International audience; The psychological effects of isolation have already been described in the literature (polar expeditions, submarines, prison). Nevertheless, the scale of confinement implemented during the COVID-19 pandemic is unprecedented. In addition to reviewing the published studies, we need to anticipate the psychological problems that could arise during or at a distance from confinement. We have gone beyond the COVID-19 literature in order to examine the implications of the known consequences of confinement, like boredom, social isolation, stress, or sleep deprivation. Anxiety, post-traumatic stress disorder, depression, suicidal or addictive behaviours, domestic violence are described effects of confinement, but the mechanisms of emergence of these disorders and their interrelationships remain to be studied. For example, what are the mechanisms of emergence of post-traumatic stress disorders in the context of confinement? We also remind the reader of points of vigilance to be kept in mind with regard to eating disorders and hallucinations. Hallucinations are curiously ignored in the literature on confinement, whereas a vast literature links social isolation and hallucinations. Due to the broad psychopathological consequences, we have to look for these various symptoms to manage them. We quickly summarize the diagnostic and therapeutic approaches already in place, such as telemedicine, which is undergoing rapid development during the COVID-19 crisis.

It is widely acknowledged that adolescents and young adults are particularly vulnerable to suicidal behavior. However, the “service desert”—the persistent lack of access to care services—within this population remains a major obstacle to prevention. Although it has brought with it specific risks, the ubiquity of social media offers new ways of overcoming the traditional barriers to help-seeking, owing to the specific modes of interaction and communication that it involves. The Elios project (Équipe en ligne d’intervention et d’orientation pour la prévention du suicide/Online Intervention and Referral Team for Suicide Prevention) aims to harness the digital possibilities of social media to promote access to care for suicidal young people. It consists of a team of online clinicians who will provide suicidal young people with first-line assistance by intervening directly on social media platforms thanks to innovative and integrated technological solutions. Specifically, Elios will offer online counseling, motivational support, crisis intervention, and referral to mainstream care services. The system is due to be implemented as part of a randomized controlled trial. If proved effective, it could be used for other care situations within France’s conventional health care system., Bien que la vulnérabilité particulière des adolescents et des jeunes adultes aux conduites suicidaires soit largement établie, le défaut persistant d’accès aux soins dans cette population reste un obstacle majeur à la prévention. Sans être dénués de risques propres, les réseaux sociaux, dont l’utilisation s’est largement généralisée, offrent des modalités d’interaction et de communication qui pourraient permettre de dépasser les classiques obstacles à la recherche d’aide. Le projet d’Équipe en ligne d’intervention et d’orientation pour la prévention du suicide (Elios) vise à exploiter les potentialités du numérique pour favoriser l’accès aux soins chez les jeunes suicidaires. Il consiste en une équipe de web-cliniciens qui interviendront directement sur les réseaux sociaux, en utilisant des solutions technologiques innovantes et intégrées, pour apporter aux jeunes une première réponse, soutenir leur démarche de demande d’aide, les sécuriser lorsque nécessaire et les orienter vers des services de soins conventionnels. Actuellement mis en œuvre et évalué dans le cadre d’un essai contrôlé randomisé, le dispositif pourrait être généralisé comme une offre de soins de droit commun.

International audience; BackgroundAttempted suicide is a major risk factor of further re-attempts and death. Self-harm behaviors are related to multiple causes explaining why it is ineffective to have a single and simple strategy to offer after the clinical assessment in reducing morbidity and mortality. Furthermore, treatment adherence is known to be especially poor in a context where social connection seems compromised and a source of pain. Effective interventions can be divided into two categories: intensive intervention programs (care at home, supported by a series of brief psychotherapy interventions) and case management programs that rely on a “stay in contact” dimension. These programs, initiated by Jerome Motto and its short letters may consist of: (1) sending letters or postcards after discharge of the ER; (2) giving a crisis card that offers a crisis telephone line and a crisis unit for hospitalization if needed, and; (3) placing a phone call at some time distance after the discharge. The aim is to enhance a “connectedness feeling” with the patient. These different strategies have proven to be even more effective in some specific subgroups, highlighting the heterogeneity of this population. Each modality of contact was well accepted and generated a positive involvement of the patients.MethodIt led to the idea of combining these different strategies in an algorithm built on the specificity of identified subgroups. A randomized controlled trial, named ALGOS was carried out in France to test this algorithm in 2011. The algorithm consisted of: (1) delivering a crisis card for first attempters; (2) giving a phone call for re-attempters to re-assess their situation between the 10th and 21st day after their discharge, and to propose a new intervention if needed, and; (3) in case of an unsuccessful call or a refusal of proposed care, sending personalized postcards for 6 months. All of this was supported with shared information to the general practitioner of the patient. This study was further adapted to routine care in 2015 in the northern departments of France, Nord and Pas-de-Calais (4.3 million people), taking the name of VigilanS. The inclusion consists of sending a form for every patient assessed after a suicide attempt in the two departments to the medical staff of VigilanS in order to provide information about the patient and the context of his suicide attempt. The algorithm has been modified in giving the crisis card to all the patients whether it is a first attempt or not. An information letter, explaining the aim of the monitoring is also given to the patient, and to his general practitioner. The calling staff is composed of 4 nurses and 4 psychologists, all trained in suicidal crisis management. They use a phone platform located in the Emergency Medical Assistance Service (SAMU) of the Nord department on a halftime basis and manage the incoming calls from the patients as well as the outgoing calls towards the patients, their relatives and their medical contacts. A set of 4 postcards (1 per month) can be sent if needed in case of an inconclusive or a failed phone call.ConclusionBuilt on a monitoring philosophy, VigilanS has further developed a real crisis case management dimension requiring enough time to insure an effective medical supervision and strong networking abilities. A specific time is also needed to take care of all the technical aspects of the organization. This program expertise, designed by Northern departments to prevent suicide, can be shared with other French or even foreign territories.; Les tentatives de suicide constituent un facteur de risque majeur de récidives et de décès. Les comportements suicidaires sont polyfactoriels et rendent inefficace une stratégie unique de prévention. L’adhésion aux soins est mauvaise dans un contexte où les liens sociaux sont souvent en souffrance. Deux catégories de programmes ont montré leur efficacité : les dispositifs d’intervention intensive et les dispositifs de veille. Ces derniers peuvent recouvrir différentes modalités : envois de courriers, remise de carte de crise comportant un numéro d’urgence, rappels téléphoniques. Un essai contrôlé randomisé, ALGOS, a combiné ces différentes stratégies dans l’algorithme suivant : délivrance d’une carte de crise pour les primosuicidants ; rappel téléphonique des non-primosuicidants 15jours après leur sortie des urgences ; envoi de cartes postales personnalisées mensuellement pendant 6 mois en cas d’échec de l’appel ; information du médecin traitant. Cette étude a été adaptée en soins courants en 2015 dans les départements du Nord et du Pas-de-Calais sous le nom de VigilanS. L’algorithme a été légèrement modifié par la remise de la carte de crise à tous. L’équipe de recontact, formée à la gestion de crise, gère tous les appels sortants et entrants vers les patients, leurs proches et leurs soignants. Un jeu de 4 cartes postales peut être envoyé en cas d’appel téléphonique non concluant. S’appuyant sur une philosophie de veille, VigilanS a développé un véritable savoir-faire de gestion de crise, nécessitant une supervision médicale constante et de solides capacités de mise en réseau.

Major depression represents among the most frequent psychiatric disorders in the general population with an estimated lifetime prevalence of 16-17%. It is characterized by high levels of comorbidities with other psychiatric conditions or somatic diseases as well as a recurrent or chronic course in 50 to 80% of the cases leading to negative repercussions on the daily functioning, with an impaired quality of life, and to severe direct/indirect costs. Large cohort studies have supported that failure of a first-line antidepressant treatment is observed in more than 60% of patients. In this case, several treatment strategies have been proposed by classical evidence-based guidelines from internationally recognized scientific societies, referring primarily on: I) the switch to another antidepressant of the same or different class; II) the combination with another antidepressant of complementary pharmacological profile; III) the addition of a wide range of pharmacological agents intending to potentiate the therapeutic effects of the ongoing antidepressant medication; IV) the association with appropriate psychological therapies; and, V) the use of non-invasive brain stimulation techniques. However, although based on the most recently available data and rigorous methodology, standard guidelines have the significant disadvantage of not covering a large variety of clinical conditions, while currently observed in everyday clinical practice. From these considerations, formalized recommendations by a large panel of French experts in the management of depressed patients have been developed under the shared sponsorship of the French Association of Biological Psychiatry and Neuropsychopharmacology (AFPBN) and the Fondation FondaMental. These French recommendations are presented in this special issue in order to provide relevant information about the treatment choices to make, depending particularly on the clinical response to previous treatment lines or the complexity of clinical situations (clinical features, specific populations, psychiatric comorbidities, etc.). Thus, the present approach will be especially helpful for the clinicians enabling to substantially facilitate and guide their clinical decision when confronted to difficult-to-treat forms of major depression in the daily clinical practice. This will be expected to significantly improve the poor prognosis of the treatment-resistant depression thereby lowering the clinical, functional and costly impact owing directly to the disease.

International audience; IntroductionThe literature data show that relaxation practice is effective in reducing anxiety symptoms. Different techniques such as progressive muscular relaxation, autogenic training, applied relaxation and meditation have been evaluated independently for anxiety disorders. The question is to know whether the combination of various techniques may be of interest in the transdiagnostic treatment of anxiety disorders.Aim of the studyThe present study assessed the short-term efficacy of a 10-week integrative and transdiagnostic relaxation program for anxiety disorders in outpatients of an anxiety disorders unit.MethodsThe diagnoses were made according to the Mini-International Neuropsychiatric Interview (MINI; Sheehan et al., 1998) and completed with an assessment of anxiety and depressive symptoms using: the State Trait Anxiety Inventory (STAI-Y, -S and -T), the Penn State Worry Questionnaire (PSWQ) and the Beck Depression Inventory (BDI-II). Four techniques were integrated into the structured 10-week protocol: breathing control, muscular relaxation, meditation and mental visualization.ResultsTwenty-eight patients (12 men and 16 women), mean age (S.D.)=38.82 years (11.57), were included in the study. All the included patients fulfilled the DSM-IV criteria for a current diagnosis of Generalized Anxiety Disorder (n =13) or Panic Disorder (n =15) with or without agoraphobia. At the end of the 10 sessions, we found a significant reduction in mean scores (S.D.) on the STAI-T from 53.179 (6.037) to 49.821 (8.028) (P

International audience; Of all the psychological complications that an individual is likely to present with when confronted with an exceptional event, the Post-Traumatic Stress Disorder is characterized by being progressive, frequent, invalidating, strongly associated with comorbidity, and having the tendency to become chronic if it is not detected clinically. By definition, it is threatening and produces an intense fear reaction. The traumatic event is a situation of extreme stress, not only capable of altering the physical and psychological homeostasis of the individual, but is also recognized as determinant in the aetiopathology of complications. The intensity of this distress can be identified clinically and physiologically, and is currently considered as an important risk factor for the development of PTSD later on, together with other pre-, peri- and post-traumatic factors. In fact, the most studied field is the therapeutic approach, in particular drug treatment, of the fully-constituted disorder, although this actually represents tertiary prevention. Even though primary prevention seems to concern Medicine very little, any prospect of performing secondary prevention should begin by rapid identification of the risk or vulnerability factors and should allow a population at risk from developing complications to be defined. Its potential therapeutic impact brings together psychotherapeutic and drug treatment, since it is only this combination that seems able to allow the most favourable clinical outcome to be achieved for an individual, who is confronted by an out-of-the-ordinary event. The aims of secondary prevention strategies are, for example, to reduce the incidence of acute PTSD in patients seen following the event. The benefits for the individual and for the society can easily be measured in terms of the consequences on his/her social, professional and family life, or in terms of cost. The usefulness of this prevention can also be measured by the possible ways that other conditions, comorbid to PTSD, are controlled, such as anxiety disorders, depression and substance abuse, for example. Secondary prevention strategies may also be aimed at determining the therapeutic impact, by preventing or moderating the appearance of an acute stress, or even by contributing in avoiding the onset of chronic PTSD. Psychopharmacology of the immediate and post-immediate disorders, however, remains a field which has been studied very little. Reduction or control of the high, prolonged level of hyperarousal phenomena or hypersensitization of the hypothalamo-pituitary axis, would contribute to the comfort of the individual, and would participate in the prevention of PTSD. Based on current knowledge of the neurobiology of trauma, we look into the existing and potential pharmacological possibilities. Even though benzodiazepines tend to have an important role, knowledge of other drugs and therapeutic groups is rapidly increasing. In this review, we will see that the efficacy of anti-adrenergic drugs and certain other anxiolytics is now well-documented, this opening the door to their use in the future. Other drug groups offer interesting, well-proven approaches, such as serotoninergic drugs, CRF or NPY antagonists, NMDA antagonists, anticonvulsants or other GABAergic agents. In view of this disorder, which represents a true public health problem, we consider that it is now possible to widen the horizons of our drug therapy, in combination with any necessary psychotherapeutic treatment, to reach the heart of the traumatic event, that often upsets the victims, both by the psychological suffering it induces, and the loss of his/her social, family and professional references and support structures.

International audience; INTRODUCTION: There is a wide range of non-specific symptoms that can reveal neurolupus, sometimes making diagnosis difficult. OBSERVATION: A 29-year-old man presented, from 1996 to 2002, three episodes of mood disorders with hetero-aggression, preceded by seizures, which resolved completely. Repeated investigations were negative except for lymphopenia, an inflammatory cerebrospinal fluid and some rare non-specific areas of high intensity signals in the white matter on the brain MRI. After a six-year course, the patient was considered to have a severe mood disorder related to a schizoid personality. A new dot-blot search for antinuclear antibodies detected anti-Sm antibodies was positive, leading to the diagnosis of neuropsychiatric lupus since the patient's symptoms fulfilling four of the American Rheumatism Association criteria (neuropsychiatric events, lymphopenia, antinuclear and anti-Sm antibodies). The patient was given monthly pulses of cyclophosphamide and remained symptom free one year after the last flare up. CONCLUSIONS: Lupus can rarely be revealed by long-standing isolated psychiatric disorders. Search for auto-antibodies, using highly specialized techniques (western blot, dot blot) should be a routine practice since antibody titres fluctuate during the course of the disease; elevated titres may correlate with exacerbations. Considering the prominence and severity of these behavior disorders, systemic diseases may often be misdiagnosed.

International audience; The Psychiatry department of the University Hospital Centre of Lille has developed, over the last 10 years, a treatment network for psychiatric disorders during pregnancy or in the post-partum period. There are liaison consultations in the maternity department, screening and management of psychopathological disorders in the perinatal period, training of midwives, support of patients seeking genetic counselling, collaboration with teams providing "medically-assisted procreation", etc. For severe disorders of the post-partum period (severe depression, serious alteration of mother-child interaction, puerperal psychosis), the Psychiatry department has a specialized unit where 3 "mother-child" groups can be admitted. This unit is particularly effective if the patients and their family understand this healthcare system and stick to it to a certain extent. Even if improvements are always possible, cases in which situations occur as an emergency, are when dysfunctions are most frequently seen. On 7th December 1998, a Crisis Intervention Unit (CIU) was created with 15 short-term beds, for stays up to 72 hours. The CIU was opened in the Psychiatry department, close to the main Accident and Emergency department, with 2 aims: firstly to provide a setting and resources for a number of emergency psychiatric situations, and secondly to provide a place and time for crisis situations which we admit to the unit, with a view to facilitating interaction and to propose in certain cases a process of crisis intervention, which later continues on an outpatient basis. After being open for a year, the CIU has proved to be an improvement to all of the healthcare services which are available. It should be noted that the situations which need highly specialized resources in such a short time, are those which cause the most acute problems. This is at times when the emergency services network, with its internal logic, require another network based on a different logic, that the interface problems are at their most acute. The situations reported here, which require a fluid interface between the emergency services and the "mother-child" networks, are examples. We report 3 clinical situations, which illustrate 3 possibilities of action: the first, in which 2 successive stays in the CIU allowed an admission to the "mother-child" unit in satisfactory conditions, the second, in which overall management was based on hospitalization in the Obstetrics department and several visits to our Unit, and the last one, in which the whole medico-psycho-social approach was set up after a single stay of 3 days. Since the opening of Crisis Intervention Unit, around 1,000 patients have been treated there; 37 were women with difficulties with their pregnancy, 17 of whom required direct intervention by the "mother-child" team. The contexts were: 5 prenatal depressions, 4 post-partum depressions, 3 cases of hyperemesis gravidarum, 5 rejections of pregnancy and/or situations at risk of infanticide. The almost constant suicidal risk should be noted, or even attempted suicide, at the time of admission to the CIU. The other 20 women had psychopathological disorders linked to sterility, medically-assisted pregnancy, termination of pregnancy or pregnancy in women suffering from long-term somatic illnesses (insulin-dependent diabetes, lupus, etc.). When a psychopathological episode occurs during pregnancy, it is essential to preserve the developing relationship with the child in an intermediate place, in a healthcare perspective and to prevent any future impairment of the quality of the mother-child relationship by the psychiatric disorder. The Crisis Intervention Unit is not an emergency "mother-child" unit. Other French experiences have been reported, an example being mother-baby hospitalization in a crisis centre. The aim of our interventions is not the same, and our local context, together with the availability of a healthcare network on different floors, which is specific and close-by, allows this approach. Also, the contribution of Liaison Psychiatry in emergency situations should not be minimized. It is necessary to work in collaboration with the obstetricians. In fact, the chance to work with us was given by asking for a hospitalization in the Obstetric unit, during the prepartum period of pregnancies with a psychiatric risk. This way of proceeding allows somatic monitoring in hospital to be performed, whenever the risk run by the mother and/or the child requires it. This "analogue" procedure, however preventative it may be, does not always allow specific treatment of the psychiatric disorders to be given, despite liaison psychiatry interventions. Our interventions are not a specialized "mother-child" unit, or a substitute for Liaison Psychiatry, but they are specifically aimed at the context of the crisis. Obviously, it is precisely this dimension of the crisis which makes the other types of management temporarily unsuitable. This new working framework, with the simple possibility of admitting women and interacting with them in a crisis situation, with the aid of the competence of "mother-child" teams, most often seems to allow an alternative to hospitalization in the Psychiatry department, at the same time keeping up quality management of problems linked to the pregnancy or post-partum period. The specificity of the CIU, with its project of taking the special psychiatric vulnerability of pregnancy into account, makes sure that the psychopathological aspects of the crisis situation and the physiological aspects of adaptation reactions to the perinatal period are not neglected, but that are respected by this type of interaction/intervention.

International audience; Although they are likely to add their effects, physical and psychic traumata (or traumas) can provoke in different ways the appearance of depressive symptoms sometimes common. Post-traumatic depression, reactional depression, major depressive disorder and post-traumatic stress disorder represent different clinical and nosographic disorders in despite of their occasionally common symptomatic core. Historically, it is interesting to note during the XXth century the true semantic change of the terms of trauma from the somatic field to the psychic sphere. Physical traumatism is often represented by a material shock for the subject and by its organic consequences. It is defined as an event that leaves its mark which itself inflicts and handicaps the vital trajectory of the subject. It primarily comprises brain and rachis injuries, whose evolution is frequently characterized by the occurrence/appearance of a depressive disorder, whose genesis rests on psychological but also neurobiologic and physical arguments. Thus major depressive disorders are often present in the course of various physical traumatisms mainly related to nervous system. In accordance with several studies, the prevalence of major depressive disorders ranges from 25% to 50%. These mood disorders occur in the year which follows the accidental event. Their average time of revelation is estimated at four months and their average duration lies between three and six months. Lastly, although these depressive illnesses present clinical symptoms comparable with those observed in other contexts, some nuances can be raised. Nonetheless, they confine sometimes with true clinical forms depending on the intensity, the form, the circumstances or the consequences of the trauma. Psychic traumatism doesn't have the same profile and rests for much dedicated with the reexperiencing. Thus for some authors, depression illness represents a disorder that occurs after a traumatic event whereas others see a differential diagnosis which exludes or which represents a comorbidity with post-traumatic stress disorder. The review of the literature allows us to emphasize the complexity of the links as well as the clinical and epidemiologic differences between stress disorder and major depressive disorder. From the clinical point of view, the major features of PTSD are articulated around a triad of symptoms. They include the reexperiencing symptoms of the traumatic event such as intrusive memories and recurrent nightmares, the protective reactions such as avoidance of the stimuli associated with the trauma and emotional numbing, and the arousal symptoms such as the startled response and hypervigilance. The complexity of this syndrom is due to the frequent combination of these symptoms with other nonspecific ones. As far as the mood is concerned (the mood symptoms are concerned), the regrouping of some of these symptoms allows the clinician to sometimes releave a depressive symptomatology without being able to assess the DSM diagnosis of major depressive disorder. Epidemiologic studies dealing with the risk of installation of a PTSD after a traumatic event reveal differences in the prevalence depending on the nature of the traumatic events: ranging from 1% in general population to 80% following some situations of extreme and durable psychic suffering. Between both poles, one finds a prevalence ranging between 20 and 50% following other events such as serious accidents, natural disasters or criminal assaults. The clinical features of depressive episodes comorbid or associated with PTSD have some characteristics making it possible to individualize various clinical forms as a function of traumatic event type: asthenic, characterial or with somatic symptoms. According to the majority of authors, the co-occurrence of post-traumatic stress disorder and major depressive disorder is high although differential diagnosis is sometimes difficult. However, conceptual differences remain and two conceptions are distinguished. For some authors, like Bleich and Shalev, there would not be true chronological evolution from PTSD to MDD. Moreover the presence of symptoms considered as pertaining to the mood register within the criteria of PTSD would be clearly predictive of the occurrence and the severity of the diagnosis but not of the chronicity. For others, there would be a continuity between post-traumatic stress disorder and major depressive disorder. It is the case in many studies of veterans but also for civilian traumatic events. It is also the case for the American national study of comorbidity in which Kessler concludes that for 78% of the subjects who present a comorbidity PTSD/MDD (comorbidity raised for 48% of the 5,877 subjects included), the mood disorder is secondary to PTSD. (ABSTRACT TRUNCATED)

International audience; Neuroleptics are the main biological treatment for psychotic patients. The brutal withdrawal of a neuroleptic treatment may induce an important aggravation of the psychotic symptoms. A few of those relapses may occur very early after the interruption of treatment; they are often associated with a modification of the symptoms and an unfavorable evolution in the course of the illness. Using those clinical observations a few authors have developed the concept of supersensitivity psychosis to explain those kinds of relapses and to formulate hypothesis about tolerance and resistance to neuroleptics. They focus on the possible correlation between supersensitivity psychosis and tardive dyskinesia. We report three cases of a dramatic aggravation of the psychotic symptomatology following the withdrawal of clozapine in three schizophrenic patients resistant to classical neuroleptic treatment. According to the clinical data and to the physiopathological hypothesis, the concept of supersensitivity psychosis can have implications in the therapeutic management of resistant schizophrenic patients.

International audience; According to the literature, electroconvulsive therapy and benzodiazepines, especially lorazepam, are recommended for the treatment of catatonia. We report the case of a 56-year-old woman with catatonia resistant to electroconvulsive therapy and benzodiazepines. Treatment with zolpidem led to durable improvement. This case suggests that zolpidem should be tested in catatonia since side effects are minimal.

International audience; Dysregulation of free radical metabolism has been supposed to be involved in schizophrenia etiopathogeny. Recently, Wang et al. showed a red blood cell super oxide dismutase increase in positive schizophrenia (Crow's type I), but neither in negative schizophrenia (Crow's type II) nor in controls. The study included 28 in-patients suffering from acute positive psychosis who were compared with 15 controls. We confirmed the results of Wang. We found a significantly red blood cell Super oxide dismutase increase in positive psychosis, in comparison to negative psychosis and controls (p = 0.0001). This SOD increase was in relationship with the degree of clinical psychomotor excitement. After 21 days of neuroleptic treatment, SOD activity decreased and reached standard values. These results support the hypothesis of striking relationships between catecholaminergic hyper-metabolism and SOD increase, in positive psychosis. These could account for psychotic positive symptoms improvement with neuroleptic treatment, which blocks dopamine pathways.

International audience; Serum levels of haloperidol and reduced haloperidol as well as the reduced haloperidol/haloperidol ratios were determined in nine acute schizophrenics on oral haloperidol medication and correlated over 21 days with psycho pathology and extra-pyramidal symptom scores. We have investigated red blood cells haloperidol reductase activity in the group of patients. Significant correlations were found between haloperidol plasma levels and positive sub scale for each patient (r = 0.86 and p < 0.01; r = 0.70 and p < 0.05). We found a correlation between red blood cells reductase activity and the improvement of the psychotic anxiety scale (r = 0.64/and p < 0.05; r = 0.67 and p < 0.05), but not with reduced haloperidol/haloperidol ratios in plasma. The knowledge of reductase activity could predict the treatment response in acute schizophrenic patients. We suggest that the reported inter individual and inter ethnic differences in haloperidol and reduced haloperidol and in clinical response and adverse effects may be a reflection of genetic control of the two oxidative pathways mediated by cytochrome P450 isozyme and/or the reductase pathway mediated by haloperidol reductase in individual subject.

International audience; A 62 year-old man presented with melancholia with delusions, possibly resulting from lenticular lesion in the left and frontal damages in the right. Atypical signs of our observation led us to consider our patient not as suffering of affective disorder. We suggest that melancholia could be a consequence of a certain type of stereotyped mental activity, and we would compare this stereotyped mental activity to mental compulsive activity described in "loss of psychic self activation" of D. Laplane. In this perspective our observation would be a variant of "Loss of psychic self-activation". Heuristic value of this concept is discussed.

International audience; A 72 years-old man presented with melancholia with delusions, possibly resulting from multiple lacunar infarcts in the basal ganglia. This case is akin to the syndrome of psychic akinesia and compulsive activity, resulting from lenticular nucleus lesions or frontal lobe lesions. We suggest that melancholia could be a consequence of a certain type of stereotyped mental activity and we would compare this stereotyped mental activity to stereotyped verbal activity in aphasia. Cognitive impairment might then be a cause of depression.
