Proposed multidimensional structure of mania: beyond the euphoric-dysphoric dichotomy.

BACKGROUND: Although the construct of depression has been subjected to numerous factor analytic studies and phenomenological subtypes of clinical relevance have been delineated, this is not the case for mania. The few available studies have reported at least two factors, which consist of euphoric versus dysphoric-hostile subtypes. Our objective was to replicate and further enrich this literature. METHODS: In the EPIMAN French National Study we systematically evaluated 104 DSM-IV hospitalized manic patients in four university centers in different regions of France. Psychiatrists completed the Beigel-Murphy Manic State Rating Scale (MSRS), as well as the HAM-D(17), affective temperament scales, and the GAF Axis V from DSM-IV. Categorization of patients into pure versus dysphoric mania was made on the basis of clinical diagnosis, independent from psychometric measures. RESULTS: On principal component analysis of the MSRS, three factors explained the largest variance: a global manic (23.3% variance), paranoid-hostile (14.8% variance), and psychotic (9.1% variance). After varimax rotation, we obtained seven independent factors: F1 Disinhibition-instability, F2 Paranoia-hostility, F3 Deficit, F4 Grandiosity-psychosis, F5 Elation-euphoria, F6 Depression, and F7 (Hyper)sexuality. We could not demonstrate significant correlations between the individual factors and impaired functioning on GAF. However, depressive and, to some extent, cyclothymic temperaments correlated with F6 Depression. Finally, intergroup comparisons between pure versus dysphoric mania diagnosed clinically showed high levels of F3 Deficit and F5 Elation in the pure, and of F6 Depression in dysphoric, mania; F2 Paranoia-hostility did not discriminate these two clinical forms of mania. LIMITATIONS: Although the present analyses on the Beigel-Murphy represent the largest sample studied to date, they are still underpowered and do not guarantee a stable factorial structure. Our findings are cross-sectional and require prospective validation. CONCLUSIONS: Our data suggest that 'dysphoria' as used in the literature to qualify mania is insufficiently precise, and is best further specified as 'depressive' versus 'irritable.' Moreover, our data extend the rich multidimensional phenomenology of mania beyond the existing literature: we submit that disinhibition-instability (a core 'activation' component) can, on the one hand, be associated with distinct emotional presentations (euphoric, depressive, or irritable-hostile), as well as psychotic and deficit symptomatology on the other.

Cyclothymic OCD: a distinct form?

BACKGROUND: Clinical research on the comorbidity of obsessive compulsive disorder (OCD) and other anxiety disorders has largely focused on depression. However in practice, resistant or severe OCD patients not infrequently suffer from a masked or hidden comorbid bipolar disorder. METHOD: The rate of bipolar comorbidity in OCD was systematically explored among 453 members of the French Association of patients suffering from OCD (AFTOC) as well as a psychiatric sample of OCD out-patients (n=175). As previous research by us has shown the epidemiologic and clinical sample to be similar, we combined them in the present analyses (n=628). To assess mood disorder comorbidity, we used structured self-rated questionnaires for major depression, hypomania and mania (DSM-IV criteria), self-rated Angst's checklist of Hypomania and that for the Cyclothymic Temperament (French version developed by Akiskal and Hantouche). RESULTS: According to DSM-IV definitions of hypomania/mania, 11% of the total combined sample was classified as bipolar (3% BP-I and 8% BP-II). When dimensionally rated, 30% obtained a cut-off score >/=10 on the Hypomania checklist and 50% were classified as cyclothymic. Comparative analyses were conducted between OCD with (n=302) versus without cyclothymia (n=272). In contrast to non-cyclothymics, the cyclothymic OCD patients were characterized by more severe OCD syndromes (higher frequencies of aggressive, impulsive, religious and sexual obsessions, compulsions of control, hoarding, repetition); more episodic course; greater rates of manic/hypomanic and major depressive episodes (with higher intensity and recurrence) associated with higher rates of suicide attempts and psychiatric admissions; and finally, a less favorable response to anti-OCD antidepressants and elevated rate of mood switching with aggressive behavior. LIMITATION: Hypomania and cyclothymia were not confirmed by diagnostic interview by a clinician. CONCLUSION: Our data extend previous research on "OCD-bipolar comorbidity" as a highly prevalent and largely under-recognized and untreated class of OCD patients. Furthermore, our data suggest that "cyclothymic OCD" could represent a distinct form of OCD. More attention should be paid to it in research and clinical practice.

[Cyclothymic obsessive-compulsive disorder. Clinical characteristics of a neglected and under-recognized entity].

OBJECTIVE: Clinical research is largely focused on depressive comorbidity in obsessional compulsive disorder (OCD). However some recent publications have suggested that bipolar comorbidity occurs in authentic OCD and its presence has a differential impact on the clinical picture and course of OCD. METHOD: Recent data from the collaborative survey conducted with AFTOC (French Association of patients suffering from OCD) have revealed a high rate of bipolar comorbidity in OCD: 30% for hypomania and 50% for cyclothymia. RESULTS: The present paper presents further comparative analyses between OCD with (n = 302) versus without cyclothymia (n = 272). The sub-group "Cyclothymic OCD" is characterized by a different clinical picture (higher frequency of aggressive, impulsive, religious and sexual obsessions, and compulsions of control, hoarding, repetition), episodic course, higher rate of major depressive episodes (with more intensity and recurrence) associated with higher rates of suicide attempts and psychiatric admissions, and less favorable response to anti-OCD treatments. CONCLUSION: These data suggested that cyclothymic OCD could represent a specific distinct variant form of OCD. More vigilance is needed toward this entity which is largely under-recognized in clinical practice.

[Obsessive-compulsive disorder in children induced by streptococcal infection].

FROM OBSESSIVE-COMPULSIVE DISORDER TO PANDAS: Obsessive-compulsive disorder (OCD) represents a potentially severe and handicapping disorder that affects several hundreds of thousands of children in France. OCD has, for many years, been considered as a neurosis resulting from mental conflicts. It is currently seen as a neurobiological disorder, the etiological substratum of which is more organic than mental. Recently a sub-type of OCD was isolated in children following infection by Group A b-hemolytic streptococci. This sub-type has been described as Paediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections (PANDAS). A NEW PHYSIOPATHOLOGICAL APPROACH: The putative dysimmune relationship between bacterial infection and neurotic disorder has led to the development of an original etiopathogenic model that may lead to new therapeutic strategies. The clinical case report of an adolescent presenting with trichotillomania associated with recurrent pharyngitis is a good illustration of this. PUBLISHED DATA: Data published in medical literature over the last 10 years indicates a 10% prevalence in the young suffering from OCD, i.e. 0.1 to 0.3% of the young population.

Toward a refined phenomenology of mania: combining clinician-assessment and self-report in the French EPIMAN study.

BACKGROUND: Because manic patients lack insight, they are generally considered unreliable observers of their own psychopathology. The present analyses sought to examine to what extent patient reports could improve formal diagnostic criteria for mania--and be validated against the Carroll-Klein (CK) psychobiological model of bipolarity. METHOD: 104 DSM-IV acutely manic (hospitalized) patients provided self-assessment on the Ahearn--Carroll scale, the Multiple Visual Analogue Scales of Bipolarity (MVAS-BP). A principal component analysis (PCA) was performed on MVAS-BP, and the data on factorial scores were then compared to dimensional scores according to the CK model and to factors on the Beigel-Murphy Manic State Rating Scale (MSRS) completed by psychiatrists. RESULTS: The PCA identified a general factor accounting for 33% of the total variance; after varimax rotation, seven independent factors emerged, essentially in coherence with the signs and symptoms of DSM-IV mania, except for the 'social disinhibition' factor, which does not figure out as a distinct criterion in DSM-IV. Strong correlations were obtained (r > or = 0.80) between the four major factors of MVAS-BP and the four dimensional categories of the CK model: 'Consummatory Reward' with F1 'Elation and Inflated Self-esteem' (r=0.93), 'Incentive Reward' with F2 'Activation' (r=0.84), 'Psychomotor Pressure' with F3 'Acceleration' (r=0.85), and 'Central Pain' with F4 'Anxiety-Depression' (r=0.84). The F2 'Activation' appeared to be strongly correlated (r > or = 0.70) to all categories of the CK model. Correlational analysis between the factor structure of MVAS-BP and the MSRS showed significant coefficients on the scores assessing the emotional factors of 'Elation' and 'Depression.' Among the MVAS-BP factors, only 'Activation' was correlated to the majority of clinician ratings as obtained by the MSRS. CONCLUSIONS: These findings provide overall construct validity to the DSM-IV criteria for mania. Self-assessment of this disorder appears feasible and potentially useful in practice; lack of insight, poor judgment, and distractibility obviously require assessment by a clinician. Although our data are correlational and require prospective validation, they nonetheless suggest that (1) activation should be raised to the status of the stem criterion for mania, (2) to specify mood as elated, depressive, anxious, or irritable, and (3) to give individual status to social disinhibition (indiscriminate gregariousness) as a core pathological behavior in mania. Combining clinician- and self-observation thus produces a more precise and complete phenomenology of mania. We finally submit that the foregoing reformulation provides a psychobiological basis to the manic construct as formulated in the Carroll-Klein model.

The feasibility of self-assessment of dysphoric mania in the French national EPIMAN study.

BACKGROUND: There is presently considerable uncertainty on how to best assess mixed mania. The present contribution explores the feasibility of discriminating manic and dysphoric manic states on the basis of self-rating in the acute phase of the illness. METHODS: In the French four-site national EPIMAN study of 104 patients devoted to the clinical evaluation and subclassification of mania, we used the Multiple Visual Analog Scales of Bipolarity (MVAS-BP, 26 items) of Ahearn-Carroll in a self-assessment format. The study was conducted on consecutive patients hospitalized for an acute DSM-IV mania. The severity of mania was measured by the Beigel-Murphy scale (MSRS) assessed by psychiatrists. When mania abated, temperaments according to Akiskal and Mallya were administered in their French version. RESULTS: Principal component analysis revealed a general factor explaining 33% of the variance and, after rotation, seven factors defining different dimensions of the phenomenology of mania. The factorial scores, as well as the dimensional scores of the Carrol-Klein model significantly distinguished pure versus dysphoric mania made on clinical grounds. Gender seemed to influence two factors: high 'anxious-depressive' score in females (which is in line with female overrepresentation in mixed mania), vs. high score in males on the 'gregariousness' factor (which represents social disinhibition of the hyperthymic temperament known to be more prevalent in men). LIMITATION: Cross-sectional correlational study in need of longitudinal validation. CONCLUSIONS: EPIMAN data deriving from a national clinical population showed the feasiblity and face validity of self-assessment in acute mania, in particular its dysphoric subtype. Temperament in women seemed to contribute to the genesis of mixed (dysphoric) mania in accordance with Akiskal's hypothesis of opposition of temperament and polarity of bipolar episodes in mixed states. Self-assessment was capable of capturing accurately the subthreshold depressive symptomatology of mixed mania, which can be missed in hetero-evaluation by hasty clinical interview.

Obsessive-compulsive disorder: evaluation of clinical and biological circadian parameters during fluoxetine treatment.

RATIONALE: Many biological abnormalities have been found in obsessive-compulsive disorder (OCD). The circadian rhythm investigations of different clinical and biological parameters may provide a comparison with depression. Fluoxetine is one of the efficient drugs in alleviating symptoms of OCD. The effect of fluoxetine can highlight some clues to the neurotransmitter alterations in the disorder. OBJECTIVE: The present study investigated clinical and biological circadian modifications in OCD patients during a fluoxetine treatment. METHODS: Daily clinical symptoms, and circadian rhythms of axillary temperature, plasma cortisol and plasma melatonin were assessed in eight patients suffering from OCD. These parameters were compared in the same patients, before and after an 8-week fluoxetine treatment period. RESULTS: A therapeutic effect of fluoxetine was obtained. No significant differences were observed either in daily clinical variations or in biological circadian rhythms measured before and after treatment. CONCLUSION: The therapeutic efficacy of fluoxetine was not related to the biological parameters assessed.

Systematic clinical methodology for validating bipolar-II disorder: data in mid-stream from a French national multi-site study (EPIDEP).

BACKGROUND: This paper presents the methodology and clinical data in mid-stream from a French multi-center study (EPIDEP) in progress on a national sample of patients with DSM-IV major depressive episode (MDE). The aim of EPIDEP is to show the feasibility of validating the spectrum of soft bipolar disorders by practising clinicians. In this report, we focus on bipolar II (BP-II). METHOD: EPIDEP involves training 48 French psychiatrists in 15 sites; construction of a common protocol based on the criteria of DSM-IV and Akiskal (Soft Bipolarity), as well as criteria modified from the work of Angst (Hypomania Checklist), the Ahearn-Carroll Bipolarity Scale, HAM-D and Rosenthal Atypical Depression Scale; Semi-Structured Interview for Evaluation of Affective Temperaments (based on Akiskal-Mallya), self-rated Cyclothymia Scale (Akiskal), family history (Research Diagnostic Criteria); and prospective follow-up. RESULTS: Results are presented on 250 (of the 537) MDE patients studied thus far during the acute phase. The rate of BP-II disorder which was 22% at initial evaluation, nearly doubled (40%) by systematic evaluation. As expected from the selection of MDE by uniform criteria, inter-group comparison between BP-II vs unipolar showed no differences on the majority of socio-demographic parameters, clinical presentation and global intensity of depression. Despite such uniformity, key characteristics significantly differentiated BP-II from unipolar: younger age at onset of first depression, higher frequency of suicidal thoughts and hypersomnia during index episode, higher scores on Hypomania Checklist and cyclothymic and irritable temperaments, and higher switching rate under current treatment. Eighty-eight percent of cases assigned to cyclothymic temperament by clinicians (with a cut-off of 10/21 items on self-rated cyclothymia) were recognized as BP-II. Evaluation of this temperament by clinician and patient correlated at a highly significant level (r=0.73; p <0.0001). Cyclothymia and hypomania were also correlated significantly (r=0.51; p < 0.001). LIMITATION: In a study conducted in diverse clinical settings, it was not possible to assure that clinicians making affective diagnoses were blind to the various temperamental measures. However, bias was minimized by the systematic and/or semi-structured nature of all evaluations. CONCLUSION: With a systematic search for hypomania, 40% of major depressive episodes were classified as BP-II, of which only half were known to the clinicians at study entry. Cyclothymic temperamental dysregulation emerged as a robust clinical marker of BP-II disorder. These data indicate that clinicians in diverse practice settings can be trained to recognize soft bipolarity, leading to changes in diagnostic practice at a national level.

Gender, temperament, and the clinical picture in dysphoric mixed mania: findings from a French national study (EPIMAN).

BACKGROUND: This research derives from the French national multisite collaborative study on the clinical epidemiology of mania (EPIMAN). Our aim is to establish the validity of dysphoric mania along a "spectrum of mixity" extending into mixed mania with subthreshold depressive manifestations; to demonstrate the feasibility of obtaining clinically meaningful data on this entity on a national level; and to characterize the contribution of temperamental attributes and gender in its origin. METHODS: EPIMAN involves training 23 French psychiatrists in four different sites, representing four regions of France; to rigorously apply a common protocol deriving from the criteria of DSM-IV and McElroy et al.; the use of such instruments as the Beigel-Murphy, Ahearn-Carroll, modified HAM-D; and measures of affective temperaments based on the Akiskal-Mallya criteria; obtaining data on comorbidity, and family history (according to Winokur's approach as incorporated into the FH-RDC); and prospective follow-up for at least 12 months. The present report concerns the clinical and temperamental features of 104 manic patients during the acute hospital phase. RESULTS: Dysphoric mania (DM defined conservatively with fullblown depressive admixtures of five or more symptoms) occurred in 6.7%; the rate of dysphoric mania defined broadly (DM, presence of > or = 2 depressive symptoms) was 37%. Depressed mood and suicidal thoughts had the best positive predictive values for mixed mania. In comparison to pure mania (0-1 depressive symptoms), DM was characterized by female over-representation; lower frequency of such typical manic symptomatology as elation, grandiosity, and excessive involvement; higher prevalence of associated psychotic features; higher rate of mixed states in first episodes; and complex temperamental dysregulation along primarily depressive, but also cyclothymic, and irritable dimensions; such irritability was particularly apparent in mixed mania at the lowest threshold of depressive admixtures of two symptoms only. LIMITATION: In a study involving hospitalized affectively unstable psychotic patients, it was difficult to assure that psychiatrists making the clinical diagnoses would be blind to the temperamental measures. However, bias was minimized by the systematic and/or semi-structured nature of all evaluations. CONCLUSIONS: Mixed mania, defined cross-sectionally by the simultaneous presence of at least two depressive symptoms, represents a prevalent and clinically distinct form of mania. Subthreshold depressive admixtures with mania actually appear to represent the more common expression of dysphoric mania. Moreover, an irritable dimension appears to be relevant to the definition of the expression of mixed mania with the lowest threshold of depressive symptoms. Neither an extreme, nor an endstage of mania, "mixity" is best conceptualized as intrusion of mania into its "opposite" temperament - especially that defined by lifelong depressive traits - and favored by female gender. These data suggest that reversal from a temperament to an episode of "opposite" polarity represents a fundamental aspect of the dysregulation that characterizes bipolar disorder. In both men and women with hyperthymic temperament, there appears "protection" against depressive symptom formation during a manic episode which, accordingly, remains relatively "pure". Because men have higher rates of this temperament, pure mania is overrepresented in men; on the other hand, the depressive temperament in manic women seems to be a clinical marker for the well-known female tendency for depression, hence the higher prevalence of mixed mania in women.

Recent clinical trials of hydroxyzine in generalized anxiety disorder.

Numerous clinical trials in the 1960s and 1970s have attested to the anxiolytic efficacy of hydroxyzine and its beneficial effect on sleep, as well as in reducing stress and anxiety associated with coronary disease. Experience with hydroxyzine has also shown a lack of organ toxicity and an absence of dependency. Recent controlled clinical trials with hydroxyzine have confirmed its efficacy (at a fixed dose of 50 mg) in generalized anxiety disorder--superiority over placebo on all anxiety measures from the first week with early target symptoms which are grouped in a cognitive component of anxiety. Efficacy was maintained throughout the 4 weeks of treatment and after abrupt discontinuation. In another controlled trial vs. lorazepam, hydroxyzine demonstrated greater and more rapid cognitive improvement.

[Tools for clinical evaluation of affective temperaments].

The authors argue from an "adult" perspective, that clinically ascertained affective dysregulations are prevalent in the prebipolar history. This hypothesis is based: 1) on early age of onset; 2) gender ratio; 3) high propensity to mood switching under antidepressant treatment; 4) high rate of recurrence; 5) family affective loading and; 6) the frequent superposition of major episodes on affective temperamental dysregulation (prominence of mood lability and explosive anger: indicators of mixed states). The authors submit that affective temperaments (cyclothymic, hyperthymic and dysthymic) represent putative developmental pathways to bipolarity. A french version of the semi-structured interview and self-assessment of affective temperaments had been constructed by the authors. The french version of these psychometric tools is presented in this chapter. The authors hoped that current knowledge and new research in the domain of affective temperaments will encourage clinicians to further understanding the manic-depressive illness and to make early detection of different clinical expressions of bipolarity. More clinical sophistication is needed to go beyond the classical "diagnostic" instruments and artificial classifications (as in DSM IV) and to delineate the psycho-biological pathways to bipolarity.

[Modern typology of symptoms and obsessive-compulsive syndromes: results of a large French study of 615 patients].

OBJECTIVES: The most common strategy to search for homogenous subgroups of Obsessive-Compulsive Disorder (OCD) patients has been based on the OCD symptoms themselves as a classifying variables. The purpose of this study was to: expand recognition of major clinical OCD subtypes in a large cohort of patients recruited from the national french survey: "Screening-Understanding-Treating OCD"; reproduce preliminary data coming from a US collaborative study on OCD sub-types [Baer L, J Clin Psychiatry, 1994; 55 (3):18-23]. METHOD: From 731 OCD/OCS (OC disorder or syndromes) patients recruited in the phase 1 of the national french survey, complete collected data on the Y-BOCS Symptom Checklist (YBOCS-CL) were obtained in 615 patients and on the OCD spectrum inventory in 646 patients. Principal components analysis (PCA) was firstly applied on major symptom categories of the YBOCS-CL, and next on each individual symptom. Gender effect on clinical aspects of OCD was also explored by comparative descriptive analysis. RESULTS: The first PCA on major symptoms categories confirmed the grouping of all categories in three major factors, named as following: Facteur 1 = "Predominantly Compulsive" (loaded with items of symmetry, order, hoarding, repeting, counting, checking); Facteur 2 = "Predominantly Obsessive" (loaded with aggression, violent, religious, sexual obsessions) and Facteur 3 = "Mixed" (with contamination and somatic obsessions and washing compulsions). Our data seemed to be very close to US collaborative study that had found in a sample of 107 OCD patients, the presence of the same three major clinical factors. The second PCA applied on all YBOCS-CL individual items had provided interesting items groupings, suggesting a reorganization and re-labelling of YBOCS-CL symptoms categories. Therefore, a new presentation of the YBOCS-CL can be proposed with a more clinical relevance than the original version. Results from OC spectrum inventory showed high comorbidity rate with many of OCD related disorders. Finally, a gender influence on OC clinical manifestations was observed, especially more severity and higher rate of difficult OC-subtypes in male patients. The french national survey data on OC symptoms sub-typing and clustering showed a "natural" groupings of OC symptom categories which add more validity to the subtypes proposed by ICD-10 (based on syndromal predominance : obsessions, compulsions or mixed). These sub-categories are not part of the DSM III-R, neither of the new version of DSM IV!

[Obsessive-compulsive disorders versus obsessive-compulsive syndromes. Comparative study of two surveys of the general population and of psychiatric consultants].

Recent epidemiological studies were conducted in the general population, showing high rate prevalence of obsessive-compulsive disorder (OCD), estimated between 2 and 3% in the community. Although investigation of OCD prevalence had challenged the "real" definition of diagnostic threshold-criteria. Recent data from the Zurich study and from a large french clinical survey had confirmed the high prevalence and the validity of the subsyndromal forms of OCD (which are labelled as OCS or Obsessive-Compulsive Syndroms). In the Zurich study, lifetime prevalence rates of OCS was estimated to 5.5%. Point prevalence rates of OCS was recorded at 19.2% in the French survey (population of 4364 new patients seeking psychiatric help). In the two studies, a significant association between OCS and other disorders (major depression, dysthymia, phobic disorders) was found. Lifetime suicide attempts rate was found in 16-18% of subjects suffering from OCS (respectively in the Zurich and the French studies). These results confirmed that OCS (or subsyndromal forms of OCD) seemed to represent a clinically valid subgroup which modern classification systems fail to recognize, requiring treatment.

[Prospective follow-up over a 12 month period of a cohort of 155 patients with obsessive-compulsive disorder: phase III National DRT-TOC Study].

In the phase III of the french national study on OCD, 155 patients suffering from an OCD (full DSM III-R criteria, score on NIMH-OC > or = 7, not treated or undertreated) had entered a naturalistic follow-up of 12 months duration. Obsessions, compulsions, depression, anxiety, impulsivity and global functioning were assessed by using NIMH-OC, CPRS-OC2, MOCI, MADRS, HAD (-A, -D), BDS (Behavioral Dyscontrol Scale), CGI and GAS (DSM III-R). From the initial population (155 patients), 130 (84%) had been treated with drugs and were "completers" and assessed at M6 and M12; 18 (11.6%) were lost to follow-up and 7 (4.5%) had dropped out because of treatment refusal, side-effect or improvement. Only 19% of patients had received a behavior therapy. In spite of selection of patients with severe and chronic OCD associated to depression (mean MADRS score = 25), 85% of treated patients had been treated with one anti-OCD drug (105 with fluoxetine, 17 with clomipramine and 17 with other antidepressants), 4.5% needed a treatment substitution and 4.5% a bitherapy (combination of 2 anti-OCD drugs); 84% of patients were considered as "good compliant" with visit agenda and treatment. At the end of follow-up, global improvement was observed in 77% of patients treated. Clinical improvement was assessed by different response criteria (final NIMH-OC score, 30% decrease on NIMH-OC, 35% decrease on MOCI, final GAF score > or = 70) which showed 4 patterns of response to treatment: "positive response on M6 and M12" = 43-64%; "only M12" (slow response) = 13-24%; "only M6" (escape or relapse) = 4-6%; "negative response on M6 and M12" (resistant OCD) = 19-33%. During 12 month treatment, 31 patients (22.5%) had presented an adverse effect in which 7 cases (5.1%) with "serious adverse event" and 5 cases (3.6%) who required treatment drop-out. Predictive factors of clinical response to anti-OCD drugs were explored: 1) "lack of insight" was the best factor to characterise the resistant group; 2) high base-line of "impulsivity" predict better response at M6; 3) important to severe slowness was associated with a longer delay to response (between M6 and M12). The results of the phase III from the french multi-site study will be compared to the international data on long-term treatment of OCD.

[Frequency and clinical aspects of bipolar II disorder in a French multicenter study: EPIDEP].

This paper presents the definite data from a French multi-center study (EPIDEP). The aim of EPIDEP was to show the feasibility of validating the spectrum of soft bipolar disorders by practicing clinicians. In this report we focus on data concerning the frequency of BP-II disorder and the key characteristics of BP-II by systematic comparison versus Unipolar depression. EPIDEP involved training 48 french psychiatrists in 15 sites; it is based on a common protocol following the DSM IV criteria (Semi-Structured Interview for Hypomania and Major Depression), and Akiskal (Soft Bipolarity), as well as criteria modified from the work of Angst (Hypomania Checklist), the Ahearn-Carroll Bipolarity Scale, HAM-D and Rosenthal Atypical Depression Scale; Semi-Structured Interview for Affective Temperaments (based on Akiskal-Mallya), self-rated Cyclothymia Scale (Akiskal). Comorbidity and family history (Research Diagnostic Criteria) were also obtained; EPIDEP was globally scheduled in two phases: Phase 1 devoted to recruiting major depressives, and phase 2 involved in more sophisticated assessment of soft bipolarity and administrating related measures. Results are presented on the total of 537 patients included at "visit 1" and 493 assessed for soft bipolarity at "visit 2". The BP-II global rate which was 21.7% at initial evaluation, nearly doubled (39.8%) by systematic evaluation of hypomania. Intergroup comparison versus unipolar depressives showed the following key characteristics of BP-II disorder: 1) distinct clinical presentation at index depressive episode despite uniformity in global intensity of depression (overrepresentation in BP-II of "suicidal thoughts", "guilt feelings", "depersonalisation-derealisation", "hypersomnia" "and weight gain"; and of "psychic anxiety" and "initial insomnia" in UP); 2) different course of illness with younger age of onset of first depression, higher rate of suicidal attempts, recurrency and hospitalisations; 3) more difficulties for recognition of the correct diagnosis; 4) more complex temperamental dysregulations (mixture of cyclothymic, hyperthymic and irritable traits which are highly represented in BP-II group); 5) higher rate in family history of mental disorders, especially bipolar disorders. Finally, EPIDEP data confirmed the diagnostic reliability of self-rating of hypomania and cyclothymia. With a systematic search of hypomania, almost 40% of major depressive episodes seen in psychiatric settings were classified as BP-II, of which only half were recognized by the clinicians at study inclusion. The BP-II validity as a distinct disorder from Unipolars was confirmed. Moreover, EPIDEP emphasized the reliability of self-rating in assessing soft-bipolarity (hypomania and cyclothymia). In total, EPIDEP data indicated that recognition of BP-II is feasible in diverse practice settings and proposed for clinicians some adapted clinical tools for assessing soft bipolarity.

[Bipolar obsessive-compulsive disorder: confirmation of results of the "ABC-OCD" survey in 2 populations of patient members versus non-members of an association].

Clinical data are largely focused on depressive comorbidity in OCD. However in practice, treating resistant or severe OCD sufferers revealed many cases who seem to have an authentic OCD with a hidden comorbid bipolar disorder. Most reports had evaluated the OCD comorbidity in unipolar and bipolar mood disorders (Kruger et al., 1995; Chen et Dilsaver, 1995). The only investigation in clinical population focused on the reverse issue was conducted in Pisa. Perugi et al. (1997) have showed in a consecutive series of 315 OCD outpatients, that 15.7% presented a bipolar comorbidity, mostly with BP-II disorder. Further analyses suggested that when comorbidity occurs with bipolar and unipolar depression, it has a differential impact on the clinical picture and course of OCD. The rate of bipolar comorbidity in OCD was analyzed in a recent epidemiological survey undertaken by the French Association of patients suffering from OCD (FA-OCD or AFTOC in French). In a sample of 453 OCD patients, 76% had suffered from a major depression, 11% from bipolar disorder (DSM IV mania or hypomania), 30% from hypomania (cases that obtained a score > or = 10 on the self-rated Angst Hypomania Checklist). According to the score > or = 10 on Self-rated Questionnaire for Cyclothymic Temperament, 50% were classified as cyclothymic. The self-assessment of soft-bipolar dimensions, such as hypomania and cyclothymia was previously validated in a multi-site study in major depression (Hantouche et al., 1998). Further analyses showed that comorbidity with soft bipolarity was characterized by significant interactions with high levels of impulsivity, anger attacks and suicidal behavior. In order to confirm these data, another cohort (n = 175 patients treated by psychiatrists for OCD) was formed and named "PSY-OCD". Comparative analyses between the two populations allowed showing very few demographic and clinical differences. The frequency rate of "bipolar OCD" was equivalent in both populations: BP-II disorder (DSM IV criteria) was present in 11% of FA-OCD and 16% of PSY-OCD. Furthermore using the Hypomania Checklist showed that BP-II disorder rate (score > or = 10) was higher: 32% of in both populations. Cyclothymic rate was also globally higher, but significant difference was obtained: 56% of FA-OCD versus 45% of PSY-OCD (p = 0.02). Moreover, mood switching rate under anti-OCD drugs was equivalent in both OCD populations (respectively 38% and 33%, p = ns). In case of BP comorbidity, patients had presented a greater number of concurrent major depressive episodes and suicidal attempts. When concurrent depression was considered, the rate diagnosis of soft bipolarity was 2.5 fold, and the number of suicidal attempts augmented by 7 fold (by comparison versus non-depressed OCD). Despite very early descriptions (since the beginning of the last century) of particular relationships between so-called "psychasthenia, folie de doute, folie raisonnante" and "circular and intermittent madness or cyclothymia", a few attention has been devoted to this complex pattern of comorbidity. The comparative data deriving from the collaborative survey with patients who are members of AFTOC and with a cohort of psychiatric outpatients, confirm the reality of bipolar-OCD comorbidity, which is largely under-recognized in clinical practice. More in depth analyses are now undertaken in order to investigate the characteristics of "bipolar OCD" by comparison to "non bipolar OCD".

[Behavior dyscontrol scale: validation and initial results].

The numerous recent trials devoted to disruptive behavior disorders indicate the renewed interest of clinicians for these so-called dimensions and call for revision of the instruments with which they are evaluated. The present paper provides a brief review of the currently used scales for rating impulsivity. A new scale for evaluating the behavioural dyscontrol is proposed. The items of this scale are selected a priori according to clinical experience with patients suffering from lack of behavioural control. The Behaviour Dyscontrol Scale (BDS) includes, in the initial version, 4 parts. The first part concerns the generalized lack of control (G-BDS). This is a questionnaire of 24 items. The second part is constituted by a questionnaire which lists a number of specific behaviours where impulsivity has a central role (S-BDS). Part III is constituted with 4 Visual Analogue Scales for evaluating handicap linked to dyscontrol. Part IV is constituted by 3 Visual Analogue Scales concerning the physician global impression about the lack of general control in cognitions, emotions and behaviours. For validation, 166 patients (111 females and 55 males), either hospitalized or ambulatory, and 35 controls (16 females and 19 males) were included in this study. Mean age of patients was 38.5 (SD = 10.5) years. The patients population is subdivided in 4 subgroups, anxious, depressed, abusers and bulimics according to DSM III-R criteria. Patients and controls global scores were significantly different at the G-BDS (p less than 10(-4)) and not at S-BDS.(ABSTRACT TRUNCATED AT 250 WORDS)

[Major agitated-anxious versus blunted-retarded depression: differential effects of fluoxetine].

A multi-centre study was designed to evaluate the efficacy and tolerance of fluoxetine in two groups of major depression: "agitated-anxious" and "blunted-retarded". The study included 50 patients presenting a major depressive episode (following DSM III-R criteria and score > or = 20 on MADRS): 26 in "agitated-anxious" group (score > or = 15 on Hamilton anxiety scale and > or = 10 on Tyrer anxiety brief scale) and 24 in the "blunted-retarded" group (score > or = 15 on Widlöcher retardation scale and > or = 10 on Abrams-Taylor blunted affect scale). After one week period on placebo, all patients were treated in an open design with fluoxetine at a fixed daily dose of 20 mg and followed on a period of 6 weeks with active treatment. In spite of a significant antidepressant efficacy of fluoxetine in the two groups, better results were observed in the "agitated-anxious" depressed group: marked improvement on MADRS total score at day 42 (76% decrease vs 62% in the "blunted-retarded" group, p = 0.012), greater number of "responders" defined by a decrease > or = 50% on MADRS total score and a total score < or = 12 (95% vs 63%, p = 0.04), better patient's global impression on efficacy (54% of "excellent efficacy" vs 18%, p = 0.012), more improvement on HSCL-58 total score (mean decrease of 69% vs 39%, p = 0.016), higher improvement on "hostility/interpersonal hypersensitivity" score (mean decrease of 74% vs 37%, p = 0.001) and on "anger attacks/irritability" sub-score (mean decrease of 73% vs 30%, p = 0.0002).(ABSTRACT TRUNCATED AT 250 WORDS)
