validated diagnostic tools, the prevalence of the following psychiatric disorders was: 29.4-44.4% for anxiety disorders, 5-14.2% for PTSD, 28-31.2% for mood disorders, 6.9-17% for psychotic disorders, 32% for personality disorders and 11% for ADHD., Conclusion: This systematic review of the literature highlights the high prevalence of psychiatric disorders in French prisons. The data collected are in line with international studies. The great methodological heterogeneity of the papers included in this review calls for further rigorous research to better understand the rates of mental disorders in French prisons and to explore their determinants., (Copyright © 2024 L'Encéphale, Paris.

Background: Current scientific literature supports classical psychedelic efficacy in many psychiatric disorders. However, less attention has been given to the neurological effects of these substances. The aim of this medical thesis was to conduct a systematic review examining the neuroimaging correlates of the effects of psychedelics., Method: We performed an electronic research through Medline and Science Direct databases. A comprehensive search yielded 460 articles published up to May 2022. After a cautious screening process, we selected 49 scientific papers for further analysis., Results: Major findings included reduced functional network integration, increased between-network functional connectivity, and expansion of functional connectivity patterns repertoire under psychedelics. Thalamic gating and emotional processing were also impaired. These results positively correlated with symptom improvement in pathological populations., Conclusion: To this day, our knowledge concerning psychedelic effects remains partial. Several neurocognitive theories have been developed in recent years to model psychedelic phenomenology, but no unifying theory has emerged. Studies involving larger populations investigating various psychiatric disorders, including several neuroimaging modalities and considering medium- and long-term effects, would be necessary to deepen current knowledge., (Copyright © 2024 L'Encéphale, Paris.

Introduction: In the absence of appropriate care, psychotraumatic consequences (revival, hyperarousal, avoidance strategies, dissociation and other clinical forms of post traumatic symptoms) can take control of a large part of the subject's existence (psychological, physical, social) and affect the ability of the victim to regain ground on the intrusions that harass, and to take up new life projects. More objective than the current semiological and psychometric approaches, and in the absence of biomarkers that may be used in clinical practice, psycholinguistics opens up an epistemological renewal of the conception of trauma and its clinical consequences, in particular through the definition of the Psycho Linguistic Traumatic Syndrome (SPLIT). If such conceptions have been developed based on the analysis of traumatic accounts of subjects injured in war and attacks, other forms of psychotraumatic confrontations also deserve to be considered. In this paper, our objective was to better characterize the pronominal forms of agency in the traumatic and non-traumatic narratives produced by women victims of domestic and/or sexual violence., Methods: Nineteen women aged 20 to 60 victims of domestic violence and diagnosed with post-traumatic stress disorder (Mini International Neuropsychiatric Interview) as well as a matched control group participated in the study. The subjects completed the French versions of Post Traumatic Checklist (PCL-5), Dissociative Experience Scale (DES) and Hospital and Anxiety Depression Scale (HAD). Traumatic and non-traumatic narratives were linguistically coded and scored on the SPLIT-10 scale., Results: Traumatic narratives contained significantly more first person singular pronouns than the non-traumatic narratives of controls or the non-traumatic narratives of psychically injured people. Traumatic narratives contained significantly more of the direct object pronoun "me" as well as indirect object pronouns. In traumatic narratives, the frequency of use of the subject pronoun "I" tended to correlate negatively with the HAD-A, HAD-D and SPLIT-10, while the frequency of use of the direct object pronoun "me" tended to correlate positively with DES, HAD-A, HAD-D as well as SPLIT-10. Finally, traumatic narratives contained significantly more verbs in the passive voice than non-traumatic narratives., Discussion: There was a gradient in the use of the first person singular pronoun that was inversely correlated to the degree of traumatic valence of the narratives: the control group used "I" less often than the psychically injured people who appeared to use this pronoun all the more as their narratives had a traumatic valence. In other words, even in the so-called "non-traumatic" narratives produced by subjects suffering from post-traumatic stress disorder, the trauma seemed to be inscribed in the discourse, testimony to dissociation, as the seen in the correlation of this pronominal expression dimension of "I" with the SPLIT-10 scale. The use of the direct object complement was correlated with greater psycho-traumatic morbidity (dissociative, depressive and anxious) than the use of the "I", the latter remaining however a pathological mark instead of the use of the pronouns "we" or "one". Saying "I" translated less symptomatology than saying "me", but it was when the subject said "we" or "one" that he appeared to have returned to a normal discourse, no longer suffering from the torments of reliving or pathological dissociation. The identification of linguistic markers deserves to be pursued in order to better objectively describe post-traumatic psychiatric disorders, to better identify them in clinical practice in the field and to monitor the efficiency of the recommended psychotherapies. More generally, we may put forward the hypothesis that the direct modification of the patient's language, thanks to the intervention of the practitioner, from a speech composed of linguistic markers testifying to the trauma towards a normalized speech could help to treat post-traumatic symptoms., (Copyright © 2022 L'Encéphale, Paris.

Perinatal psychopharmacology is an emerging specialty that is gradually developing alongside perinatal psychiatry. The management of psychiatric disorders during the perinatal period is a challenge for perinatal practitioners due to the multiple changes occurring during this crucial period. This little-known specialty still suffers from inappropriate considerations on the impact of psychotropic treatments on the mother and the infant during pregnancy and postpartum, which can promote a deficiency in perinatal psychic care. However, the risks associated with insufficient management of mental health are major, impacting both the mental and physical health of the mother and the infant. In this paper, we propose a perinatal psychopharmacology prescription guide based on available scientific evidence and international and national recommendations. We thus propose a decision-making process formalized on simple heuristics in order to help the clinician to prescribe psychotropic drugs during the perinatal period., (Copyright © 2022 L'Encéphale, Paris.

The idea of applying various forms of physical activity for the betterment of physical health and the reduction of chronic medical conditions is ubiquitous. Despite evidence of successful applications of physical activity for improvement of mental health dating back to antiquity, it has until recent years remained unconventional to consider exercise as an intervention strategy for various mental health conditions. The past two decades, however, have seen a relative explosion of interest in understanding and applying various programs and forms of exercise to improve mental health. Here, our purpose is to provide a comprehensive and updated overview of the application of exercise as a strategy for improving mental health. In the present paper we first summarize contemporary research regarding short- and long-term impacts of exercise on mental health. Then an overview of the putative mechanisms and neurobiological bases underpinning the beneficial effects of exercise is provided. Finally, we suggest directions for future research as well as a series of concrete recommendations for clinicians who wish to prescribe physical activity as part of patient mental health management., (Copyright © 2023 L'Encéphale, Paris.

Obsessive-Compulsive Disorder (OCD), characterized by the combination of obsession and compulsion, is a clinical and therapeutic challenge. Many patients with OCD do not respond to first-line treatments such as serotonin selective reuptake inhibitors (SSRIs) and exposure and response prevention psychotherapy (ERP). For these resistant patients, some preliminary studies have shown that ketamine, a non-selective glutamatergic NMDA receptors antagonist, could improve the obsessive symptoms. A number of these studies have also suggested that the combination of ketamine with ERP psychotherapy may jointly potentiate the effectiveness of ketamine and ERP. In this paper, we present the existing data on the combined use of ketamine with ERP psychotherapy for OCD. We suggest that modulation of NMDA receptor activity and glutamatergic signaling by ketamine may promote the therapeutic mechanisms involved in ERP such as fear extinction and brain plasticity mechanisms. Finally, we propose a ketamine-augmented ERP psychotherapy (KAP-ERP) protocol in OCD, and we present the limitations associated with its application in clinical practice., (Copyright © 2022 L'Encéphale, Paris.

Objectives: The behavioral summarized evaluation scales, the BSE and its revised version the BSE-R, were developed and validated in the 1980-1990s. The BSE-R is still used daily by clinical teams in France and foreign countries, and it is recommended by the French Health Authority (2018). Having taken into account knowledge improvement in neurodevelopment and autism spectrum disorder (ASD) and the importance of observation by relatives in ecological context, the second version of the BSE was developed. This paper presents the construction and the validation study of the second version of the behavioral summarized evaluation scale, the BSE2 and the BSE2-P rated by parents., Methods: Construct validity of the BSE2 scale has been studied in a population of 244 children and adolescents with ASD according to DSM-5 criteria, aged from 30 months to 18 years. Discriminant validity has been analyzed using a population of 86 patients of the same age, with neurodevelopmental disorder (NDD) without comorbidity of ASD., Results: BSE2 comprises 30 items and is a two-dimensional scale as was BSE-R. Both dimensions, labelled "Interaction" (11 items) and "Modulation" (11 items), accounted for 41.7 % of the total variance. They describe autism severity and are in accordance with the two DSM-5 dimensions. Internal consistency (0.927 and 0.850 respectively) and inter-rater reliability (0.932 and 0.897 respectively) are good or excellent for both dimensions. Sensibility and specificity (0.758 and 0.767 respectively) range BSE2 among the tools with good psychometric properties. The parent version, BSE2-P, dedicated to ecological context is easily rated by parents., Conclusions: BSE2 scale for children and adolescents is a clinical tool with good psychometric properties. Its two-dimensional structure is in accordance with DSM-5 criteria. This scale covers all spectrum of ASD clinical forms in both children and adolescents. It can be used to identify ASD in complex neurodevelopmental disorders with several comorbidities and can help to distinguish autism symptomatology from other neurodevelopmental diagnoses. Furthermore, this scale allows to expand the rating context, involving parents to define and adjust the individualized therapeutic project. Thus the BSE2 is a valuable clinical tool for practitioners for both diagnosis and follow-up., (Copyright © 2021 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)

What is mood? Despite its crucial place in psychiatric nosography and cognitive science, it is still difficult to delimit its conceptual ground. The distinction between emotion and mood is ambiguous: mood is often presented as an affective state that is more prolonged and less intense than emotion, or as an affective polarity distinguishing high and low mood swinging around a baseline. However, these definitions do not match the clinical reality of mood disorders such as unipolar depression and bipolar disorder, and do not allow us to understand the effect of mood on behaviour, perception and cognition. In this paper, we propose a multidimensional and computational theory of mood inspired by contemporary hypotheses in theoretical neuroscience and philosophy of emotion. After suggesting an operational distinction between emotion and mood, we show how a succession of emotions can cumulatively generate congruent mood over time, making mood an emerging state from emotion. We then present how mood determines mental and behavioral states when interacting with the environment, constituting a dispositional state of emotion, perception, belief, and action. Using this theoretical framework, we propose a computational representation of the emerging and dispositional dimensions of mood by formalizing mood as a layer of third-order Bayesian beliefs encoding the precision of emotion, and regulated by prediction errors associated with interoceptive predictions. Finally, we show how this theoretical framework sheds light on the processes involved in mood disorders, the emergence of mood congruent beliefs, or the mechanisms of antidepressant treatments in clinical psychiatry., (Copyright © 2022 L'Encéphale, Paris.

The COVID-19 pandemic caused by the novel coronavirus SARS-CoV-2 has caused an unprecedented global crisis, and a proliferation of conspiracy theories. These conspiratorial beliefs has contributed to weakening the credibility of government public health measures, limiting citizens' access to reliable sources of information, and disrupting the response of health systems to the crisis. Several hypotheses have been proposed in psychology and social science to understand the genesis of these beliefs during a pandemic, including generational, socio-cultural and political characteristics of individuals, and psychological factors such as the desire to preserve one's safety, to maintain a positive self-image, or even to strengthen its social role. However, recent discoveries in cognitive science about belief updating mechanisms offer new insights into the generation of conspiratorial beliefs across time and culture. In this paper, we offer a definition of conspiracy theory and a classification of conspiracy beliefs during the COVID-19 pandemic. We show how the mechanisms of belief updating may explain the genesis of conspiracy theories, and we propose several hypotheses supported by contemporary research in cognitive and social science., (Copyright © 2022 L'Encéphale, Paris.

The question of how the mind works is at the heart of cognitive science. It aims to understand and explain the complex processes underlying perception, decision-making and learning, three fundamental areas of cognition. Bayesian Brain Theory, a computational approach derived from the principles of Predictive Processing (PP), offers a mechanistic and mathematical formulation of these cognitive processes. This theory assumes that the brain encodes beliefs (probabilistic states) to generate predictions about sensory input, then uses prediction errors to update its beliefs. In this paper, we present an introduction to the fundamentals of Bayesian Brain Theory. We show how this innovative theory hybridizes concepts inherited from the philosophy of mind and experimental data from neuroscience, and how it translates complex cognitive processes such as perception, action, emotion, or belief, or even the psychiatric symptomatology., (Copyright © 2021 L'Encéphale, Paris.

The Opioid substitution treatment (OST) has been highly argumentative in ways that raise important ethical issues. The stigma in treating opioid addiction continues to be a major barrier to effective management plan. It prevents individuals from seeking treatment and is associated with poor mental and physical health. OST are considered to improve outcomes in opioid dependency. They are legitimate therapeutic options because they comply with the four principles of bioethics: autonomy, no maleficence, beneficence and justice. OST plan should conceived in a way that outcomes only giving a medication to the patient. It has many ethical aspects that should be valued: fairness, respect and solidarity. However, OST may be misused or diverted, resulting in negative treatment outcomes, here comes the important role of the multidisciplinary treatment plan to contain and prevent from misuse. We will be discussing in this paper the ethical aspect of the OST and the values that should be promoted, in order to cherish and enhance the dignity of the human being, by replacing a deadly disease with a chronic one giving the patient a chance to lead a normal life., (Copyright © 2021 L'Encéphale, Paris.

Depressive disorder is characterized by a polymorphic symptomatology associating emotional, cognitive and behavioral disturbances. One of the most specific symptoms is negative beliefs, called congruent to mood. Despite the importance of these beliefs in the development, the maintenance, and the recurrence of depressive episodes, little is known about the processes underlying the generation of depressive beliefs. In this paper, we detail the link between belief updating mechanisms and the genesis of depressive beliefs. We show how depression alters information processing, generating cognitive immunization when processing positive information, affective updating bias related to the valence of belief and prediction error, and difficultie to disengage from negative information. We suggest that disruption of belief-updating mechanisms forms the basis of belief-mood congruence in depression., (Copyright © 2021 L’Encéphale, Paris. Published by Elsevier Masson SAS.

Philosophy of Mind is currently one of the most prolific fields of research in philosophy and has witnessed a progressive hybridization with cognitive science. It focuses on fundamental questions to neuroscience and psychiatry, such as the nature of mental states and cognitive processes, or the relationships between mental states and the world. Anticipating the accumulation of experimental data from neuroscience, it provides a framework for the generation of theories in cognitive science. Philosophy of mind has thus laid the foundations of the conceptual space within which cognitive sciences have spread: a large part of contemporary theories in cognitive science result from a hybridization of conceptions forged by philosophers of mind and data produced by neuroscientists. Yet contemporary psychiatry is still reluctant to feed on the philosophy of mind, other than through the fragments that emerge from neuroscience. In this paper, we describe the evolution of contemporary philosophy of mind, and we detail its contributions around three central themes for psychiatry: naturalization of mind, mental causality, and subjectivity of mental states. We show how philosophy of mind provide the conceptual framework to link different levels of explanation in psychiatry: from biological to functional, from neurophysiology to cognition, from matter to mind., (Copyright © 2021 L'Encéphale, Paris.

Introduction: Acceptance of the rape myths (ARM) refers to a set of attitudes, beliefs and stereotypes that tend to make women responsible for rapes or sexual assaults, and to rationalize, minimize or justify the behaviors of sexual offenders. ARM can also promote intimate partner violence (spousal rape). Domestic violence is generally associated with an insecure attachment style (avoidant or ambivalent) in both perpetrators and victims. The attachment insecurity of perpetrators of spousal violence can favor the use of violence against partners. The perpetrators also have a tendency to attribute the responsibility of their acts to their partners. Gerger, Kley, Bohner and Siebler (2007) developed the "Acceptance of Modern Myths about Sexual Aggression Scale" to measure the ARM in a more subtle way, in particular by reducing social desirability bias. The aim of this study is both to explore the psychometric qualities of the French version of the AMMSA and to study the relationships between the ARM, attachment styles and spousal violence in young adults and perpetrators of domestic violence (with the hypothesis that the latter have a greater ARM and a more insecure attachment style with the intimate partner)., Methods: Participants. The participants (n=275) were divided into two samples: sample 1 comprised 243 French psychology students and psychiatry residents, mean age 26.94years (±4.06years, range 19 to 38), with 79 % females (173 women and 50 men). The majority (69%) were in a relationship, and their level of study ranged from 13th grade to 19th grade; sample 2 comprised 32 men treated in a therapy center for perpetrators of spousal violence (in the "Centre-Val-de-Loire" region in France). They had a mean age of 40.84years (±11.06years, range 22 to 61). The majority (59%) was in a relationship and their level of study ranged from 5th grade to 18th grade (mean level=11)., Instruments: To measure the ARM Myths, we used the AMMSA, which is composed of 30 items structured into a single overarching factor. To assess the styles of attachment to the partner, we used the Experiences in Close Relationships (ECR) scale, which comprises 36 items structured in two dimensions: (i) attachment-related anxiety, and (ii) attachment-related avoidance in the couple. The tools were self-administered. Students completed the questionnaire via the Internet using the Sphinx software during an online survey. Clinical subjects completed the questionnaire in their therapy center. All participants were volunteers and gave their informed consent before anonymously completing the paper or online self-assessment questionnaire., Results: We carried out a principal components factor analysis using Varimax rotation on the data obtained from the answers to the 30 items of the AMMSA of all respondents. The analysis identified a single factor with an eigenvalue of 9.04 and which explained more than 30% of the total variance. This factor saturated (>0.30) 29 of the 30 items of the AMMSA, and the Cronbach alpha (which assesses internal consistency) was 0.91. The comparison of AMMSA scores between the clinical group (men with a history of spousal abuse) and male and female students showed differences, while there were no significant gender differences in the non-clinical group. The mean level of insecurity of attachment to the partner was also higher for the men in the clinical group than those in the non-clinical group (students). Results found correlations between the ARM and ECR for attachment-related anxiety in the non-clinical group (both men and women), a weak and negative correlation between age and attachment-related anxiety, and a correlation between age and AMMSA only for women., Discussion: The results concerning the qualities of the AMMSA are consistent with previous work. In addition, perpetrators of spousal violence have a stronger ARM. The links between (a) older age and a low level of education and (b) the ARM have already been highlighted. However, psychology students and psychiatry residents are probably more likely than others to develop pro-social, egalitarian, sensitive and tolerant attitudes, and therefore to be less in touch with rape myths. Both men and women have sexist representations and acceptance of the rape myths. The ARM is associated with common negative gender stereotypes, notably ambivalent sexism (with its two dimensions: hostile and benevolent sexism). This study has limitations linked both to the small clinical sample and the recruitment of non-clinical subjects from psychological and medical academic fields (with a specialty in psychiatry). Nonetheless, it is also one of the interests of this study to show that the ARM concerns everyone, including students, regardless of their academic or professional orientation., Conclusion: The AMMSA, which has been validated in different languages and in different contexts, has always shown good psychometric qualities. This French adaptation shows the same characteristics in terms of unifactorial structure, saturation of scale items and internal consistency. Further studies are needed to confirm external validity and test-retest reliability. It would also be desirable to conduct studies with larger and more representative samples. The AMMSA could be an excellent prevention tool by raising awareness of the continuing extent of negative gender stereotypes, violence against women and rape myths., (Copyright © 2021 L'Encéphale, Paris.

In contrast to the classic models in psychopathology, the network model considers that the temporal interactions between symptoms are the causes of their occurrence. This model could also be particularly suitable for understanding the processes involved in post-stroke depression. The aim of this paper is to perform a network analysis in order to describe the temporal dynamic of the links existing between depression symptoms during the acute phase after stroke. Twenty-five patients (64% male, mean age 58.1±14.9 years old) hospitalized for a minor stroke (no neurocognitive or motor impairment) were involved in an Ecological Momentary Assessment methodology-based study. They used a smartphone application in order to complete four brief questionnaires each day during the week after hospital discharge. The questionnaire included 7-point Likert scales to measure the severity of the following depressive symptoms: sadness, anhedonia, fatigue, diminished concentration ability, negative thoughts on oneself, pessimism. We used Multilevel Vector Autoregressive analysis to describe the temporal links between those symptoms. We used the software R 3.6.0 with the mlVAR package. The p-value was set at .05. The results show two independent symptoms networks. The first one involves the anhedonia, fatigue, negative thoughts on oneself and sadness. It shows that: anhedonia predicts the activation of later fatigue (β=0.135, P=0.037) and later negative thoughts (β=0.152, P=0.019); negative thoughts predict later negative thoughts (β=0.143, P=0.028) and later sadness (β=0.171, P=0.021); fatigue predicts later fatigue (β=0.261, P<0.000). Pessimism and diminished concentration ability compose the second network, and the results show that pessimism predicts later pessimism (β=0.215, P=0.012) and later diminished concentration ability (β=0.178, P=0.045). On the one hand, anhedonia thus plays an important role in the initial and progressive activation of the other symptoms of its network. On the other hand, the cognitive symptoms (negative thoughts and pessimism) cause the deterioration of the mood and the deficit of attentional abilities. Using behavioral and cognitive strategies to support patients after hospital discharge would reduce the risk of depressive complications after a stroke. This study provides convincing empirical elements for the interest of the network model for research in psychopathology and the clinical implications and perspectives allowed by network analysis., (Copyright © 2020 L'Encéphale, Paris.

Introduction: Child sexual abuse is a major health problem that remains under-declared and under-reported worldwide. In this paper we have taken an interest in establishing the profile of the victims in a clinical population of children consulting for sexual abuse., Method: We conducted a descriptive retrospective study in the child and teenager psychiatry department of the Mongi-Slim hospital (Tunis, Tunisia). We included all patients referred for treatment or medical expertise during the period from January 2013 to June 2019 and recorded sociodemographic data and clinical characteristics on pre-established charts from patient files., Results: The total number of consultants was 150 patients with 61,33 % of female subjects (n=92). The average age was 9,9 years old with extremes ranging from 2 to 18 years old. The assault was unique in 62,7 % and happened in a place known by the victim in 47,33 %. Sexual abuse with non-penetrating contact was the most frequent (48 %). The average age at which the first sexual abuse happened was 9 years old. In the vast majority of cases, the abuser was a male. Concerning the identity of the abuser, he was someone of the family in 37,3 % of the cases and in half of these cases, he was the father. In the other cases where the abuser wasn't a family member, the identity was known by the child and/or his family in 48,66 %. A psychiatric diagnosis was made in 58 % of the cases with a percentage of 52,1 % among girls and 60,3 % among boys. Main diagnoses were acute stress disorder in 10,6 %, post trauma stress disorder in 19,3 %, adjustment disorder in14,6 % and a major depressive disorder in 8 %., Conclusion: Knowing the profile of victims of child sexual abuse and taking into consideration the social and psychiatric impact can help in adapting the means to intervene properly in order to take care of the victims and prevent such abuse., (Copyright © 2020 L'Encéphale, Paris.

Objectives: Schizophrenia spectrum disorders are associated with incapacitating social impairments, mostly due to Theory of Mind (ToM) deficits. Theory of mind difficulties often precede the beginning of schizophrenia spectrum disorders and contribute highly to the social withdrawal of patients. They also predict bad outcome for individuals suffering from this condition. The use of samples of individuals presenting subclinical forms of schizophrenia spectrum disorders constitute an opportunity to study theory of mind capacities. Notably, the study of theory of mind deficits in schizotypy allows a better understanding of predictive markers of schizophrenia spectrum disorders. They also contribute to the identification of primary processes involved in social difficulties associated with these disorders., Methods: We searched PubMed, Science Direct and Google Scholar databases for peer-reviewed articles studying the association between theory of mind performance and schizotypal traits up to the 1 April 2020. The following syntax was used: schizotypy AND ("theory of mind" OR "social cognition" OR "irony" OR "false belief" OR "social inference" OR "hinting task"). We also checked the references from these articles for additional papers. Only English and French written articles were considered., Results: Twenty-three articles were included in the review. The majority of these studies (n=20) used behavioral measures of theory of mind (i.e. percentages of correct responses on a theory of mind task). Only a few (n=3) recent studies used brain imaging to study theory of mind in psychometric schizotypy. In those 23 studies, 18 report theory of mind difficulties in individuals with high schizotypal traits. Ten out of these 19 studies report an association between positive schizotypy and theory of mind deficits/hypomentalizing. The positive dimension was the most associated with theory of mind difficulties. The negative dimension was associated with theory of mind deficits in six studies out of 19 (33 %). The association between disorganization and theory of mind deficits was weak, mostly because of a lack of studies measuring this dimension (only one study out of 13 measured this particular trait). The association between hypermentalizing and schizotypy was poorly characterized, due to high heterogeneity in how this feature was conceptualized and measured. In summary, some authors consider good performance on a theory of mind task as a sign of hypermentalizing, while other authors consider that this feature relates to the production of erroneous interpretations of mental states. We advocate in favor of the second definition, and more studies using this framework should be conducted. Interestingly, the three studies using fMRI showed no significant behavioral differences between high and low schizotypal groups on theory of mind performance, while the patterns of brain activation differed. This shows that in individuals with schizotypy, theory of mind anomalies are not always captured just by behavioral performance. Brain imagery should be included in more studies to better understand theory of mind in schizotypy. In general, high heterogeneity in ways of assessing schizotypy, and in the tasks used to evaluate theory of mind, were found. Notably, some tasks require shallower theory of mind processing than others. It is a priority to design theory of mind tasks that allow for manipulating the difficulty of the items within one task, as well as the level of help that can be given, in order to allow for a better assessment of the impact of theory of mind difficulties and the ways to compensate for them., Conclusions: The studies included in this review confirm the association between psychometric schizotypy and theory of mind. But the high heterogeneity in methods used in these studies, and notably the diversity in ways of assessing schizotypal traits and theory of mind, hinder a precise description of such an association. Additional studies are required. In particular, fMRI studies using tasks allowing for a precise description of altered and preserved theory of mind processes could be of great use in characterizing theory of mind difficulties associated with schizotypy., (Copyright © 2021 L'Encéphale, Paris.

Background: The update of the Post-Traumatic Stress Disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM5) emphasizes the definition of psychological traumatism as an objective and external event. Nevertheless, the scientific debate about the criteriology of PTSD, its clinical pertinence for application and the role of subjective dimension appears still open. Although the relation between psychotrauma and psychosis has been well examined, in the way of trauma as a risk factor for the development of schizophrenia, the potential traumatism represented by the psychotic experience seems to be less known., Objective: This paper aims to provide a state of the art about the PTSD in reaction to psychosis, defined as PTSD post psychosis (PTSD-PP), particularly in epidemiological and psychopathological terms., Methods: We performed a bibliographic research on Pubmed using the keywords "post-traumatic stress disorder", "psychological trauma", "schizophrenia review", "psychosis", "first episode psychosis"« », "recovery schizophrenia", with a first screening on titles and abstracts. An acute psychotic episode referred to a decompensation of any pathology of the DSM5-schizophrenia spectrum or other psychotic disorders or to a mood disorder with psychotic features. The articles exclusively interested in the traumatic impact of hospitalizations and treatment conditions were excluded., Results: The literature noted that PTSD-PP affected about a quarter to a third of the psychotic patients interrogated during the recovery of an acute psychotic episode. The analytic epidemiology showed that the main validated risk factors for PTSD were also relevant in the development of PTSD-PP, including past traumatic history, childhood trauma and feeling of helplessness during the traumatic event. Criticizing the methodological heterogeneity through studies, the observational approach brought out the lack of clinical pertinence of the DSM5A criteria defining the traumatic event for PTSD. This criteriology failed to consider the subjective dimension of the threat to psychological integrity generated by a psychotrauma. Historical case studies presented a complete post-traumatic symptomatology in reaction to psychosis, suggesting that the supposed psychotic residual symptoms after acute phase could referr to actual traumatic reactions. The PTSD-PP process observed in descriptive research and patients' interviews appeared congruent with the cognitive model of PTSD elaborated by Ehlers and Clark. Indeed, psychotic patients developed negative appraisals about themselves, others and the world because of the occurrence and the content of their psychotic symptoms. Shame, fear of recurrence, intolerance to uncertainty and perception of losing control of one's mind were demonstrated as significantly related to PTSD-PP. A perception of current threat then settled, leading to adaptation strategies, possibly psychotic themselves, to avoid intrusions and others indices about their past psychotic episode. Thus, reliving syndrome, avoidance, emotional numbing could simulate a new psychotic exacerbation to an outer-observer., Conclusion: A psychotic experience could be traumatic for patients and lead to complete PTSD. Although it appears as a non-consensual clinical entity, from a likely epistemological slip of the definition of "psychotrauma", the consideration of potential PTSD-PP presents an undoubted clinical relevance. Indeed, it could help practioners to precise the semiological analysis of patients recovering from an acute psychotic episode; to impact the prognosis of psychosis, thinking about impairment on the quality of life and the affective and suicidal comorbidities; and to modify the therapeutic approach in the recovery of schizophrenia. In addition, the literature about psychotic recovery seems particularly related to the concept of "post-traumatic growth" (PTG). The inscription of a psychotic episode in a traumatic frame requires a clinical approach as close as possible to the subjectivity of the patient experience, beyond the evaluation of psychotic symptoms and its remission. The question of trauma-focused therapies applied to PTSD-PP opens the field for future research., (Copyright © 2019 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)

Background: Sexual violence exists everywhere in the world. It depends mainly on the cultural and religious norms conveyed in the various societies. This is a neglected area of research. Available data are insufficient, especially in Arab-Muslim context., Methods: In this paper, we comprehensively review the scientific literature in order to clarify the cultural, religious and legal aspects of the concept of sexual violence against women in Tunisia, and ask the question of the urgent need to put in place strategies to counter this problem., Results: The National Office for Family and Population published in 2011 the results of the national survey on violence against women in Tunisia, including data on sexual violence and its impact on women's health and well-being. According to this survey, 14.2% of women reported having been sexually abused by an intimate partner during their lifetime and 9.0% reported having experienced it during the last 12 months. One out of every six Tunisian women has been the victim of a sexual violence in a conjugal setting. More men than women legitimized violence against women in contexts where family control, especially conjugal control, is exercised over them. In a study examining the impact of culture and religion on experiences and sexual practice of women in Tunisian society, the majority of respondents thought that sexuality in women was a religious duty and that they do not have the right to refuse their husbands or to rebel. Thus, women would be doubly sanctioned having neither the right to express their desire nor not to respond to their husband's desire. A survey of a representative sample of Tunisian women found that 56.9% of the participants reported being victims of domestic violence, particularly sexual violence (10.7%) consisting mainly of rape and sodomy, at least once in their lifetime. This survey showed that those victims expressed dissatisfaction with overall quality of life. Moreover, contrary to Western literature, sexual violence was the least reported form of violence by teenage girls in Tunisian schools. Indeed, cultural values of modesty, virginity and honor are socially much more demanded for girls, in Arab countries in general, reinforcing staggering silence and inaction around violence experienced by school-aged adolescents. In Tunisian society, the cultural "solution" to rape wants the woman to marry her rapist which safeguards her family's integrity by legitimizing the union., Conclusion: Sexual violence has detrimental effects on female victims' physical and mental health. Even if the information on this form of violence is not easy to obtain in our environment, and that rates of subjects reporting sexual violence in their lifetimes are not important, the problem of sexual violence must be considered as a public health problem requiring urgent interventions and a greater institutional will., (Copyright © 2018 L'Encéphale, Paris.

Introduction: The objective of this paper is to verify if traits and symptoms defined as pathological and maladjusted in certain contexts may produce adaptive effects in other contexts, especially if they occur in sub-threshold forms., Methods: A historical examination of how the symptoms of depression have changed in front of great social changes and an analysis of Sardinian migrants' thymic profiles toward several metropolises., Results and Conclusions: Mood disorders have been increasing since the "English malady" in the 17th century, and we suppose that some forms of mood disorders might have an adaptive advantage. Otherwise, the increase of such an epidemic would have been self-limited. From a sociobiological point of view, it is highly probable that the environment of a rapidly evolving society can select people who are explorers and able to support accelerated biorhythms and that the condition of social change stimulates psychological and psychopathologic changes. It is also possible that hyperthymic persons modulate and create the new environment. If this model can explain the epidemic of mood disorders, its verification should guide future research., (Copyright © 2019 L'Encéphale, Paris. Published by Elsevier Masson SAS.

Objectives: Homelessness is associated with several issues (psychiatric and neurological disorders, neurodevelopmental difficulties, malnutrition…) which are also risk factors for cognitive disorders. However, little is known about the relationship between the cognition of homeless people and these eventual explicative etiologies. The aim of this work is to complete the results of Depp et al. about cognition in homelessness by proposing a systematic review of the neuropsychological disorders of homeless people associated with an analysis of the etiologies likely to explain these disorders., Methods: We followed the PRISMA recommendations to build up this work. We analyzed the abstracts of 385 papers found on databases PSYCINFO and PubMed. Twenty-two studies have been selected for respecting our criteria (at least one valid neuropsychological test ; general group of homeless people and not a sub-group of this population ; study published in English). The prevalence quality has been evaluated through the criteria of Loney et al. Cognitive scores and etiological factors have been compared between studies., Results: The 22 studies represent only nine countries. More than half of them are considered as having a poor prevalence quality. In total, 4,256 participants have been evaluated. Their mean age was around 40 years, and 85 % of the participants were men. The results show a prevalence of cognitive disorders (MMSE) in 8.77 % of the sample. The mean IQ was 87.47 and the premorbid IQ 94.59. We also notice possible disorders affecting the episodic memory and the executive functions. Mean scores for short-term memory, speech and visuo-spatial functions are relatively low. None of the studies evaluated the praxia, the gnosia or the social cognition. The heterogeneity of studies and the lack of data did not allow us to give general conclusions about the etiology of these disorders. However, we see that around 40 % of the time subjects had histories of brain injuries and 89 % of childhood trauma. Intellectual disability is found in 49 % of the sample of a single study. Also, 70 % of the homeless population have been diagnosed with substance-related disorders and 65 % with psychiatric disorders. It appears that the only factors correlated with cognitive disorders would be the history of brain injuries and childhood traumas., Conclusions: We confirm that homeless people often suffer from cognitive difficulties, and some of these difficulties (memory, executive functioning) are severe. Yet the etiology of these disorders remain relatively unknown: even if we observe a high prevalence of psychiatric, substance-related, neurodevelopmental and neurological issues by the homeless population, only a few of them (brain injury history and childhood trauma) seem to be correlated with cognition in homelessness. The potential explicative factors have been too rarely explored to bring a powerful explanation of cognitive disorders in homeless people. Further research needs to be done in order to give a more precise neuropsychological profile of the homeless population and to better understand what the disorders are rooted in. Last but not least, all this research and knowledge should be applied more to the care of homeless people by providing neuropsychological assessment and rehabilitation and by training the team to detect cognitive disorders and to support the person with a cognitive disability., (Copyright © 2019 L'Encéphale, Paris.

Introduction: Psychomotor impairments in Autism Spectrum Disorders (ASD) have frequently been described in scientific literature. Such deficits impact upon the development of social motor function and interfere with the ability to adjust to everyday life. The inclusion of sensory-motor signs in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) confirms their importance in the diagnosis of ASD. Previous literature has shown the presence precocity of these signs, sometimes before the alteration of the social communication. To our knowledge, there are no existing clinical tools to measure sensory-psychomotor deficit, specifically in ASD. The current paper presents the construction and validation of a new scale, designed to evaluate sensory-psychomotor signs in Autism: 'the Sensory-psychomotor Particularities Scale in Autism' (SPSA)., Method: The scale is composed of 160 items describing common sensory-psychomotor signs in autism. These items are grouped into 20 variables: touch, nociception, vestibular sensitivity, proprioceptive sensitivity, vision, auditory, multimodality, tone, posture, balance, global coordination, manual dexterity, body schema, bodily self-consciousness, relational adjustment, emotional expression, use of objects, space, time and tonico-emotional regulation. For each item, the psychomotor therapist evaluated sensori-psychomotor signs according to a five-level Likert scale (0="the sign is never expressed by the person", 1="weakly expressed", 2="moderately expressed", 3="severely expressed" and 4="the sign is very characteristic of the person and very severely expressed"). This is completed by a family interview in order to assess the impact of these signs on everyday situations. The study included 111 children with autism. The presence of neurological and genetic diseases was exclusion criteria. For each child, a global developmental evaluation was carried out by an expert clinical team specializing in ASD. Standardized clinical tools were used: Autism Diagnostic Observation Schedule (ADOS), Childhood Autism Rating Scale (CARS), Behavior Summarized Evaluation scale (BSE-R), Repeated and Restricted Behavior scale (RRB), Movement Assessment Battery for Children (M-ABC), Motor Development Rating scale (MDR), Sensory Profile (SP). Developmental quotients (DQ) were evaluated using various tests depending on age and ability., Results: Factor analysis produced three clinically relevant factors: F1: "sensory-emotional synchronization", F2: "multisensory integration" and F3: "motor skills": each containing a similar quantity of items. They account for roughly equal percentages of variance (18.9%, 18.0%, 16.8%, respectively). The factorial structure does not change if the 26 children with comorbid developmental coordination disorder are removed. The three factors show good internal consistency and excellent inter-rater reliability. F1 is comprised of 6 items: touch, nociception, proprioceptive sensitivity, vision, emotional expression and tonico-emotional regulation. This factor is significantly associated with items of the Sensory Profile (touch processing, poor registration, sensory seeking). F2 is comprised of 5 items: multimodality, bodily self-consciousness, relational adjustment, use of objects and space. This factor is associated with ADOS, BSE-R and RRB scores, and the item "touch processing" of the Sensory Profile. F3 is comprised of 4 items: tone, posture, global coordination, manual dexterity. This factor is associated with the M-ABC, the MDR and the item "low endurance" of the Sensory Profile., Conclusion: The SPSA is a relevant clinical tool to assess the severity of sensory-psychomotor clinical signs in order to describe the individual profiles of children with ASD. It represents a critical step in advancing knowledge of the complex and heterogeneous pattern of psychomotor development in autism. It could make a valuable contribution to the field, both in research and clinical practice., (Copyright © 2019 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)

Background: In France, on the first of January 2018, 772 underage persons were in jail or about 1.1 % of the incarcerated population. The prevalence of psychiatric disorders among those inmates is high. As a result psychiatric care (and particularly full-time hospitalization) is essential for this population. The unités hospitalières spécialement aménagées (UHSA) are full-time inpatient hospitalization units for inmates in France. Adults but also underage inmates can be admitted to UHSA for voluntary or involuntary hospitalization. However, no study about the characteristics of young patients admitted to UHSA is currently available. The aim of this study is to describe the population of children and adolescent patients hospitalized in these facilities and to evaluate the care provided., Method: We conducted a retrospective study, including all the patients under 18 years of age, who have been hospitalized in UHSA since its creation in 2010 until 31 December 2016. Anonymized data concerning socio-demographic profile, clinical symptoms and care provided have been collected from the medical records of each patient., Results: Overall 80 underage patients were included, for 120 hospitalisations in UHSA. Those patients are mainly male (80%) with a mean age of 16.7 years. They are mostly hospitalized with their consent (59%) for stays of about 50 days and frequently after self-harm behaviours. The main diagnoses are anxiety disorders (26%) and psychotic disorders (25%). At the end, 86% of the patients are prescribed a psychotropic drug treatment and 40% of those medical drugs are prescribed outside the guidelines. Finally, several specific problems were identified. Especially, contact with families and educators or access to education programs are very challenging., Conclusion: This study highlights the current difficulties encountered in the management of inmate underage patients in full-time psychiatric hospitalization. In this paper, we propose areas for improvement through (1) specific arrangements to receive young patients (specific service's management in order to reinforce the observation of those young people, to facilitate contact with their families, to improve the access to education programs, etc.); (2) specific arrangements in the treatment offered to young patients in UHSA (specific training course for nurses, specific therapeutic programs, etc.); (3) the development of networks working with psychiatric services inside and outside the prison, educators, families and prison services, in order to promote the continuity of cares., (Copyright © 2018 L’Encéphale, Paris.

22q11.2DS is one of the more frequent genetic syndromes associated to psychiatric symptoms. It has been associated to an increased risk to develop schizophrenia in adolescence or early adulthood. However, psychiatric symptoms appear early on, and should be recognized as soon as possible by child psychiatrists in order to improve the present well-being of children and their family, and to prevent further risks of developing severe and chronic psychiatric diseases later on. In this paper, we present a review of the recent literature concerning the 22q11.2DS syndrome focused on the risk factors that may be associated to an increased risk of psychotic transition. We advocate for the development of systematic specialized child psychiatry consultations for these patients, included in networks with geneticists, adult psychiatrists, and family associations, in order to improve their psychiatric prognosis and to support the development of translational research., (Copyright © 2018 L'Encéphale, Paris.

Predictive prospective studies of schizophrenia date back to the late 1950s. At the turn of the Millennium, an Australian research group initiated programs of early detection of schizophrenia and early therapeutic intervention. The theoretical foundations of early schizophrenia detection usually remain unaddressed. In this paper, we focus on the issue of prediction of future schizophrenia in the general population on the basis of a symptomatic picture. Several notions used in this research program such as disease, symptom, and clinical staging derive from a medical model, which in our view is not entirely adequate for grasping the nature of schizophrenia. Schizophrenia is a spectrum of disorders with a shared core Gestalt comprising dis-order of selfhood and intersubjectivity. This core Gestalt has manifold manifestations, often predominantly in the existential or experiential domain. It is not feasible to apply medical concepts to this symptomatically poorly demarcated spectrum for which we do not know robust biological validators. Moreover, there is increasing evidence that the current DSM and ICD criteria of schizophrenia distort the original concept of schizophrenia and are formulated on a very high severity level. This often results in incorrect diagnoses of young help-seeking patients. In sum, it seems more appropriate to detect psychosis among already help-seeking patients than to implement detection programs in the general population. We discuss a reorientation of psychiatry towards more refined psychopathological knowledge and assessment that are needed in order to optimize the treatment of young help-seeking patients., (© 2018 L’Encéphale, Paris.)

Objectives: Suicidal adolescents admitted in an Emergency Department (ED) present a high risk of suicidal reattempts. Poor observance of follow-up in this particular group imped the efficacity of the treatment. We propose to summarize the international literature on ED interventions promoting suicidal adolescents' adherence to care., Method: We carried out a comprehensive review of papers listed in PubMed, PsycInfo, and CINHAL databases using keywords about adolescence, suicide, and ED. We also manually consulted the main journals specialized in suicidology (Crisis and Suicide and Life-Threatening Behavior) and adolescence (Journal of the American Academy of Child and Adolescent Psychiatry, Journal of Adolescent Health, Neuropsychiatrie de l'Enfance et de l'Adolescence). We selected the relevant articles describing or evaluating one or more interventions initiated in the ED and designed to promote adolescent adherence to post-emergency care. The results are presented in a narrative review form., Results: Interventions are organized in three groups: interventions that take place solely at the ED (problem-solving interventions and educational interventions directed to families) and interventions that take place during and after emergency care (we included in this group the ED-Care program, the FISP program, and the SAFETY program), to which should be added interventions that take place prior to care, in particular specific trainings for medical and paramedical teams. Small samples and barriers in measuring adherence to care make statistical comparisons difficult, yet the interventions that seem most effective are those that target the time both during and after ED discharge, those which are implemented most rapidly after discharge, those which actively include parents, and those which involve an implication of the families about barriers to follow-up., Conclusion: Our results show an effectiveness of complete programs on short-term compliance but no conclusion can be drawn on long-term effects. Most comprehensive care programs are based on the principle of adolescent compliance, which remains problematic. Until today, no ideal protocol exists to improve short-term as well as long-term compliance to care among adolescents after a suicide attempt. We have to improve our understanding of facilitators and barriers to follow-up using quantitative as well as qualitative research studies. Although it is well established that parents' involvement in the early stages of care is essential, little is known about the underlying processes. In these situations, qualitative studies could help to better target interventions that lead more particularly to follow up compliance in adolescence., (Copyright © 2018 L'Encéphale, Paris.

Mentalization is a process by which a subject makes sense of both his own mental representations and of those around him. Disturbances in the mentalization process are found in several psychiatric disorders, notably borderline personality disorders for which mentalization-based treatments (MBT) have been developed and evaluated. Children with Autism Spectrum Disorder (ASD) display a theory of mind impairments, which corresponds to disturbances in the mentalization process. Although no MBT protocol for patients with ASD has been described in the literature, such treatment appears promising to improve theory of mind and functional outcome of these children. In this paper, we propose to discuss the theoretical ground of MBT therapeutic effect in children with ASD without intellectual disabilities and to describe a clinical protocol to test this perspective., (Copyright © 2017 L'Encéphale, Paris.

Objectives: Recovery is a process through which people experiencing mental illness learn to live with their disorder and reach social insertion and citizenship. This positive approach focuses on a person's competencies and strengths rather than on the symptoms. Within this philosophy, peer support has been unevenly developing in mental health services worldwide with roots in the South-American social programs for homeless people and in the American recovery circles in the field of addiction. Therapeutic efficiency of peer support has been proven by several studies including a control group, as being at least as good as traditional services and even better in some specific areas such as reduction of need for emergency services and ability to reach "difficult" patients. The integration of former psychiatric services users in mental health services can take several forms, from the participation to scientific research studies to the direct involvement in a professional team at mental health facilities. In this context, our research aims to sum up the situation in France in comparison with other countries., Methods: We conducted a worldwide literature review in English and in French on peer support experiences and policies in mental health services, using medical and psychological databases (PsycInfo, PsycArticles, SantéPsy, Cairn, Medline, Wiley Interscience and PubPsych) on a recent period: 2005-2016. In total, 32 relevant scientific papers have been included in our research. In some cases, we have also used official reports, blogs, Internet sites, and mass media articles when they were relevant., Results: Our results show that this movement has been long to develop in France, with controversies having been raised since the beginning on the role that peers should play and confusion with existing social integration programs in the associative sector. Drawing inspiration from the Canadian model, a recent "peer mentor" initiative has been analyzed after 2 years of existence: many benefits for services users such as the optional aspect of this care process, a more authentic therapeutic relationship, a less normative frame, an active partnership, and a more optimistic philosophy aiming to make "small steps" towards improvement have been reported. Health professionals and peer mentors themselves have found benefits during the process. However, several limits such as difficulties to find a place with regards to the psychiatric team and difficulties to take advantage of the peer specificity, resulting in a significant attrition of the number of peer mentors, could be observed. A few other important initiatives focused on social insertion and using the help of professional peer support have been developed in recent years, but they seem to have encountered the same issues about positioning themselves both in terms of day-to-day integration in the professional environment and in the job title given by institutions which rarely corresponds to their experience and specificity. In addition, it remains difficult to obtain reliable information, as only a few papers have been published on this matter. Also, while some evaluation studies are currently being carried out, independent quantitative studies of the few running programs seem to lack in this field., Conclusions: In our presentation, taking into account the difficulties that were raised in French programs and the lessons of practical experiences at work in other countries, we propose recommendations for larger and more effective implementations of peer support programs in France. As this new kind of care is emerging and seems promising in terms of benefits for not only the users but also the peer supporters and the teams of health professionals, we also insist on the need for a systematic scientific and objective evaluation of the programs., (Copyright © 2018 L'Encéphale, Paris.

Objectives: Video games and virtual reality have recently become used by clinicians for training or information media or as therapeutic tools. The purpose is to review the use of these technologies for therapy destined for schizophrenia patients., Methods: We conducted a review in October 2016 using Pubmed, Scopus and PsychInfo using the following Medical Subject Headings (MESH): "video games", "virtual reality" and "therapy, computer-assisted/methods", each associated with "schizophrenia". Papers were included in the review if: (a) they were published in an English, Spanish or French-language peer-reviewed journal, (b) the study enrolled patients with schizophrenia or schizo-affective disorder, (c) the patients used a therapeutic video game or therapeutic virtual reality device., Results: Eighteen publications were included. The devices studied are mainly therapeutic software developed specifically for therapeutic care. They can be classified according to their therapeutic objectives. These targets corresponded to objectives of psychosocial rehabilitation: improvement of residual symptomatology, cognitive remediation, remediation of cognition and social skills, improvement of everyday life activities, support for occupational integration. Very different devices were proposed. Some researchers analysed programs developed specifically for patients with schizophrenia, while others were interested in the impact of commercial games. Most of the studies were recent, preliminary and European. The impact of these devices was globally positive, particularly concerning cognitive functions., Conclusions: Computer-assisted therapy, video games and virtual reality cannot replace usual care but could be used as adjunctive therapy. However, recommending their use seems premature because of the recent and preliminary character of most studies. Moreover, a link is still lacking between this field of research in psychiatry and other fields of research, particularly game studies. Finally, it might be interesting to analyse more precisely the neuropsychological impact of existing commercial games which could potentially be useful for psychosocial rehabilitation., (Copyright © 2018 L'Encéphale, Paris.

Objective: Since the publication of the DSM-5 (APA, 2013), the dimensional conception of the personality disorders is co-existing with the classical categorical paradigm. Tools have been proposed for the evaluations of five big pathological factors to be explored further according to the APA (negative affectivity, detachment, antagonism, disinhibition, psychoticism). Despite numerous works using these questionnaires (30 works in 3 years according to Al-Adjani et al., 2015), none of them have yet been translated into French. Also, the main objective of the paper is to present a French translation of the Personality Inventory for DSM -5 by Kruegger et al. (2013) in its brief form of 25 items (PID-5 BF)., Method: To reach this goal, we have employed the classic translation-retranslation method (Vallerand, 1989) and tested the consistence and the validity of this French version among a non-clinical sample (n=216) of young adults (age=31.4, SD=4.8), in joining some other questionnaires in their short forms to study the external validity of the PID-5 about the psychological distress (SCL-10, Nguyen, 1983), the categorical diagnosis of personality disorders (SAPAS, Moran et al., 2003) and the classical Big Five dimensions of the personality (BDI 10, Ramamstedt and John, 2007). The internal consistency of this translation has been studied through the classical outcomes on factor analysis for the dimensional repartitions of the items in 5 scales and Cronbach's alpha for the consistency of each found dimensions. The external validity has been explored by studying Pearson's correlations between the outcomes on each dimension of the PID-5 BF and both the clinical dimensions of SCL-10, personality dimensions of the BFI-10 or personality disorders (SAPAS)., Results: Factor analysis led to the same repartition of the 25 items as the original versions. Each of the dimensions is consistent enough (α>.65) to be taken into account as clinically significant. The items of the French version of the PID-5 BF follow the expected repartitions in 5 dimensions, which are consistent enough. Although their mean scores are significantly not different from the outcomes found by Krueger with the PID-5 200 items among another non-clinical population (n=264), one cannot say that is enough to ensure the external validity of our translation, for it uses neither the same tools nor sample. A comparison with a French translation of the PID-5 would be more significant. However, the external validity of the French version seems to be significant enough. Global score on the PID-5 is correlated both to the Global Severity Index of the SCL-10, which reflects global psychological distress, and SAPAS's score, which evaluates the suspicion of personality disorder. The clinical validity of the PID-5 is confirmed by the relationships between negative affectivity and anxiety or depression or antagonism and hostility, although the clinical scale of the SCL-10, with one item by dimension, is less sensitive than the complete original version in 90 items (DeRogatis, 1974). PID-5 score and domains are also correlated with the Big Five personality dimension and global score of personality disorders which led us to think that it is coherent with the evaluation of personality suffering (r=.34) and dimensions. The links between negative affectivity and neurosism (r=.48) or between desinhibition and extraversion (r=.32) or the negative correlation between psychoticism and conscientiousness (r=-0.16) are consistent with the expectations related both to the descriptions of the domains by the DSM and outcomes on the comparisons between PID-5 200 item scales and NEO-PI or BFI 45 items., Discussion: This translation offers enough consistency and validity to be used in future studies. This could lead us to either continue studying a more representative general population or testing its validity in focusing on a clinical sample where personality disorders are prevalent, such as homeless men or substance users. As soon as a French version of the PID-5 200 items is published, one can compare the outcomes on PID-5 BF and PID-5 to lead to estimations of personality disorders and pathological domains among French populations and explore personality disorders throughout a dimensional paradigm instead of syndromic perspective. One can also see whether the items that have been kept for each dimension are as saturated in the French version as in the original one. Among general populations, comparisons with clinical distress, syndromic personality disorders or dimensional aspect of personality could be done with complete versions of PID-5, Symptom Check-list, Personality Disorders Questionnaires or Big Five Inventory; therefore, the brief forms of any questionnaire could be used among any people whose psychological distress or side effects impaired their attention and concentration., (Copyright © 2016 L'Encéphale, Paris.

Introduction: Depression and Alzheimer's disease are both very frequent in elderly people. Cognitive deficits are the hallmark of Alzheimer's disease, but they are also common in depressed elderly people who often present cognitive deficits such as memory, attention and executive function problems. On the other hand, people with early Alzheimer's disease demonstrate emotional and behavioral disorders generally encountered in depression such as loss of energy, apathy, mood disorder, and irritability. Thus, in older adults with depression, the presence of cognitive deficits can make it difficult to distinguish cognitive decline that is associated with a depressive illness and the decline encountered in Alzheimer's disease because the clinical picture of the two disorders are similar. However, early distinction between the two disorders is very important from a prognostic and therapeutical point of view., Objective: After a brief description of the relationship between depression and early Alzheimer's disease in elderly people, this paper aims to present an updated literature review of data on differential diagnoses between these disorders., Method: We performed a non-systematical, yet as exhaustive as possible, literature search with Pubmed electronic database, screening studies from 2000 to 2016., Results: The majority of the studies concerned cognitive aspects, but only a few studies investigated others markers such as cerebral imaging, electroencephalography, cerebrospinal fluid markers. At the neuropsychological examination, a detailed analysis of the mnesic profile revealed a better benefit of semantic cueing in patients with late life depression in comparison to those with prodromal Alzheimer's disease and better performances in recognition memory. Moreover, longitudinal follow-up of patients with depression indicated that deficits in delayed recall memory, but not in executive functions, were associated with the subsequent development of Alzheimer's disease. Several studies showed that tests of executive functions could not differentiate between patients with late life depression and patients with prodromal Alzheimer's disease. A measure of global cognitive decline does not seem to be helpful in differentiating early Alzheimer's disease and depression, unlike an analysis of the neuropsychological profile on several composite scales, such as the Mini Mental State Examination. Furthermore, recent work has investigated the utility of olfactory or gustative markers with promising results and convenient tools for clinical practice. Concerning morphological brain imaging, only detailed volumetric analysis could show differences between the two diseases, but these techniques are not always available for clinical practice. It is the same for other recent techniques, such as quantitative electroencephalography, Near InfraRed Spectroscopy, Single Photon Emission Computed Tomography, or Transcranial Doppler Ultrasonography, which have received little attention so far as differential diagnostic tools. Finally, cerebrospinal fluid analysis could be useful, including beta amyloid levels., Conclusion: Despite numerous efforts in recent years, differential diagnosis of dementia from depression in the elderly remains difficult. Results of this review highlight the necessity of conducting more research in this area, with multi-method studies, using not only cognitive analysis but also cerebral imaging techniques., (Copyright © 2017 L'Encéphale, Paris.

Objectives: Mindfulness based interventions (MBI) have recently gained much interest in western medicine. MBSR paradigm is based on teaching participants to pay complete attention to the present experience and act nonjudgmentally towards stressful events. During this mental practice the meditator focuses his or her attention on the sensations of the body. While the distractions (mental images, thoughts, emotional or somatic states) arise the participant is taught to acknowledge discursive thoughts and cultivate the state of awareness without immediate reaction. The effectiveness of these programs is well documented in the field of emotional response regulation in depression (relapse prevention), anxiety disorders, obsessive-compulsive disorder or eating disorders. Furthermore, converging lines of evidence support the hypothesis that mindfulness practice improves cognition, especially the ability to sustain attention and think in a more flexible manner. Nevertheless, formal rehabilitation programs targeting cognitive disturbances resulting from psychiatric (depression, disorder bipolar, schizophrenia) or neurologic conditions (brain injury, dementia) seldom rely on MBI principles. This review of literature aims at discussing possible links between MBI and clinical neuropsychology., Methods: We conducted a review of literature using electronic databases up to December 2016, screening studies with variants of the keywords ("Mindfulness", "MBI", "MBSR", "Meditation") OR/AND ("Cognition", "Attention", "Executive function", "Memory", "Learning") RESULTS: In the first part, we describe key concepts of the neuropsychology of attention in the light of Posner's model of attention control. We also underline the potential scope of different therapeutic contexts where disturbances of attention may be clinically relevant. Second, we review the efficacy of MBI in the field of cognition (thinking disturbances, attention biases, memory and executive processes impairment or low metacognitive abilities), mood (emotional dysregulation, anxiety, depression, mood shifts) and somatic preoccupations (stress induced immune dysregulation, chronic pain, body representation, eating disorders, sleep quality, fatigue). In psychiatry, these three components closely coexist and interact which explains the complexity of patient assessment and care. Numerous studies show that meditation inspired interventions offer a promising solution in the prevention and rehabilitation of cognitive impairment. In the last part, we discuss the benefits and risks of integrating meditation practice into broader programs of cognitive remediation and therapeutic education in patients suffering from cognitive disorders. We propose a number of possible guidelines for developing mindfulness inspired cognitive remediation tools. Along with Jon Kabatt Zinn (Kabatt-Zinn & Maskens, 2012), we suggest that the construction of neuropsychological tools relies on seven attitudinal foundations of mindfulness practice., Conclusions: This paper highlights the importance of referring to holistic approaches such as MBI when dealing with patients with neuropsychological impairment, especially in the field of psychiatry. We advocate introducing mindfulness principles in order to help patients stabilize their attention and improve cognitive flexibility. We believe this transition in neuropsychological care may offer an interesting paradigm shift promoting a more efficient approach towards cognition and its links to emotion, body, and environment., (Copyright © 2017 L'Encéphale, Paris.

Objectives: Pain is a common experience, both physical and emotional. However we often feel powerless with our patients suffering pain. This paper aims to give a new heuristic and psychological understanding of pain., Methodology: According to new theories, recent researches as well as different points of view, we form an analogy between pain and emotion. Throughout historical considerations pain has always been perceived through theories and beliefs, changing its definition. This is also the case for emotion. Could they be two ways of expressing a single phenomenon?, Results: First, we must clarify the definition of emotion. In past, emotion was considered as a multiple-conditioned notion. To be considered as an emotion the pain had to fill numerous features, which differ according to the scientific opinions. The emotion may be considered as a physical expression or perceived only as the consequences of a real emotion, i.e., the subjective feeling. We propose as a way of thinking that emotion brings together these two concepts. We support a flexible vision of emotion. To investigate the field of the emotion different mental steps may be thought of: we should conceive of the emotion as a stimulus, as an emotional evaluation and as a tendency to action, which becomes an emotional response. These steps are colored by subjective feelings. It can be summarized in three levels: the situation decoding (1), the response organization (2) and the effectiveness of the response (3). Second pain can be considered as a complex notion involving personal and subjective feelings. We can use multidimensional patterns and consider emotion with its multiple features: the generating mechanisms, the pain perception, the pain behavior and the environment. Each stage can be divided in different ways. Hence pain treatment could be approached as an emotional treatment. Indeed, we can make a link between generating mechanisms and emotion situation decoding, between pain perception and emotion situation decoding and response organization, between pain behavior and environment and emotion response effectiveness and consequences. A heuristic analogy can be formed enriching therapeutic possibilities. First, emotion and pain could be considered as a unique phenomenon that can be expressed in different ways. We can let aside the opposition between psychological and physiological: these are two different levels of a same phenomenon. This point of view can be helpful to treat pain disorders because the skills to manage emotion disorders are well known., (Copyright © 2017 L'Encéphale, Paris. Published by Elsevier Masson SAS.

The Behavioral Summarized Evaluation is a rating scale specifically related to the assessment of autistic behaviors in children and young teenagers with Autism Spectrum Disorder, such as communication, social interaction and interests. It also facilitates progressive recording of the evolution of children with ASD involved in short-term therapeutical studies. In the absence of standardized tools to assess autistic behaviors and effects of therapeutics in Lebanon, the BSE-R validation is an urgent need. The purpose of this study is to validate the BSE-R to the Lebanese population., Method: Specialized translators and clinicians ensured forward and backward translation of the scale into Arabic. The participants consisted of 100 children with ASD, diagnosed upon DSMIV-TR criterion (age range: 35 to 153 months, DS: 28.0). Fifty-eight had intellectual disability (ID). Scores of autism severity as measured by CARS1 (Schopler et al., 1980) varied from 20-58.5. Trained raters on recorded individual and group situations performed BSE-R ratings., Results: BSE-R for Lebanese was found to have excellent inter-rater reliability. The internal validity highlighted a main factor which describes the severity of core autistic behaviors related to social interactions and communication, and behavioral specificities and particular interests with an internal consistency of 0.91 in a one-to-one setting and 0.92 in group settings. External validity of the scale as measured by correlations with CARS and the age of the children showed that this main factor is essentially determined by ASD severity, not by the severity of ID. It was named "relational deficiency" according to the initial paper of Barthélémy et al. (1997)., Conclusion: BSE-R in Arabic is a practical tool, useful to all team members working with ASD children in Lebanon and the Arab countries. It will also allow future research based on reliable tools at an international level., (Copyright © 2016 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)

For years, a large number of studies have demonstrated the harmful effects of alcohol consumption on the brain and therefore on behavior and cognition. These studies first aimed at identifying the consequences of alcohol abuse consumption, more specifically in pathologies such as alcohol-dependence or Korsakoff syndrome. Researchers then also started to focus on vulnerabilities to alcohol consumption, especially in hyper fast alcohol consumption called binge-drinking (BD). Indeed BD, which is a particularly dangerous form of alcohol consumption, is usually observed in adolescents and young adults. Typically, young people tend to adopt this way of drinking in order to reach a massive and expeditious intoxication. The aim of this paper is to present the bibliographic data available on the main risk factors to BD and to describe the main measurement tools for investigating these factors in clinical researches. The interaction between psychological dysfunctions and BD is not well understood. For a better understanding of the links between binge-drinking and psychological and personality factors in terms of vulnerability or risk, studies have investigated on affective factors (depression and anxiety), personality characteristics (impulsivity and sensation seeking) and drinking motives (coping, improvement, compliance and wellness). Although different factors are often associated with BD in adolescents and young adults, it is still not clear whether these factors are the consequences of alcohol consumption or a reflection of pre-morbid abnormalities predisposing individuals to excessive alcohol consumption. Furthermore, results are not unequivocal and various distinct personality profiles seem to emerge. Thus, these questions are still not fully resolved and further studies are needed to understand the complex relationships between BD and the various psychological or personality factors. The need for investigating these factors in clinical studies is nevertheless important with regard to therapeutic interventions. Indeed, the identification of specific profiles involved in a binge-drinking type of consumption could allow an adaptation of the contents of therapeutic programs by targeting a specific mechanism. For example, recent findings have revealed that when factors such as impulsivity are considered, therapeutic intervention is more effective., (Copyright © 2016 L'Encéphale, Paris.

Theoretical Background: The borderline personality disorder is a complex psychiatric disorder that represents a high number of patients in a psychiatric adult service. Even if some therapies have shown to be effective in the therapeutic care of the borderline personality disorder they only target certain symptoms (e.g. anxiety, sadness, self-mutilation). The aim of this paper is to introduce a therapeutic model little known in France: the mentalization based therapy (MBT) developed in 2004 by Bateman and Fonagy. This therapeutic model apprehends the borderline personality disorder in all its complexity and is based on two main concepts: Bowlby's attachment theory and the concept of mentalization. The MBT is based on the hypothesis that a deficit of mentalization leads to the development of borderline disorder. The capacity of mentalization, also known as reflexive function, is acquired in infancy through interpersonal relationships, in particular those of attachment, and is the ability to understand the mental state (emotions, needs, thoughts, etc.) of oneself and others which underlies explicit behaviour. This reflexive capacity is of a better quality when the person has a secure attachment style. Indeed, borderline patients have, mainly, a deficit of mentalization capacity associated with an insecure attachment style. Thus, the main objective of the Bateman and Fonagy approach is to develop and reinforce the mentalization capacity through a therapeutic relationship as a secure base, a group therapy and the concept of insight., Therapy Structure and Techniques: Classically, MBT is structured over a period of 18 months divided into 3 distinct phases distributed in two therapeutic axes: group and individual therapy. The initial phase aims to engage the patient in the therapy by evaluating attachment style, mentalization's ability, interpersonal functioning; providing psychoeducation about borderline disorder and establishing a therapeutic contract. To evaluate attachment style, the authors strongly recommend the use of the Relationship Scales Questionnaire. During the second phase, which includes individual and group therapy, the aim is to stimulate the capacity of mentalization through different techniques according to the patient's attachment style. These include therapeutic relationship, empathy, affect clarification and elaboration, positive and negative reinforcement. The final phase serves to review the patient's improvement and to prepare him progressively for the end of the therapy which can be experienced as an abandonment., Clinical Trials of Mbt and Developments: Effectiveness of MBT in treating borderline disorder has been shown in several studies with short and long term benefits. It can be adapted for other personality disorders and specific populations such as adolescents., Conclusion: This article introduces the key concepts and aims of mentalization based treatment. The therapy is briefly described in its different phases and the various techniques are discussed. Clinical trials have shown that MBT is effective in treating borderline disorder in adolescent and adult populations. Despite the effectiveness of this therapy, it is difficult to set up and requires substantial resources. Interpersonal therapy based on attachment provides a therapeutic model focused on problematic areas which can offer an alternative therapy and reduce the fields of investigations., (Copyright © 2016 L'Encéphale, Paris.

Objectives: Suicide-homicide could be defined as a "suicidal" behaviour, which also includes the death of at least one other individual and sometimes up to hundreds. This literature review intends to highlight some characteristic features that might be found amongst the various types of suicide-homicide. It is a complex phenomenon which can occur in different situations, from a familial and somehow intimate setting (filicide, uxoricide, marital homicide…) to a public one (workplace shooting, school shooting), including a wide range of victims, from a single victim in marital cases of suicide-homicide to hundreds of victims in certain types, such as suicide by aircraft or warrior-like multi-homicids in terrorist acts. This literature review offers a combination of data emanating from scientific publications and case studies from our practices in an attempt to insulate some common factors. A thorough examination of the offenses unravels complex processes, ideations, M.O and peculiar cognitive impairments in which the familial suicide-homicide could be rooted. Mass murders might be caused also by a psychopathological alloy, made of Grandiose Self and sub-depressive and even paranoid ideations. Concerning the terrorism and multi-homicide-suicide, this is far more complex phenomenon and is defined by a group-process enrolment and ideological conviction. Beyond epidemiological studies, both descriptive and statistical, this paper's objective is to isolate a hypothesis about a psychopathological ground from which a criminological mechanism could emerge. Despite the lack of blatant psychosis, some traits might be identified in suicide-homicide cases - such as paranoid, psychopathic, narcissistic, melancholic - which can intertwine, potentiate one with another forming a distorted view of the world. The offense dynamic is possibly composed of preparatory behaviours, triggers, the use of death as a narcissistic support, identity choices… METHODS: The data were collected from scientific publications, personal cases, and open source., Results: Despite the variety of behaviours included in this typology, we were able to identify a few mechanisms that could be found in two types of suicide-homicide [Private suicide-homicide (within the family circle) vs. Public space suicide-homicide (suicide by aircraft, school shooting…)]., Discussion: Suicide-homicide phenomenon is the result of the interaction of societal, ideological, psychopathological and criminological elements which burst out in a lethal and paroxystic gesture. Psychiatrists and psychologists may have an important part to play in modelling a pattern to better understand it., (Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS.

Background and Aim: Wernicke's encephalopathy (WE) is a medical emergency. The objective of this paper is to systematically review the literature published over the past 15 years pertaining to prophylactic and curative treatment of WE with thiamine., Methods: A systematic literature search was performed using Medline to include all studies published between January 1, 2000 and December 31, 2015., Results: Of the 316 abstracts identified, 20 met the final inclusion criteria. The evidence on the use of prophylactic thiamine was quite heterogeneous. The use of thiamine in this context largely depended on the evaluation of an individual's risk of developing WE. Use of prophylactic thiamine in low-risk patients is not universally indicated. When prescribed in this sub-population, the oral route is suggested but may be insufficient owing to its limited intestinal absorption and the high risk of non-compliance. High-risk patients need parenteral treatment with a recommended posology of 250 mg daily for 3 to 5 days. Intramuscular route is preferred in the outpatient setting, whereas intravenous route is suggested for inpatients. In cases where the diagnosis of WE is suspected or confirmed, a curative treatment with high-dose IV thiamine is justified. The evidence widely accepted in the literature is much clearer in this condition, with treatment regimens consisting of 500 mg IV 3 times daily for 3 to 5 days, followed by 250 mg IV daily for a minimum of 3 to 5 additional days., Conclusion: The literature does indicate that thiamine should be prescribed at high dosages, with the parenteral routes indicated in hospital settings and in high-risk patients. Based on the current literature review, we suggest treatment algorithms guiding thiamine prescription for WE., (Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS.

Introduction: Attention deficit hyperactivity disorder (ADHD) is one of the most common and challenging childhood neurobehavioral disorders. ADHD may have behavioral consequences and involvements in minor and serious crimes. Our work aims to establish links between ADHD and forensic psychiatry., Methods: A review of international scientific literature concerning the relationship between ADHD and forensic psychiatry was conducted using the PudMed electronic database. We used the Mesh terms: "attention deficit hyperactivity disorder" and "forensic psychiatry". We also used the "related articles" function of PubMed, the bibliography of selected articles and the Google Scholar database to identify possible additional papers., Results: The prevalence of ADHD in prison populations may vary but remain higher than those found in the general population. Violence committed by a person with ADHD seems to be against other persons rather than property offences. Reactive-impulsive violence seems to be more prevalent than pro-active instrumental violence. The existence of ADHD does not appear as a risk factor of recidivism. The violence risk may be increased by the occurrence of comorbidities as conduct disorders and mental deficiency. There may exist a preferential association between ADHD and antisocial personality disorder or substance abuse which both increase the risk of violence., Discussion: To put in perspective forensic psychiatry and ADHD allowed us to identify typology of violence, epidemiological aspect of ADHD in a prison environment and comorbidities involved in the risk of violence. This research permits to precise elements of prevention, diagnosis and assistance in the management of violent behaviour in ADHD and in expert practice., (Copyright © 2016 L'Encéphale, Paris.

Introduction: The progressive shifts in the legal and social contexts, along with major changes in information seeking habits with the development of the Internet, have placed patients' information at the core of medical practice. This has to be applied to the psychiatric fields as well, and to questions about how schizophrenic patients are being told their diagnosis nowadays in France., Methods: This paper is a national and international literature review about schizophrenia diagnosis disclosure practices, from 1972 to 2014, using French and English languages and various psychology and medical databases. The used key words were "diagnosis", "disclosure", "communication", "breaking bad news", "information", "schizophrenia" and "psychosis"., Results: Proportions of diagnosis announcement: our results show that the proportion of psychiatrists delivering schizophrenia diagnosis to their patients varies between countries. Although we must acknowledge that the questionnaires and samples are diverse, we have found that psychiatrists are in general less prone to deliver diagnosis information in France (from 13,5% to 39% given the studies), Germany (28%), Italy (30%), and Japan (30%), than in Anglo-Saxon countries. Thus, 70% of the psychiatrists in North America and 56% in Australia claim that they disclose their diagnosis to schizophrenic patients. In the United-Kingdom, a study targeting psychotic patients themselves has shown that 47% of them had been told their diagnosis by their doctor. Even in the countries where the proportion of diagnosis disclosure is the highest, there remains a substantial difference with other mental illnesses such as affective or anxiety disorders, which are almost always labeled as such in the information communicated to the patient (90% in North America). Diagnostic information about schizophrenia continues therefore to appear problematic for health professionals, which can seem a paradox given the recent social and legal evolutions, the therapeutic progress, the proved benefits of disclosure on compliance and therapeutic alliance, and the fact that numerous studies have shown that a majority of patients already know their diagnosis having discovered it on the Internet or by reading their treatments' notice. Reasons alleged for not disclosing diagnosis: the reasons alleged by psychiatrists for not disclosing diagnosis are various, including fear of aggravating the stigma and the emotional state of the patient, fear of giving a wrong diagnosis, fear of suicidal behavior, risk of misunderstanding, low level of patient's insight, absence of therapeutic advantage, or absence of request from the patient. Evolution of the French position about diagnosis disclosure: The publication of the relatively large study of Baylé et al. in 1999, as well as the patients' rights evolutions, has led to a debate among psychiatrists about the reasons alleged in France for not disclosing diagnosis. Among other explanations, it appeared that the theoretical reference of the psychiatrist plays a role, a psychoanalytic practice leading to increased reluctance in breaking the bad news. Thus, the psychiatrist's view of the disease, in terms of etiology and prognosis, is important as the diagnosis could become accusing if the psychiatrist believes the family environment played a role, or harmful if he has a pessimistic conception of prognosis. The question of stigma: among other reasons alleged by psychiatrists for not announcing the diagnosis, the fear of causing an increased stigma is frequently reported by professionals. In France, stigma about schizophrenia is high, not only among the general population but also among health practitioners. Even if the context has evolved during the past 30 years and the therapeutic efficiency has improved, French representations of schizophrenia remain often tinted with catastrophism and should be modified. Benefits of diagnosis disclosure: however, the benefits of disclosing diagnosis have been constantly proved in France as in other environments. Several studies have shown that patients knowing their diagnosis were likely to develop a better compliance and a stronger therapeutic alliance with their doctor. No aggravation of symptoms, suicidal risk or anxiety has been linked to the diagnosis disclosure. On the contrary, the relief of being able to put some words on symptoms, better recognize them and anticipate them, and be part of a group of patients sharing the same symptomatology has been described by patients. Furthermore, disclosing a schizophrenia diagnosis can be essential to the psychotherapeutic project, in the sense that it places the patient into an active role towards the disease and the care plan. Last but not least, the relatives can benefit from the disclosure as well and build a partnership with health professionals about medical care. Existing recommendations: in the French context, apart from individual recommendations produced by a few authors in the literature, there are no official specific recommendations about how to disclose a difficult diagnosis in the psychiatric field; only recommendations concerning severe chronic somatic disease are available. The complexity of the schizophrenia diagnosis disclosure has led some researchers - especially in North America and Australia - to adapt and use in the context of schizophrenia protocols, recommendations and even communication skills training programs that have been developed in oncology or in the field of severe chronic somatic disease., Discussion: For the situation to evolve in France, tools able to measure patients' consent - including consent to hear the bad news - ability could be used. The question of how much information and what kind of information the patients really wish should therefore be explored in deep. Also, we have seen that schizophrenia representations should be modified in the general public understanding as well as in the professional environment. Families should be more included in the reflection about diagnosis announcement, as psycho-education programs have shown their efficiency and usefulness for both patients and relatives. Finally, in order to overcome some of the difficulties related to breaking the bad news about a schizophrenia diagnosis, developing the existing Anglo-Saxon models and recommendations in France, where only very few protocols exist, could allow a positive evolution in clinical practice and help to set a therapeutic and partnering approach of diagnosis disclosure. However, in order to better understand the situation in France regarding schizophrenia diagnosis disclosure, the present state of clinical practice still remains to be analyzed precisely, as the last study on a relatively large sample was made only in 1999. Thus, the obvious limits of our study lie in the fact that most available surveys in France are not recent enough to have taken into account legal and social evolutions. Also, the studies that we used for this paper use different methodologies, in the majority focus solely on health professionals, and they are not representative enough in terms of size or sample to inform about the present state of the practice., Conclusion: As a conclusion, having stressed the lack of recent data about schizophrenia diagnosis disclosure in France, we suggest a new study using validated tools on a representative sample and taking into account both perceptions of psychiatrist and patient. As has been the case for other severe pathologies, we also suggest that a consensus conference take place on the subject of schizophrenia diagnostic information in order to elaborate guidelines to support this difficult disclosure., (Copyright © 2016 L’Encéphale, Paris.

Research on sensorial interactions with psychiatric diseases and particularly with the depressive syndrome has mainly focused on visual or auditory processes and much less on olfaction. The depressive illness is one of the most frequent psychiatric diagnoses in the community, with approximately one in five women and one in eight men experiencing a major depressive episode during their lifetime. Although genetic, epigenetic, neuroanatomical, neurochemical, neuroendocrinological and neuroimmunological changes can be detected during depression, the etiology of depression remains partly unclear. The current explanatory models are based on two main factors, i.e. pharmacological dysfunctions and stress effects. In this way and because of strong connections between olfactory pathways and cerebral areas implied in mood regulation and emotions (i.e. the limbic system and prefrontal areas), the interactions between olfaction and depression could constitute a relevant way of research at three different levels. First, olfactory dysfunction observed in depression could serve the diagnosis and contribute to a better understanding of mechanisms implied in thymic pathologies. Published papers show a decrease of olfactory sensitivity in major depression which does not occur in bipolar or saisonal depression. Second, it has been shown that olfactory deficits could induce depressive symptoms. In this context, an animal model (olfactory bulbectomized rat) reinforces the hypothesis of the important role of olfaction in depression based on neuroanatomical and neurochemical observations. Third, several publications have demonstrated that odors can positively impact the depressive mood. Thus, a remediation by odors in depression appears to be a promising way. From several decades, the olfaction/depression interactions have been covered by a broad literature. Thus, the present review will not propose an exhaustive examination but aims to point out the most recently published papers and highlight their contributions to the understanding of olfactory processes implied in depression., (Copyright © 2016 L’Encéphale, Paris.

Introduction: Attachment is a long lasting emotional link established between infants and their caregivers. The quality of early relationships allows infants to safely explore their environment and contribute to the establishment of a broad range of social skills. Several intervention programs targeting infant attachment have been implemented in different contexts, showing diverse degrees of efficacy., Objective: The present paper describes, for the first time, children's attachment quality distributions in a French multi-risk population, with a preventive intervention, usual or reinforced., Method: In the CAPEDP study (Parenting and Attachment in Early Childhood: reducing mental health disorder risks and promoting resilience), a sub-sample of 117 women was recruited to assess the effects of this home-visiting program on children's attachment security. With that intent, the Strange Situation Paradigm was used when infants were between 12 and 16 months of age., Results: In the intervention group, 63% (n=41) of the infants were coded as secure, while 15% (n=10) of them were coded as insecure-avoidant and 22% (n=14) as insecure-ambivalent/resistant. 56% (n=29) of control group infants (usual care) were coded as secure, while 27% (n=14) were coded as insecure-avoidant and 17% (n=9) as insecure-ambivalent/resistant. Even if the percentage of children with a secure attachment in the reinforced intervention group was higher than that of the control group, this difference did not reach the threshold of significance [Chi 2 (2)=2.40, P=0.30]., Discussion: Intervention group distributions were closer to normative samples, and these distributions show the clinical impact of our program. In general, preventive interventions focused on attachment quality have moderate effects but, in our case, several factors might have contributed to lower the statistical impact of the program. Firstly, the control group cannot be considered has having received zero intervention for two reasons: (a) the French usual perinatal health system (Maternal and Infant Protection System) is particularly generous and (b) the effect of this usual system might have been increased by the project intensive assessment protocol (6 visits during 28 months). Secondly, it is possible that the full effect of the intervention had not yet been detected because, when a child's attachment was assessed, only two thirds of the intervention visits had been performed (29 of 44 visits). A "sleeper effect" is still possible: we hope that a more clear result will be seen when children are assessed again, at 48 months, in our follow-up study (CAPEDP-A II). By clarifying the mechanisms involved in the development of a secure attachment, our study aims to contribute and refine the development of early preventive intervention strategies in high perinatal and psychosocial vulnerability contexts., (Copyright © 2016 L’Encéphale, Paris.

Aims: Historically, there is a strong link between depression and epilepsy. Patients with epilepsy are four to five times more likely to develop a depressive syndrome. It seems that the link between epilepsy and depression is bidirectional. There is little data on mood disorders secondary to epilepsy surgery. The goal of epilepsy surgery is to reduce the number and frequency of attacks, which in turn would allow improvements in mood disorders and cognitive impairment., Methods: A systematic search of the international literature was performed using the bibliographic search engines PubMed and Embase. The following MESH terms were used: epilepsy surgery AND (depression OR depressive disorder OR mood disorder). We also used the "related articles" of PubMed, bibliography surveys, conference abstracts and Google Scholar to identify additional relevant papers., Results: Of the 130 studies found by the systematic search, 112 are excluded because they did not take into account the mood disorders secondary to epilepsy surgery. Fifteen studies are included in this review of the literature with a case study. Depression is the psychopathological condition that is the most frequently studied. According to several studies, the prevalence of depression is approximately 30% with nearly 70% of cases diagnosed during the first three months following epilepsy surgery. The majority of patients presented depressive symptoms during the first 3 to 12months after epilepsy surgery. In these studies, the risk of developing depression is correlated with the existence of previous depressive elements relative to the epilepsy surgery. A small number of studies reported cases of de novo depression. Studies have shown a correlation between very good to excellent control of epileptic seizures and a persistent improvement of mood disorders. It would seem that depressive symptoms post-surgery are more common when the surgical intervention concerns the temporal lobe and in particular mesial resections. There are only very few cases of maniac episodes. Hamid et al. showed an increased risk of suicide waning after the epilepsy surgery over a period of 5years., Conclusion: Mood disorders are common psychiatric comorbidities in epilepsy surgery. The detection, prevention, and treatment of these symptoms in patients eligible for epilepsy surgery pose major challenges for psychiatrists and neurologists, requiring their close collaboration., (Copyright © 2016 L’Encéphale, Paris.

Introduction: Violence committed by individuals with severe mental illness has become an increasing focus of concern among clinicians, policy makers, and the general public, often as the result of tragic events. Research has shown in the past two decades an increased risk of violence among patients with mental disorder. Nevertheless, of those suffering from mental illness, perpetrators of other directed violence form a minority subgroup. The means by which there is this association between mental illness and violence has remained controversial. Factors such as positive psychotic symptoms, medication non-adherence, alcohol or psychoactive substance abuse and antisocial personality were found to be predictive of violence. Overall, literature provides support to the assertion that violent behavior of mentally ill patients is a heterogeneous phenomenon that is driven by multiple inter-related and independent factors. Furthermore, psychiatrists are often asked to predict an individual's future dangerousness, in a medical or a legal context. In the process of risk assessment of dangerousness, more focus has been placed on dynamic risk factor. In this context, lack of insight has established itself both as a part of violence risk models and as a clinical item in structured approaches to measure dangerousness. However, few studies have tested these associations. The main purpose of this paper is to review the literature concerning the relationship between insight and dangerousness and discuss the contributions of the insight in the assessment of dangerousness in patients with mental illness. We included twenty studies that evaluated the association between insight and variable such as physical or verbal violence, aggressiveness, hostility or sexual aggression., Results: According to the findings of this review, the strength and specific nature of this relationship remain unclear due to considerable methodological and conceptual shortcomings, including heterogeneity in the definition and assessment of violence, a minority of prospective studies and the lack of systematic consideration of possible confounding variables. However, the ability of the patient to perceive their illness is an important element to be considered in assessing the dangerousness both medically and legally. Higher belief flexibility and lower confidentiality of individual judgment, which reflect greater cognitive insight, may be associated with a lower incidence of violence, in particular in schizophrenia by decreasing the degree of confidence related to psychotic symptoms., Conclusion: In the growing efforts to reduce stigma associated with mental illness, it is important to identify a subgroup of patients at risk of violence and provide them with targeted treatment. In this sense, it seems important in the future to continue in this field of research to determine if the lack of insight is a covariate of a worsened condition or a specific violence risk factor per se., (Copyright © 2016 L’Encéphale, Paris.

Introduction: The aim of this paper is to underline the need for systematic monitoring of patients treated with anticholinergic antipsychotic drugs. We present the clinical history of a 34-year-old adult, treated with quetiapine in combination with other drugs with anticholinergic effects., Case Report: A 34-year-old male adult had been suffering from bipolar disorder since 2001. He was treated with risperidone, but he was not compliant due to adverse effects, including decreased libido and erectile dysfunction. On June 5th 2012, it was decided to administrate 600mg per day of quetiapine in combination with tropatepine consequent to an episode of agitation and aggressiveness. On June 14th 2012, while the patient was receiving diazepam and valproic acid, loxapine oral solution was introduced. On June 23th, the patient started mentioning digestive disorders, such as diffuse abdominal pain with constipation but continued to pass gaz. On June 25th, at 6:30 am, he declared abdominal pain, which worsened at 8:15 am despite administration of analgesics, followed by malaise and onset of vomiting. His laboratory tests showed leukocytosis 11.2G/L with neutrophils 7.7G/L. The abdomen's radiograph without preparation showed small bowel and colonic air-fluid levels. The result of the CT scan confirmed an occlusive syndrome affecting the whole small gut and colon. At 1 pm, the patient's condition worsened. He received an intramuscular injection of 100mg of loxapine and an opioid treatment, including tramadol and morphine. At 2:30 pm, the clinical condition further deteriorated with an onset of generalized abdominal contracture, the absence of abdominal breathing, sweating, tachycardia at 104 beats per minute, and hypothermia of 34.5°C. He was transferred to an intensive care unit. Laboratory tests showed metabolic acidosis, elevated liver enzymes and acute renal failure. He received volume expansion and was treated by renal replacement therapy and antibiotics. He was intubated and transferred to the operating room. At laparotomy, both colonic necrosis with perforation and necrosis of the small bowel were seen. The patient underwent total colectomy with small bowel resection, distal ileostomy and closure of the rectal stump. The onset of septic and hemorrhagic state required further surgery on June 26th. The evolution was characterized by multi-organ failure with acute anuric renal failure, multiple cardiac arrests, and systemic bacterial and fungal infection. On July 24th, this unfavorable outcome lead to death. In summary, the patient had an occlusive syndrome due to neuroleptics and complications, including mesenteric ischemia with necrotizing colitis., Discussion/conclusion: Quetiapine, like all antipsychotics, has anticholinergic effects, including cardiac, psychiatric and digestive disorders. The combination of anticholinergic drugs decreases intestinal peristalsis. Without any prompt management, this decrease can result in a colonic ischemia or necrosis. In patients treated with neuroleptics, the onset of constipation must alert medical staff. Systematic monitoring of bowel movements should be performed in any patient receiving anticholinergic drugs., (Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS.

The paper describes an action research for indicative assessment of psychological problems of young children following the 2010 earthquake in Haiti, and the interest of using the Creole version of the questionnaire PSYCa 3-6. The survey took place in Port-au-Prince, and the evaluators were trained to a proper standardized administration of the questionnaire., Background: The mental health needs of young children in natural disaster contexts often remain unaddressed. The lack of a rapid and simple tool for screening combined with few mental health professionals available to accurately diagnose and provide appropriate care mean that young children remain without care. Here, we present the results of psychological screening of young children aged 3 to 6 using the questionnaire PSYCa 3-6., Methods: This study was conducted in Port-au-Prince, Haiti. The scale was translated into Haitian Creole using corroboration of independent translations and submitted twice to the parents at home, at the end of 2011 and again at the beginning of 2013. At the first stage 166 children 3 to 6 years old were included 49 of whom were included at the second stage. The results and diagnostic properties were assessed comparing the PSYCa 3-6 to the Clinical Global Impression Severity Scale as the gold standard., Results: Boys were more prone to psychological disturbances than girls. The size and position among the siblings increased the score of psychological disturbance. The neighborhood and the perception of environmental violence had a significant impact on the score of psychological disturbance. The significant improvement in scores between the two examinations showed moderate resiliency whose main factors seemed to be the social support received by the family, the rapid return to school, faith and religious practice., (Copyright © 2016 L'Encéphale, Paris.

Introduction: This paper exposes the complexity and discrete characteristic of the adjustment disorder with reference to its clinical and scientific diagnosis. Even though the disorder occurs in frequent clinical circumstances after important life events, such as mobbing, burn-out, unemployment, divorce or separation, pregnancy denial, surgical operation or cancer, the adjustment disorder is often not considered in the diagnosis since better known disorders with similar symptoms prevail, such as major depression and anxiety disorder. Ten years ago, Bottéro had already noticed that the adjustment disorder diagnosis remained rather uncommon with reference to patients he was working with while Langlois assimilated this disorder with an invisible diagnosis., Methodology: In order to maximize the data collection, we used the article review below and challenged their surveys and results: National Center for Biotechnology Information (NBCI - Pubmed) for international articles and Cairn.info for French literature. Moreover, we targeted the following keywords on the search engine and used articles, which had been published from 1 February 1975 to 31 January 2015: "adjustment", "adjustment disorder" and the French translation "trouble de l'adaptation"., Results: One hundred and ninety-one articles matched our search criteria. However, after a closer analysis, solely 105 articles were selected as being of interest. Many articles were excluded since they were related to non-psychiatric fields induced by the term "adaptation". Indeed, the number of corresponding articles found for the adjustment disorder literally pointed-out the lack of existing literature on that topic in comparison to more known disorders such as anxiety disorder (2661 articles) or major depression (5481 articles). This represents up to 50 times more articles in comparison to the number of articles we found on adjustment disorder and up to 20 times more articles for the eating disorder (1994), although the prevalence is not significantly higher than for the adjustment disorder. According to their relevance and their content, we have split the articles into seven subcategories: 1. General description: most scientific articles generally describe the adjustment disorder as being a transition diagnosis, which is ambiguous, marginal and difficult to detect. The findings claim that only a few studies have been conducted on the adjustment disorder despite a high prevalence in the general population and in the clinical field. 2., Classification: the DSM-5 defined the adjustment disorder as a set of different outcomes and syndromes induced by stress after a difficult life event. While the link to other disorders has not been mentioned, the diagnosis of this disorder is no longer excluded or perceived as a secondary diagnosis. The DSM-5 faced criticism from three points of view: the operationalization of the concept of stress, the differential diagnosis and the description. 3. Prevalence: different samples have shown a significantly high prevalence of the adjustment disorder within the population. In addition to the psychiatric pain induced by difficult life events we need to emphasize the fact that 12.5 to 19.4 percent of the patients faced heavy and severe pathologies and depended on clinical care and treatment. 4. Etiology, comorbidity or associated symptomatology: the literature identified the tendency to commit suicide and stressful life events as being two fundamental characteristics of adjustment disorder. The third one is the personality profile. 5., Differential Diagnosis: that motivates researchers to focus on the adjustment disorder: the differentiation approach as to the major depression. Indeed, the aetiology, the symptomatology and the treatment differ from the adjustment disorder. 6., Assessment: very recently, Dutch researchers have developed and validated the Diagnostic Interview Adjustment Disorder (DIAD). 7., Treatment: in 2014, no data or meta-analysis recommended drug treatment in addition to therapy. In fact, several authors have demonstrated the ineffectiveness of drug therapy. The literature suggests a psychotherapeutic approach to treat adjustment disorder., Conclusion: Emotional reactions triggered by life events are responsible for full therapy agendas and for the rush in emergency rooms and hospitals. The reflex when faced with crying, insomnia or suicidal thoughts to give a diagnostic of major depressive disorder s is generally accepted by everyone. The elevated risk to commit suicide and the approved success of remission or healing through treatment (psychotherapy) are two major reasons why several studies promote the importance and the need to identify the adjustment disorder of our patients., (Copyright © 2016 L'Encéphale, Paris.

In this paper, we report the case of a patient, aged 26, with schizophrenia who was admitted to psychiatric emergencies for catatonia, one week after abrupt discontinuation of clozapine. An improvement was seen after only two days of the reintroduction of clozapine alone. This catatonia is reversible and it responds magnificently to the reintroduction of clozapine. And we conclude that patients and their caregivers need to be educated about the effects of abrupt cessation of clozapine administration., (Copyright © 2016 L’Encéphale, Paris.

Introduction: Forensic psychiatry is the field whose expertise is the assessment and treatment of offending behaviours, in particular when offenses are related to mental illness. An underlying question for all etiological models concerns the manner in which an individual's behaviours are organized. Specifically, it becomes crucial to understand how certain individuals come to display maladaptive behaviours in a given environment, especially when considering issues such as offenders' responsibility and their ability to change their behaviours., Virtual Reality: Thanks to its ability to generate specific environments, associated with a high experimental control on generated simulations, virtual reality is gaining recognition in forensic psychiatry. Virtual reality has generated promising research data and may turn out to be a remarkable clinical tool in the near future. While research has increased, a conceptual work about its theoretical underpinnings is still lacking. However, no important benefit should be expected from the introduction of a new tool (as innovative as virtual reality) without an explicit and heuristic theoretical framework capable of clarifying its benefits in forensic psychiatry., Objectives: Our paper introduces self-regulation perspective as the most suitable theoretical framework for virtual reality in forensic psychiatry. It will be argued that virtual reality does not solely help to increase ecological validity. However, it does allow one to grant access to an improved understanding of violent offending behaviours by probing into the underlying mechanisms involved in the self-regulation of behaviours in a dynamical environment. Illustrations are given as well as a discussion regarding perspectives in the use of virtual reality in forensic psychiatry., (Copyright © 2015 L’Encéphale, Paris. Published by Elsevier Masson SAS.

Context: The growing field of new technologies offers new ways to tackle psychiatric disorders (e.g. virtual reality therapy, neurofeedback, etc.). Serious games (SG) are computer applications combining serious aspects with the fun side of video games. This kind of new media could find applications to treat psychiatric disorders., Objective: This paper summarizes available data in the literature about therapeutic interventions using SG in psychiatry., Method: A Medline search was conducted in May 2014 using the following Medical Subject Headings (MESH) terms: "video games", "mental disorders", and "psychotherapy"., Results: Only 10 relevant references were identified according to our inclusion criteria. These studies show that SG are very interesting tools to improve the management of psychiatric disorders. However, only low-level evidence is available to support treatment with SG in patients suffering from psychiatric disorders. Indeed, randomized controlled trials are rare in this field of research., Conclusion: SG provide promising therapeutic innovations for the management of psychiatric disorders. Moreover, they could easily be developed in accordance with current dimensional approaches. Finally, major issues to facilitate the implementation of future work on SG in psychiatry are discussed., (Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.)
