Introduction: Attention deficit hyperactivity disorder (ADHD) in adults could be frequently underdiagnosed due to concomitant psychiatric disorders, including depressive symptomatology, which could determine inappropriate treatments. Our study aims at clinically characterizing adult ADHD with or without depressive symptomatology in order to identify the relationship with specific affective temperamental profiles and coping strategies., Methods: A total of 225 outpatients consecutively afferent to our outpatient adult ADHD service since September 2019 were retrospectively screened for eligibility and administered Beck Depression Inventory-II (BDI-II), Coping Orientation to Problems Experienced Inventory (COPE-NV) and Temperament Evaluation of the Memphis, Pisa, Paris and San Diego (TEMPS-M)., Results: 64.7 % of patients displayed a significant comorbid depressive symptomatology. According to the multivariate linear regression model, depressive levels were positively predicted by TEMPS-M cyclothymic subscale (B = 0.567, p = 0.004) and negatively predicted by COPE-NVI "positive attitude" subscale (B = -0.438, p = 0.024) (R = 0.496, R 2  = 0.246, F(2,66) = 10.747, p < 0.001)., Limitation: While considering the results, it should be taken in consideration that: the assessment was carried out only at baseline, our sample is constituted only by adult ADHD patients and mostly without a previous ADHD diagnosis, the presence of a discrepancy between the rates of ADHD subtypes, the absence of a healthy control group and emotional dysregulation was not directly assessed., Conclusion: Affective temperamental profiles and coping strategies could help in clinically characterizing and personalizing treatment in adult comorbid ADHD-depressive symptomatology patients. Further research is warranted to explore the efficacy of targeted psychotherapeutic and pharmacological interventions within this ADHD sub-sample., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Abstract: Adult attention-deficit disorder (ADD) is a common diagnosis, and amphetamine medications are increasingly used. Recent reports suggest high prevalence of affective temperaments, such as cyclothymia, in adult ADD. This study reexamines prevalence rates as reflecting misdiagnosis and reports for the first time on the effects of amphetamine medications on mood/anxiety and cognition in relation to affective temperaments. Among outpatients treated at the Tufts Medical Center Mood Disorders Program (2008-2017), 87 cases treated with amphetamines were identified, versus 163 non-amphetamine-treated control subjects. Using the Temperament Scale of Memphis, Pisa, Paris and San Diego-Autoquestionnaire, 62% had an affective temperament, most commonly cyclothymia (42%). In amphetamine-treated cases, mood/anxiety symptoms worsened notably in 27% ( vs. 4% in the control group, risk ratio [RR] 6.2, confidence interval [CI], 2.8-13.8), whereas 24% had moderate improvement in cognition ( vs. 6% in the control group; RR, 3.93; CI, 1.9-8.0). Affective temperaments, especially cyclothymia, are present in persons about one-half of persons diagnosed with adult ADD and/or treated with amphetamines., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background and Objectives : Emotional dysregulation is central to the problem of the overlap between attention-deficit/hyperactivity disorder (ADHD) and cyclothymia. The aim of the study was to evaluate comorbidity rates between ADHD and cyclothymic disorder and to explore demographic and clinical differences among the groups, focusing on affective temperament and emotional dysregulation. Materials and Methods : One hundred sixty-five outpatients attending the Second Psychiatry Unit at the Santa Chiara University Hospital (Pisa) were consecutively recruited: 80 were diagnosed with ADHD, 60 with cyclothymic disorder, and 25 with both conditions. Temperament Evaluation of Memphis, Pisa, Paris, and San Diego (TEMPS-M) and the 40-item version of Reactivity, Intensity, Polarity, and Stability questionnaire (RI-PoSt-40) were administered. Results : Cyclothymic patients were more frequently female and older with respect to the ADHD groups. Both comorbid and non-comorbid ADHD patients showed significantly lower educational attainment and more frequently had substance use disorders. Panic disorder was common in non-comorbid cyclothymic patients, who showed significantly higher rates of familial panic disorder, major depressive disorder and suicide attempts in comparison with patients only diagnosed with ADHD. Cyclothymic patients without ADHD were also characterized by fewer hyperthymic temperamental traits, higher depressive and anxious dispositions, and a greater negative emotionality. No significant differences among groups were observed for cyclothymic temperament and overall negative emotional dysregulation, but comorbid patients with both conditions scored the highest in these subscales. This group also showed significantly higher affective instability with respect to ADHD patients without cyclothymia and was less frequently diagnosed with bipolar disorder type II than patients from both the other groups. Conclusions : ADHD and cyclothymia often co-occur and show similar levels of emotional dysregulation. However, cyclothymic patients may be more prone to negative emotionality in clinical settings. Subjects with "sunny" cyclothymic features might escape the attention of clinicians unless ADHD is present.

Background and Objectives: The role of affective temperament in the genesis and outcome of major mood disorders is well studied, but there are only a few reports on the relationship between panic disorder (PD) and affective temperaments. Accordingly, we aimed to study the distribution of affective temperaments (depressive (DE); cyclothymic (CT); irritable (IRR); hyperthymic (HT) and anxious (ANX)) among outpatients with PD. Materials and Methods: Affective temperaments of 118 PD outpatients (80 females and 38 males) with or without agoraphobia but without any other psychiatric disorder at the time of inclusion were evaluated using the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) and compared with the affective temperament scores of control subjects. All patients were followed up for at least 1.5 years in order to detect the onset of any major affective disorders, substance use disorders and suicide attempts. Results: Among females, the dominant ANX and DE temperaments were four and three times as common as in a large normative Hungarian sample (for both cases p < 0.01). Among male PD patients, only the dominant DE temperament was slightly overrepresented in a non-significant manner. Females with PD obtained significantly higher scores on ANX, DE and CT subscales of the TEMPS-A, whereas males with PD showed significantly higher scores on ANX, DE and HT temperament subscales compared with the members of a large normative Hungarian sample and also with a gender- and age-matched control group. During the follow-up, newly developed unipolar major depression and bipolar spectrum (bipolar I or II and cyclothymic) disorders appeared in 64% and 22% of subjects, respectively. Conclusions: Our preliminary findings suggest that a specific, ANX-DE-CT affective temperament profile is characteristic primarily for female patients, and an ANX-DE-HT affective temperament profile is characteristic for male patients with PD, respectively. These findings are in line with expectations because PD is an anxiety disorder par excellence on the one hand, whereas, on the other hand, it is quite frequently comorbid with mood (including bipolar) disorders.

Background: Cyclothymic temperament (CT) is an affective disposition often preceding bipolar disorder (BD), and is the most common affective temperament in patients with BD. In depressed patients, CT is a predictor for developing a bipolar course. In a clinical sample of adults with BD and attention deficit hyperactivity disorder (ADHD), CT was associated with higher loads of psychiatric symptoms, somatic comorbidity, impairment, and higher morbidity among first-degree relatives. We aimed to investigate the morbidity and occupational functioning of persons with CT in the general population., Methods: Randomly recruited Norwegian adults (n = 721) were assessed with a 21-item cyclothymic subscale from the TEMPS Autoquestionnaire. Self-reported data were collected on psychiatric symptoms, comorbidity, educational and occupational level, and known family morbidity., Results: Thirteen percent had CT associated with an increased prevalence of ADHD, BD, high scores on the Mood Disorder Questionnaire (MDQ), and childhood and adulthood ADHD symptoms. CT was found in 75% (p < .001) of the bipolar participants, and in 68% (p < .001) of those with a positive MDQ score. CT was associated with more anxiety/depression, substance and alcohol problems, lower educational and occupational levels, and having a first-degree relative with anxiety/depression, alcohol problems, ADHD, and BD., Limitations: The CT subscale alone might include overlapping features with cyclothymic, anxious, irritable, and depressed temperaments, thus increasing the prevalence estimate of CT., Conclusions: CT is a strong predictor of occupational failure and associated with more psychiatric impairment in the participants and their families. CT should be assessed in both mood disorder and ADHD patients., (Copyright © 2019. Published by Elsevier B.V.)

Differences between BD-I and BD-II patients with regard to specific illness characteristics are poorly understood. This study is mainly aimed to compare socio-demographic and clinical characteristics between BD-I and BD-II patients with the goal of clarifying possible predictors of clinical course. The sample of this cohort study is composed of 391 currently euthymic bipolar patients. Participants were all receiving only maintenance treatment; their psychopharmacological regimens and psychopathological conditions were stable at assessment. After univariate analyses, BD-II patients were more likely to be female, had more frequently a recent depressive episode and substance abuse/dependence relative to BD-I subjects. BD-II patients were also less likely to have a positive history of psychiatric conditions in family, psychotic symptoms at first episode, and first depressive illness episode. Moreover, BD-II were older at their illness onset and first treatment than BD-I patients. Furthermore, BD-I were more likely to have higher depressive, manic, anxiety, and symptoms severity than BD-II patients. After logistic regression analyses, being female (OR = 0.289), having psychiatric conditions in family (OR = 0.273), and higher severity of illness at CGI (OR = 0.604) were all significantly associated with BD-II. Additional studies are required to replicate these results, and facilitate the prediction of BD outcomes according to the specified profile., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Background: The concept of Predominant Polarity (PP) provides relevant information for clinical practice and has been widely described as course specifier for Bipolar Disorder (BD), however it has not been incorporated in DSM-5 yet. A descriptive study was conducted to identify clinical patterns associated with PP in outpatients attending a Mental Health Unit., Methods: Clinical and socio-demographic characteristics were assessed from a sample of 118 euthymic outpatients fulfilling DSM 5 criteria for BDI or II recruited at a catchment area. According to their PP, patients were divided into three subgroups: depressive (DPP; 39.0%), manic (MPP; 32.2%) or indeterminate (IPP; 28.8%). Subgroups of PP were compared regarding a comprehensive set of demographic and clinical features., Results: PP subgroups significantly differed in duration of euthymia, measured in months since the last episode (p < 0.04), with MMP patients showing longer periods (42.4 months) than those with DPP and IPP (18.6 and 18.1 months, respectively). Moreover, history of seasonal pattern was significantly higher in the DPP group compared with the PPM group (p < 0.001). There were no significant correlations between PP and type of last episode, length of illness, number of previous admissions, history of psychotic symptoms, or number of suicide attempts., Limitations: Cross sectional design, relatively modest sample size., Conclusions: Our study showed similar results to previous literature regarding distribution of predominant polarity. The association found between PP and duration of euthymia represents a novel finding which awaits confirmation and adds further support to the usefulness of PP in clinical practice., (Copyright © 2018.

Objective: The relationship between temperament and mental health problems is seen very important as we hope to explain the trajectory of this interaction. The aim of this study was to test the validity of affective temperaments for predicting psychiatric morbidity, by explaining the relationships between temperament, anxiety and depression in a community sample., Methods: This was a cross-sectional study. The present sample consisted of 960 participants (347 male, 622 female) with a mean age of M = 28.4 (SD = 10) randomly recruited. Affective temperaments were measured by the brief version of TEMPS-A, depression and anxiety measured with Beck Depression Inventory and Beck Anxiety Inventory., Results: The Cronbach alpha reliability coefficients for affective temperaments were between .72 and .81, for BDI and BAI, were .88 and .90. The study found significant gender differences on depressive [t(959) = -4.2, p<.001], cyclothymic [t(957) = -4.6, p < .001] and anxious temperament [t(957) = -8.2, p < .001], females having higher scores than males, and reverse results on hyperthermic temperament [t(958) = 2.1, p < .045], males having higher scores than females. No gender difference is found in irritable temperament [t(955) = -.581, p < .561]. Affective temperaments were found significant predictors for depression and anxiety. The combination of the depressive temperament and cyclothymic temperament explained the 32% variance of depression and the 25% variance of anxiety., Conclusions: Study findings are consistent with some other studies and stress the importance of screening for effective temperament in order to early identify depression and anxiety. Further investigation is needed to understand what are other factors that influence the relationship between affective temperaments with depression and anxiety.

Sleep disturbances are feasibly linked with poorer outcome in BD. This study aims to cross-sectionally investigate clinical factors associated with sleep disruption in euthymic BD patients. We assessed sleep quality in a sample of 209 euthymic BD patients with the Pittsburgh Sleep Quality Index. After multiple logistic regression analysis controlling for several confounding factors, the variables number of clinical diseases and Hamilton global score remained significant and independently associated with poor sleep quality. Our results suggest that euthymic BD patients presenting poor sleep quality are more likely to have clinical comorbidities and manifest subsyndromal depressive symptomatology., (Copyright © 2018.

High rates of alcohol use disorder (AUD) are reported in people with major depression (MD) and bipolar disorder (BD). Substance abuse problems in adolescence may also indicate risk for future onset of mood disorders, especially BD. Data collected from the Avon Longitudinal Study of Parents and Children (ALSPAC), a large UK birth cohort, allowed information to be collected over several different time points and to test whether problematic alcohol use at age 16 was predictive of vulnerability to hypomanic symptoms at age 23. Controlling for a participant's gender, SES, marital status of the mother, a likely history of maternal depression, and adolescents' level of depressive symptoms at age 16, a hierarchical linear regression revealed that self-reported alcohol use in adolescence predicted the future onset of hypomanic/manic symptoms. Limitations include attrition and relying solely on self-ratings. Despite these limitations, the results suggest problematic alcohol use in adolescence predicts a vulnerability to hypomanic or manic symptoms., (Copyright © 2017 Elsevier Ireland Ltd.

Objectives: Epidemiological studies suggest that cyclothymic disorder is the most prevalent subtype of bipolar disorder (BD). However, it is rarely diagnosed, especially in youth. This may be because it can be difficult to ascertain whether a youth meets diagnostic criteria. Clearer, easy-to-apply criteria could reduce misdiagnosis. The objective oftable this study was to determine whether proposed research diagnostic criteria for cyclothymic disorder (RDCyc), based on DSM-5 criteria, could be quantified and validated in youth., Methods: Participants from the Longitudinal Assessment of Manic Symptoms (LAMS) study were recruited based on symptoms of mania and followed prospectively. RDCyc criteria were: 1) At least one core symptom each of mania and depression; 2) one additional symptom of mania and of depression; 3) persistence over two consecutive six-month periods, and 4) impairment. Exclusionary criteria were having a [hypo]manic or depressive episode. Outcomes at the two-year follow-up were compared between RDCyc youth and other diagnostic groups (BD I/II, BD NOS/non-RDCyc cyclothymic disorder, disruptive behavior disorders [DBD], depression)., Results: Thirty-seven youth met RDCyc criteria. There were no consistent differences between the RDCyc youth and youth with other BD subtypes (ps=0.001-0.960, with all-but-one p value >0.02). RDCyc youth had higher depression (p<0.0005) and mania scores (p=0.001), lower functioning (p=0.012), and higher suicide risk than DBD youth (p=0.001). They had higher mania scores than depressed youth (p.018)., Limitations: The majority of youth in the sample were recruited due to elevated symptoms of mania, which may limit the generalizability of the results. Youth were followed for two years, which may not be long enough to determine whether or not they will eventually develop a manic or depressive episode., Conclusions: Applying RDCyc criteria identified youth who were similar to others with BD and were more impaired than those with DBD. Using these criteria could reduce misdiagnosis and increase our understanding of this prevalent, but largely ignored, diagnosis., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Background: Contrary to DSM-5 definition based on recurrence of low grade hypomanic and depressive symptoms, cyclothymia is better defined in a neurodevelopmental perspective as an exaggeration of cyclothymic temperament. Emotional dysregulation with extreme mood instability and reactivity is the core features of the complex symptomatology., Method: In the present article, we critically reviewed the literature on the diagnosis and treatment of cyclothymia, focusing on the temperamental and neurodevelopmental perspectives., Results: Current epidemiological and clinical research showed the high prevalence and the validity of cyclothymia as a distinct form of bipolarity, frequently associated with multiple comorbidities with anxiety, impulse control, substance use, and so called "personality" disorders. Many patients receive correct diagnosis and treatments after many years of illness, when the superposition of complications reduces the possibility of complete remission. A therapeutic model combining the focus on symptomatic presentations with a temperamental perspective seems to represent an effective approach for cyclothymic patients with complex clinical presentations., Conclusion: Cyclothymic mood instability is an understudied issue despite the evidence of its clinical relevance. Unresolved issues concern its diagnostic delimitation and the possible relationships with emotional dysregulation observed in other neurodevelopmental disorders. We need to confirm the specificity of the disorder and to improve its recognition in early phase of the life, especially in youth. Early recognition means avoiding unnecessary complications and establishing specific treatments and clinical management since the beginning.

Aims: To evaluate the temperament and quality of life (QoL) of patients with PCOS., Materials and Methods: Fifty-three adult patients with PCOS and 38 healthy controls were enrolled in the study. Demographic characteristics including age, education and body mass index (BMI) were recorded. Affective temperaments were assessed by the temperament evaluation of Memphis, Pisa, Paris and San Diego-autoquestionnaire version (TEMPS-A) scale. The general health-related quality of life (HRQoL) instrument used in this study was short Form 36. Hospital anxiety and depression scale (HADS) were also performed., Results: The patients with PCOS had significantly higher rates of depressive, anxious and hyperthymic scores compared to controls. The PCOS patients had significantly lower mean SF-36 health summary scores., Conclusions: TEMPS-A seems to be an easy and reliable test to evaluate temperament in PCOS patients.

Aim: To investigate affective pathology in patients with adolescent bulimia nervosa (BN) and to analyze comorbid mutual influences of these clinical entities., Material and Methods: A sample consisted of 52 young female patients, aged from 13.9 to 17.4 years, who simultaneously meet ICD-10 criteria of F50.2 - typical BN and F30-F39 - mood disorders. The Eating Attitudes Test (EAT-26) and the Beck Depression Inventory were used for psychometric assessment. Duration of follow-up ranged from 1 to 7 years., Results and Conclusion: The common forms of affective disorders comorbid with adolescent BN were dysthymia and bipolar affective disorder (BAD) type II. Less often BN manifested in association with psychogenic endoform depressions. And the less typical was comorbidity of BN with endogenous recurrent unipolar depression. The normalization of mood and transition depression to hypomania contributed to the remission of eating disorders. Worst clinical and social outcome was detected in patients with long-term persistent hypothymia caused by dysthymia or protracted depressive episodes of recurrent depressive disorder. A more favorable outcome was seen in patients with alternation of depression and hypomania in the structure of the BAD type II and the best outcome in patients with single episode of psychogenic endoform depression.

Objective: DSM-5 introduced the "with mixed features" specifier for major depressive episodes. The authors assessed the prevalence and phenomenology of mixed depression among bipolar disorder patients and qualitatively compared a range of diagnostic thresholds for mixed depression., Method: In a naturalistic study, 907 adult outpatients with bipolar disorder participating in the Stanley Foundation Bipolar Network were followed longitudinally across 14,310 visits from 1995 to 2002. The Inventory of Depressive Symptomatology-Clinician-Rated Version (IDS-C) and the Young Mania Rating Scale (YMRS) were administered at each visit., Results: Mixed depression, defined as an IDS-C score ≥15 and a YMRS score >2 and <12 at the same visit, was observed in 2,139 visits (14.9% of total visits, and 43.5% of visits with depression) by 584 patients (64.4% of all patients). Women were significantly more likely than men to experience subthreshold hypomania during visits with depression (40.7% compared with 34.4%). Patients with one or more mixed depression visits had more symptomatic visits and fewer euthymic visits compared with those with no mixed depression visits. DSM-5-based definitions of mixed depression (ranging from narrower definitions requiring ≥3 nonoverlapping YMRS items concurrent with an IDS-C score ≥15, to broader definitions requiring ≥2 nonoverlapping YMRS items) yielded lower mixed depression prevalence rates (6.3% and 10.8% of visits, respectively) but were found to have similar relationships to gender and longitudinal symptom severity., Conclusions: Among outpatients with bipolar disorder, concurrent hypomanic symptoms observed during visits with depression were common, particularly in women. The DSM-5 diagnostic criteria for depression with mixed features may yield inadequate sensitivity to detect patients with mixed depression.

Bipolar disorder is a severe psychiatric disorder, characterized by depressive, manic and mixed episodes. The illness affects about 1-2 % of the population. Bipolar I disorders affect both genders equally, whereas bipolar II disorders seem to occur more frequently in women. The classification of the different subtypes of bipolar disorders is done depending on the severity and frequency of the episodes. Other subtypes beside bipolar I and bipolar II disorder are rapid cycling (more than 4 episodes of mania, depression, hypomania or mixed state in one year) and cyclothymia (hypomanic and subdepressive symptoms over a two year period). Besides a thorough psychiatric and neurological examination, further clinical tests should be performed in order to exclude differential diagnosis (psychiatric as well as neurological and somatic diseases). The course of the illness is often negatively affected by the high frequency of psychiatric and somatic comorbidities. After all the prognosis of bipolar disorder is depending on the individual course of the illness. Notably comorbidities and psychotic symptoms seem to have a negative influence on the prognosis.

Background: Sleep disturbance in bipolar disorder (BD) is common during and between mood episodes. In recovered (euthymic at least two months) BD patients, we assessed sleep compared to controls and its relationships with residual mood symptoms and mood episode recurrence., Method: Recovered Stanford University BD Clinic patients diagnosed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and monitored with the STEP-BD Clinical Monitoring Form (CMF) for >1 year and healthy controls completed the Pittsburgh Sleep Quality Index (PSQI). PSQI parameters were compared in BD patients versus controls, and the most robustly differentiating PSQI parameter was assessed in relationship to residual mood symptoms, and time to mood episode recurrence in BD patients., Results: Eighty nine recovered BD patients compared to 56 healthy controls had significantly worse PSQI global score, more sleep medication use, longer sleep latency, and worse daytime dysfunction. PSQI global score had the greatest BD patient versus control effect size, and among BD patients, correlated significantly with residual mood symptoms and predicted earlier mood episode recurrence, even after covarying for residual mood symptoms., Limitations: Use of subjective (PSQI) rather objective (polysomnography) sleep metric. Statistical power limited by small sample size. Potential psychotropic medication confound. Northern California tertiary BD clinic referral sample., Conclusion: Further research is needed to confirm that in recovered BD patients, poor sleep quality correlates with residual mood symptoms, and independently predicts mood episode recurrence. If confirmed, these observations suggest potential mood benefit for focusing on sleep quality in interventions for recovered BD patients., (Published by Elsevier B.V.)

Diagnosing a pediatric patient with bipolar disorder can pose a challenge for clinicians. Children typically do not present with the full criteria for a mood episode and may have symptoms of other disorders such as attention-deficit/hyperactivity disorder, oppositional defiant disorder, anxiety disorders, and other mood disorders, which may complicate the diagnostic process. By diligently interviewing parents and children about behaviors, thoroughly reviewing family histories, and systematically ruling out other disorders, clinicians can provide an accurate diagnosis for their pediatric patients., (© Copyright 2016 Physicians Postgraduate Press, Inc.)

Data emerging from both academic centers and from public and private outpatient facilities indicate that from 20% to 50% of all subjects that seek help for mood, anxiety, impulsive and addictive disorders turn out, after careful screening, to be affected by cyclothymia. The proportion of patients who can be classified as cyclothymic rises significantly if the diagnostic rules proposed by the DSM-5 are reconsidered and a broader approach is adopted. Unlike the DSM-5 definition based on the recurrence of low-grade hypomanic and depressive symptoms, cyclothymia is best identified as an exaggeration of cyclothymic temperament (basic mood and emotional instability) with early onset and extreme mood reactivity linked with interpersonal and separation sensitivity, frequent mixed features during depressive states, the dark side of hypomanic symptoms, multiple comorbidities, and a high risk of impulsive and suicidal behavior. Epidemiological and clinical research have shown the high prevalence of cyclothymia and the validity of the concept that it should be seen as a distinct form of bipolarity, not simply as a softer form. Misdiagnosis and consequent mistreatment are associated with a high risk of transforming cyclothymia into severe complex borderline-like bipolarity, especially with chronic and repetitive exposure to antidepressants and sedatives. The early detection and treatment of cyclothymia can guarantee a significant change in the long-term prognosis, when appropriate mood-stabilizing pharmacotherapy and specific psychological approaches and psychoeducation are adopted. The authors present and discuss clinical research in the field and their own expertise in the understanding and medical management of cyclothymia and its complex comorbidities., (Copyright © 2015 Elsevier B.V.

Background: Bipolar disorder (BD) phenomenology in children and adolescents remains contentious. The study investigated Australian children and adolescents with bipolar I disorder (BD-I), bipolar II disorder (BD-II), or BD not otherwise specified (BD-NOS)., Methods: Index episode demographics, symptomatology, functioning and diagnostic data were compared for 88 participants (63 female) aged 8-18 years (M=14.8, SD=2.5) meeting DSM-IV-TR criteria for BD-I (n=24), BD-II (n=13) or BD-NOS (n=51)., Results: BD-I had higher rates of previous episodes, psychotropic medication (compared to BD-II but not BD-NOS), rates of inpatient admissions (compared to BD-NOS), and number of inpatient admissions (compared to BD-II). BD-II had lower rates of lifetime depression and anxiety disorders, higher frequency of hypomania, shorter duration of illness, and fewer previous episodes. BD-NOS had younger age of onset, chronic course, irritability and mixed presentation. All BD subtypes had high rates of self-harm (69.3%), suicidal ideation (73.9%), suicide attempts (36.4%), psychiatric admission (55.7%), and psychosis (36.4%)., Limitations: There were relatively small numbers of BD-I and BD-II. Diagnoses were based on retrospective recall., Conclusions: All BD subtypes had high levels of acuity and clinical risk. In accord with previous results, BD-I and BD-II participants' phenomenology was consistent with classical descriptions of these subtypes. BD-NOS participants were younger, with less euphoric mania but otherwise phenomenologically on a continuum with BD-I, suggesting that child and adolescent BD-NOS may be an early and less differentiated phase of illness of BD-I or BD-II and hence a target for early intervention., (Copyright © 2014 Elsevier B.V.

Background: The relationship between temperament and sexual orientation has been poorly characterized. We have used the Affective and Emotional Composite Temperament (AFECT) model to evaluate this association in a large population sample., Methods: Data from 16,571 subjects between 21 and 45 years old (mean age=29.1±6.3 yrs, 69.4% females) was collected anonymously through Internet in Brazil., Results: Regarding affective temperaments, male cyclothymics and dysphorics had the lowest percentage of people with heterosexual orientation and the highest percentages of people with bisexual and homosexual orientations. The opposite profile was observed in hyperthymic and euthymic types. Among females, the volatile, cyclothymic, apathetic, disinhibited and euphoric types were less often observed in people with "pure" heterosexual orientation and more often in people with bisexual orientation. In men only, homosexuality was more common among the depressive, cyclothymic and dyphorics temperaments. Emotional trait analysis showed that heterosexual subjects differed statistically from all other groups by having higher scores of coping and stability and lower scores of sensitivity and desire. Overall, the effect sizes were small to moderate, with the largest differences between "pure" heterosexuals and people with bisexual orientation, particularly in women. Subjects with heterosexual orientation who have had homosexual experience and those with homosexual orientation presented intermediate scores., Limitations: Cross-sectional design, lack of potentially important covariates (e.g., maltreatment) and data collected by Internet only., Conclusion: Externalized and unstable traits were associated mainly with bisexuality. The group of heterosexuals with homosexual fantasies or experiences offers a new approach for the study of sexual orientation., (Copyright © 2015 Elsevier B.V. All rights reserved.)

Background: Previously, we compared the hyperthymic scores of residents in Sapporo, Koshigaya, and Oita (which are located at latitudes of 43°N, 36°N, and 33°N in Japan, respectively) using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-auto questionnaire version (TEMPS-A). We found that residents who lived at lower latitudes had higher hyperthymic temperament scores; however, the mechanism of the effect of latitude on hyperthymic temperament remained unclear. The current study examined the mediators of the latitude effect in additional regions with different annual temperatures and amounts of ambient sunshine., Methods: The Japanese archipelago stretches over 4000 km from north to south and has four large islands: Hokkaido, Honshu, Shikoku, and Kyushu. In addition to the TEMPS-A previously reported data collected at Sapporo (latitude 43°N), Koshigaya (36°N), and Oita (33°N), we collected the TEMPS-A data of 189 and 106 residents from Takaoka (36°N) and Obihiro (42°N), respectively. Taken together, these five regions have different patterns (i.e., highs and lows) of annual ambient total sunshine (hours) and mean temperature (°C). The effect of latitude, sunshine, and temperature on affective temperaments was analyzed for five Japanese regions., Results: Multiple regression analyses revealed that latitude predicted significant variance in hyperthymic temperament. Ambient temperature, but not sunshine, significantly affected hyperthymic temperament., Limitations: The light exposure that residents actually received was not measured. The number of regions studied was limited. The findings might not generalize to residents across Japan or other countries., Conclusions: The present findings suggest that latitude affects hyperthymic temperament, and ambient temperature might mediate this effect., (Copyright © 2014 Elsevier B.V.

The phenomenology of dissociative disorders may be complex and sometimes confusing. We describe here two cases who were initially misdiagnosed. The first case concerned a 61 year-old woman, who was initially diagnosed as an isolated dissociative fugue and was actually suffering from severe major depressive episode. The second case concerned a 55 year-old man, who was suffering from type I bipolar disorder and polyvascular disease, and was initially diagnosed as dissociative fugue in a mooddestabilization context, while it was finally a stroke. Yet dissociative disorders as affective disorder comorbidity are relatively unknown. We made a review on this topic. Dissociative disorders are often studied through psycho-trauma issues. Litterature is rare on affective illness comorbid with dissociative disorders, but highlight the link between bipolar and dissociative disorders. The later comorbidity often refers to an early onset subtype with also comorbid panic and depersonalization-derealization disorder. Besides, unipolar patients suffering from dissociative symptoms have more often cyclothymic affective temperament. Despite the limits of such studies dissociative symptoms-BD association seems to correspond to a clinical reality and further works on this topic may be warranted., (Copyright © 2014 L’Encéphale.

Background: Comorbidity between ADHD and Bipolar Disorder (BD) is associated with greater severity of BD. The current study aims at investigating, in a specialized mood disorders clinic, the percentage of comorbid ADHD-BD subjects and assessing the impact of ADHD on the severity of BD., Methods: Out of 539 mood disorders subjects, the medical records of 138 BD subjects were scrutinized in terms of their clinical and demographic characteristics, and their scores at the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist were logged. Those positively scoring at the ASRS-v1.1 underwent clinical assessment by a senior psychiatrist specialized in ADHD. Comorbid ADHD-BD subjects were then compared with BD sufferers without ADHD., Results: Sixty-three (45.65%) of the participants were screened positive at the ASRS-v1.1. 49 were clinically assessed for the presence of ADHD. Only 27 (55%) received a diagnosis of ADHD. Comorbid ADHD-BD subjects were found to be younger at the onset of BD, showed higher numbers of depressive episodes, more anxiety and substance use disorders, more borderline personality traits and greater cyclothymic temperament. Comorbid BD-ADHD subjects reported more childhood emotional abuse., Limitations: Some subjects were unreachable and thus not clinically assessed for ADHD., Conclusions: More than 20% of BD subjects were suffering from ADHD. The comorbidity of the two disorders was associated with worse outcomes, possibly resulting from stressful early-life events. More than 40% of the subjects who scored positively at the ASRS-v1.1 did not suffer from ADHD, which suggests that this scale should be used with caution in BD subjects., (Copyright © 2014 Elsevier B.V.

Background: The aim was to determine the risk of Mood Disorders (MD), particularly Bipolar Disorders (BD), in Multiple Sclerosis (MS) using standardized psychiatric diagnostic tools., Methods: Case-control study., Cases: 201 consecutive-patients with MS., Controls: 804 sex- and age-matched subjects without MS, randomly selected from a database concurrently used for an epidemiological study on the MD prevalence in the community. Psychiatric diagnoses according to DSM-IV were determined by physicians using structured interview tools (ANTAS-SCID)., Results: Compared to controls, MS patients had a higher lifetime prevalence of DSM-IV Major Depressive Disorders (MDD; P<0.0001), BD I (P=0.05), BD II (P<0.0001) and Cyclothymia (P=0.0001). As people with MS had a higher risk of depressive and bipolar spectrum disorders, ratio MDD/bipolar spectrum disorders was lower among cases (P<0.005) indicating a higher association with Bipolar Spectrum Disorders and MS., Limitations: MS diagnosis was differently collected in cases and controls. Even if this might have produced false negatives in controls, it would have reinforced the null hypothesis of no increased risk for MD in MS; therefore, it does not invalidate the results of the study., Conclusions: This study was the first to show an association between BD and MS using standardized diagnostic tools and a case-control design. The results suggest a risk of under-diagnosis of BD (particularly type II) in MS and caution in prescribing ADs to people with depressive episodes in MS without prior excluding BD. The association between auto-immune degenerative diseases (like MS) and BD may be an interesting field for the study of the pathogenic hypothesis., (© 2013 Published by Elsevier B.V.)

Background: To 1) establish the lifetime and 12-month prevalence of DSM-5 bipolar and related disorders including the new algorithmically defined conditions grouped within Other Specified Bipolar and Related Disorders (OSBARD) as well as hyperthymic personality in a randomly selected community sample, and 2) determine the clinical relevance of the OSBARD category in terms of sociodemographic characteristics, course, comorbidity and treatment patterns by comparing the subjects of this category to those with bipolar-I (BP-I), bipolar-II (BP-II), major depressive disorder (MDD), and those with no history of mood disorders., Methods: The semi-structured Diagnostic Interview for Genetic Studies was administered by masterslevel psychologists to a random sample of an urban area (n=3'719)., Results: The lifetime prevalence was 1.0% for BP-I, 0.8% for BP-II, 1.0% for OSBARD and 3% for hyperthymic personality. Subjects with OSBARD were more severely affected than subjects without a history of mood disorders regarding almost all clinical correlates. Compared to those with MDD, they also revealed an elevated risk of suicidal attempts, lower global functioning, more treatment seeking and more lifetime comorbidity including anxiety, substance use and impulse-control disorders. However, they did not differ from subjects with BP-II., Limitations: Small sample sizes for bipolar and related disorders and potential inaccurate recall of symptoms., Conclusions: The modifications of diagnostic criteria for manic/hypomanic episodes according to the DSM-5 only marginally affect the prevalence estimates for BP-I and BP-II. The new DSM-5 OSBARD category is associated with significant clinical burden, is hardly distinct from BP-II with respect to clinical correlates and deserves similar clinical attention., (Copyright © 2014 Elsevier B.V.

Temperament is considered as a biological disposition reflected by relatively stable features related to mood and reactivity to external and internal stimuli, including variability in emotional reactions. The aim of the present study is to test the hypothesis that affective temperaments might differ according to co-occurring mood disorders among patients with alcohol and/or opiate dependence; to explore the relationship between temperaments and dual substance use disorders (SUDs, alcohol and other drugs). Ninety-two patients attending an alcohol addiction treatment facility and 47 patients in an opiate addiction treatment facility were assessed for SUDs, mood disorders and affective temperaments using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego 39-item auto-questionnaire. Comparison of patients with bipolar disorder, depressive unipolar disorder and no (or substance-induced) mood disorder revealed significant differences for the cyclothymic subscale, with highest scores among patients with bipolar disorder. No difference was observed for the depressive, irritable, hyperthymic and anxious subscales. After adjustment for age, gender and bipolar disorder, irritable temperament was a significant risk factor for past or present history of drug use disorders in patients treated for alcohol addiction (odds ratio [OR] 1.42, 95% confidence interval [CI] 1.05-1.93). Anxious temperament was a significant risk factor for history of alcohol use disorders in patients treated for opiate addiction (OR 3.30, 95% CI 1.36-7.99), whereas the hyperthymic subscale appeared as a significant protective factor (OR 0.65, 95% CI 0.42-0.99). The results highlight the need to consider temperamental aspects in further research to improve the long-term outcome of patient with addictive disorders, who often present complex comorbidity patterns.

Background: Suicidal behaviour is a major health problem, particularly among patients with depressive disorders., Aims: To determine the frequency of suicidal behavior among sample of patients with recurrent depressive disorder and to explore the relationship between suicidal behavior and cyclothymic temperament in these patients., Methods: This was a cross-sectional study bearing on 98 patients (43 men and 55 women, mean age of 46.8 ± 9.9 years) followed for recurrent depressive disorder according to the criteria of DSM-IV recruited during partial or complete recovery interval. Information about suicidal behavior was collected from medical records. Cyclothymic temperament (CT) was assessed using the cyclothymic subscale (21 items). Patients who had scores above the threshold score of 10 and were considered as cyclothymic (CT+ group) and other patients were considered non-cyclothymic (CT- group)., Results: History of suicide attempts were reported in 22.4% of patients. The mean number of previous suicide attempts was significantly higher among patients in the TC+ group (0.7 ± 1.4) versus 0.2 ± 0.6 for patients in the TC- group (p=0.01). Recurrent thoughts of death and suicide attempts in the last depressive episode, were significantly higher in the CT+ group, with a 57.5% versus 24.6% in the CT- group, (p=0.001) and 33.3% versus 10.7% in the TC- group (p=0.006). A multivariate analysis retained the TC as an independent factor associated with suicidal behavior, with two other factors: the young age of patients and the frequency of previous hospitalizations., Conclusion: Our findings the frequency of suicidal behavior and suggest the involvement of CT in the increased risk of suicide among patients with recurrent depressive disorder.

The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) nomenclature for the co-occurrence of manic and depressive symptoms (mixed states) has been revised in the new DSM-5 version to accommodate a mixed categorical-dimensional concept. The new classification will capture subthreshold non-overlapping symptoms of the opposite pole using a "with mixed features" specifier to be applied to manic episodes in bipolar disorder I (BD I), hypomanic, and major depressive episodes experienced in BD I, BD II, bipolar disorder not otherwise specified, and major depressive disorder. The revision will have a substantial impact in several fields: epidemiology, diagnosis, treatment, research, education, and regulations. The new concept is data-driven and overcomes the problems derived from the extremely narrow definition in the DSM-IV-TR. However, it is unclear how clinicians will deal with the possibility of diagnosing major depression with mixed features and how this may impact the bipolar-unipolar dichotomy and diagnostic reliability. Clinical trials may also need to address treatment effects according to the presence or absence of mixed features. The medications that are effective in treating mixed episodes per the DSM-IV-TR definition may also be effective in treating mixed features per the DSM-5, but new studies are needed to demonstrate it., (Copyright © 2013 Elsevier B.V.

Background: Being bullied has been increasingly recognized as a risk factor for the development of psychiatric disorders, but there is very limited evidence on the association of bullying with temperament., Methods: The data was collected in a large web-survey on psychological and psychiatric measures (BRAINSTEP). Bullying was assessed with a question on time exposed to bullying (none, <1 year, 1-3 years and >3 years) during childhood and adolescence. Emotional traits and affective temperaments were evaluated with the Affective and Emotional Composite Temperament Scale (AFECTS). The final sample consisted of 50,882 subjects (mean age 30.8 ± 10.4 years, 73.4% females) with valid answers., Results: About half of the sample reported exposure to bullying and ∼10% reported being victimized by peers for longer than 3 years. Longer exposure to bullying was associated with lower Volition, Coping and Control scores, and more Emotional Sensitivity, Anger and Fear, with statistical significance between all groups. To a lower degree, exposure to bullying was associated with lower Caution and higher Desire scores. Bullying victimization was also associated with a much lower proportion of euthymic and hyperthymic types in both genders, which was compensated by an increase mainly in the proportion of depressive, cyclothymic and volatile types., Limitations: Retrospective assessment of bullying with a single question on time exposed to bullying and use of self-report instruments only., Conclusions: Being bullied was associated with a broad and profound impact on emotional and cognitive domains in all dimensions of emotional traits, and with internalized and unstable affective temperaments., (Copyright © 2012 Elsevier B.V.

Based on the observation of 26 female patients, authors present a specific subtype of bipolar disorder - a somatoreactive cyclothymia which develops concomitantly with cancer. The affective disorder manifests itself as an acceptor of the clinical rhythm of cancer: the first and recurrent affective episodes coincide with the key stages of the disease.

Background: Studies on mixed depression have been conducted so far on the basis of DSM-IV manic symptoms, i.e., a list of 7 symptoms which may provide limited information on the subsyndromal features associated with a full depressive episode., Methods: As part of the EPIDEP National Multisite French Study of 493 consecutive DSM-IV major depressive patients evaluated in at least two semi-structured interviews 1 month apart, 102 (23.8%) were classified as mixed depressives (≥3 hypomanic symptoms), and 146 (34%) as pure depressives (0 hypomanic symptom), after exclusion of bipolar I patients; hypomanic symptoms were assessed with the Multiple Visual Analog Scales of Bipolarity (MVAS-BP, 26 items) of Ahearn-Carroll in a self assessment format. A narrower definition of mixed depression, resting on those MVAS-BP items referring to DSM-IV hypomanic symptoms was also tested, as a sensitivity analysis., Results: Compared to pure depressives, mixed depressive patients had more psychotic symptoms, atypical features and suicide attempts during their index episode; their illness course was characterized by early age at onset, frequent episodes, rapid cycling, and comorbidities. Mixed depressive patients were more frequently bipolar with a family history of bipolar disorder, alcohol abuse, and suicide. A dose-response relationship was found between intradepression hypomania and several clinical features, including temperament measures. The following independent variables were associated with mixed depression: hyperthymic temperament, cyclothymic temperament, irritable temperament, and alcohol abuse. Using the narrower definition of mixed depression missed risk factors such as suicidality and comorbidities., Limitations: The following are the limitations of this study: retrospective design, recall bias, lack of sample homogeneity, no cross-validation of findings by hetero-evaluation of hypomanic symptoms., Conclusions: EPIDEP data showed the feasibility and face validity of self-assessment of intradepressive hypomania. They replicated previous findings on the severity and high suicidal risk of mixed depression profile. They confirmed, for mixed depression, that mixed states occur when mood episodes are superimposed upon temperaments of opposite polarity. They finally suggested that a definition of mixed depression only based on DSM-IV-TR hypomanic symptoms may not allow to identify the most unstable subforms of the entity., (Copyright © 2012 Elsevier B.V.

Background: Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder in children and adults. Many ADHD patients experience affective symptoms that resemble the cyclothymic temperament trait, which is suggested to be a part of the bipolar spectrum. However, the relationship between adult ADHD and cyclothymic temperament has never been systematically studied., Methods: A sample of 586 clinically diagnosed Norwegian adult ADHD patients and 721 population derived controls responded to the 21-item cyclothymic subscale of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego auto-questionnaire (TEMPS-A). Self-reported data on psychiatric symptoms, comorbidity, educational and occupational level, and known comorbidity in family members, including bipolar disorder, was also obtained., Results: The mean TEMPS-A scores were 13.0 for patients and 4.6 for controls (p<0.001), and 71% of the patients compared to 13% of the controls were classified as having a cyclothymic temperament (TEMPS score ≥11 points). Among ADHD patients, cyclothymic temperament was strongly associated with more childhood and adult ADHD symptoms, lower educational and occupational achievements and increased psychiatric comorbidity, including bipolar disorder (10%). In addition, 49% screened positive on the Mood Disorder Questionnaire., Limitations: Although the cyclothymic TEMPS-A scale has been used in clinical settings in Norway for many years, it has not yet been officially validated., Conclusions: Cyclothymic temperament is highly prevalent in adults with ADHD, and this characterises a subgroup of more psychiatrically impaired individuals, possibly reflecting an underlying affective instability with a pathophysiology closer to the bipolar spectrum disorders., (Copyright © 2012 Elsevier B.V.

Background: The clinical and dimensional features associated with suicidal behaviour in bipolar patients during euthymic states are not well characterised., Methods: In a sample of 652 euthymic bipolar patients, we assessed clinical features with the Diagnostic Interview for Genetics Studies (DIGS) and dimensional characteristics with questionnaires measuring impulsivity/hostility and affective lability/intensity. Bipolar patients with and without suicidal behaviour were compared for these clinical and dimensional variables., Results: Of the 652 subjects, 42.9% had experienced at least one suicide attempt. Lifetime history of suicidal behaviour was associated with being a woman, a history of head injury, tobacco misuse and indicators of severity of bipolar disorder including early age at onset, high number of depressive episodes, positive history of rapid cycling, alcohol misuse and social phobia. Indirect hostility and irritability were dimensional characteristics associated with suicidal behaviour in bipolar patients, whereas impulsivity and affective lability/intensity were not associated with suicidal behaviour., Limitations: This study had a retrospective design with no replication sample., Conclusions: Bipolar patients with earlier onset, mood instability (large number of depressive episodes, rapid cycling) and/or particular addictive and anxiety comorbid disorders might be at high risk of suicidal behaviour. In addition, hostility dimensions (indirect hostility and irritability), may be trait components associated with suicidal behaviour in euthymic bipolar patients., (Copyright © 2011 Elsevier Masson SAS.

Objective: While there is an increasing recognition of the role of subthreshold symptomatology in bipolar disorder, little attention has been dedicated to its only formally acknowledged subtype, cyclothymic disorder. The aim of this investigation was to provide a controlled evaluation of DSM-IV cyclothymic disorder by using a broad assessment strategy geared to subclinical signs., Methods: Sixty-two patients who met the DSM-IV criteria for cyclothymic disorder and did not present comorbidity with other mood disorders, alcohol and drug abuse, and borderline personality disorder and 62 control subjects matched for sociodemographic variables were administered the Structured Interview for Diagnostic Criteria for Psychosomatic Research (DCPR), the Clinical Interview for Depression (CID) and the Mania Scale (MAS)., Results: In DSM-IV terms, there was an overlap with anxiety disorders in more than half of the cases. About 3 patients out of 4 were found to present with at least one DCPR syndrome (particularly demoralization and irritable mood). Cyclothymic patients displayed significantly higher levels of depressive and anxiety disturbances on the CID, with particular reference to reactivity to social environment. They also had significantly higher scores on the MAS., Limitations: The study was cross-sectional and the sample, because of the exclusion criteria, may not be representative of the clinical populations in psychiatric settings., Conclusion: In our patients with cyclothymia, without comorbidity with major mood disorders, DSM-IV anxiety disorders, psychosomatic clinical syndromes (irritable mood, demoralization) and subclinical symptoms such as reactivity to social environment resulted to be more frequent than in controls. The use of a broad assessment strategy aimed at subclinical symptomatology may help identifying clinical phenomena that cut across the current definition of subthreshold forms of bipolar disorder., (Copyright © 2012 Elsevier B.V.

Cyclothymic disorder is a subtype of bipolar disorder included in the Diagnostic and Statistical Manual of Mental Disorders since 1980, but largely neglected in research. Additionally, it is rarely diagnosed clinically, in spite of evidence that it may be the most prevalent form of bipolar disorder. Neglect has contributed to confusion about the diagnosis and clinical presentation of cyclothymic disorder. Its status as a mood disorder is also ambiguous due to overlap in terminology and symptoms with temperament and personality disorders. Subthreshold bipolar disorder appears more prevalent among young people than previously thought, and follows a range of trajectories from remission to escalation-raising questions about risk factors and traits associated with the varied course. Cyclothymic disorder may be an important diathesis for major mood disorders. Constructs such as cyclothymic disorder link major mood disorder and peri-clinical fluctuations of mood, thus warranting a prominent role in dimensional models of mood and psychopathology. Current evidence indicates that cyclothymic disorder is a prevalent and highly impairing disorder on the bipolar spectrum, with the potential to make unique contributions to our understanding of the risk factors and outcomes associated with bipolar disorder. The inclusion of cyclothymic disorder in future research studies is essential to accurate diagnosis and effective treatment for the full spectrum of bipolar disorder, as well as understanding the developmental trajectory of bipolar spectrum disorders., (Copyright © 2012 Elsevier Ltd.

Background: Although it is accepted that patients with delusional disorder can show co-existing depression, comorbidity with bipolar disorder is not a recognised feature., Method: Case report of patients who showed both delusional disorder and mania or hypomania. The patients were examined using lifetime structured psychiatric interview where possible., Results: Four patients are described who met criteria for delusional disorder, with durations ranging from 2 to 15 years, and also experienced one or more episodes of mania or hypomania., Limitations: Case reports cannot quantify a clinical association., Conclusions: These cases suggest that there is an association between delusional disorder and affective disorder which goes beyond the occurrence of depressive symptoms in the disorder., (Copyright © 2011 Elsevier B.V.

Background: Tobacco use has been associated with externalized personality traits. Our aim was to evaluate the association of smoking with emotional and affective temperaments in a large sample., Methods: In this cross-sectional web-based survey, volunteers completed the Combined Emotional and Affective Temperament Scale (CEATS), which assesses emotional (fear, drive, anger, and control) and affective temperaments (e.g. cyclothymic, irritable), and questions about smoking., Results: Among the 5379 subjects (1370 males), there were 60% non-smokers, 17% quitters and 23% current smokers. Non-smokers had higher fear and control and lower anger than quitters and smokers, and higher drive than smokers. Quitters had higher drive and control and lower anger than smokers. Smoking was lower among apathetics, depressives, euthymics and hyperthymics and higher in cyclothymics and labiles. Lower drive and higher anger were associated with heavier smoking. Less adaptive temperament was related to higher prevalence of and heavier smoking., Limitations: The data was collected from a convenience sample by the internet, and most volunteers assessed the instrument through a psychoeducational website for bipolar spectrum disorders, leading to a higher proportion of cyclothymics; the assessment of smoking habits was limited to two questions; the study was cross-sectional., Conclusions: Smoking was associated with lower fear, control and drive, higher anger and unstable externalized affective temperaments. Lower control and higher anger were associated with being a heavy smoker and current smoking. Assessment of temperament may help decision about treatments for smoking cessation., (Copyright © 2010 Elsevier B.V. All rights reserved.)

Background: Bipolar disorder comorbidity in obsessive-compulsive disorder (OCD) has relevant implications on the symptomatological expression, complications and pharmacologic treatment of the disorder. Relatively few data exist on OCD comorbid with soft-bipolar forms. The aims of the study are to evaluate affective temperaments in patients with OCD and to analyze differences in socio-demographic and clinical characteristics according to the presence or absence of cyclothymic temperament., Methods: The sample consisted of 167 patients with a principal diagnosis of OCD (DSM-IV-TR). Affective temperaments have been evaluated through the Italian semistructured interview version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-I)., Results: A total of 90 patients (53.9%) were diagnosed with a dominant affective temperament. Cyclothymic affective temperament (CT) was the most represented in the sample of OCD patients (19.2%). Patients with CT showed significant lower mean age at onset, higher scores at the HAM-A, more repeating compulsions, higher rates of eating disorder comorbidity, OCD spectrum disorder comorbidity and higher rates of Axis II comorbidity (particularly Cluster A)., Limitations: Recruitment of OCD patients from a tertiary center. Absence of an investigation about treatment implications associated with cyclothymic temperament., Conclusions: Patients with OCD and CT could be more severe and complicated compared to patients without CT. Moreover, individuals with OCD spectrum disorders may be vulnerable to bipolarity. Systematic assessment of affective temperament is necessary to detect OCD with such a soft-bipolar comorbidity., (Copyright © 2010 Elsevier B.V. All rights reserved.)

In the history of the nosographies in psychiatry, the affective disorders were gradually distinguished from the other categories of mental disorders, until being considered as separate illness entities, such as what Kraepelin named manic-depressive insanity at the end of the 19th century. The latter will be subsequently divided in two main categories, the bipolar disorder on the one hand and recurrent depression on the other hand, this separation being still current, and extensively diffused by the mean of the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM, whose revisions largely determine the evolution of the contemporary nosographic models, mainly relies on a categorical approach of the mental disorders. The next revision will probably continue to follow this kind of approach, even if the use of dimensional components could also be developed. In the future, true nosographic advances can be waited from clinical epidemiology studies, as those which recently made it possible to highlight various sub-types of affective disorders on the basis of clinical, biographical or temperamental characteristics. Etiological approaches, centered on the pathophysiology of the affective disorders, could also contribute to build nosographic models on the basis of an objective knowledge on these diseases., (Copyright © 2010 L'Encéphale.

Background: Behavioural addictions (BAs) can be understood as disorders characterized by repetitive occurrence of impulsive and uncontrolled behaviours. Very few studies have investigated their association with mood disorders. The present study was undertaken to determine the prevalence of the main behavioural addictions in a sample of bipolar outpatients in euthymic phase or stabilised by medications and to investigate the role of impulsivity and temperamental and character dimensions., Methods: One-hundred-fifty-eight Bipolar Disorder (BD) (DSM-IV) outpatients were assessed with tests designed to screen the main behavioural addictions: pathological gambling (SOGS), compulsive shopping (CBS), sexual (SAST), Internet (IAD), work (WART) and physical exercise (EAI) addictions. TCI-R and BIS-11 were administered to investigate impulsivity and personality dimensions mainly associated with BAs. The clinical sample has been compared with 200 matched healthy control subjects., Results: In bipolar patients, 33% presented at least one BA respect to the 13% of controls. Significantly higher scores at the scales for pathological gambling (p<.001), compulsive buying (p<.05), sexual (p<.001) and work addictions (p<.05) have been found. Self-Directness (p=.007) and Cooperativeness (p=.014) scores were significantly lower while impulsivity level was significantly higher (p=.007) in bipolar patients with BA than those without BA., Conclusions: To our knowledge, this is the first study investigating the prevalence of behavioural addictions in BD showing a significant association of these disorders. BAs are more frequent in bipolar patients than in healthy controls and are related to higher impulsivity levels and character immaturity., (2010 Elsevier B.V. All rights reserved.)

Objective: Most research on the symptomatic burden in bipolar disorder has included patients enrolled exclusively from tertiary centers, and only a few studies have analyzed factors related to it. We investigated the proportion of time and the proportion of visits with symptoms in a cohort of bipolar outpatients followed-up for 18 months, as well as the associated variables., Methods: 296 DSM-IV-TR bipolar outpatients were included in a naturalistic longitudinal follow-up study, with quarterly assessment. Euthymia was defined by a Hamilton Depression Rating Scale score <7 and Young Mania Rating Scale score <5. Depressive episode, by a HDRS score of >17, hypomanic episode by a YMRS score of 10-20, and manic episode by a YMRS score >20. Sub-syndromal symptoms required scores of 7-17 in HDRS and 5-10 in YMRS. Based on a detailed recall of affective symptoms in the time between interviews, time in episode was also determined., Results: Patients were symptomatic for one third of the follow-up, and also one third of the visits. They spent three times more days depressed than manic or hypomanic. More prior affective episodes were related both to more time symptomatic and more visits with symptoms., Limitations: Some of the data were collected retrospectively. Treatment was naturalistic., Conclusions: In a bipolar outpatient cohort from Spain, time with symptoms was shorter than previously found in tertiary care settings. In accordance with other longitudinal studies, those patients spent much more time depressed than manic., (2009 Elsevier B.V. All rights reserved.)

Background: The epidemiology of rapid-cycling bipolar disorder in the community is largely unknown., Aims: To investigate the epidemiological characteristics of rapid-cycling and non-rapid-cycling bipolar disorder in a large cross-national community sample., Method: The Composite International Diagnostic Interview (CIDI version 3.0) was used to examine the prevalence, severity, comorbidity, impairment, suicidality, sociodemographics, childhood adversity and treatment of rapid-cycling and non-rapid-cycling bipolar disorder in ten countries (n = 54 257)., Results: The 12-month prevalence of rapid-cycling bipolar disorder was 0.3%. Roughly a third and two-fifths of participants with lifetime and 12-month bipolar disorder respectively met criteria for rapid cycling. Compared with the non-rapid-cycling, rapid-cycling bipolar disorder was associated with younger age at onset, higher persistence, more severe depressive symptoms, greater impairment from depressive symptoms, more out-of-role days from mania/hypomania, more anxiety disorders and an increased likelihood of using health services. Associations regarding childhood, family and other sociodemographic correlates were less clear cut., Conclusions: The community epidemiological profile of rapid-cycling bipolar disorder confirms most but not all current clinically based knowledge about the illness.

Objectives: To evaluate the impact of Eating Disorders (EDs) lifetime co-morbidity among female with Bipolar Disorders (BDs) and to compare clinical and cognitive features among EDs subgroups., Method: A hundred and forty eight women with a lifetime history of Diagnostic and Statistical Manual, Fourth Edition (DSM-IV)-defined Bipolar-I, Bipolar-II and/or Cyclothymia, were consecutively enrolled to determinate the prevalence of co-morbid DSM-IV-defined Anorexia Nervosa [AN], Bulimia Nervosa [BN] or Binge Eating Disorder [BED]. Measures included the Structured Clinical Interview for the DSM-IV Axis I Disorders (SCID-I), the Clinical Global Impression (CGI) rating scale, the Eating Disorder Examination Questionnaire (EDE-Q) and BMI record., Results: Forty six patients (31%) reported lifetime history of at least one ED: AN was the most common ED (n=23, 15.5%), followed by BED (n=21, 14.2%), and BN (n=8, 5.4%); 6 patients (4.1%) reported multiple lifetime EDs. As expected, BMI was highest in BED patients and lowest in those with AN. Clinical characteristics were similar in the 3 groups, while rapid cycling and co-morbid drug abuse were more common in BED compared to AN or No-ED group. As expected cognitive eating symptoms assessed by the EDE-Q were all more represented in AN than in No-ED patients. AN and BED only differed in restricting behavior and weight concerns., Conclusions: Our results prompt for the recognition of co-morbid EDs among bipolar patients, indicating that BED, along with other EDs, may influence in different ways both clinical characteristics and course of the illness. Further perspective studies are necessary to better define the relationships between different EDs and Bipolar Spectrum disorders., (2009 Elsevier B.V. All rights reserved.)

Background: Early age at onset of bipolar disorder is clinically important since it predicts a more severe course of illness and a poorer prognosis. Recently the age at onset (AAO) of bipolar disorder (BPD) has been reported different in samples from the USA and Europe (Bipolar Collaborative Network). We have examined the AAO of first major affective episode in major depressive disorder (MDD) and bipolar disorder in a sample of patients consecutively admitted to an affective ward in Norway. We also examined the relation between AAO and affective temperaments., Methods: Semi-structured interview of 119 patients consecutively admitted to an affective ward. Patients were diagnosed according to DSM-IV criteria for major affective disorders and affective temperaments were assessed using Akiskal Mallya criteria., Results: Childhood-onset of BPD (before age 13) was found in 13.5% of patients, and early onset BPD (before age 20) in 61.6%. The AAO of first major affective disorder was significantly higher in MDD (n=67) compared to BPD (n=52); (28 Years Median (Min 10-Max 57) vs. 18 Years Median (Min 8-Max 41), p<0.001, Mann-Whitney U). Comparing patients with and without affective temperaments, showed that patients with such temperaments had an earlier AAO in both MDD and BPD (MDD: 20 Years Median (Min 10-Max 56), vs. 30 Years Median (Min 12-Max 57) p=0.006, Mann-Whitney U); BPD: 16 Years Median (Min 8-Max 30) vs. 20 Years Median (Min 12-Max 41, p=0.011, Mann-Whitney U)., Conclusion: Our Norwegian data are more in line with the US than the European data regarding age at onset of bipolar disorders. The presence of an affective temperament presents an additional affirmation of the early occurrence of mood symptoms in early onset forms of both MDD and BPD.

Background: Much of the literature has described personality disorder constructs for heroin addicts. Building on previous work we examine the relevance of affective temperament measures in these patients., Methods: 59 consecutive stabilized methadone treated heroin addicts, 34 with and 25 without psychiatric comorbidity, were compared, regarding affective temperaments, according to the Akiskal and Mallya formulation, with 58 healthy volunteers sharing similar social and regional demographics., Results: No differences were observed between heroin addicts and controls on either depressive or hyperthymic scales. Significant discrepancies were noted in cyclothymic and irritability scales, on which heroin addicts scored higher, regardless of the presence or absence of a dual diagnosis. In a multivariate discriminant analysis, mainly cyclothymic, and (to a lesser extent) irritable traits show a distinction between heroin addicts and controls, but not between heroin addicts with and without dual diagnoses., Limitation: Cross-sectional study., Conclusion: Our data suggest a new hypothesis. Cyclothymic, and to a lesser extent irritable traits (the "dark side"), could represent the temperamental profile of heroin addicts, largely irrespective of comorbidity, and tend to cohere with previous conceptualizations hypothesizing "sensation-seeking" (and "novelty-seeking") as the main personality characteristics of addiction.

Introduction: Bipolar disorder patients (BP) with comorbid Substance Use Disorder (SUD) may present clinical features that could compromise adherence and response to pharmacological treatment. The purpose of this study was to examine clinical and psychopathological features of BP with and without comorbid SUD in a real-world setting., Methods: The sample was composed by 131 affective patients. Sixty-five patients were affected by Bipolar Disorder I (BP-I, 49.2%), 29 by Bipolar Disorder II (BP-II, 22.3%) and 37 by Cyclothymic Disorder (CtD, 28.5%), according to DSM-IV. Sixty-six patients were diagnosed for a comorbid SUD. All patients have been submitted to psychometric assessment with Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HARS), Young Mania Rating Scale (YMRS), Global Assessment Scale (GAS), Social Adjustment Self-reported Scale (SASS), Quality of Life Scale (QoL), at baseline and repeated follow-up periods (1, 3, 6, 12 months)., Results: BP comorbid for SUD were more likely diagnosed as BP-II and CtD and were less likely to present a moderate-severe manic symptomatology. Furthermore, personality disorders were more frequent in SUD patients than in non-comorbid BP. BP with SUD were not different for primary outcome measure (HDRS, HARS, YMRS, GAS) from non-comorbid BP; however, BP with SUD were significantly more impaired in social functioning (SASS) at any stage of the follow-up and poor functioning increased the risk of relapse in substance use during treatment. Finally, SUD comorbidity did not represent a risk factor for treatment drop-out, while in our sample young age, low treatment dosage and BP-I diagnosis were significantly associated with drop-out., Discussion: The primary finding of this work is that BP with comorbid SUD are significantly more compromised in social functioning. Second, these patients were less likely to be diagnosed for BP-I and to present a severe manic symptomatology. Finally, we found that the diagnosis of SUD, but young age, low treatment dosage and BP-I diagnosis to be risk factors for treatment drop-out. Physicians should be alert to these differences in their clinical practice.

Background: Darrier's disease is a rare genodermatosis with a dominant autosomic penetrating variable transmission. The association between Darier's disease and neuropsychiatric disorders has been reported since 1996. Moreover, associations with mental retardation, schizophrenia, mood disorders and suicide have been reported. The discovery in 1999 of the ATP2A2 gene of Darier's disease, localised on chromosome 12, allowed significant advances notably in understanding the pathogenicity of these symptoms., Material and Methods: In this article, we present the preliminary results of a clinical and genetic study of eight Tunisian families, involving dermatologists, psychiatrists and geneticians. Eight patients with Darier's disease and their first degree relatives were included in the study after they had given their written consent. Thirty-five subjects were examined, 23 of them had Darier's disease. All patients were submitted to a complete clinical examination; notably dermatological screening, genetic inquiry and blood tests for haplotype analysis. Only 13 of them underwent a psychiatric examination., Results: The psychiatric examination was carried out only in 13 patients with Darier's disease, who revealed neuropsychiatric symptoms with a frequency of 61.1% (8/13). Two patients presented mild mental retardation; six patients had mood disorders, three of them belonged to the same family (two had recurrent depression, four belonged to the bipolar spectrum [2 bipolar disorder type 2, 2 cyclothymia]). The coexpression of the two distinct phenotypes (Darier's disease and bipolar disease), within the same three members' of the family of our study, suggests the existence of a genetic linkage between the two diseases, as has been reported in the literature.
