Effect of affective temperament on illness characteristics of subjects with bipolar disorder and major depressive disorder. J Affect Disord 2023; 334:227-237. [PMID: 37156280 DOI: 10.1016/j.jad.2023.04.130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 03/18/2023] [Accepted: 04/29/2023] [Indexed: 05/10/2023]
Abstract
BACKGROUND Affective temperaments represent the stable, biologically determined substrates of mood disorders. The relationship between affective temperaments and bipolar disorder (BD) or major depressive disorder (MDD) has been described. However, the strength of such relationship should be tested while considering other factors influencing the diagnosis of BD/MDD. Literature also lacks a comprehensive description of the interplay between affective temperament and characteristics of mood disorders. The aim of the present study is to address these issues. METHODS This is a multicentric observational study including 7 Italian university sites. Five-hundred-fifty-five euthymic subjects with BD/MDD were enrolled and further divided in those with hyperthymic (Hyper, N = 143), cyclothymic (Cyclo, N = 133), irritable (Irr, N = 49), dysthymic (Dysth, N = 155), and anxious (Anx N = 76) temperaments. Linear, binary, ordinal and logistic regressions were performed to assess the association between affective temperaments and i) diagnosis of BD/MDD; ii) characteristics of illness severity and course. RESULTS Hyper, Cyclo and Irr were more likely to be associated with BD, together with earlier age of onset and presence of a first-degree relative with BD. Anx and Dysth were more associated with MDD. Differences in association between affective temperaments and characteristics of BD/MDD were observed for hospital admissions, phase-related psychotic symptoms, length and type of depression, comorbidity and pharmacological intake. LIMITATIONS Small sample size, cross-sectional design, recall biases. CONCLUSION Specific affective temperaments were associated to certain characteristics of illness severity and course of BD or MDD. Evaluation of affective temperaments might help a deeper understanding of mood disorders.

Clinical research diagnostic criteria for bipolar illness (CRDC-BP): rationale and validity. Int J Bipolar Disord 2022; 10:23.

Abstract
BACKGROUND In the 1970 s, scientific research on psychiatric nosology was summarized in Research Diagnostic Criteria (RDC), based solely on empirical data, an important source for the third revision of the official nomenclature of the American Psychiatric Association in 1980, the Diagnostic and Statistical Manual, Third Edition (DSM-III). The intervening years, especially with the fourth edition in 1994, saw a shift to a more overtly "pragmatic" approach to diagnostic definitions, which were constructed for many purposes, with research evidence being only one consideration. The latest editions have been criticized as failing to be useful for research. Biological and clinical research rests on the validity of diagnostic definitions that are supported by firm empirical foundations, but critics note that DSM criteria have failed to prioritize research data in favor of "pragmatic" considerations. RESULTS Based on prior work of the International Society for Bipolar Diagnostic Guidelines Task Force, we propose here Clinical Research Diagnostic Criteria for Bipolar Illness (CRDC-BP) for use in research studies, with the hope that these criteria may lead to further refinement of diagnostic definitions for other major mental illnesses in the future. New proposals are provided for mixed states, mood temperaments, and duration of episodes. CONCLUSIONS A new CRDC could provide guidance toward an empirically-based, scientific psychiatric nosology, and provide an alternative clinical diagnostic approach to the DSM system.

Abstract
BACKGROUND Oxidative stress is related to the pathogenesis of mood disorders, and the level of oxidative stress may differ between bipolar disorder (BD) and major depressive disorder (MDD). This study aimed to detect the differences in non-enzymatic antioxidant levels between BD and MDD and assess the predictive values of non-enzymatic antioxidants in mood disorders by applying a machine learning model. METHODS Peripheral uric acid (UA), albumin (ALB), and total bilirubin (TBIL) were measured in 1,188 participants (discover cohort: 157 with BD and 544 with MDD; validation cohort: 119 with BD and 95 with MDD; 273 healthy controls). An extreme gradient boosting (XGBoost) model and a logistic regression model were used to assess the predictive effect. RESULTS All three indices differed between patients with mood disorders and healthy controls; in addition, the levels of UA in patients with BD were higher than those of patients with MDD. After treatment, UA levels increased in the MDD group, while they decreased in the BD group. Finally, we entered age, sex, UA, ALB, and TBIL into the XGBoost model. The area under the curve (AUC) of the XGBoost model for distinguishing between BD and MDD reached 0.849 (accuracy = 0.808, 95% CI = 0.719-0.878) and for distinguishing between BD with depression episode (BD-D) and MDD was 0.899 (accuracy = 0.891, 95% CI = 0.856-0.919). The models were validated in the validation cohort. The most important feature distinguishing between BD and MDD was UA. CONCLUSION Peripheral non-enzymatic antioxidants, especially the UA, might be a potential biomarker capable of distinguishing between BD and MDD.

Abstract
Much evidence shows that some Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5)-defined unipolar depression (UD) with bipolarity manifests bipolar diathesis. Little is known about the cognitive profiles of patients with depression with bipolarity (DWB). The study aimed to investigate the differences in cognitive profiles among patients with bipolar depression (BD), major depressive disorder (namely, UD), and DWB. Drug-naïve patients with BD, UD, and DWB and healthy controls (HC) were recruited (30 cases in each group). Cognitive function was evaluated by THINC-it (THINC-intelligent tool), Wisconsin Card Sorting Test (WCST), and continuous performance test (CPT). For THINC-it, no significant differences of the Z-scores in both objective and subjective factors were found between the DWB group and BD group, but the Z-scores in the BD group were significantly lower than those in the UD group. For WCST, significant differences were found between the BD group and DWB group in the number of responses, categories completed, trails to completed first category, perseverative responses, and perseverative errors. All the indices of WCST in the DWB group were significantly worse than those in the UD group except for trails to completed first category and total number of response correct. For CPT, only scores of leakage responses and false responses in the four-digit number in the BD group and DWB group were significantly higher than those in the UD group; no significant difference was found between the BD group and DWB group. The results indicated that patients with DWB might perform differently from those with UD but similarly to those with BD with cognition impairment.

Abstract
Depression has been widely studied by researchers from different fields, but its causes, and mechanism of action are still not clear. A difficulty emerges from the shifting from objective diagnosis or analysis to exploration of subjective feelings and experiences that influence the individuals' expression, communication and coping in facing depression. The integration of the experiential dimension of the first-person in studies on depression-and related methodological recommendations-are needed to improve the validity and generalizability of research findings. It will allow the development of timely and effective actions of care. Starting from providing a summary of the literature on theoretical assumptions and considerations for the study of the mind, with particular attention to the experiential dimension of patients with depression (aim #1 and #2), this contribution is aimed to provide practical suggestions for the design of research able to incorporate first- and third-person accounts (aim #3). It is also aimed to review qualified phenomenological methods for the acquisition and interpretation of experiential data in patients with depression (aim #4). Recognizing the first-person perspective in the study of depression is a major step toward a better understanding and treatment of this disorder. Theoretical constructs and technique suggestions that result from this review offer a valid starting point for the inclusion of the experiential dimension to common third-person research in the study of the mind.

Abstract
LEARNING OBJECTIVES After participating in this activity, learners should be better able to:• Evaluate diagnostic stability in bipolar disorder• Analyze the factors contributing to diagnostic stability OBJECTIVE: Diagnostic stability is the degree to which a diagnosis remains unchanged during follow-up. It is an important measure of predictive validity in bipolar disorder (BD). In this study, we review the literature concerning diagnostic stability in BD, analyze the factors contributing to diagnostic stability, and describe the implications of diagnostic boundaries and diagnostic delay. METHODS A comprehensive literature search of MEDLINE and EMBASE databases was conducted, including all studies published from 1980 to 2016, to evaluate the diagnostic stability of BD. Thirty-seven articles were included: 6 focusing mainly on BD, 18 on psychotic disorders, 10 on depression, and 3 on diagnostic stability in psychiatric disorders in general. Data analysis was performed in standardized fashion using a predefined form. RESULTS Despite a high variability of the methodological approaches taken, an acceptable degree of diagnostic stability was found. The most common criteria for evaluating diagnostic stability were prospective consistency and retrospective consistency. The mean prospective and retrospective consistencies were 77.4% and 67.6%, respectively. A large majority of studies were performed in Europe or in North America (67.5%), compared to 21.6% in Asia and only 10.8% in Africa, Oceania, and South America. Extreme ages, female gender, psychotic symptoms, changes to treatment, substance abuse, and family history of affective disorder have been related to diagnostic instability. CONCLUSIONS Several factors appear to have a negative impact on the diagnostic stability, but the evidence is insufficient to draw any robust conclusions. Nevertheless, despite variable prospective and retrospective consistencies, the overall diagnostic stability is good. Standardized methods need to be used to obtain more accurate assessments of stability.

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

Abstract
BACKGROUND AND OBJECTIVES Bipolar spectrum disorder (BSD) is an extended concept of bipolar disorder (BD) that includes conditions that do not fulfill the criteria. There is no recommendation today about its treatment. We reviewed relevant literature focusing on pharmacological treatments, looking for high-strength evidence leading to guidelines. METHODOLOGY A literature search was conducted using MedLine / PubMed database and Google Scholar up to September 2018. Search words were related to BSD and pharmacological treatment. RESULTS The literature search yielded 621 articles. Out of these, 35 articles met our selection criteria. There was limited high quality data. Only one randomized control trial (RCT) and one randomized open label trial were found. Most studies used different definition of BSD. CONCLUSIONS There is a considerable lack of data and no evidence supporting efficacy of pharmacological treatment for BSD. There is a need for a consensus on the definition of BSD and more evidence studies to evaluate drug's effectiveness in this condition.

Abstract
BACKGROUND This study, for the first time, compared illness and antidepressant response characteristics of young subjects with major depression (MDD) at low (LRMDD) or high-risk (HRMDD) for developing bipolar disorder with characteristics of young bipolar (BPD) subjects and healthy controls (HC). METHODS One hundred and six young (15-30 yr), medication-free subjects MDD subjects (HRMDD, N = 51; LRMDD, N = 55) were compared with 32 BPD (Type I: 14; Type II: 18) as well as 49 HC subjects. Baseline illness characteristics and frequency of comorbid conditions were examined using Analysis of Variance and Cochran-Armitage trend test. Additionally, in MDD subjects, the effect of open-label antidepressant treatment for up to 24 months with periodic assessments was compared between HRMDD and LRMDD groups for treatment response, remission and (hypo)mania switch while controlling for attrition. RESULTS Significant gradation from LRMDD to HRMDD to BPD groups was found for increasing occurrence of alcohol dependence (p = 0.006), comorbid PTSD (p = 0.006), borderline personality traits (p = 0.001), and occurrence of melancholic features (p < 0.005). Antidepressant treatment response was similar between the two groups except that for the 12-month period HRMDD showed a trend for a lower response. Switch to (hypo)mania was infrequent in both groups though the HRMDD showed a higher occurrence of spikes in (hypo)mania symptoms (>25% increase in YMRS scores)(p = 0.04). CONCLUSION Findings of the study indicate that a substantial proportion of young MDD subjects share BPD illness characteristics. These HRMDD subjects, if treated with antidepressants, need to be monitored for development of BPD. TRIAL REGISTRATION NCT01811147.

Abstract
INTRODUCTION Subthreshold presentations of bipolarity (BSPs) pose a diagnostic conundrum, in terms of whether they should be conceptualized and treated similarly as traditionally defined bipolar disorders (BD). While it has been argued that BSPs are on a pathophysiologic continuum with traditionally defined BDs, there has been limited examination of biological and objective markers in these presentations to validate this assertion. Areas covered: The authors review studies examining genetic, neurobiological, cognitive and peripheral markers in BSPs, encompassing clinical and non-clinical populations with subthreshold hypo/manic symptoms. Results are placed in the context of previously identified markers in traditionally defined BDs. Expert commentary: There have been few studies of objective and biological markers in subthreshold presentations of BD, and results are mixed. While abnormalities in brain structure/functioning, peripheral inflammatory, and cognitive markers have been reported, it is unclear whether these findings are specific to BD or indicative of broad affective pathology. However, some studies suggest that increased sensitivity to reward and positive stimuli are shared between subthreshold and traditionally defined BDs, and may represent a point of departure from unipolar major depression. Further examination of such markers may improve understanding of subthreshold bipolar presentations, and provide guidance in terms of therapeutic strategies.

Abstract
Major affective conditions including both unipolar (UD) and bipolar disorders (BD) are associated with significant disability throughout the life course. We aimed to investigate the most relevant socio-demographic/clinical differences between UD and BD subjects. Our sample included 180 inpatients, of which 82 (45.5%) participants were diagnosed with UD and 98 (54.5%) with BD. Relative to UD patients, BD individuals were more likely to report prior psychoactive medications, lifetime psychotic symptoms, nicotine abuse, a reduced ability to provide to their needs, gambling behavior, and fewer nonsuicidal self-harm episodes. Moreover, BD patients were more likely to report severe side effects related to medications, a younger age at illness onset and first hospitalization, higher illness episodes, and longer illness duration in years than UD subjects. In a multivariate logistic analysis accounting for age, gender, and socio-demographic characteristics, a significant positive contribution to bipolarity was found only for higher lifetime psychotic symptoms (β = 1.178; p ≤ .05) and number of illness episodes (β = .155; p ≤ .05). The present findings suggest that specific clinical factors may be used in order to better distinguish between UD and BD subgroups. Further studies are required to replicate these findings in larger samples.

Abstract
OBJECTIVE A diagnosis of bipolar disorder (BD) is often preceded by an initial diagnosis of depression, creating a delay in the accurate diagnosis and treatment of BD. Although previous research has focused on predictors of a diagnosis change from depression to BD, the research on this delay in diagnosis is sparse. Therefore, the present study examined the time taken to make a BD diagnosis following an initial diagnosis of major depressive disorder in order to further understand the patient characteristics and psychological factors that may explain this delay. METHOD A total of 382 patients underwent a clinical evaluation by a psychiatrist and completed a series of questionnaires. RESULTS Ninety patients were initially diagnosed with depression with a later diagnosis of BD, with a mean delay in diagnostic conversion of 8.74 years. These patients who were later diagnosed with BD were, on average, diagnosed with depression at a younger age, experienced more manic symptoms, and had a more open personality style and better coping skills. Cox regressions showed that depressed patients with diagnoses that eventually converted to BD had been diagnosed with depression earlier and that this was related to a longer delay to conversion and greater likelihood of dysfunctional attitudes. CONCLUSION The findings from the present study suggested that an earlier diagnosis of depression is related to experiencing a longer delay in conversion to BD. The clinical implications of this are briefly discussed, with a view to reducing the seemingly inevitable delay in the diagnosis of BD.

Abstract
Mixed affective states, defined as the coexistence of depressive and manic symptoms, are complex presentations of manic-depressive illness that represent a challenge for clinicians at the levels of diagnosis, classification, and pharmacological treatment. The evidence shows that patients with bipolar disorder who have manic/hypomanic or depressive episodes with mixed features tend to have a more severe form of bipolar disorder along with a worse course of illness and higher rates of comorbid conditions than those with non-mixed presentations. In the updated Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5), the definition of "mixed episode" has been removed, and subthreshold nonoverlapping symptoms of the opposite pole are captured using a "with mixed features" specifier applied to manic, hypomanic, and major depressive episodes. However, the list of symptoms proposed in the DSM-5 specifier has been widely criticized, because it includes typical manic symptoms (such as elevated mood and grandiosity) that are rare among patients with mixed depression, while excluding symptoms (such as irritability, psychomotor agitation, and distractibility) that are frequently reported in these patients. With the new classification, mixed depressive episodes are three times more common in bipolar II compared with unipolar depression, which partly contributes to the increased risk of suicide observed in bipolar depression compared to unipolar depression. Therefore, a specific diagnostic category would imply an increased diagnostic sensitivity, would help to foster early identification of symptoms and ensure specific treatment, as well as play a role in suicide prevention in this population.

Abstract
BACKGROUND The Temperament Evaluation Memphis, Pisa, Paris and San Diego Auto-questionnaire (TEMPS) is validated to assess temperament in clinical and non-clinical samples. Scores vary across bipolar disorder (BD), major depressive disorder (MDD), attention-deficit/hyperactivity disorder (ADHD), borderline personality disorder (BPD) and healthy controls (HCs), but a meta-analysis is missing. METHODS Meta-analysis of studies comparing TEMPS scores in patients with mood disorders or their first-degree relatives to each other, or to a psychiatric control group or HCs. RESULTS Twenty-six studies were meta-analyzed with patients with BD (n= 2025), MDD (n=1283), ADHD (n=56) and BPD (n=43), relatives of BD (n=436), and HCs (n=1757). Cyclothymic (p<0.001) and irritable TEMPS scores (p<0.001) were higher in BD than MDD (studies=12), and in MDD vs HCs (studies=8). Cyclothymic (p<0.001), irritable (p<0.001) and anxious (p=0.03) scores were higher in BD than their relatives, who, had higher scores than HCs. No significant differences emerged between ADHD and BD (studies=3); CONCLUSION Affective temperaments are on a continuum, with increasing scores ranging from HCs through MDD to BD regarding cyclothymic and irritable temperament, from MDD through BD to HC regarding hyperthymic temperament, and from HC through BD relatives to BD regarding cyclothymic, irritable and anxious temperament. Depressive and anxious temperaments did not differ between BD and MDD, being nonetheless the lowest in HCs. BD did not differ from ADHD in any investigated TEMPS domain. LIMITATIONS Different TEMPS versions, few studies comparing BD with ADHD or BPD, no correlation with other questionnaires.

Abstract
Bipolar disorder constitutes a challenge for clinicians in everyday clinical practice. Our knowledge concerning this clinical entity is incomplete, and contemporary classification systems are unable to reflect the complexity of this disorder. The concept of temperament, which was first described in antiquity, provides a helpful framework for synthesizing our knowledge on how the human body works and what determines human behavior. Although the concept of temperament originally included philosophical and sociocultural approaches, the biomedical model is dominant today. It is possible that specific temperaments might constitute vulnerability factors, determine the clinical picture, or modify the course of illness. Temperaments might even act as a bridge between genes and clinical manifestations, thus giving rise to the concept of the bipolar spectrum, with major implications for mental health research and treatment. More specifically, it has been reported that the hyperthymic and the depressive temperaments are related to the more "classic" bipolar disorder, whereas cyclothymic, anxious, and irritable temperaments are related to more complex manifestations and might predict poor response to treatment, violent or suicidal behavior, and high comorbidity. Incorporating of the concept of temperament and the bipolar spectrum into the standard training of psychiatric residents might well result in an improvement of everyday clinical practice.

Abstract
BACKGROUND The Bipolarity Index is a clinician-rated scale that rates cardinal features of the disorder across five domains: signs and symptoms, age of onset, course of illness, response to treatment, and family history. We tested the Index in routine clinical practice to identify the optimal cut-off for distinguishing bipolar from non-bipolar disorders. METHOD Sequential patients in a private practice were rated with the Bipolarity Index (n=1903) at intake. Diagnoses were made with the MINI-6.0.0 International Neuropsychiatric Interview according to DSM-IV-TR criteria, except that cases of antidepressant-induced mania and hypomania were included in the bipolar group. A subset completed the self-rated Mood Disorder Questionnaire (MDQ) (n=1620) or Bipolar Spectrum Diagnostic Scale (BSDS) (n=1179). The primary analysis compared Bipolarity Index scores for bipolar vs. non-bipolar patients using receiver operator curves (ROC) to determine the optimal cut-off score. Secondary outcomes repeated this analysis with the MDQ, MDQ-7 (using only the symptomatic items of the MDQ) and BSDS. RESULTS At a cut-off of ≥50, the Bipolarity Index had a high sensitivity (0.91) and specificity (0.90). Optimal cut-offs for self-rated scales were: MDQ: ≥7 (sensitivity 0.74, specificity 0.71); MDQ-7: ≥6 (sensitivity 0.77, specificity 0.77); BSDS: ≥12 (sensitivity 0.71, specificity 0.77). LIMITATIONS The study utilized one rater at a single practice site; the rater was not blinded to the results of the MINI. CONCLUSION The Bipolarity Index can enhance the clinical assessment of mood disorders and, at a score ≥50 has good sensitivity and specificity for identifying bipolar disorders.

Abstract
OBJECTIVES There is much evidence that shows that a substantial number of individuals with DSM-IV-defined unipolar depression (UP) manifest hypomanic sub-syndrome and bipolar diathesis. Other definitions have conceptualized the term soft bipolar spectrum (SBP) for these individuals. Little is known about the cognitive profiles of individuals with SBP. We hypothesized that they are representative of individuals with bipolar II disorder and are different from that of 'strict' UP. METHODS Consecutive referrals suffering major depressive episodes were categorically assigned to groups of either bipolar I disorder (n = 98), bipolar II disorder (n = 138), or UP (n = 300). Based on the SBP criteria by Akiskal and Pinto (17), patients with UP were subdivided into 81 SBP and 219 strict UP. We administered self- and clinician-administered scales to evaluate affective temperaments, and neuropsychological tests to assess seven cognitive domains. RESULTS Patients with SBP performed significantly better than strict UP patients in the domains of processing speed (p = 0.002), visual-spatial memory (p = 0.017), and verbal working memory (p = 0.017). Compared to patients with bipolar I disorder, patients with SBP were significantly better in set shifting (p < 0.001) and visual-spatial memory (p = 0.042). Patients with SBP performed similarly to patients with bipolar II disorder in all of the cognitive domains tested (p > 0.05). There was a group × cognitive domain interaction effect between bipolar I disorder, bipolar II disorder, SBP, and strict UP groups [Pillai's F = 2.231, df = (18,1437), p = 0.002]. CONCLUSIONS Our data suggest that patients with SBP differ from patients with UP not only in external validators (e.g., family history of bipolar disorder) and hypomanic symptoms, but also in neuropsychological performance and that the profiles of cognitive functioning were different across bipolar I disorder and 'bipolar II spectrum' that subsumes bipolar II disorder and SBP.

Abstract
Borderline personality disorder (BPD) and bipolar disorder (types I and II) are frequently confused because of their symptomatic overlap. Although affective instability is a prominent feature of each, the pattern is entirely different. BPD is characterized by transient mood shifts that occur in response to interpersonal stressors, whereas bipolar disorder is associated with sustained mood changes. These disorders can be further distinguished by comparing their phenomenology, etiology, family history, biological studies, outcome, and response to medication. Their distinction is of great clinical importance because misdiagnosis can deprive the patient of potentially effective treatment, whether it is psychotherapy for BPD or medication for bipolar disorder. On the basis of a comprehensive literature review, guidelines for differential diagnosis are suggested, and priorities for further research are recommended.

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
Classical concepts of bipolarity (bipolar I and bipolar II) have sometimes been extended into a broader spectrum that includes a wide variety of conditions previously diagnosed as separate forms of psychopathology. Differential diagnosis remains important, particularly in personality disorders characterized by affective instability, and in behavior disorders affecting pre-pubertal children. In the absence of biological markers or other external sources of validity, as well as lack of evidence for response to pharmacological treatment when disorders are defined more broadly, the bipolar spectrum remains an unproven hypothesis.

Abstract
OBJECTIVES The prevalence of bipolar II disorder (BD-II) in Russia has never been studied. Therefore, we sought to identify patients meeting diagnostic criteria for BD-II among patients with a current diagnosis of recurrent depressive disorder (RDD) through the use of the Russian versions of the Hypomania Checklist (HCL-32) and Bipolarity Index scales for differentiating between BD-II and RDD. METHODS In a non-interventional diagnostic study, we selected 409 patients aged between 18 and 65 years from two medical settings with (i) a current diagnosis of RDD, (ii) an illness duration of at least three years, and (iii) at least two affective episodes. The diagnosis was based on clinical assessment and confirmed by the Russian version of the Mini International Neuropsychiatric Interview. All patients were assessed by the HCL-32, the Bipolarity Index, and the Personal and Social Performance Scale. RESULTS Among patients with a current diagnosis of RDD, 40.8% had a diagnosis of bipolar disorder (bipolar I disorder: 4.9%; BD-II: 35.9%). The average time lag from onset to a correct diagnosis of BD-II was 15 years and patients were treated only with antidepressants. The sensitivity of the Russian version of the HCL-32 at the optimal cutoff point (≥14.0) was 83.7%, and its specificity was 71.9%. The Bipolarity Index showed significant differences between the total scores of the patients with BD-II and RDD (31.8 versus 20.2; p < 0.0001). The optimal threshold was ≥22.0 (sensitivity 73.5%; specificity 72.3%). CONCLUSIONS In Russia, diagnostic errors are an important cause of the non-detection of bipolar disorder, particularly BD-II. The Russian version of the HCL-32 and the Bipolarity Index, as additional tools, could be useful for bipolarity screening.

Abstract
First-line treatment of major depression includes administration of a selective serotonin reuptake inhibitor (SSRI), yet studies suggest that remission rates following two trials of an SSRI are <50%. The authors examine the putative biological substrates underlying "treatment resistant depression (TRD)" with the goal of elucidating novel rationales to treat TRD. We look at relevant articles from the preclinical and clinical literature combined with clinical exposure to TRD patients. A major focus was to outline pathophysiological mechanisms whereby the serotonin system becomes impervious to the desired enhancement of serotonin neurotransmission by SSRIs. A complementary focus was to dissect neurotransmitter systems, which serve to inhibit the dorsal raphe. We propose, based on a body of translational studies, TRD may not represent a simple serotonin deficit state but rather an excess of midbrain peri-raphe serotonin and subsequent deficit at key fronto-limbic projection sites, with ultimate compromise in serotonin-mediated neuroplasticity. Glutamate, serotonin, noradrenaline, and histamine are activated by stress and exert an inhibitory effect on serotonin outflow, in part by "flooding" 5-HT1A autoreceptors by serotonin itself. Certain factors putatively exacerbate this scenario - presence of the short arm of the serotonin transporter gene, early-life adversity and comorbid bipolar disorder - each of which has been associated with SSRI-treatment resistance. By utilizing an incremental approach, we provide a system for treating the TRD patient based on a strategy of rescuing serotonin neurotransmission from a state of SSRI-induced dorsal raphe stasis. This calls for "stacked" interventions, with an SSRI base, targeting, if necessary, the glutamatergic, serotonergic, noradrenergic, and histaminergic systems, thereby successively eliminating the inhibitory effects each are capable of exerting on serotonin neurons. Future studies are recommended to test this biologically based approach for treatment of TRD.

Abstract
OBJECTIVE This review aims to address concerns about the potential overinclusiveness and vagueness of bipolar spectrum concepts, and also, concerns about the overlap between bipolar illness and borderline personality. METHOD Narrative review based on historical and empirical studies. RESULTS Bipolar disorder (BD) and major depressive disorder (MDD) came to be separate entities with the Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM III), in contrast to the Kraepelinian manic-depressive insanity (MDI) concept, which included both. The bipolar spectrum concept is a return to this earlier Kraepelinian perspective. Further, very different features differentiate the disease of bipolar illness (family history of bipolar illness, severe recurrent mood episodes with psychomotor activation) from the clinical picture of borderline personality (dissociative symptoms, sexual trauma, parasuicidal self-harm). The term 'disorder' obfuscates an ontological difference between diseases, such as manic-depressive illness, and clinical pictures, such as hysteria/post-traumatic stress disorder/dissociation/borderline personality. CONCLUSIONS Bipolar spectrum concepts are historically rooted in Kraepelin's manic-depressive illness concept, are scientifically testable, and can be clearly formulated. Further, they differ in kind from traumatic/dissociative conditions in ways that can be both historically and scientifically established.

Abstract
Background:Undiagnosed and therefore inadequately treated hypomanic symptoms may be a leading cause of drug resistance in depression diagnosed as unipolar (major depressive disorder, MDD). The purpose of the IMPROVE study was to identify the rate of misdiagnoses in patients with treatment-resistant MDD by screening for the presence of previous hypomanic episodes, and to study the characteristics of those patients with a positive history of hypomania. Methods:Patients attending 29 psychiatric units throughout Italy with a diagnosis of MDD who were resistant to anti-depressant treatment were included in this multicentre, observational single visit study. The Hypomania Checklist 32 (HCL-32) was administered to detect underlying bipolarity. Results: Among the 466 enrolled patients, 256 (57.40%) were positive at screening for a previous hypomanic episode (HCL-32 ≥12), therefore suggesting a misdiagnosis. These patients scored higher than those with a negative history in both the “active/elated hypomania” (11.27±3.11 vs 3.57±3.05; P<0.0001) and “irritable/risk-taking hypomania” (2.87±2.03 vs 2.06±1.73; P<0.001) HCL-32 sub-scales. Patients with a positive history of hypomania were younger, had a higher number of previous depressive episodes and a higher frequency of comorbid conditions compared to those with a negative history. Conclusions:This study suggests that screening for hypomania in MDD-resistant patients facilitates identification of a notable proportion of undiagnosed cases of bipolar spectrum disorder. Patients with a positive history of hypomania at screening had a demographic/clinical bipolar-like profile that included young age, higher number of previous depressive episodes and higher frequency of comorbid conditions. They also had both higher active and irritable hypomania symptom scores.

Abstract
PURPOSE Despite a growing body of knowledge on bipolar spectrum disorder (BSD), relatively little is known about the clinical characteristics of BSD in elderly people. We investigated the prevalence of BSD in elderly patients with recurrent depression. PATIENTS AND METHODS A total of 65 elderly outpatients (≥60 years of age) who met the Diagnostic and Statistical Manual of Mental Disorders IV criteria for recurrent major depressive disorder participated in the study. BSD was diagnosed according to the criteria developed by Ghaemi et al and the Mood Disorder Questionnaire (MDQ) was used to assess bipolarity. RESULTS Of 65 subjects, eleven (16.9%) and 54 (83.1%) were diagnosed with BSD and unipolar depression, respectively. A total of 32.3% (n=22) had a positive screen for bipolar disorder, and we found a significant association between the BSD criteria and the criteria for a positive MDQ (P<0.001). Patients with BSD had a longer duration of illness (P=0.040) and more prior depressive episodes (P<0.001) than did those with unipolar depression. The BSD criteria of first-degree relative with bipolar disorder (P=0.030), antidepressant-induced hypomania (P=0.034), hyperthymic personality (P=0.001), and atypical depression (P=0.030) were highly associated with MDQ-positive patients. CONCLUSION Our results indicate that many depressed elderly patients have bipolar-related illness; moreover, some features of the depression are associated with bipolarity.

J Affect Disord 2013; 151:540-550. [PMID: 23856282 DOI: 10.1016/j.jad.2013.06.041] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2013] [Revised: 06/17/2013] [Accepted: 06/17/2013] [Indexed: 12/12/2022]
Abstract
BACKGROUND The aim of this study was to assess whether different affective temperaments could be related to a specific mood disorder diagnosis and/or to different therapeutic choices in inpatients admitted for an acute relapse of their primary mood disorder. METHOD Hundred and twenty-nine inpatients were consecutively assessed by means of the Structured and Clinical Interview for axis-I disorders/Patient edition and by the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego auto-questionnaire, Young Mania Rating Scale, Hamilton Scale for Depression and for Anxiety, Brief Psychiatry Rating Scale, Clinical Global impression, Drug Attitude Inventory, Barratt Impulsiveness Scale, Toronto Alexithymia Scale, and Symptoms Checklist-90 items version, along with records of clinical and demographic data. RESULTS The following prevalence rates for axis-I mood diagnoses were detected: bipolar disorder type I (BD-I, 28%), type II (31%), type not otherwise specified (BD-NOS, 33%), major depressive disorder (4%), and schizoaffective disorder (4%). Mean scores on the hyperthymic temperament scale were significantly higher in BD-I and BD-NOS, and in mixed and manic acute states. Hyperthymic temperament was significantly more frequent in BD-I and BD-NOS patients, whereas depressive temperament in BD-II ones. Hyperthymic and irritable temperaments were found more frequently in mixed episodes, while patients with depressive and mixed episodes more frequently exhibited anxious and depressive temperaments. Affective temperaments were associated with specific symptom and psychopathology clusters, with an orthogonal subdivision between hyperthymic temperament and anxious/cyclothymic/depressive/irritable temperaments. Therapeutic choices were often poorly differentiated among temperaments and mood states. LIMITS Cross-sectional design; sample size. CONCLUSIONS Although replication studies are needed, current results suggest that temperament-specific clusters of symptoms severity and psychopathology domains could be described.

Abstract
Psychiatry has long been prone to fads. The main reason is that mental illness is poorly understood and can be difficult to treat. Most diagnostic fads have involved the extension of well-known categories into broader spectra. The most prominent treatment fads have involved the overuse of pharmacological interventions and a proliferation of methods for psychotherapy. The best antidote to fads is a commitment to evidence-based psychiatry.

Abstract
OBJECTIVES The objectives were to assess the characteristics of patients with bipolar disorder (BD) and to evaluate the prescribing practices. METHODS MONTRA is a quantitative survey conducted between December 2010 and February 2011. Data were extracted by the psychiatrists from the medical files of BD patients seen on four consecutive days of consulting. RESULTS Four hundred and thirty-nine psychiatrists included 2529 patients (inpatients, n=319; outpatients from mental clinics, n=1090; outpatients consulting in private practice, n=1020). In the total patient population (mean age: 47 years; women, 58%), BD was distributed as follows: BD type I, 56%; BD type II, 40%; other types of BD, 4%; rapid cyclers, 10%. The prevalence of psychiatric comorbidities was high (anxiety disorders, 48%; abuse and dependence on toxic substances, 17 and 10% respectively), 36% of the patients had a history of suicide attempt and the risk of suicide, when assessed, was 6%. In about half the patients (48%), the polarity of the initial bipolar episode was of the depressive type (versus 39% for the manic/hypomanic type). Outpatients were globally independent and did not require assistance in the management of their disease or its treatment whereas the social and professional lives of inpatients were negatively affected by their condition. Based on the psychiatrist's declarations, 39 to 50% of the outpatients were symptom-free, 36 to 40% were in the intercurrent phase with residual symptoms, 11 to 17% presented either a manic or depressive acute BP episode, and 3 to 4% were in a mixed state; among inpatients, 52% presented an acute episode either manic or depressive, 38% were in the intercurrent phase and 9% were in a mixed state. In the symptomatic patients from the total population (61%), the most prevalent symptoms were depressive and corresponded to acute symptoms (patients with a depressive episode, 14%) or residual symptoms (patients in the intercurrent phase, 27%). The predominant depressive polarity was observed in both hospitalized and outpatients. The pharmacological treatment of BD included polytherapy in 73% of the patients. In the manic episodes (n=126), the patients were treated with a Mood Stabilizer (MS, 56%) or an atypical antipsychotic (AAP, 52%) in association. In the depressive episodes (n=342), the patients received an antidepressant drug associated with a MS or an AAP (70%). In symptom-free or symptomatic intercurrent periods (n=1943), the patients were treated with a MS (49-58%) or an AAP (37-49%), in association. CONCLUSION BD patients evaluated in our survey were in majority diagnosed with BD type I, associated with considerable comorbidity. In the symptomatic patients, the most prevalent symptoms, either acute or residual, were of the depressive type. In the majority of the patients, whatever the clinical status, polytherapy was prescribed for the BD.

A comprehensive analysis of features that suggest bipolarity in patients with a major depressive episode: which is the best combination to predict soft bipolarity diagnosis? J Affect Disord 2013; 147:150-5. [PMID: 23158958 DOI: 10.1016/j.jad.2012.10.026] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2012] [Accepted: 10/23/2012] [Indexed: 11/23/2022]
Abstract
BACKGROUND The study aimed to identify specific predictors of soft bipolarity (bipolar II disorder or bipolar disorder not otherwise specified) in depressed patients and to evaluate the global predictive performance of combinations of these predictors. METHODS Subjects included 199 patients with a major depressive episode (MDE) due to soft bipolarity or major depressive disorder. Independent predictors of soft bipolar diagnosis were extracted from 12 previously proposed bipolar features using multiple logistic regression analyses, and the global performance of the combination of these predictors was evaluated using a receiver operating characteristic (ROC) curve. RESULTS Recurrent MDEs, family history of bipolar disorders in first-degree relatives, cyclothymic temperament, early age at onset of first MDE, and depressive mixed state were independent predictors of soft bipolarity diagnosis [odds ratio (95% confidence interval): 11.22 (2.19-57.63), 8.82 (1.31-59.15), 7.32 (2.22-24.19), 6.22 (1.58-24.57), and 5.57 (1.91-16.30), respectively]. The area under the ROC curve for the relationship between soft bipolarity diagnosis and the number of these five predictors in each patient was 0.911 (highly accurate). The presence of one or more predictors in each patient resulted in highest sensitivity (92.5%) and good specificity (73.1%), whereas that of two or more predictors resulted in good sensitivity (70.0%) and highest specificity (97.5%) for soft bipolarity diagnosis. LIMITATIONS Structured/semistructured interviews were not used. Tools for temperament assessments were different between institutions. CONCLUSIONS A combination of these predictors was quite helpful for a precise diagnosis of soft bipolarity in patients with depression.

Abstract
BACKGROUND The aim of the study was to check the stability of a diagnosis of major depressive disorder (MDD) in an outpatient setting, as well as to assess the scope of diagnostic conversions into bipolar disorder (BD). METHODS Retrospective chart review of 122 patients with a primary diagnosis of MDD. RESULTS Diagnostic conversion from MDD into BD was noticed in 40 subjects (32.8%), 25 patients (20.5%) were treatment-resistant. Mean time to the conversion was 9.27±8.64 years. A negative correlation between the age of illness onset and time to diagnostic conversion was observed (-0.41; p<0.05). Earlier onset of MDD was associated with higher risk of diagnostic conversion (<30vs≥30 years of age at onset: 69% vs 28%, p=0.0001; <35vs≥35 years of age: 50% vs 25%, p=0.0065). Treatment-resistance was more prevalent in the BD conversion group (40% vs 11%; p=0.0002). Diagnostic conversion into BD was also related longer duration of treatment received, higher number of illness episodes, and higher number of hospitalizations. LIMITATIONS Retrospective design of the study. CONCLUSIONS The problem of diagnosis evolution from MDD to BD was observed in about 1/3 of patients, and was associated with treatment-resistance of depression, earlier onset of depression, longer time of treatment, higher number of depressive episodes and hospitalizations. The variables above may be a useful predictor of bipolar diathesis.

Abstract
BACKGROUND Recent reports indicate that the prevalence of bipolar disorder (BD) in patients with an acute major depressive episode might be higher than previously thought. We aimed to study systematically all patients who sought therapy for major depressive episode (MDE) within the BRIDGE study in Germany, reporting on an increased number (increased from 2 in the international BRIDGE report to 5) of different diagnostic algorithms. METHODS A total of 252 patients with acute MDE (DSM-IV confirmed) were examined for the existence of BD (a) according to DSM-IV criteria, (b) according to modified DSM-IV criteria (without the exclusion criterion of 'mania not induced by substances/antidepressants'), (c) according to a Bipolarity Specifier Algorithm which expands the DSM-IV criteria, (d) according to HCL-32R (Hypomania-Checklist-32R), and (e) according to a criteria-free physician's diagnosis. RESULTS The five different diagnostic approaches yielded immensely variable prevalences for BD: (a) 11.6; (b) 24.8%; (c) 40.6%; (d) 58.7; e) 18.4% with only partial overlap between diagnoses according to the physician's diagnosis or HCL-32R with diagnoses according to the three DSM-based algorithms. CONCLUSIONS The diagnosis of BD in patients with MDE depends strongly on the method and criteria employed. The considerable difference between criteria-free physician's diagnosis and the remaining algorithms indicate the usefulness of criteria lists within the everyday clinical setting. LIMITATIONS Diagnoses based on DSM were only made with checklists. The diagnoses of (hypo-) manic episodes in the patient history were not systematically verifiable by indirect anamnesis.

Abstract
Cyclothymic disorder is a chronic and impairing subtype of bipolar disorder, largely neglected in pediatric research. Consequently, it is rarely diagnosed clinically despite potentially being the most prevalent form of bipolar disorder. Lack of attention has added to confusion about the diagnosis and clinical presentation of cyclothymic disorder. In pediatric studies, cyclothymic disorder is commonly grouped with 'subthreshold' presentations of bipolar disorder under the undifferentiated label 'bipolar disorder not otherwise specified'. However, research indicates that cyclothymic disorder can be reliably distinguished from the other forms of bipolar disorder and from other childhood disorders. Importantly, cyclothymic disorder may be a diathesis for more acute presentations of bipolar disorder, warranting a prominent role in dimensional models of mood and psychopathology. Current evidence suggests that cyclothymic disorder has the potential to make unique contributions to our understanding of the risk factors and outcomes associated with bipolar disorder. This potential has yet to be fully realized, limiting our knowledge and ability to intervene in a meaningful way with youth who are exhibiting symptoms of a major mood disorder. Including cyclothymic disorder in future research studies of children - particularly longitudinal outcome studies - is essential for understanding the developmental trajectory of bipolar spectrum disorders and learning how to accurately diagnosis and treat the full spectrum of bipolar disorders.

Abstract
BACKGROUND Research suggests that current diagnostic criteria for bipolar disorders may fail to include milder, but clinically significant, bipolar syndromes and that a substantial percentage of these conditions are diagnosed, by default, as unipolar major depression. Accordingly, a number of researchers have argued for the upcoming 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to better account for subsyndromal hypomanic presentations. METHODS The present paper is a critical review of research on subthreshold bipolarity, and an assessment of some of the challenges that researchers and clinicians might face if the DSM-5 were designed to systematically document subsyndromal hypomanic presentations. RESULTS Individuals with major depressive disorder (MDD) who display subsyndromal hypomanic features, not concurrent with a major depressive episode, have a more severe course compared to individuals with MDD and no hypomanic features, and more closely resemble individuals with bipolar disorder on a number of clinical validators. CONCLUSION There are clinical and scientific reasons for systematically documenting subsyndromal hypomanic presentations in the assessment and diagnosis of mood disorders. However, these benefits are balanced with important challenges, including (i) the difficulty in reliably identifying subsyndromal hypomanic presentations, (ii) operationalizing subthreshold bipolarity, (iii) differentiating subthreshold bipolarity from borderline personality disorder, (iv) the risk of over-diagnosing bipolar spectrum disorders, and (v) uncertainties about optimal interventions for subthreshold bipolarity.

Abstract
BACKGROUND Recent studies have suggested that clinicians may under diagnose bipolarity in a substantial proportion of depressive patients, and proposed that affective temperaments particularly cyclothymic temperament (CT), may predict bipolarity in these patients. The objectives of this study were to assess CT in patients with recurrent depressive disorder (RDD) and to explore its associations with clinical predictors of bipolarity. METHODS 98 patients (43 men and 55 women, mean age=46.8±9.9years), followed for RDD according to DSM-IV-TR criteria, were recruited. CT was assessed using the Tunisian version of the TEMPS cyclothymic subscale with the threshold score of 10/21. RESULTS The mean score of CT was 6.5±5.2. One-third of patients (33.7%) had a CT score ≥10. These patients with high CT scores had significantly early age at onset of first depressive episode and high number of previous depressive episodes, and had more psychotic and melancholic features and suicidal ideations and attempts during the last depressive episode compared to patients with low CT scores. The multiple regression analysis showed an association between CT scores and psychotic, melancholic and atypical features and suicide attempts during the last depressive episode. LIMITATIONS This is a cross-sectional study with a relatively small number of patients. The Tunisian version of the CT subscale was not yet validated. CONCLUSIONS CT was associated with some clinical predictive factors of bipolarity. These results suggest the relevance of the CT screening in RDD, considering the change of polarity risk and misdiagnosis of unipolar depression.

Abstract
CONTEXT It has been suggested that patients with major depressive disorder (MDD) who display pretreatment features suggestive of bipolar disorder or bipolar spectrum features might have poorer treatment outcomes. OBJECTIVE To assess the association between bipolar spectrum features and antidepressant treatment outcome in MDD. DESIGN Open treatment followed by sequential randomized controlled trials. SETTING Primary and specialty psychiatric outpatient centers in the United States. PARTICIPANTS Male and female outpatients aged 18 to 75 years with a DSM-IV diagnosis of nonpsychotic MDD who participated in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study. INTERVENTIONS Open treatment with citalopram followed by up to 3 sequential next-step treatments. MAIN OUTCOME MEASURES Number of treatment levels required to reach protocol-defined remission, as well as failure to return for the postbaseline visit, loss to follow-up, and psychiatric adverse events. For this secondary analysis, putative bipolar spectrum features, including items on the mania and psychosis subscales of the Psychiatric Diagnosis Screening Questionnaire, were examined for association with treatment outcomes. RESULTS Of the 4041 subjects who entered the study, 1198 (30.0%) endorsed at least 1 item on the psychosis scale and 1524 (38.1%) described at least 1 recent maniclike/hypomaniclike symptom. Irritability and psychoticlike symptoms at entry were significantly associated with poorer outcomes across up to 4 treatment levels, as were shorter episodes and some neurovegetative symptoms of depression. However, other indicators of bipolar diathesis including recent maniclike symptoms and family history of bipolar disorder as well as summary measures of bipolar spectrum features were not associated with treatment resistance. CONCLUSION Self-reported psychoticlike symptoms were common in a community sample of outpatients with MDD and strongly associated with poorer outcomes. Overall, the data do not support the hypothesis that unrecognized bipolar spectrum illness contributes substantially to antidepressant treatment resistance.

Abstract
BACKGROUND Previous studies found that patients with depressive disorders frequently have lifetime manic symptoms or even an unrecognized bipolar disorder and that these patients have more severe illness. In this study we investigated whether the presence of significant manic symptoms among patients presenting with depressive and/or anxiety disorders is associated with more severe illness, more comorbidity, more suicidality and more atypical symptoms. METHODS In a large cohort (n=2012) of persons with lifetime depressive and/or anxiety disorders (as confirmed with the Composite International Diagnostic interview (CIDI)) we used the 15-item Mood Disorder Questionnaire (MDQ) to assess the presence of lifetime manic symptoms. Patients with clinically recognized bipolar disorders were excluded from the study. RESULTS Lifetime manic symptoms were present among 6.3% of the persons with depressive or anxiety disorders. Persons with lifetime manic symptoms more frequently had comorbid social phobia, generalized anxiety disorder and alcohol dependence, more frequently reported previous serious suicide attempts and their current depressive symptoms were more severe. Atypical depression symptoms were not more prevalent in persons with lifetime manic symptoms. LIMITATIONS The presence of a lifetime manic or hypomanic episode was not assessed with the CIDI. CONCLUSIONS Identifying lifetime manic symptoms with the MDQ in persons presenting with (unipolar) depressive or anxiety disorders, can not only help the recognition of actual bipolar disorder (as described in previous studies), but also the identification of a subgroup of patients with more severe symptomatology, more comorbid anxiety and alcohol dependence disorders, and more suicidality.

Abstract
OBJECTIVE To review available data pertaining to risk of mania-hypomania among bipolar (BPD) and major depressive disorder (MDD) patients with vs. without exposure to antidepressant drugs (ADs) and consider effects of mood stabilizers. METHOD Computerized searching yielded 73 reports (109 trials, 114 521 adult patients); 35 were suitable for random effects meta-analysis, and multivariate-regression modeling included all available trials to test for effects of trial design, AD type, and mood-stabilizer use. RESULTS The overall risk of mania with/without ADs averaged 12.5%/7.5%. The AD-associated mania was more frequent in BPD than MDD patients, but increased more in MDD cases. Tricyclic antidepressants were riskier than serotonin-reuptake inhibitors (SRIs); data for other types of ADs were inconclusive. Mood stabilizers had minor effects probably confounded by their preferential use in mania-prone patients. CONCLUSION Use of ADs in adults with BPD or MDD was highly prevalent and moderately increased the risk of mania overall, with little protection by mood stabilizers.

Abstract
Patients with hyperthymic and cyclothymic temperaments often develop symptoms that fail to meet diagnostic criteria for bipolar disorders. These patients can be conceived as having bipolar disorder NOS (not otherwise specified), a bipolar spectrum disorder, cyclothymic disorder or cluster B personality traits. Here, we describe four of these patients with mild to moderate symptoms affecting mood, behaviour, emotional reactivity and sleep. Treatment with low-dose quetiapine (25-75 mg/day at night) lead to sustained symptom remission. Two of them were on quetiapine monotherapy. Such low doses occupy a minority of D2 and 5-HT2 receptors, which may nevertheless be of therapeutic value in mild cases. Alternatively, other mechanisms more likely to occur at low doses, such as antagonism of H1, alpha(1B)-adrenergic and other serotonin receptors, as well as reduction cortisol secretion, may be involved in the therapeutic efficacy of quetiapine.

Abstract
BACKGROUND Although (hypo)manic symptoms are common in adolescence, transition to adult bipolar disorder is infrequent. AIMS To examine whether the risk of transition to bipolar disorder is conditional on the extent of persistence of subthreshold affective phenotypes. METHOD In a 10-year prospective community cohort study of 3021 adolescents and young adults, the association between persistence of affective symptoms over 3 years and the 10-year clinical outcomes of incident DSM-IV (hypo)manic episodes and incident use of mental healthcare was assessed. RESULTS Transition to clinical outcome was associated with persistence of symptoms in a dose-dependent manner. Around 30-40% of clinical outcomes could be traced to prior persistence of affective symptoms. CONCLUSIONS In a substantial proportion of individuals, onset of clinical bipolar disorder may be seen as the poor outcome of a developmentally common and usually transitory non-clinical bipolar phenotype.

Abstract
Recent suggestions to extend the boundaries of bipolar disorder to a broader spectrum lead to a concept of bipolarity different from that of classical psychiatry. It has been proposed that many patients with unipolar depression are actually bipolar and that many cases of substance abuse, personality disorders, and childhood behavioral disorders lie within the spectrum. However, since this expanded notion of bipolarity has been defined entirely on the basis of phenomenology, any expansion needs to meet broader criteria for validity. Bipolar spectrum disorders have a different phenomenology, family history, and course than classical bipolar disorders and do not respond in the same way to drugs. Until further research clarifies the boundaries of bipolarity, we should be conservative about extending its scope.

Kelly T, Lieberman DZ. The use of triiodothyronine as an augmentation agent in treatment-resistant bipolar II and bipolar disorder NOS. J Affect Disord 2009; 116:222-6. [PMID: 19215985 DOI: 10.1016/j.jad.2008.12.010] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2008] [Revised: 12/03/2008] [Accepted: 12/09/2008] [Indexed: 10/21/2022]
Abstract
BACKGROUND Thyroid hormone plays a role in both serotonin and catecholamine functions in the brain, and has been linked to abnormal mood states in bipolar disorder. Unlike most studies which have included only patients with bipolar I, this study evaluated triiodothyronine (T3) as an augmentation agent for treatment-resistant depression in patients with bipolar II and bipolar disorder NOS. METHODS This study was a retrospective chart review of patients treated in a private clinic between 2002 and 2006. The charts of 125 patients with bipolar II disorder and 34 patients with bipolar disorder NOS were reviewed. RESULTS Patients had been unsuccessfully treated with an average of 14 other medications before starting T3. At an average dose of 90.4 mcg (range 13 mcg-188 mcg) the medication was well tolerated. None of the patients experienced a switch into hypomania, and only 16 discontinued due to side effects. Improvement was experienced by 84%, and 33% experienced full remission. LIMITATIONS The limitations are those associated with the retrospective chart review design. CONCLUSIONS A high percentage of bipolar II and bipolar NOS patients with treatment resistant depression improved on T3. Despite the use of higher than usual doses in many of the patients, the medication was well tolerated. Augmentation with supraphysiologic doses of T3 should be considered in cases of treatment resistant bipolar depression.
