Abstract
Despite its inclusion as a distinct entity in APA's Diagnostic and Statistical Manual of Mental Disorders since 1994, bipolar II disorder remains a surprisingly neglected psychiatric condition. Understudied and underrecognized, bipolar II disorder is often misdiagnosed and misunderstood, even by experienced clinicians. As a result, patients typically experience symptoms for more than 10 years before receiving the correct diagnosis. Incorrect diagnosis leads to incorrect treatment, including overuse of monoaminergic antidepressant medications, with resultant declines in functioning and worse quality of life. Perhaps because of its underrecognition, treatment studies of bipolar II disorder are limited, and, too often, results of bipolar I disorder studies are applied to bipolar II disorder, with no direct evidence supporting this practice. Bipolar II disorder is an understudied and unmet treatment challenge in psychiatry. In this review, the authors provide a broad overview of bipolar II disorder, including differential diagnosis, course of illness, comorbid conditions, and suicide risk. The authors summarize treatment studies specific to bipolar II disorder, identifying gaps in the literature. This review reveals similarities between bipolar I and bipolar II disorders, including risks of suicide and predominance of depression over the course of illness, but also differences between the phenotypes in treatment response, for example, to antidepressant medications.

Abstract
OBJECTIVE A better understanding of the genetic, molecular and cellular mechanisms of brain-derived neurotrophic factor (BDNF) and its association with neuroplasticity could play a pivotal role in finding future therapeutic targets for novel drugs in major depressive disorder (MDD). Because there are conflicting results regarding the exact role of BDNF polymorphisms in MDD still, we set out to systematically review the current evidence regarding BDNF-related mutations in MDD. METHODS We conducted a keyword-guided search of the PubMed and Embase databases, using 'BDNF' or 'brain-derived neurotrophic factor' and 'major depressive disorder' and 'single-nucleotide polymorphism'. We included all publications in line with our exclusion and inclusion criteria that focused on BDNF-related mutations in the context of MDD. RESULTS Our search yielded 427 records in total. After screening and application of our eligibility criteria, 71 studies were included in final analysis. According to present overall scientific data, there is a possibly major pathophysiological role for BDNF neurotrophic systems to play in MDD. However, on the one hand, the synthesis of evidence makes clear that likely no overall association of BDNF-related mutations with MDD exists. On the other hand, it can be appreciated that solidifying evidence emerged on specific significant sub-conditions and stratifications based on various demographic, clinico-phenotypical and neuromorphological variables. CONCLUSIONS Further research should elucidate specific BDNF-MDD associations based on demographic, clinico-phenotypical and neuromorphological variables. Furthermore, biomarker approaches, specifically combinatory ones, involving BDNF should be further investigated.

Abstract
Attention-Deficit/Hyperactivity Disorder (ADHD), Bipolar Disorder (BD) and Alcohol Use Disorder (AUD) are common medical conditions often coexisting and exerting mutual influence on disease course and pharmacological treatment response. Each disorder, when considered separately, relies on different therapeutic approaches, making it crucial to detect the plausible association between them. Treating solely the emerging condition (e.g., alcoholism) and disregarding the patient's whole psychopathological ground often leads to treatment failure and relapse. Clinical experience and scientific evidence rather show that tailoring treatments for these three conditions considering their co-occurrence as a sole complex disorder yields more fulfilling and durable clinical outcomes. In light of the above considerations, the purpose of the present review is to critically discuss the pharmacological strategies in the personalized treatment of complex conditions defined by ADHD-bipolarityalcoholism coexistence.

Clinical and psychopathological correlates of duration of untreated illness (DUI) in affective spectrum disorders. Eur Neuropsychopharmacol 2022; 61:60-70. [PMID: 35810585 DOI: 10.1016/j.euroneuro.2022.06.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 06/10/2022] [Accepted: 06/11/2022] [Indexed: 11/23/2022]
Abstract
Affective disorders represent psychopathological entities lying on a continuum, characterized by high prevalence and functional impairment. A delay in treatment initiation might increase the burden associated with affective spectrum disorders. The present study was aimed at analyzing the correlates of a long duration of untreated illness (DUI) in these conditions. We recruited subjects diagnosed with affective disorders, both in- and outpatients, and collected information concerning socio-demographic, clinical, and psychopathological characteristics. Long DUI was defined according to previous research criteria as >2 years for Bipolar Disorders or >1 year for Depressive Disorders. Bivariate analyses were performed to compare subjects with a long and short DUI (p<0.05). A logistic regression was operated to evaluate the correlates of long DUI. In the present sample (n=135), 34.1% (n=46) subjects showed a long DUI. This subgroup presented with more physical comorbidities (p=0.003), higher body mass index (BMI) (p<0.001), more frequent anxiety onset (p=0.018), younger onset age (p=0.042), and more severe depressive symptoms (Hamilton Depression Rating Scale item 1-depressed mood (p=0.032) and item 2-guilt feelings (p=0.018)). At the logistic regression, higher severity of depressed mood (OR 1.568), higher BMI (OR 1.264), and younger age at onset (OR 0.935) were associated with long DUI. The present study confirmed a possible role of DUI as a construct underpinning higher clinical severity in affective spectrum disorders, possibly linked to worse illness course and unfavorable outcomes. Intervention strategies targeting physical comorbidities and depressive symptoms severity may decrease disease burden in subjects with a long DUI.

Abstract
OBJECTIVE To investigate the associations of symptoms of mania and depression with clinical outcomes in people with unipolar depression. DESIGN A natural language processing electronic health record study. We used network analysis to determine symptom network structure and multivariable Cox regression to investigate associations with clinical outcomes. SETTING The South London and Maudsley Clinical Record Interactive Search database. PARTICIPANTS All patients presenting with unipolar depression between 1 April 2006 and 31 March 2018. EXPOSURE (1) Symptoms of mania: Elation; Grandiosity; Flight of ideas; Irritability; Pressured speech. (2) Symptoms of depression: Disturbed mood; Anhedonia; Guilt; Hopelessness; Helplessness; Worthlessness; Tearfulness; Low energy; Reduced appetite; Weight loss. (3) Symptoms of mania or depression (overlapping symptoms): Poor concentration; Insomnia; Disturbed sleep; Agitation; Mood instability. MAIN OUTCOMES (1) Bipolar or psychotic disorder diagnosis. (2) Psychiatric hospital admission. RESULTS Out of 19 707 patients, at least 1 depression, overlapping or mania symptom was present in 18 998 (96.4%), 15 954 (81.0%) and 4671 (23.7%) patients, respectively. 2772 (14.1%) patients subsequently developed bipolar or psychotic disorder during the follow-up period. The presence of at least one mania (HR 2.00, 95% CI 1.85 to 2.16), overlapping symptom (HR 1.71, 95% CI 1.52 to 1.92) or symptom of depression (HR 1.31, 95% CI 1.07 to 1.61) were associated with significantly increased risk of onset of a bipolar or psychotic disorder. Mania (HR 1.95, 95% CI 1.77 to 2.15) and overlapping symptoms (HR 1.76, 95% CI 1.52 to 2.04) were associated with greater risk for psychiatric hospital admission than symptoms of depression (HR 1.41, 95% CI 1.06 to 1.88). CONCLUSIONS The presence of mania or overlapping symptoms in people with unipolar depression is associated with worse clinical outcomes. Symptom-based approaches to defining clinical phenotype may facilitate a more personalised treatment approach and better predict subsequent clinical outcomes than psychiatric diagnosis alone.

A piece of the puzzle: Does bipolarity partly explain the high prevalence of treatment resistance in depression? Psychiatry Res 2022; 307:114275. [PMID: 34847512 DOI: 10.1016/j.psychres.2021.114275] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 11/01/2021] [Accepted: 11/06/2021] [Indexed: 12/28/2022]
Abstract
In this cross-sectional study we examined whether the prevalence of treatment resistant depression (TRD) can be partly attributed to level of bipolarity. We included data of 201 patients with either episodic depression or TRD, who received treatment for their depression at either an outpatient or 2nd opinion/daytime setting, within a specialised mental healthcare department in the Netherlands. Whether level of TRD, assessed by the 'Dutch Measure for quantification of Treatment Resistance in Depression', can be partly explained by level of bipolarity, assessed by 'the Bipolarity Index', was examined using linear regression. We found no direct association between level of TRD and level of bipolarity, nor did comorbid anxiety disorders obscure an existing association. In this study we found no evidence for overlooked bipolarity contributing to the high prevalence of TRD. If replicated, we could state that additional screening on bipolarity with an instrument such as the 'Bipolarity Index' in the specialised mental health care is unnecessary.

Abstract
This study was conducted to examine whether there are quantitative or qualitative differences in the connectome between psychiatric patients and healthy controls and to delineate the connectome features of major depressive disorder (MDD), schizophrenia (SCZ) and bipolar disorder (BD), as well as the severity of these disorders. Toward this end, we performed an effective connectivity analysis of resting state functional MRI data in these three patient groups and healthy controls. We used spectral Dynamic Causal Modeling (spDCM), and the derived connectome features were further subjected to machine learning. The results outlined a model of five connections, which discriminated patients from controls, comprising major nodes of the limbic system (amygdala (AMY), hippocampus (HPC) and anterior cingulate cortex (ACC)), the salience network (anterior insula (AI), and the frontoparietal and dorsal attention network (middle frontal gyrus (MFG), corresponding to the dorsolateral prefrontal cortex, and frontal eye field (FEF)). Notably, the alterations in the self-inhibitory connection of the anterior insula emerged as a feature of both mood disorders and SCZ. Moreover, four out of the five connectome features that discriminate mental illness from controls are features of mood disorders (both MDD and BD), namely the MFG→FEF, HPC→FEF, AI→AMY, and MFG→AMY connections, whereas one connection is a feature of SCZ, namely the AMY→SPL connectivity. A large part of the variance in the severity of depression (31.6%) and SCZ (40.6%) was explained by connectivity features. In conclusion, dysfunctions in the self-regulation of the salience network may underpin major mental disorders, while other key connectome features shape differences between mood disorders and SCZ, and can be used as potential imaging biomarkers.

Abstract
Background and Objectives: Affective disorders, namely bipolar (BDs) and depressive disorders (DDs) are characterized by high prevalence and functional impairment. From a dimensional point of view, BDs and DDs can be considered as psychopathological entities lying on a continuum. A delay in treatment initiation might increase the burden associated with affective disorders. The aim of this study is to analyze the correlates of a long duration of untreated illness (DUI) in these conditions. Materials and Methods: Subjects with BDs and DDs, both in- and outpatients, were recruited. Long DUI was defined according to previous research criteria as >2 years for BDs or >1 year for DDs. Socio-demographic, clinical and psychopathological characteristics of the recruited subjects were collected. Bivariate analyses were performed to compare subjects with a long and short DUI (p < 0.05). Results: In our sample (n = 61), 34.4% of subjects presented a long DUI. A long DUI was significantly associated with longer overall illness duration (p = 0.022) and a higher rate of psychiatric (p = 0.048) and physical comorbidities (p = 0.023). As for psychopathological features, depressive symptoms were more severe in the long DUI subgroup, as demonstrated by a higher score at the Clinical Global Impression-severity of depression (p = 0.012) item and at the anxiety/depression factor of the Positive and Negative Syndrome Scale (p = 0.041). Furthermore, subjects with a long DUI displayed more severe disruption of circadian rhythms, as evaluated by the Biological Rhythms Interview for Assessment in Neuropsychiatry total (p = 0.044) and social domain (p = 0.005) scores and by the Hamilton Depression Rating Scale diurnal variation items (18a: p = 0.029, 18b: p = 0.047). Conclusions: A long DUI may underpin higher clinical severity, as well as worse illness course and unfavorable prognosis in affective disorders. Intervention strategies targeting comorbidities, depressive symptoms and circadian rhythms may decrease disease burden in subjects with a long DUI.

Abstract
According to DSM-IV, the criterion (A) for diagnosing hypomanic/manic episodes is mood change (i.e., elevated, expansive or irritable mood). Criterion (A) was redefined in DSM-5 in 2013, adding increased energy/activity in addition to mood change. This paper examines a potential change of prevalence data for bipolar I or II when adding increased energy/activity to the criterion (A) for the diagnosis of hypomania/mania. Own research suggests that the prevalence of manic/hypomanic episodes drops by at least one third when using DSM-5 criteria. Whether this has positive or negative impact on clinical practice and research still needs further evaluation.

Abstract
BACKGROUND Prevalence estimates of Bipolar Spectrum Disorders (BSD) remain scant in Southeast Asia. This study aims to investigate the prevalence of BSD, its correlates with sociodemographic factors, and the associations between the BSD subgroups and clinical severity, impairment, and disability in Singapore. METHODS This study utilizes data gathered from the second Singapore Mental Health Study (SMHS)- a nationwide cross-sectional survey conducted between 2016 and 2018 (response rate: 69.5%). Respondents were randomly selected and administered, in a single visit, interviewer-led surveys of the World Health Organization Composite International Diagnostic Interview version 3.0 (CIDI 3.0) in their preferred language (i.e. Chinese, Malay, Tamil, or English). A total of 6126 residents completed the study. RESULTS The lifetime weighted prevalence of BSD, Bipolar I, II, and subthreshold bipolar disorder was 3.1%, 1.5%, 0.03%, and 1.6% respectively. A higher prevalence of Bipolar Disorders (BPD) was significantly associated with younger age, being divorced or separated, and being unemployed. Lifetime comorbidity of BSD with at least one other psychiatric or physical condition was 45% and 51% respectively. BSD was most comorbid with Obsessive Compulsive Disorder (psychiatric condition) and Chronic pain (physical condition). LIMITATIONS This study relies on self-report data which may be subject to unintended response biases leading to the under or over-reporting of results. DISCUSSION In addition to the high prevalence of BPD, there is also a concerning shift and increase in the proportion of those who experience severe symptoms of mania/hypomania and depression. Subthreshold bipolar disorder is found to be clinically significant and cross-culturally valid in a multi-cultural setting.

Abstract
Major Depressive Episode (MDE) is a transdiagnostic nosographic construct straddling Major Depressive (MDD) and Bipolar Disorder (BD). Prognostic and treatment implications warrant a differentiation between these two disorders. Network analysis is a novel approach that outlines symptoms interactions in psychopathological networks. We investigated the interplay among depressive and mixed symptoms in acutely depressed MDD/BD patients, using a data-driven approach. We analyzed 7 DSM-IV-TR criteria for MDE and 14 researched-based criteria for mixed features (RBDC) in 2758 acutely depressed MDD/BD patients from the BRIDGE-II-Mix study. The global network was described in terms of symptom thresholds and symptom centrality. Symptom endorsement rates were compared across diagnostic subgroups. Subsequently, MDD/BD differences in symptom-network structure were examined using permutation-based network comparison test. Mixed symptoms were the most central and highly interconnected nodes in the network, particularly agitation followed by irritability. Despite mixed symptoms, appetite gain and hypersomnia were significantly more endorsed in BD patients, associations between symptoms were highly correlated across MDD/BD (Spearman's r = 0.96, p<0.001). Network comparison tests showed no significant differences among MDD/BD in network strength, structure, or specific edges, with strong edges correlations (0.66-0.78). Upstream differences in MDD/BD may produce similar symptoms networks downstream during acute depression. Yet, mixed symptoms, appetite gain and hypersomnia are associated to BD rather than MDD. Symptoms during mixed-MDE might aggregate according to 2 different clusters, suggesting a possible stratification within mixed states. Future symptom-based studies should implement clinical, longitudinal, and biological factors, in order to establish tailored therapeutic strategies for acute depression.

Abstract
AbstractObjectiveTo review the diagnostic validity and utility of mixed depression, i.e. co-occurrence of depression and manic/hypomanic symptoms.MethodsPubMed search of all English-language papers published between January 1966 and December 2006 using and cross-listing key words: bipolar disorder, mixed states, criteria, utility, validation, gender, temperament, depression-mixed states, mixed depression, depressive mixed state/s, dysphoric hypomania, mixed hypomania, mixed/dysphoric mania, agitated depression, anxiety disorders, neuroimaging, pathophysiology, and genetics. A manual review of paper reference lists was also conducted.ResultsBy classic diagnostic validators, the diagnostic validity of categorically-defined mixed depression (i.e. at least 2–3 manic/hypomanic symptoms) is mainly supported by family history (the current strongest diagnostic validator). Its diagnostic utility is supported by treatment response (negative effects of antidepressants). A dimensionally-defined mixed depression is instead supported by a non-bi-modal distribution of its intradepression manic/hypomanic symptoms.DiscussionCategorically-defined mixed depression may have some diagnostic validity (family history is the current strongest validator). Its diagnostic utility seems supported by treatment response.

Abstract
The study investigated the influence of religion and locus of control on perception of mental illness. Specifically, the study explored the relationship between religiosity and perception of mental illness, differences in perception by internals and externals, the effect of knowledge on perception of mental illness and the interactive effect of religiosity and locus of control on perception of mental illness. Data were collected from 200 participants in the Volta Region of Ghana. Three hypotheses were tested in the study using a battery of tests. It was observed that people with internal locus of control perceive mental patients positively than those with external locus of control. A significant interactive effect between religiosity and locus of control on perception of mental illness was observed. Religiosity significantly relates to perception of mental illness. The results and implications are discussed for further studies.

Is recurrence in major depressive disorder related to bipolarity and mixed features? Results from the BRIDGE-II-Mix study. J Affect Disord 2018; 229:164-170. [PMID: 29310066 DOI: 10.1016/j.jad.2017.12.062] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2017] [Revised: 11/28/2017] [Accepted: 12/31/2017] [Indexed: 11/23/2022]
Abstract
BACKGROUND Current classifications separate Bipolar (BD) from Major Depressive Disorder (MDD) based on polarity rather than recurrence. We aimed to determine bipolar/mixed feature frequency in a large MDD multinational sample with (High-Rec) and without (Low-Rec) >3 recurrences, comparing the two subsamples. METHODS We measured frequency of bipolarity/hypomanic features during current depressive episodes (MDEs) in 2347 MDD patients from the BRIDGE-II-mix database, comparing High-Rec with Low-Rec. We used Bonferroni-corrected Student's t-test for continuous, and chi-squared test, for categorical variables. Logistic regression estimated the size of the association between clinical characteristics and High-Rec MDD. RESULTS Compared to Low-Rec (n = 1084, 46.2%), High-Rec patients (n = 1263, 53.8%) were older, with earlier depressive onset, had more family history of BD, more atypical features, suicide attempts, hospitalisations, and treatment resistance and (hypo)manic switches when treated with antidepressants, higher comorbidity with borderline personality disorder, and more hypomanic symptoms during current MDE, resulting in higher rates of mixed depression according to both DSM-5 and research-based diagnostic (RBDC) criteria. Logistic regression showed age at first symptoms < 30 years, current MDE duration ≤ 1 month, hypomania/mania among first-degree relatives, past suicide attempts, treatment-resistance, antidepressant-induced swings, and atypical, mixed, or psychotic features during MDE to associate with High-Rec. LIMITATIONS Number of MDEs for defining recurrence was arbitrary; cross-sectionality did not allow assessment of conversion from MDD to BD. CONCLUSIONS High-Rec MDD differed from Low-Rec group for several clinical/epidemiological variables, including bipolar/mixed features. Bipolarity specifier and RBDC were more sensitive than DSM-5 criteria in detecting bipolar and mixed features in MDD.

Abstract
Major depressive disorder (MDD) is not a single disease, but a number of various ailments that form one entity. Psychomotor retardation, anhedonia, sleep disorders, an increased suicide risk, and anxiety are the main symptoms that often define the clinical diagnosis of depression. Interleukin-6 (IL-6), as one of the proinflammatory cytokines, seems to be overexpressed during certain mental disorders, including MDD. Overexpression of IL-6 in depression is thought to be a factor associated with bad prognosis and worse disease course. IL-6 may directly affect brain functioning and production of neurotransmitters; moreover, its concentration is correlated with certain clinical symptoms within the wide range of depressive symptomatology. Furthermore, there is a strong correlation between IL-6 synthesis and psychosomatic functioning of the patient. This article discusses potential sources and significance of IL-6 in the pathogenesis of depression.

Abstract
This study examined whether acceptance and commitment therapy (ACT) enhances treatment as usual (TAU) in improving treatment outcomes in patients with alcohol use disorder (AUD) and comorbid affective disorder. Fifty-two participants were included in the study, of whom 26 were patients with AUD and either depression or bipolar disorder treated with ACT group therapy in parallel with TAU (inpatient integrated treatment) and 26 were matched controls who had received TAU alone. Drinking and craving outcomes were total alcohol abstinence, cumulative abstinence duration (CAD) and Obsessive Compulsive Drinking Scale (OCDS) scores at 3 and 6 months postintervention. Affective and anxiety outcomes were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and Young Mania Rating Scale (YMRS) scores at these follow-ups. Baseline demographic and clinical characteristics were similar in both groups. Retention rates were high: 100% of the ACT group were followed up at 3 and 6 months; 92.3% and 84.6% of the TAU alone group were followed up at 3 and 6 months, respectively. Patients in the ACT group reported significantly higher CAD at 3 and 6 months, significantly lower BDI and BAI scores at 3 and 6 months, and significantly lower OCDS scores at 3 months, than those who received only TAU. No other significant differences in treatment outcomes were found between the groups. ACT provides added benefit to TAU in improving drinking, craving, depression and anxiety outcomes in patients with AUD and comorbid affective disorder. Most treatment improvements were sustained over a 6-month follow-up period.

Abstract
This study aims to characterize and compare functional brain single photon emission tomography (SPECT) perfusion and connectivity in treatment-resistant depression (TRD) according to distinct demographic or clinical profiles (male vs. female; old vs. young; unipolar vs. bipolar) and to study their relationship to the severity and the duration of episode/illness. We retrospectively included 127 consecutive patients who met DSM-IV criteria for a nonpsychotic major TRD episode. All patients were studied using (99m)Tc-ethyl cysteinate dimer SPECT. Whole-brain, voxel-based, between-groups analyses were performed according to demographic and clinical data and in comparison to 37 healthy subjects. Voxel-wise interregional correlation was also performed to compare functional SPECT connectivity. Finally, relationships were searched for regarding severity and duration of episode/illness. The whole group of patients exhibited significant hypoperfusion within bilateral fronto-temporal, insular, and anterior cingulate cortices, as well as within the left caudate. Functional connectivity between left frontal and left cerebellar regions was higher in patients than in healthy subjects. Gender, age, and type of mood disorder did not influence these SPECT patterns. A significant relationship was found between brain SPECT perfusion and either duration or global severity of illness in particular frontal areas. Our data support the hypothesis of a shared SPECT pattern, whatever the profile of TRD, involving fronto-temporal regions and the cerebellum.

Abstract
The DSM-5 definition of mixed features "specifier" of manic, hypomanic and major depressive episodes captures sub-syndromal non-overlapping symptoms of the opposite pole, experienced in bipolar (I, II, and not otherwise specified) and major depressive disorders. This combinatory model seems to be more appropriate for less severe forms of mixed state, in which mood symptoms are prominent and clearly identifiable. Sub-syndromal depressive symptoms have been frequently reported to co-occur during mania. Similarly, manic or hypomanic symptoms during depression resulted common, dimensionally distributed, and recurrent. The presence of mixed features has been associated with a worse clinical course and high rates of comorbidities including anxiety, personality, alcohol and substance use disorders and head trauma or other neurological problems. Finally, mixed states represent a major therapeutic challenge, especially when you consider that these forms tend to have a less favorable response to drug treatments and require a more complex approach than non-mixed forms.

Abstract
The 24-item Brief Psychiatric Rating Scale (BPRS, version 4.0) enables the rater to measure psychopathology severity. Still, little is known about the BPRS's reliability and validity outside of the psychosis spectrum. The aim of this study was to examine the factorial structure and sensitivity to change of the BPRS in patients with unipolar depression. Two hundred and forty outpatients with unipolar depression were administered the 24-item BPRS. Assessments were conducted at intake and at post-treatment in a Crisis Intervention Centre. An exploratory factor analysis of the 24-item BPRS produced a six-factor solution labelled "Mood disturbance", "Reality distortion", "Activation", "Apathy", "Disorganization", and "Somatization". The reduction of the total BPRS score and dimensional scores, except for "Activation", indicates that the 24-item BPRS is sensitive to change as shown in patients that appeared to have benefited from crisis treatment. The findings suggest that the 24-item BPRS could be a useful instrument to measure symptom severity and change in symptom status in outpatients presenting with unipolar depression.

Abstract
Studies of the 1970s and 1980s showed lithium monotherapy to be an effective treatment of acute unipolar major depressive disorder (MDD) and hence as a potential alternative to monoaminergic antidepressants.The objective was to conduct the first comparison of a lithium monotherapy with a modern antidepressant in the acute treatment of MDD. Results were compared with citalopram's efficacy as shown in a different but methodologically identical study (including same researchers, same time, and same place).Thirty patients with an acute MDD (Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM IV] I) were treated with lithium monotherapy (study 1) or with citalopram monotherapy (study 2, N = 32) for 4 weeks.Response rates (decrease in Hamilton Depression Rating Scale score >50%) were 50% for lithium and 72% for citalopram (P = 0.12). Citalopram-treated subjects showed a greater decrease in Hamilton Depression Rating Scale scores (significant at 2 weeks). In the lithium study, only patients with a recurrent episode (DSM-IV: 296.3) responded (15/22), as opposed to none of 8 patients with a first/single episode (DSM-IV: 296.2) (P = 0.002). Patients with a single episode responded significantly more often to citalopram than to lithium (P = 0.007). Both drugs were well tolerated. Only one patient (citalopram) terminated the study prematurely owing to adverse effects.Our results do not support the use of lithium as an alternative to SSRI in the treatment of acute MDD. The finding of a better response to lithium in patients with a recurrent depression has not been reported before and warrants replication. The comparison is limited by the lack of a randomized double-blind design.

Abstract
BACKGROUND TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire) is a self-rated instrument that measures five affective temperaments: depressive, cyclothymic, hyperthymic, irritable, and anxious. The aim of our study was to examine the psychometric characteristics of the Slovenian TEMPS-A and to ascertain if temperament profile is related to the professions chosen by Slovenian students. METHODS 892 Slovenian university students in six different professional fields (economics, geography, engineering, law, sports pedagogy and nursing) were included in our study. RESULTS Cronbach's reliability coefficients denoted acceptable internal consistency of the subscales. Principal component analysis revealed relatively good internal structure of the instrument. Nursing and geography students scored the highest on depressive temperament. Sports pedagogues as well as engineers demonstrated the most firm personality structure with distinctive hyperthymic temperament. Law students revealed the most irritable temperament, while nursing and law students scored the highest on anxious temperament. LIMITATIONS Sample of Slovenian students is not representative for general population. The structure of the sample was crucial as well, as it comprised mainly of younger students who just started their study. CONCLUSIONS The Slovenian version of the TEMPS-A proved to have relatively good internal consistency and internal structure. The questionnaire verified as a reliable and valid instrument and generally in line with previous studies. This study strengthens the perspective that professional areas could be associated with distinct affective temperament profile that could influence career decisions. The findings in students of economics, geography, and sport pedagogy are new as they have not been previously investigated by TEMPS researchers. The results open new possibilities for future research.

Abstract
OBJECTIVES Current clinical and epidemiological research provides support for a continuum of bipolar psychopathology: a bipolar spectrum that ranges from subclinical manifestations to full-blown bipolar disorders. Examining subthreshold bipolar symptoms may identify individuals at risk for clinical disorders, promote early interventions and monitoring, and increase the likelihood of appropriate treatment. The present studies examined the construct validity of bipolar spectrum psychopathology using the Hypomanic Personality Scale. METHODS Study 1 used interview and questionnaire measures of bipolar spectrum psychopathology in a sample of 145 nonclinically ascertained young adults. Study 2 assessed the expression of the bipolar spectrum in daily life using experience sampling methodology in the same sample. RESULTS In study 1, Hypomanic Personality Scale scores were positively associated with clinical bipolar disorders, bipolar spectrum disorders, the presence of hypomania or hyperthymia, depressive symptoms, poor psychosocial functioning, cyclothymia, irritability, and symptoms of borderline personality disorder. In study 2, bipolar spectrum psychopathology was associated with negative affect, thought disturbance, risky behavior, and measures of grandiosity. These findings remained independent of clinical bipolar disorders. CONCLUSIONS In the present studies, bipolar-like disruptions in cognition, affect, and behavior were not limited to clinical diagnoses or mood episodes, providing further validation of the bipolar spectrum construct. The bipolar spectrum model appears to provide a conceptually richer basis for understanding and ultimately treating bipolar psychopathology than current diagnostic formulations.

Abstract
OBJECTIVE Bipolar affective disorder and borderline personality disorder have long been considered to have significant similarities and comorbidity. This review endeavours to clarify the similarities and differences between these disorders, with an effort to determine whether they reflect different forms of the same illness or separate illness clusters. METHOD The published literature relating to bipolar affective disorders, borderline personality disorders, and related areas of knowledge was reviewed using searches of several electronic databases (AMED, CINHAL, Embase, Ovid, ProQuest, MEDLINE, Web of Science, ScienceDirect) and published texts. These findings were combined with the personal clinical experience of the author, and information gathered from colleagues, to create a review of this topic. RESULTS Bipolar affective disorders and borderline personality disorders differ with respect to sense of self, disruption of relationships, family history of bipolar disorders, the benefits of medications, the extent of cognitive deficits, the form of affective dysregulation and mood cycling, the incidence of suicide and suicide attempts, the form of psychotic episodes, the incidence of early sexual abuse but not early trauma in general, the loss of brain substance, alterations in cortical activity, glucocorticoid receptor sensitivity, and mitochondrial dysfunction. They are similar with respect to non-specific features of affective dysregulation, the incidence of atypical depressive features, the incidence of self-mutilation, the incidence of transporter polymorphisms, possible genetic linkages, overall reduction in limbic modulation, reduction in the size of hippocampi and amygdala, and the incidence of sleep disruption. CONCLUSIONS This review concludes that bipolar affective disorders and borderline personality disorder are separate disorders, but have significant elements in common.

Abstract
BACKGROUND It has been held that if bipolar disorder is categorically distinct, it should differentiate from unipolar depressive disorders by showing bimodality or a 'zone of rarity' in bipolar symptom scores. Two previous studies have failed to demonstrate bimodality. We undertook a third study. METHODS A total of 1106 patients attending the Black Dog Institute Depression Clinic completed the Mood Disorders Questionnaire (MDQ), in addition to undergoing clinical assessment by an Institute psychiatrist. RESULTS The distributions of scores for the total number of hypomanic symptoms endorsed by unipolar and bipolar patients were both skewed, with the bipolar group endorsing a high number of hypomanic symptoms and the unipolar group endorsing few symptoms--and so giving the impression of an 'even' distribution generated by two quite distinctly differing sub-groups. However, formal statistical analyses involving mixed modelling provided no clear evidence that a bimodal distribution provided a better fit to the data than a unimodal one. CONCLUSIONS Failure to statistically demonstrate a 'point of rarity' did not marry with visual inspection of the plotted data--which clearly suggested two groups putatively capturing those with bipolar and unipolar disorders respectively. The paper considers some limitations to the emphasis on 'bimodality' in differentiating potentially differing conditions.

More severe impairment of manual dexterity in bipolar disorder compared to unipolar major depression. J Affect Disord 2012; 136:1047-52.

Abstract
BACKGROUND Mood disorders are associated with various neurocognitive deficits. However, few studies have reported the impairment of motor dexterity in unipolar depression and bipolar disorder. In the present study, manual dexterity was compared between unipolar major depression, bipolar disorder, and healthy controls. METHODS Manual dexterity was assessed by the Purdue pegboard test in 98 patients with unipolar major depression, 48 euthymic or depressed patients with bipolar disorder, and 158 healthy controls, matched for age and gender. RESULTS Compared to healthy controls, sum of the scores of right, left, and both hands subtests (R+L+B) was significantly lower in both patients with unipolar depression and bipolar disorder (P=0.0034 and P<0.0001, respectively). Furthermore, R+L+B was significantly lower in bipolar disorder compared to unipolar depression (P=0.0016). Lithium dose and chlorpromazine equivalent dose of antipsychotics were significantly negatively correlated with some of the subtest scores. On the other hand, depression severity did not significantly correlate with any of the subtest scores. Difference in R+L+B between unipolar depression and bipolar disorder remained statistically significant even after controlling for gender, age, lithium dose, and chlorpromazine equivalent dose (P=0.0028). Limitations Bipolar patients during manic episode were not included in the study. CONCLUSIONS Gross movement dexterity was impaired in both patients with unipolar depression and bipolar disorder. The severity of impairment was significantly greater in patients with bipolar disorder. The functional difference between unipolar and bipolar patients may suggest different pathological conditions between the two depressive disorders.

Abstract
Current gold standard approaches to the treatment of depression include pharmacotherapeutic and psychotherapeutic interventions with social support. Due to current controversies concerning the efficacy of antidepressants in randomized controlled trials, the generalizability of study findings to wider clinical practice and the increasing importance of socioeconomic considerations, it seems timely to address the uncertainty of concerned patients and relatives, and their treating psychiatrists and general practitioners. We therefore discuss both the efficacy and clinical effectiveness of antidepressants in the treatment of depressive disorders. We explain and clarify useful measures for assessing clinically meaningful antidepressant treatment effects and the types of studies that are useful for addressing uncertainties. This includes considerations of methodological issues in randomized controlled studies, meta-analyses, and effectiveness studies. Furthermore, we summarize the differential efficacy and effectiveness of antidepressants with distinct pharmacodynamic properties, and differences between studies using antidepressants and/or psychotherapy. We also address the differential effectiveness of antidepressant drugs with differing modes of action and in varying subtypes of depressive disorder. After highlighting the clinical usefulness of treatment algorithms and the divergent biological, psychological, and clinical efforts to predict the effectiveness of antidepressant treatments, we conclude that the spectrum of different antidepressant treatments has broadened over the last few decades. The efficacy and clinical effectiveness of antidepressants is statistically significant, clinically relevant, and proven repeatedly. Further optimization of treatment can be helped by clearly structured treatment algorithms and the implementation of psychotherapeutic interventions. Modern individualized antidepressant treatment is in most cases a well-tolerated and efficacious approach to minimize the negative impact of otherwise potentially devastating and life-threatening outcomes in depressive disorders.

Abstract
OBJECTIVE Current criteria for mixed bipolar episode do not allow an adequate understanding of a vast majority of bipolar patients with mixed (hypo) manic-depressive features, keeping the qualification of "mixed episodes" for bipolar type I only. This study was aimed to test the existence of a bipolar-mixed continuum by comparing the characteristics of three groups classified according to patterns of past and current manic or mixed episodes. METHOD 134 bipolar I inpatients were divided according to their pattern of excitatory "mixed-like" episodes in three groups: 1) lifetime history of purely manic episodes without mixed features (PMA); 2) lifetime history of both manic and mixed episodes (MIX) and 3) lifetime history exclusively of mixed, but not manic, episodes (PMIX). Differences in clinical and demographic characteristics were analyzed by using chi-square head-to-head for categorical data, one-way ANOVA for continuous variables and Tukey's post-hoc comparison. Logistic regression was used to control for data validity. RESULTS PMIX had higher rates of depressive predominant polarity and less lifetime history of psychotic symptoms, and had received more antidepressants both lifetime and during 6 months prior to index episode. PMIX had more suicide attempts and Axis I comorbidity than PMA. DISCUSSION PMIX is likely to have a higher risk for suicide and higher rates of comorbidities; current DSM-IV-TR criteria are not fit for correctly classifying these patients and this may affect treatment appropriateness. The concept of "mixicity" should be extended beyond bipolar I disorder to other bipolar disorder subtypes.

Abstract
OBJECTIVES The taxonic versus dimensional status of mood symptoms has been the subject of debate among mental health professionals. Conventional diagnostic models suggest that mood disorders are categorical; however, the inability of categorical models to adequately account for subthreshold unipolar and bipolar presentations and the heterotypic continuity of symptoms in unipolar and bipolar cases has resulted in growing support for dimensional views. The current study sought to evaluate the relative viabilities of categorical and dimensional models of mood symptoms within a taxometric framework. METHODS We examined the latent structure of mood symptoms in an epidemiological sample drawn from the Collaborative Psychiatric Epidemiological Surveys. Using three taxometric procedures (MAMBAC, MAXEIG, and L-Mode), we analyzed indicators of mania and depression created from the mood symptoms section of the survey. RESULTS The taxometric analyses supported a taxonic rather than dimensional structure for mania and depression. Membership in the mania and depressive taxa was associated with meeting criteria for DSM-IV lifetime manic episode and major depressive disorder, respectively. We identified a subset of 700 individuals falling into both taxa; membership in this subset was associated with lifetime bipolar disorder status. Group membership predicted designated external variables including help-seeking, family history, and duration of impairment. Within taxon and/or complement groups, severity scores still appeared to predict external variables. CONCLUSION Our findings suggest that although taxonic, mood disorders possess meaningful dimensional variation.

Abstract
BACKGROUND The dichotomous distinction between unipolar and bipolar disorders may be challenged by heterogeneity within diagnoses and overlap between different diagnoses. A broad mood disorder category in which patients differ as a result of variation along separate manic and depressive mood dimensions can be proposed. To test this, it is hypothesized that heterogeneity in clinical and other features of subjects selected for unipolar depression can be partly explained by coexisting manic symptoms. METHODS A cohort selected for unipolar depressive disorder was followed up for two years at which time co-occurring manic symptoms were assessed, yielding four groups with increasing manic symptomatology: i) pure unipolar depressive disorder (n=1598), ii) unipolar depressive disorder with subthreshold manic symptomatology (n=64), iii) bipolar II disorder (n=39), and iv) bipolar I disorder (n=86). Multivariate logistic regression and analyses of covariance controlled for depression severity were used to investigate whether patients with increasing manic symptomatology could be differentiated from patients with pure depressive disorder. RESULTS Male gender, a lower age at first episode, a history of suicide attempts and increased aggressive cognitions were independently associated with an increase in manic symptoms. The additional presence of (hypo)mania was associated with greater depression severity and more disability than pure depressive disorder. LIMITATIONS The groups with manic symptomatology (subthreshold, hypomania and mania) were considerably smaller compared to the pure depression group. CONCLUSIONS The heterogeneity in depressive illness can be partly explained by the coexisting variation along the manic symptom dimension. Co-occurring manic symptoms should be taken into account in depression and a symptom dimensional approach of mood disorders may provide phenotypes that are more informative than current mood disorder categories.

Abstract
BACKGROUND The study aimed at determining the temperamental underpinnings of bipolar spectrum disorders (BSD) in the first-degree relatives (FDR) of patients with bipolar I disorder in comparison with control subjects. SAMPLING AND METHODS The sample consisted of 198 subjects: 33 bipolar I probands and their 33 FDR in the experimental group, 33 schizophrenia probands and their 33 FDR in the patient control group, and 33 normal healthy controls and their 33 FDR. The affective temperament and the BSD were assessed using the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire and the criteria of Ghaemi et al. [Can J Psychiatry 2002;47:125-134], respectively. RESULTS Among the FDR of bipolar I probands, 27.3% satisfied the diagnosis of BSD, which was significantly higher than in the other groups (relative risk = 6, 95% CI = 1.74-20.69). Bipolar probands were significantly more hyperthymic as compared to controls (relative risk = 2, 95% CI = 1.34-2.98), and both the FDR of the bipolar and the FDR of the patient control groups were significantly more hyperthymic as compared to the FDR of the normal controls (relative risk = 1.52, 95% CI = 0.93-2.51). FDR (of bipolar patients) with BSD had a significantly higher total irritable temperament score as compared to FDR (of bipolar patients) without BSD (mean difference = 2.07, 95% CI = 0.64-3.50). CONCLUSIONS Our findings support the fact that the whole spectrum of bipolarity is transmitted in susceptible families. The graded distribution of hyperthymia suggests it to be a milder expression of bipolarity in the FDR of bipolar patients. The irritable temperament appears to be a specific vulnerability marker for the development of BSD.

Abstract
BACKGROUND Many people with bipolar disorder (BD) in the community are misdiagnosed with major depressive disorder (MDD). A probabilistic model has been proposed to assist in the identification of BD among patients with depressive symptoms, however there are limited population-based data on the key distinguishers of BD from MDD. The objective of this study was to identify distinguishers of BD from MDD in a population-based sample. METHODS Population-based data were extracted from the Canadian Community Health Survey: Mental Health and Well-Being. Sociodemographic variables, clinical variables, and depressive symptomatology were compared between subjects with BD (N=467) and MDD (N=4145). Logistic regression analysis was used to identify significant correlates of BD, and areas under the receiver operating characteristic curves (AUCs) were determined for each model. RESULTS BD and MDD subjects differed across a number of characteristics. Clinical variables significantly associated with BD included greater number of lifetime depressive episodes, earlier age of first depressive episode, lifetime anxiety disorder, problematic substance use, and lifetime suicide attempt. Symptoms significantly more common during a major depressive episode among BD subjects included agitation, suicidal ideation, anxious symptoms, and irritability. AUCs for these models ranged from 0.72 to 0.81. LIMITATIONS Data were not available for all potential distinguishers; subgroups of BD could not be determined; cross-sectional data. CONCLUSIONS These population-based results reinforce the effort to establish a generalizable probabilistic model that incorporates clinical and symptom variables in order to assist clinicians in the diagnostic assessment of BD.

Abstract
OBJECTIVE To assess rates of conversion to bipolar spectrum disorder (BPSD) and risk factors associated with conversion in children with depressive spectrum disorders (DSD) and transient manic symptoms (TMS) over 18 months. TMS are manic-like symptoms of insufficient duration or number to warrant a diagnosis of BPSD. METHODS Participants were 165 children (mean = 9.9 years, SD = 1.3) with mood disorders from the Multi-Family Psychoeducational Psychotherapy (MF-PEP) treatment study: 37 with DSD+TMS, 13 with DSD, and 115 with BPSD. All were assessed with standardized instruments on four occasions over 18 months, with half receiving MF-PEP after their baseline assessment and half receiving MF-PEP after a one-year wait-list condition. RESULTS At baseline, the Children's Global Assessment Scale scores did not differ significantly between the DSD+TMS, DSD, and BPSD groups. Conversion rates to BPSD were significantly higher for the DSD+TMS group (48.0%) compared to the DSD group (12.5%). Conversion was significantly more frequent for participants in the one-year wait-list control group (60%) compared to the immediate treatment group (16%). Clinical presentation, family environment, and family history did not differ significantly between the small subset of DSD+TMS participants who did convert to BPSD at follow-up and those who did not convert. Baseline functional impairment was greater for the converted group than the non-converted group. CONCLUSIONS Transient manic symptoms are a risk factor for eventual conversion to BPSD; psychoeducational psychotherapy may be protective. As this exploratory study had a small sample size and did not correct for multiple comparisons, additional studies with larger sample sizes are needed.

Abstract
Life stress is a robust risk factor for later development of mood disorders, particularly for individuals at familial risk. Likewise, scoring high on the personality trait neuroticism is associated with an increased risk for mood disorders. Neuroticism partly reflects stress vulnerability and is positively correlated to frontolimbic serotonin 2A (5-HT(2A)) receptor binding. Here, we investigate whether neuroticism interacts with familial risk in relation to frontolimbic 5-HT(2A) receptor binding. Twenty-one healthy twins with a co-twin history of mood disorder and 16 healthy twins without a co-twin history of mood disorder were included. They answered self-report personality questionnaires and underwent [(18)F]altanserin positron emission tomography. We found a significant interaction between neuroticism and familial risk in predicting the frontolimbic 5-HT(2A) receptor binding (p=0.026) in an analysis adjusting for age and body mass index. Within the high-risk group only, neuroticism and frontolimbic 5-HT(2A) receptor binding was positively associated (p=0.0037). In conclusion, our data indicate that familial risk and neuroticism interact in their relation to frontolimbic 5-HT(2A) receptor binding. These findings point at a plausible neurobiological link between genetic and personality risk factors and vulnerability to developing mood disorders. It contributes to our understanding of why some people at high risk develop mood disorders while others do not. We speculate that an increased stress reactivity in individuals at high familial risk for mood disorders might enhance the effect of neuroticism in shaping the impact of potential environmental stress and thereby influence serotonergic neurotransmission.

Suicide attempt characteristics may orientate toward a bipolar disorder in attempters with recurrent depression. J Affect Disord 2010; 122:53-9.

Abstract
BACKGROUND Identification of patients with a bipolar disorder (BPD) among those presenting a major depressive episode is often difficult, resulting in common misdiagnosis and mistreatment. Our aim was to identify clinical variables unrelated to current depressive episode and relevant to suicidal behavior that may help to improve the detection of BPD in suicide attempters presenting with recurrent major depressive disorder. METHOD 211 patients suffering from recurrent major depressive disorder or BPD, hospitalized after a suicide attempt (SA), were interviewed by semi-structured interview and validated questionnaires about DSM-IV axis I disorders, SA characteristics and a wide range of personality traits relevant to suicidal vulnerability. Multivariate logistic regression analysis was performed to determine differences between RMDD and BPD attempters. RESULTS Logistic regression analysis showed that serious SA and family history of suicide are closely associated with a diagnosis of BPD [respectively OR=2.28, p=0.0195; OR=2.98, p=0.0081]. The presence of both characteristics increase the association with BDP [OR=4.78, p=0.005]. Conversely, when looking for the features associated with a serious SA, BPD was the only associated diagnosis [OR=2.03, p=0.004]. Lastly, affect intensity was higher in BPD samples [OR=2.08, p=0.041]. LIMITATIONS Retrospective nature of the study, lack of the separate analysis of bipolar subtypes. CONCLUSION Serious suicide attempt and a familial history of completed suicide in patients with major depression seem to be a clinical marker of bipolarity. Facing suicide attempters with recurrent depression, clinician should be awareness to these characteristics to detect BPD.

Abstract
The aim of this study was to analyze the relationship of residual mood and panic-agoraphobic spectrum phenomenology to functional impairment and quality of life in 226 adult outpatients who had remitted from a major depressive episode. Quality of life and functioning were assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire and the Work and Social Adjustment Scale. Residual symptoms were assessed using the Mood and Panic-Agoraphobic Spectrum Questionnaires. Linear and logistic regression models were used to analyze the relationship of mood and panic-agoraphobic spectrum factors with quality of life and functioning. Poor quality of life was associated with the Mood Spectrum Self-Report Questionnaire factors 'depressive mood' and 'psychotic features' and the Panic-Agoraphobic Spectrum Self-Report Questionnaire factors 'separation anxiety' and 'loss sensitivity'. Functional impairment was associated with the Mood Spectrum Self-Report Questionnaire factor 'psychomotor retardation' and the Panic-Agoraphobic Spectrum Self-Report Questionnaire factor 'fear of losing control'. These relationships were held after controlling for the severity of depression at the entry in the continuation treatment phase. In conclusion, the spectrum assessment is a useful tool for clinicians to identify areas of residual symptomatology that can be targeted with focused and effective long-term treatment strategies.

Abstract
OBJECTIVE To assess the rate of comorbidities and the functional impairment associated with the social anxiety disorder (SAD), with an emphasis on the so-called subthreshold clinical signs and symptoms. METHOD Psychiatric comorbidities and psychosocial functioning were evaluated in 355 volunteers (college students) who had been diagnosed as SAD (n = 141), Subthreshold SAD (n = 92) or Controls (n = 122). RESULTS The rate of comorbidities was 71.6% in the SAD group and 50% in subjects with Subthreshold SAD, both significantly greater than Controls (28.7%). Concerning psychosocial functioning, the SAD group had higher impairment than the other two groups in all domains evaluated, and subjects with Subthreshold SAD presented intermediate values. CONCLUSION The rates of psychiatric comorbidities and the impairment of psychosocial functioning increase progressively along the spectrum of social anxiety. The fact that Subthreshold SAD causes considerable disability and suffering in comparison with control subjects justifies a review of the validity of the diagnostic criteria.

Abstract
A model of staging in the field of bipolar disorder (BD) should offer a means for clinicians to predict response to treatment and more general outcome measures, such as the level of functioning and autonomy. The present staging model emphasizes the assessment of patients in the interepisodic period and includes: latent phase: individuals who present mood and anxiety symptoms and increased risk for developing threshold BD; Stage I--patients with BD who present well established periods of euthymia and absence of overt psychiatric morbidity between episodes; Stage II--patients who present rapid cycling or current axis I or II comorbidities; Stage III--patients who present a clinically relevant pattern of cognitive and functioning deterioration, as well as altered biomarkers; and Stage IV--patients who are unable to live autonomously and present altered brain scans and biomarkers. Such a model implies a longitudinal appraisal of clinical variables, as well as assessment of neurocognition and biomarkers in the interepisodic period. Staging facilitates understanding of the mechanisms underlying progression of the disorder, assists in treatment planning and prognosis and, finally, underscores the imperative for early intervention.

Although there is substantial variation in the results depending upon the methodological characteristics of the studies, the findings converge in demonstrating that approximately one fourth of youth experience a mental disorder during the past year, and about one third across their lifetimes. Anxiety disorders are the most frequent conditions in children, followed by behavior disorders, mood disorders, and substance use disorders. Fewer than half of youth with current mental disorders receive mental health specialty treatment. However, those with the most severe disorders tend to receive mental health services. Current issues that are now being identified in the field of child psychiatric epidemiology include: refinement of classification and assessment, inclusion of young children in epidemiologic surveys, integration of child and adult psychiatric epidemiology, and evaluation of both mental and physical disorders in children.

Abstract
BACKGROUND It is difficult to assess the effectiveness of treatments in lowering suicide incidence. METHODS To ascertain the impact of antidepressants (AD) on suicidal behavior, we compared the psychopharmacological treatment taken in the previous 3 months by cases who had made or not a suicide attempt (SA) just before their admission to a hospital. RESULTS In comparison with not SA cases, SA cases were more likely to have received AD and benzodiazepines (BZD) before hospitalization. On the contrary, they were less likely to have received antipsychotics, antiepileptic mood stabilizers, and lithium. Similar results were observed when the analysis was restricted to cases with a diagnosis of Major Depression, Bipolar Depression or Bipolar Mixed state, Schizoaffective Disorder, Depressive or Mixed type. Previous AD treatment seemed to be not related to the severity of psychopathology in general or to the severity of depressive and anxiety symptoms. CONCLUSIONS The results suggest that the use of AD in patients with mood disorders is not associated with a reduction of SA rate. Rather, it is not possible to exclude that AD or BZD can induce, worsen, or precipitate suicidal behavior in some patients, especially in those affected by mood disorders with Depressive or Mixed features. The results must be considered preliminary since this is an open, non-randomized, non-controlled study that was carried out at a single facility.

Abstract
BACKGROUND Western studies indicate a high prevalence of bipolar II disorder defined by a Research Diagnostic Criteria 2-day hypomania duration criterion (30 to 61%) amongst clinically depressive patients. The situation in Chinese patients with depression is unknown. METHODS 64 (52.5% response rate) patients first presenting to a Hong Kong public psychiatric outpatient clinic in 2005 with a diagnosis of major depression were recruited. The SCID and Family History Screen were administered. RESULTS DSM-IV bipolar II was found in 20.5% of depressive outpatients; 35.9% had bipolar II disorder defined by RDC 2-day duration criterion for hypomania. Family bipolarity, age of onset, and depressive recurrence distinguished bipolar II subjects from unipolar depressives irrespective of duration criteria chosen for hypomania. LIMITATIONS Sample size was limited. CONCLUSIONS Bipolar II disorder is common amongst Chinese depressive outpatients. The evaluation method and 2-day duration criterion for hypomania were supported by bipolar validators. Replication using larger samples is needed to arrive at a more representative prevalence estimate and to enable more refined nosological evaluation.

Abstract
BACKGROUND The observation that bipolar disorders frequently go unrecognized has prompted the development of screening instruments designed to improve the identification of bipolarity in clinical and non-clinical samples. Starting from a lifetime approach, researchers of the Spectrum Project developed the Mood Spectrum Self-Report (MOODS-SR) that assesses threshold-level manifestations of unipolar and bipolar mood psychopathology, but also atypical symptoms, behavioral traits and temperamental features. The aim of the present study is to examine the structure of mania/hypomania using 68 items of the MOODS-SR that explore cognitive, mood and energy/activity features associated with mania/hypomania. METHODS A data pool of 617 patients with bipolar disorders, recruited at Pittsburgh and Pisa, Italy was used for this purpose. Classical exploratory factor analysis, based on a tetrachoric matrix, was carried out on the 68 items, followed by an Item Response Theory (IRT)-based factor analytic approach. RESULTS Nine factors were initially identified, that include Psychomotor Activation, Creativity, Mixed Instability, Sociability/Extraversion, Spirituality/Mysticism/Psychoticism, Mixed Irritability, Inflated Self-esteem, Euphoria, Wastefulness/Recklessness, and account overall for 56.4% of the variance of items. In a subsequent IRT-based bi-factor analysis, only five of them (Psychomotor Activation, Mixed Instability, Spirituality/Mysticism/Psychoticism, Mixed Irritability, Euphoria) were retained. CONCLUSIONS Our data confirm the central role of Psychomotor Activation in mania/hypomania and support the definitions of pure manic (Psychomotor Activation and Euphoria) and mixed manic (Mixed Instability and Mixed Irritability) components, bearing the opportunity to identify patients with specific profiles for a better clinical and neurobiological definition.

Abstract
BACKGROUND The nosologic status of recurrent brief depression (RBD) is debated. We studied the phenomenology of RBD in a clinical sample of outpatients. METHODS Forty patients (mean age 33; 73% females) and 21 age- and gender-matched mentally healthy controls were examined (clinical interview, M.I.N.I. neuropsychiatric interview, MADRS, Stanley Foundation Network Entry Questionnaire). Exclusion criteria were bipolar I or II disorders, a history of psychosis, concurrent major depressive episode, organic brain or personality disorders (clusters A and B). RESULTS The mean age of onset of RBD was 20 years with a mean of 14 episodes/year with brief (mean 3 days) severe depressive episodes. Nineteen (47%) reported additional short episodes of brief hypomania (>1 day duration; RBD-H) of which nine (23%) never had experienced a major depression. Twenty-one (53%) patients reported RBD only (RBD-O) with or without (n=12) past history of major depression or dysthymia. During the last depressive episode, 76% of the RBD-O and 90% of the RBD-H patients had a melancholic depression. Seventy-one % of the RBD-O and 79% of the RBD-H reported at least two out of three atypical symptoms. Nineteen (48%) of the patients reported anger attacks and panic disorder, the latter being more prevalent in the RBD-H subgroup (68% versus 29%, p=0.012). LIMITATIONS Cross-sectional study of self-referrals or patients referred by primary care physicians or psychiatrists. CONCLUSIONS The study supports the validity of RBD as a disorder separate from bipolar II, cyclothymia and recurrent major depression. A brief episode of hypomanic symptoms is a severity marker of RBD.

Abstract
OBJECTIVE The aim of the study was to ascertain the clinical course of patients admitted to a psychiatric intensive care unit (PICU) just after a suicide attempt (SA) and to evaluate the effectiveness of 2nd generation antipsychotics and mood stabilizers in these patients. METHODS We examined all the 129 patients discharged in a three-year period, who had been admitted after a SA and considered in the analysis the 82 cases non-transferred (in the first 72 h) to other PICUs for administrative or logistic reasons. Among them, 47 received a complete neuropsychiatric assessment. We distinguished between patients who had been treated with Antidepressants (AD) or not in the three months preceding hospitalization. RESULTS We treated all patients with mood stabilizers and 2nd generation antipsychotics. Only one patient was treated with AD in the course of current hospitalization. Both cases treated and not treated with AD before admission improved significantly, especially in symptoms of anxiety and depression, as well as in suicidality. The suicidal risk abated without AD treatment. CONCLUSIONS In patients with impending suicide risk, AD should not be considered standard treatment. Mood stabilizers and 2nd generation antipsychotics can be effective.

Abstract
Core symptoms of depression are a combination of psychological and somatic symptoms, often combined with psychomotor and cognitive disturbances. Diagnostic classification of depression including the concepts of melancholic, endogenous, or severe depression describe severely depressed patients suffering from most of the core symptoms, together with clinical characteristics of a cyclic unipolar or bipolar course, lower placebo response rates, higher response rates to electroconvulsive therapy, to antidepressant treatments with dually or mixed modes of action, or to lithium augmentation. Higher rates ofhypothalamic-pituitary-adrenal axis hyperactivity and specific electroencephalograph patterns have also been shown in this patient group. Summarizing the symptomatology of depression in these patients, a broad overlap between the abovementioned subgroups can be suggested. Because the positive diagnosis of those core symptoms of depression may include clinical consequences, it would be of use to integrate all the mentioned concepts in the upcoming new versions of the diagnostic systems DSM-V and ICD-11.

Abstract
BACKGROUND Depressive mixed state (DMX) has been reported to be one of the most useful clinical markers for bipolar II disorder (BP-II) in the outpatient setting. However, the significance of DMX in emergency psychiatry has not been well studied. METHODS A chart review study of 139 patients who were hospitalized in an emergency psychiatric ward with an initial diagnosis of major depressive disorder (MDD). RESULTS In 42 (30.2%) patients, the diagnosis was changed to bipolar disorder after a median observation period of 189 days from hospitalization, and of these, 34 were diagnosed as having BP-II. DMX was observed in 56 (40.3%) patients at the time of hospitalization. Compared with patients who remained in MDD, significantly more patients who later developed bipolar disorder had experienced DMX (59.5% vs. 32.0%, p = 0.0044). In multivariate analysis, DMX was one of the independent predictors of conversion to bipolar disorder (OR 2.45, p = 0.037), and the independent predictors for DMX were chronic depression and atypical features (OR 2.85, p = 0.010; OR 3.67, p = 0.046, respectively). In addition, DMX was significantly more frequently observed at emergency hospitalization than at non-emergency hospitalization (48.6% vs. 29.1%, p = 0.0065). LIMITATIONS A single reviewer evaluated DMX by chart review. CONCLUSION DMX is a useful marker of bipolar disorder (mainly BP-II) in the emergency psychiatric setting and is closely related to emergency hospitalization for mood disorders. To confirm these findings, a prospective study that systematically evaluates DMX is needed.

Abstract
OBJECTIVES Community based data were used to examine the association between social phobia and comorbidity, quality of life and service utilization. In addition, the correlations of the number of social fears with these domains were studied. METHOD Data are from the Netherlands Mental Health Survey and Incidence Study (NEMESIS) (N = 7,076). Social phobia was assessed according to DSM-III-R with the Composite International Diagnostic Interview (CIDI); quality of life was assessed according to the Short-Form-36 Health Survey (SF-36). RESULTS The 12-month prevalence of social phobia was 4.8%. Being female, young, low educated, a single parent, living alone, not having a paid job and having a somatic disorder are associated with 12-month social phobia. Mean and median ages of onset of social phobia were 19.1 and 16.0 years, respectively, and mean and median duration were 16.8 and 14.0 years, respectively. 66% of respondents with social phobia had at least one comorbid condition. 12-month social phobia was significantly related to lower quality of life and higher service utilization. The mean number of feared social situations was 2.73 out of the 6 assessed. As the number of social fears increases, comorbidity and service utilization increases, and the quality of life decreases. CONCLUSIONS These findings suggest as the number of feared social situations increases, the burden of social phobia rises. In other words, like comorbidity or decreased quality of life, the number of social fears is also an important indicator of the severity of social phobia. We conclude that from a public health perspective, mental health care givers should pay attention to the number of social fears in order to check the severity of social phobia.

Abstract
BACKGROUND History of high depressive recurrence (without history of mania/hypomania) has been proposed as a mood subtype close to bipolar disorders. Herein we test whether this is the best approach to this question. METHODS We systematically evaluated consecutive 224 Major Depressive (MDD) and 336 Bipolar II Disorders (BP-II) outpatients in a private practice, by the SCID for DSM-IV (modified for better probing hypomania by Akiskal and Benazzi [Akiskal, H.S., Benazzi, F., 2005. Optimizing the detection of bipolar II disorder in outpatient private practice: toward a systematization of clinical diagnostic wisdom. J. Clin. Psychiatry 66, 914-921]). We conducted univariate and multivariate analyses on such putative bipolar validators as early age at onset of first major depressive episode (before 21 years), high recurrence, family history for bipolar disorders, and depressive mixed states (mixed depression, i.e. depression plus concurrent hypomanic symptoms), in order to identify an MDD subgroup close to BP-II. RESULTS All bipolar validators were independent predictors of BP-II. Early onset was the only variable which identified an MDD subgroup significantly associated with all bipolar validators. This MDD subgroup was similar to BP-II on age at onset and bipolar family history, and had a high frequency of mixed depression. A dose-response relationship was found between number of bipolar validators present in MDD, and bipolar family history loading among MDD relatives. LIMITATIONS Study limited to outpatients. CONCLUSIONS From among the bipolar validators, early age at onset of first major depression (<21 years) was superior to high recurrence (>4 depressive episodes) in identifying an MDD subgroup close to BP-II, which might be subsumed under the broad bipolar spectrum. Implications of unipolar-bipolar boundaries and genetic investigations are discussed.
