McElroy SL, Kotwal R, Keck PE, Akiskal HS. Comorbidity of bipolar and eating disorders: distinct or related disorders with shared dysregulations? J Affect Disord 2005; 86:107-27. [PMID: 15935230 DOI: 10.1016/j.jad.2004.11.008] [Citation(s) in RCA: 109] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2004] [Accepted: 11/30/2004] [Indexed: 11/30/2022]
Abstract
BACKGROUND The co-occurrence of bipolar and eating disorders, though of major clinical and public health importance, remains relatively unexamined. METHODS In reviewing the literature on this comorbidity, we compared bulimia, anorexia nervosa, bulimia nervosa, binge eating disorders and bipolar disorders on phenomenology, course, family history, biology, and treatment response. RESULTS Epidemiological studies show an association between subthreshold bipolar disorder and eating disorders in adolescents, and between hypomania and eating disorders, especially binge eating behavior, in adults. Of the clinical studies, most show that patients with bipolar disorder have elevated rates of eating disorders, and vice versa. Finally, the phenomenology, course, comorbidity, family history, and pharmacologic treatment response of these disorders show considerable overlap on all of these parameters. In particular, on phenomenologic grounds--eating dysregulation, mood dysregulation, impulsivity and compulsivity, craving for activity and/or exercise--we find many parallels between bipolar and eating disorders. Overall, the similarities between these disorders were more apparent when examined in their spectrum rather than full-blown expressions. LIMITATIONS Despite an extensive literature on each of these disorders, studies examining their overlap across all these parameters are relatively sparse and insufficiently systematic. CONCLUSIONS Nonetheless, the reviewed literature leaves little doubt that bipolar and eating disorders--particularly bulimia nervosa and bipolar II disorder--are related. Although several antidepressants and mood stabilizers have shown promise for eating disorders, their clinical use when these disorders co-exist with bipolarity is still very much of an art. We trust that this review will stimulate more rigorous research in their shared putative underlying psychobiologic mechanisms which, in turn, could lead to more rational targeted treatments.

Abstract
Bipolar disorder is a chronic, debilitating psychiatric illness with serious ramifications for patients, their families, and society. Despite the availability of effective treatments, this disease often goes untreated due to medical, financial, legal/governmental, and cultural barriers. In this review we explore possible reasons for this problem. Misdiagnosis of bipolar disorders is a common medical barrier. One pathway to care for individuals with bipolar disorder is through referral from primary care, but primary care physicians generally have not received special training in the recognition and management of bipolar disorder. This often leads to diagnostic delays or errors, which prevents timely 'filtering' of patients into specialized care. Using data bases we explored these pathways. Legislation in the USA, such as the Emergency Medical Treatment and Active Labor Act (EMTALA), designed to ensure access to inpatient mental health care, has instead given hospitals financial incentives to limit inpatient mental health care capacities. Reimbursement of mental health care expenses is a significant issue impacting a patient's ability to gain access to care, as bipolar disorder is a costly disease to treat. Improving access to care among the bipolar community will require multilateral strategies to influence the actions and attitudes of patients, communities, providers, health care systems, and state/national governments. In other cultures, barriers to care differ according to a number of factors such as type of services, explanatory models of illness, misdiagnosis and perceptions of care givers. It is essential that clinicians are aware of pathways and barriers so that appropriate and accessible care can be provided.

Abstract
This is a review of the studies comparing unipolar and bipolar depression, with focus on the course, symptomatology, neurobiology, and psychosocial literatures. These are reviewed with one question in mind: does the evidence support diagnosing bipolar and unipolar depressions as the same disorder or different? The current nomenclature of bipolar and unipolar disorders has resulted in research that compares these disorders as a whole, without considering depression separately from mania within bipolar disorder. Future research should investigate two broad categories of depression and mania as separate disease processes that are highly comorbid.

Abstract
BACKGROUND In population surveys, the assessment of mania is commonly done by trained lay interviewers using structured diagnostic instruments: the validity of this approach has been questioned. We examined the criterion validity and prevalence of lifetime mania in a survey of Swedish twins conducted with interview methodology usually applied in psychiatric epidemiology. METHODS 41 838 individuals in the Swedish Twin Registry were evaluated via a telephone interview that included the eight DSM-IV mania items, and these data were merged with inpatient hospitalization discharge diagnoses from two comprehensive national registries (the criterion). An algorithm with eight cut-points was used to diagnose lifetime mania, and compared by a receiver operator characteristic curve to the criterion. The algorithm requiring at least four positive items resembling a DSM-IV diagnosis. RESULTS History of hospitalization for a psychiatric condition that included a manic episode was present for 0.7% of all living twins, and predicted non-response to the survey (OR = 0.5; 95% CI = 0.4-0.6). The incidence rate for first hospitalization was 2.1/10 000 year(-1). For > or =1 symptom (first cut-point), the prevalence, sensitivity and specificity were 3.6%, 39.0% and 96.6%; for > or = 4 symptoms (DSM-IV-like cut-point) 2.6%, 36.5% and 97.6%; and for eight symptoms 0.3%, 18.0% and 99.8%. Positive predictive values were, respectively, 5.5%, 7.0% and 29.8%. CONCLUSIONS The performance of the telephone screening for mania by lay interviewers in terms of positive predictive power was not satisfactory; despite a high specificity, the false positive rate was high. The low population prevalence of mania, non-response bias, criterion choice and inherent limitations of the interviewing method are among the explanations. Assessment of a lifetime manic episode based on lay interviewer screening may yield misleading data.

Abstract
Whether the higher rates of mental hospitalization and involuntary treatment for marginal social groups are due to differential labeling or simply to the occurrence of higher rates of disorder in these groups remains unresolved. I reexamine this issue with data from the National Comorbidity Survey (N = 5,877) that allow comparisons between disturbed individuals living in the community untreated and disturbed persons who have been hospitalized or seen a professional for their mental health problems under pressure or voluntarily. Contrary to labeling theory, members of lower status groups are not consistently overrepresented among those who have been hospitalized or seen a professional against their will. Consistent with self-labeling theory, persons with greater education and those not in poverty are disproportionately present among individuals who sought treatment by choice. Additional analyses show that factors that predict service utilization are important determinants of mental health service use but do not account systematically for status disparities in hospital or outpatient treatment, especially disparities by poverty status. Although I do not confirm a central tenet of labeling theory here, the negative consequences of labeling and stigma continue to be well-supported in the literature.

Abstract
This paper reviews evidence for deficits in goal regulation in bipolar disorder. A series of authors have described mania as related to higher accomplishment, elevated achievement motivation, and ambitious goal setting. These characteristics appear to be evident outside of episodes, and to some extent, among family members of people with a history of mania. In addition, people with a history of mania demonstrate intense mood reactivity, particularly in response to success and reward. During positive moods, they appear to experience robust increases in confidence. These increases in confidence, coupled with a background of ambitious goals, are believed to promote excessive pursuit of goals. This excessive goal engagement is hypothesized to contribute to manic symptoms after an initial life success.

Abstract
BACKGROUND It is well known that affective disorders and migraine often coexist in the same patients, and some information is available indicating that migraine is particularly prevalent in bipolar II disorder. The aims of this study were to compare the clinical features in unipolar depressed patients with and without comorbid migraine to bipolar patients. METHODS Semi-structured interview of 201 patients with major affective disorders, using DSM-IV criteria for affective disorders combined with Akiskal's criteria for affective temperaments, and IHS-criteria for migraine. RESULTS Compared to the group of patients having unipolar depressions without comorbid migraine (n = 51) the group with unipolar depression and migraine (n = 63) had a higher number of depressive episodes (4.5 vs. 2.5, P = 0.017), significantly higher prevalences of affective temperaments (46% vs. 16%, P = 0.001), irritability (70% vs. 45%, P = 0.008), seasonal variation (22% vs. 5%, P = 0.017), agoraphobia (44% vs. 26%, P = 0.036), asthma (25% vs. 6%, P = 0.006) and migraine in family (59% vs. 29%, P = 0.002). The clinical features of unipolar depressed patients with comorbid migraine resemble the bipolar II patients (n = 51) in this sample. LIMITATIONS Non-blind, cross-sectional assessment. CONCLUSIONS These results indicate that there may be important clinical differences between unipolar depressed patients with and without comorbid migraine, possibly indicating that migraine in depressed patients is a bipolar spectrum trait.

Abstract
From diverse perspectives, there is little doubt that depressive symptoms cohere to form a valid and distinct syndrome. Research indicates that an evidence-based assessment of depression would include (a) measures with adequate psychometric properties; (b) adequate coverage of symptoms; (c) adequate coverage of depressed mood, anhedonia, and suicidality; (d) an approach to suicidality that distinguishes between resolved plans and preparations and desire and ideation; (e) assessment of the atypical, seasonal, and melancholic subtypes; (f) parameters of course and chronicity; and (g) comorbidity and bipolarity. These complexities need to be accounted for when certain assessment approaches are preferred, and when ambiguity exists regarding the categorical versus dimensional nature of depression, and whether and when clinician ratings outperform self-report. The authors conclude that no one extant procedure is ideal and suggest that the combination of certain interviews and self-report scales represents the state of the art for evidence-based assessment of depression.

Abstract
OBJECTIVES In this article, we review the evidence for, and implications of, a high rate of comorbid posttraumatic stress disorder (PTSD) in individuals with bipolar disorder. METHODS We reviewed studies providing comorbidity data on patients with bipolar disorder, and also examined the PTSD literature for risk factors and empirically supported treatment options for PTSD. RESULTS Studies of bipolar patients have documented elevated rates of PTSD. Based on our review, representing 1214 bipolar patients, the mean prevalence of PTSD in bipolar patients is 16.0% (95% CI: 14-18%), a rate that is roughly double the lifetime prevalence for PTSD in the general population. Risk factors for PTSD that are also characteristic of bipolar samples include the presence of multiple axis I disorders, greater trauma exposure, elevated neuroticism and lower extraversion, and lower social support and socio-economic status. CONCLUSIONS These findings are discussed in relation to the cost of PTSD symptoms to the course of bipolar disorder. Pharmacological and cognitive-behavioral treatment options are reviewed, with discussion of modifications to current cognitive-behavioral protocols for addressing PTSD in individuals at risk for mood episodes.

Abstract
OBJECTIVES There has been increasing interest in the depressed phase of bipolar disorder (bipolar depression). This paper aims to review the clinical characteristics of bipolar depression, focusing upon its prevalence and phenomenology, related neuropsychological dysfunction, suicidal behaviour, disability and treatment responsiveness. METHODS Studies on the prevalence of depression in bipolar disorder, the comparative phenomenology of bipolar and unipolar depression, as well as neuropsychology and brain imaging studies, are reviewed. To identify relevant papers, a literature search using MEDLINE and PubMed was undertaken. RESULTS Depression is the predominant mood disturbance in bipolar disorder, and most frequently presents as subsyndromal, minor or dysthymic depression. Compared with major depressive disorder (unipolar depression), bipolar depression is more likely to manifest with psychosis, melancholic symptoms, psychomotor retardation (in bipolar I disorder) and 'atypical' symptoms. The few neuropsychological studies undertaken indicate greater impairment in bipolar depression. Suicide rates are high in bipolar disorder, with suicidal ideation, suicide attempts and completed suicides all occurring predominantly in the depressed phase of this condition. Furthermore, the depressed phase (even subsyndromal) appears to be the major contributant to the disability related to this condition. CONCLUSIONS The significance of the depressed phase of bipolar disorder has been markedly underestimated. Bipolar depression accounts for most of the morbidity and mortality due to this illness. Current treatments have significant limitations.

Abstract
OBJECTIVE The Netherlands Mental Health Survey and Incidence Study (NEMESIS) is a Dutch population study using a fully structured interview (Composite International Diagnostic Interview, CIDI), administered by trained interviewers. Based on all three assessments of NEMESIS, 2.4% of the respondents were identified with lifetime bipolar disorder (DSM-III-R). The primary aim of the study was to estimate the prevalence of bipolar disorder in the same population based on a semistructured interview administered by clinicians. METHOD Seventy-four persons identified with a lifetime CIDI/DSM-III-R bipolar disorder and 40 persons with a major depressive disorder (MDD) were reinterviewed with the Structured Clinical Interview for DSM (SCID). RESULTS Based on the SCID, 30 of 74 respondents with a CIDI/DSM-III-R bipolar disorder and eight of 40 respondents with MDD met DSM-IV criteria for bipolar disorder or cyclothymia, corresponding with an adjusted lifetime prevalence in these groups of 1% (95% CI: 0.7-1.3%) and 4.2% (95% CI: 1.6-6.9%) respectively. CONCLUSION Compared with the SCID, the CIDI on the one hand overdiagnoses bipolar disorder but on the other hand underdiagnoses bipolar disorder.

Abstract
OBJECTIVE To report the effect of oxcarbazepine in a patient with bipolar illness and posttraumatic stress disorder (PTSD). CASE SUMMARY A 38-year-old white woman with PTSD and bipolar disorder who had partially responded to carbamazepine was treated with oxcarbazepine. Within a month of initiation of treatment with oxcarbazepine, she reported progressive improvement in her PTSD symptoms. As oxcarbazepine monotherapy with 750 mg twice daily continued, she reported significant reduction of her PTSD symptoms and stabilization of her mood. She tolerated oxcarbazepine without adverse effects. DISCUSSION PTSD symptoms tend to wax and wane. Spontaneous remission also occurs in some patients with PTSD. There are a few reports indicating that carbamazepine alleviates PTSD symptoms. Since oxcarbazepine is an analog of carbamazepine, it is theorized that oxcarbazepine also has efficacy in significantly reducing PTSD symptoms. CONCLUSIONS There are case reports and uncontrolled studies suggesting that antiepileptic drugs (AEDs) alleviate PTSD symptoms. Oxcarbazepine may also benefit patients with PTSD. However, controlled studies are needed to investigate the use of AEDs in patients with PTSD and bipolar disorder.

Abstract
OBJECTIVE To assess the societal costs and quality of life of patients suffering from bipolar disorder in the Netherlands. METHOD Forty persons with a lifetime diagnosis of bipolar disorder (SCID/DSM-IV) and representative for the Dutch general population were interviewed to collect data on direct (use of medical resources) and indirect (productivity losses because of absence from work and reduced efficiency at work) costs of illness. Respondents' quality of life was also assessed. Prevalence (5.2%) of bipolar disorder was used to estimate total costs. RESULTS Total costs of bipolar disorder were estimated at US 1.83 billion dollars (total direct costs = US 454 million dollars; total indirect costs = US 1.37 billion dollars). Participants' quality-of-life scores were lower than those of the general population. CONCLUSION The societal costs form patients suffering of bipolar disorder in the Netherlands were high, especially the indirect costs because of absence from work. The quality of life of bipolar patients was lower than the general population.

Abstract
Transtorno bipolar (TB) é comumente associado à fase final da adolescência ou idade adulta jovem, embora em uma proporção substancial dos pacientes a doença comece em fases mais tardias da vida. Os resultados de várias investigações clínicas sugerem que casos de transtorno bipolar com início tardio têm, mais freqüentemente, uma "causa orgânica" e que isso justificaria a subdivisão do transtorno bipolar entre "início precoce" e "início tardio". Este artigo revê a literatura sobre a hipótese orgânica do transtorno bipolar de início tardio e conclui que essa subdivisão é artificial e carece de suporte clínico e epidemiológico.

Abstract
OBJECTIVES The goal of this article is to provide a comprehensive critical review of studies reporting the prevalence, features, age of onset, course, comorbidity, and neuropsychology of, as well as service utilization, in bipolar disorder in older age. METHODS We searched the Medline, Pubmed, and PsycINFO databases using combinations of the keywords 'Bipolar', 'Manic/a', 'Manic Depression', 'Elderly', and 'Older'. We included English-language reports presenting quantitative data on the prevalence and/or any descriptive information about adults with bipolar disorder over age 50. Findings from similar studies were pooled when possible. A total of 61 studies met our broad criteria. RESULTS Common methodological problems in the published studies included small sample sizes, retrospective chart review, lack of standardized measures, overemphasis on inpatients, and dearth of longitudinal data. Strong evidence indicates that bipolar disorder becomes less common with age, accounts for 8-10% of late life psychiatric admissions, is associated with neurologic factors in late-onset groups, and is a heterogeneous life-long illness. Weak or inconsistent evidence was found for a higher prevalence of mixed episodes in older adults, a lower treatment response, and the association with lower family history in late-onset groups. Minimal information is available on bipolar depression in late life. CONCLUSIONS Bipolar disorder in old age is a growing public health problem. Greater research on bipolar disorder in older people will assist in enhancing services to this group as well as inform research on bipolar disorder across the life span.

Abstract
There have been major advances in clinical understanding and treatment of bipolar disorder over the past decade. Randomised controlled trials of pharmacological treatments and psychological interventions have shown that there are effective short-term and long-term treatments for the disorder. Despite advances in treatment, diagnosis is often delayed or mistaken, and many people who could benefit are not using the treatments available. Functional and symptomatic recovery from episodes of bipolar disorder is frequently less complete than previously considered, and disability is often profound. Although manic episodes are the distinguishing feature of bipolar disorder, it appears that depression is the predominant mood disturbance and that much of the functional impairment associated with bipolar disorder results from this. Comorbidity with anxiety disorders or substance misuse is common. Advances in genetics, brain imaging and basic pharmacology are starting to provide understanding of the complex causative processes.

Abstract
Family, twin, and adoption studies have been essential in defining the genetic epidemiology of bipolar disorder over the past several decades. Family studies have documented that first-degree relatives of affected individuals have an excess risk of the disorder, while twin studies (and to a lesser extent, adoption studies) suggest that genes are largely responsible for this familial aggregation. We review these studies, including the magnitude of familial risk and heritability estimates, efforts to identify familial subtypes of bipolar disorder, and the implications of family/genetic data for validating nosologic boundaries. Taken together, these studies indicate that bipolar disorder is phenotypically and genetically complex.

Abstract
OBJECTIVES Although anxiety disorders often co-occur with bipolar disorder in clinical settings, relatively few studies of bipolar disorder have looked specifically at panic comorbidity. This report examines lifetime panic comorbidity within a sample of families with a history of bipolar disorder. METHODS One hundred and nine probands with bipolar disorder and their 226 siblings were interviewed as part of a family-genetic study. Logistic regression was used to model bipolar disorder as a predictor of comorbid panic in those with affective disorder, with age at interview and gender included as covariates. RESULTS The percentage with panic attacks was low in those without affective disorder (3%) compared with those with unipolar depression (22%) or bipolar disorder (32%). Panic disorder was found only in those with affective disorder (6% for unipolar, 16% for bipolar). When bipolar disorder and unipolar disorder were compared, controlling for age and sex, having bipolar disorder was associated with panic disorder (OR = 3.0, 95% CI = 1.1, 7.8) and any panic symptoms (OR = 2.0, CI = 1.0,3.8) and more weakly with the combination of panic disorder and recurrent attacks (OR = 1.8, CI = 0.9, 3.5). CONCLUSIONS The absence of panic disorder and the low prevalence of any panic symptoms in those without bipolar or unipolar disorder suggest that panic is associated primarily with affective disorder within families with a history of bipolar disorder. Furthermore, panic disorder and symptoms are more common in bipolar disorder than in unipolar disorder in these families.

Abstract
BACKGROUND Psychiatric data on population groups of geographic and social isolates are rare, but can potentially give insights into factors of aetiological importance. The Zeway islanders have lived in geographic and cultural isolation for over three centuries. AIM To determine the prevalence of major psychiatric disorders among the adult population of Zeway islands. METHODS A three stage screening design that included the use of structured interview instruments (CIDI and SCAN), key informants, and clinical assessment by psychiatrists was employed for case identification. RESULTS Prevalence of bipolar disorders among the adult population (n = 1691) was 1.83% (n = 31) with 66% of the cases originating from one of the islands that constitutes only 17.33% of the study population. Only one subject was identified with schizophrenia. CONCLUSIONS A pattern of differential prevalence for bipolar disorders and schizophrenia appears to exist in this isolated population, which also seems shared by other isolated population groups. The high prevalence of bipolar disorders with clustering of cases on one island may represent an environmental or genetic factor of etiologic relevance that deserves further exploration.

Abstract
BACKGROUND The Royal Australian and New Zealand College of Psychiatrists is co-ordinating the development of clinical practice guidelines (CPGs) in psychiatry, funded under the National Mental Health Strategy (Australia) and the New Zealand Health Funding Authority METHOD For these guidelines, the CPG team reviewed the treatment outcome literature (including meta-analyses) and consulted with practitioners and consumers. TREATMENT RECOMMENDATIONS This guideline provides evidence-based recommendations for the management of bipolar disorder by phase of illness, that is acute mania, mixed episodes and bipolar depression, and the prophylaxis of such episodes. It specifies the roles of various mood-stabilizing medications and of psychological treatments such as cognitive therapy and psycho-education.

Abstract
Most health and work productivity studies have focused on individual conditions without considering comorbidity. We illustrate the implication of this neglect by examining the effects of comorbid mental disorders on role impairment (number of sickness absence and work cut-back days in the past month) among people with chronic physical disorders. A nationally representative household survey of 5877 respondents assessed current mental and physical disorders and role impairments. Four physical disorders were sufficiently common to be studied: hypertension, arthritis, asthma, and ulcers. All 4 physical disorders were associated with significant role impairments in bivariate analyses. However, further analysis showed that these impairments were almost entirely confined to cases with comorbid mental disorders. Effectiveness trials in workplace samples are needed to evaluate the cost-effectiveness of treating comorbid mental disorders among workers with chronic physical disorders.

Abstract
OBJECTIVE To examine nationally representative patterns and predictors of delays in contacting a professional after first onset of a mental disorder. DATA SOURCES The National Comorbidity Survey, a nationally representative survey of 8,098 respondents aged 15-54. STUDY DESIGN Cross-sectional survey. DATA COLLECTION Assessed lifetime DSM-III-R mental disorders using a modified version of the Composite International Diagnostic Interview (CIDI). Obtained reports on age at onset of disorders and age of first treatment contact with each of six types of professionals (general medical doctors, psychiatrists, other mental health specialists, religious professionals, human services professionals, and alternative treatment professionals). Used Kaplan-Meier (KM) curves to estimate cumulative lifetime probabilities of treatment contact after first onset of a mental disorder. Used survival analysis to study the predictors of delays in making treatment contact. PRINCIPAL FINDINGS The vast majority (80.1 percent) of people with a lifetime DSM-III-R disorder eventually make treatment contact, although delays average more than a decade. The duration of delay is related to less serious disorders, younger age at onset, and older age at interview. There is no evidence that delay in initial contact with a health care professional is increased by earlier contact with other non-health-care professionals. CONCLUSIONS Within the limits of recalling lifetime events, it appears that delays in initial treatment contact are an important component of the larger problem of unmet need for mental health care. Interventions are needed to decrease these delays.

Abstract
OBJECTIVE To study rates and ages of onset of DSM-IV syndromal and subsyndromal comorbidity in a prepubertal and early adolescent bipolar disorder phenotype (PEA-BP) (N = 93) compared to attention-deficit/hyperactivity disorder (ADHD) (N = 81). METHOD The WASH-U-KSADS was given by raters blinded to subject group separately to mothers about their children and to children about themselves. PEA-BP was defined as DSM-IV mania with at least one cardinal symptom of mania (elation or grandiosity) to avoid diagnosing using only symptoms that overlapped with those for ADHD. Syndromal diagnoses required a CGAS score of 60 or less to ensure severity at a level of definite "caseness." RESULTS PEA-BP subjects were aged 10.9 (SD = 2.6) at baseline and 6.8 (SD = 3.4) at onset of first mania episode. Rates of oppositional defiant disorder and total number of comorbidities were significantly higher in the PEA-BP group than the ADHD group. In PEA-BP subjects, mean ages of onset of ADHD occurred before the first manic episode, and obsessive compulsive, oppositional defiant, social phobia, generalized anxiety, separation anxiety, and conduct disorders occurred after. CONCLUSIONS Onsets of ADHD before mania and of oppositional defiant disorder/conduct disorder after mania have clinical and research implications. These include the need to examine for mania symptoms in children with ADHD and/or oppositional defiant disorder/conduct disorder and to develop scales to differentiate preschool mania from ADHD. Comparison with other studies demonstrated the importance of DSM system and severity scales in reporting comorbidity rates.

Abstract
Chronic pain and psychiatric disorders frequently co-occur. However, estimates of the magnitude of these associations have been biased by the use of select clinical samples. The present study utilized the National Comorbidity Survey [Arch. Gen. Psychiatry 51 (1994) 8-19] Part II data set to investigate the associations between a chronic pain condition (i.e. arthritis) and common mood and anxiety disorders in a sample representative of the general US civilian population. Participants (N=5877) completed the Composite International Diagnostic Interview [World Health Organization (1990)], a structured interview for trained non-clinician interviewers based on the revised third edition of the Diagnostic and Statistical Manual of Mental Disorders [American Psychiatric Association (1987)], and provided self-reports of pain and disability associated with a variety of medical conditions. Significant positive associations were found between chronic pain and individual 12-month mood and anxiety disorders [odds ratios (OR) ranged from 1.92 to 4.27]. The strongest associations were observed with panic disorder (OR=4.27) and post-traumatic stress disorder (OR=3.69). The presence of one psychiatric disorder was not significantly associated with pain-related disability, but the presence of multiple psychiatric disorders was significantly associated with increased disability. The findings of the present study raise the possibility that improved efforts regarding the detection and treatment of anxiety disorders may be required in pain treatment settings.

Abstract
OBJECTIVE Recent reports raise concern that children with attention deficit hyperactivity disorder (ADHD) and some manic symptoms may worsen with stimulant treatment. This study examines the response to methylphenidate in such children. METHODS Data from children participating in the 1-month methylphenidate titration trial of the Multimodal Treatment Study of Children with ADHD were reanalyzed by dividing the sample into children with and without some manic symptoms. Two "mania proxies" were constructed using items from the Diagnostic Interview Schedule for Children (DISC) or the Child Behavior Checklist (CBCL). Treatment response and side effects are compared between participants with and without proxies. RESULTS Thirty-two (11%) and 29 (10%) participants fulfilled criteria for the CBCL mania proxy and DISC mania proxy, respectively. Presence or absence of either proxy did not predict a greater or lesser response or side effects. CONCLUSION Findings suggest that children with ADHD and manic symptoms respond robustly to methylphenidate during the first month of treatment and that these children are not more likely to have an adverse response to methylphenidate. Further research is needed to explore how such children will respond during long-term treatment. Clinicians should not a priori avoid stimulants in children with ADHD and some manic symptoms.

Abstract
OBJECTIVE Phenomenology, assessment, longitudinal, and psychosocial findings from an ongoing, controlled, prospective study of 93 subjects with a prepubertal and early adolescent bipolar disorder phenotype (PEA-BP) will be reviewed. METHODS Unlike adult-onset bipolar disorder, for which there were over 50 years of systematic investigations, there were a paucity of rigorous data and much controversy and skepticism about the existence and characteristics of prepubertal-onset mania. With this background, issues to address for investigation of child-onset mania included the following: (i) What to do about the differentiation of mania from attention-deficit hyperactivity disorder (ADHD). (ii) How to deal with the ubiquity of irritability as a presenting symptom in multiple child psychiatry disorders. (iii) Development of a research instrument to assess prepubertal manifestations of adult mania (i.e. children do not 'max out' credit cards or have four marriages). (iv) How to distinguish normal childhood happiness and expansiveness from pathologically impairing elated mood and grandiosity. RESULTS To address these issues, a PEA-BP phenotype was defined as DSM-IV mania with elated mood and/or grandiosity as one inclusion criterion. This criterion ensured that the diagnosis of mania was not made using only criteria that overlapped with those for ADHD, and that subjects had at least one of the two cardinal symptoms of mania (i.e. elated mood and grandiose behaviors). Subjects were aged 10.9 years (SD = 2.6) and age of onset of the current episode at baseline was 7.3 years (SD = 3.5). Validation of PEA-BP was shown by reliable assessment, 6-month stability, and 1- and 2-year diagnostic longitudinal outcome. PEA-BP resembled the severest form of adult-onset mania by presenting with a chronic, mixed mania, psychotic, continuously (ultradian) cycling picture. CONCLUSION Counterintuitively, typical 7-year-old children with PEA-BP were more severely ill than typical 27 year olds with adult-onset mania. Moreover, longitudinal data strongly supported differentiation of PEA-BP from ADHD.

Abstract
OBJECTIVES GAMIAN-Europe is a pan-European federation of national patient organizations from 30 European countries covering the whole spectrum of psychiatry. To gain a better understanding of what it is like to live with bipolar disorder (BD), GAMIAN-Europe undertook a detailed patient-based questionnaire, known as 'GAMIAN-Europe/BEAM Survey', examining a variety of aspects. METHODS The questionnaire was mailed to 3450 patients from 12 member organizations in 11 countries. A total of 1760 completed questionnaires were received but 28 were ruled out as inappropriate. Of the remainder, 1041 respondents stated that they had been, or were, suffering from BD. The remainder stated that they were suffering from depression, dysthymia or atypical depression. RESULTS The findings indicate that, on average, a bipolar patient is expected to wait for 5.7 years for a correct diagnosis from the first onset of symptoms. Many patients have a family history of mood and anxiety disorders. They experience a high degree of stigmatization from all quarters. This is reflected in the difficulties they experience in obtaining employment despite high academic achievement. Most patients receive combination therapy. Compliance problems resulting from adverse side-effects are less significant than in the past. Overall, the level of satisfaction with pharmacotherapy was high yet, paradoxically, patients had reservations about dependency issues and possible long-term side-effects. CONCLUSIONS There was a clear need for more patient education about pharmacological and psychosocial interventions, despite material progress having been made over the past decade. There is an urgent need for more information and education for both relatives and the public in most European countries to improve awareness and understanding of BDs and other mood disorders and the doctor-patient dialogue.

Abstract
OBJECTIVE There is a consensus that genetic factors are important in the causation of bipolar disorder (BPD); however, little is known about other risk factors in the aetiology of BPD. Our aim was to review the literature on such risk factors - risk factors other than family history of affective disorders - as predictors for the initial onset of BPD. METHODS We conducted a literature search using the MEDLINE, PsycINFO and EMBASE databases. We selected factors of interest including demographic factors, factors related to birth, personal, social and family backgrounds, and history of medical conditions. The relevant studies were extracted systematically according to a search protocol. RESULTS We identified approximately 100 studies that addressed the associations between antecedent environmental factors and a later risk for BPD. Suggestive findings have been provided regarding pregnancy and obstetric complications, winter-spring birth, stressful life events, traumatic brain injuries and multiple sclerosis. However, evidence is still inconclusive. Childbirth is likely to be a risk factor. The inconsistency across studies and methodological issues inherent in the study designs are also discussed. CONCLUSION Owing to a paucity of studies and methodological issues, risk factors of BPD other than family history of affective disorders have generally been neither confirmed nor excluded. We call for further research.

Abstract
INTRODUCTION The Hypomanic Personality Scale (Hyp; Eckblad and Chapman, 1986) might be an indicator for the risk for bipolar affective disorders. We investigated whether the results with American samples can be replicated in a different sample. METHODS The participants (N=224) completed a questionnaire package including the Hyp Scale and were independently interviewed with a psychiatric interview schedule. RESULTS Compared to the control group, persons scoring high on the Hyp scale reported significantly more manic or hypomanic episodes but not episodes of major depression. Correspondingly, the risk group exceeded the control group only on the rate of bipolar affective disorders (20.8% vs. 1.3%) but not unipolar depression, anxiety disorders, or other psychiatric conditions. CONCLUSIONS It seems that the Hyp scale assesses a similar concept in American and German samples, and that it might be a useful tool to study more closely the processes associated with the development of bipolar spectrum disorders.

Abstract
The British Association for Psychopharmacology guidelines specify the scope and target of treatment for bipolar disorder. They are based explicitly on the available evidence and presented, similar to previous Clinical Practice guidelines, as recommendations to aid clinical decision-making for practitioners. They may also serve as a source of information for patients and carers. The recommendations are presented together with a more detailed review of the available evidence. A consensus meeting, involving experts in bipolar disorder and its treatment, reviewed key areas and considered the strength of evidence and clinical implications. The guidelines were drawn up after extensive feedback from participants and interested parties. The strength of supporting evidence was rated. The guidelines cover the diagnosis of bipolar disorder, clinical management and strategies for the use of medicines in short-term treatment of episodes, relapse prevention and stopping treatment.

Abstract
Bipolar disorder is a complex, chronic condition associated with considerable morbidity and mortality, including a high rate of suicide. Currently available treatment options for bipolar disorder fail to adequately address many of the important needs of bipolar patients. Long-term maintenance therapy with lithium has been shown to prevent further episodes of mania and depression and to decrease the likelihood of suicide. However, many patients stop lithium treatment after only a few weeks, because of either untoward side effects or other factors, such as the belief that they no longer require medication. Even when lithium is taken regularly and at adequate doses, many patients continue to exhibit severe functional disability and also fail to achieve remission. Bipolar depression is also poorly understood and difficult to treat. A number of adjunctive medications are used in combination with lithium, but residual symptoms and recurring episodes of mania and depression remain common. Recently, atypical antipsychotics, such as olanzapine, risperidone, and quetiapine, have been evaluated for the treatment of bipolar disorder. Although considerable research is still needed, preliminary findings suggest that some of these agents may act as mood stabilizers, improving the acute symptoms of mania without inducing depression or rapid cycling. The role of atypical antipsychotics in maintenance therapy for bipolar disorder is currently being evaluated in a number of large clinical trials.

Abstract
BACKGROUND The present study examined whether specific types of comorbid anxiety disorders, namely panic disorder (PD), social phobia (SP) and obsessive-compulsive disorder (OCD) are differentially associated with course variables and insight into bipolar illness. METHOD The sample consisted of 151 consecutively hospitalized patients with bipolar I disorder. They were assessed in the week prior to discharge using the Structured Clinical Interview for DSM-III-R (SCID-P), the Brief Psychiatric Rating Scale (BPRS), the Global Assessment of Functioning Scale (GAF) and the Hopkins Symptom Checklist (HSCL-90). Level of insight was assessed with the Scale to assess Unawareness of Mental Disorders (SUMD). RESULTS Of the 151 bipolar subjects, 92 had no PD, SP and OCD comorbidity, 35 had PD and 24 had SP and/or OCD. The three groups differed significantly on the current awareness of illness and treatment response scores and the retrospective awareness of illness and treatment response scores. Post-hoc analyses revealed that, compared with bipolar patients without PD/SD/OCD and those with comorbid PD, patients with comorbid SP and/or OCD had better insight on current awareness of illness, current awareness of treatment response, retrospective awareness of illness and retrospective awareness of treatment response. The regression analysis showed that the presence of no panic type anxiety comorbidity was a predictor of good insight. CONCLUSIONS These data indicate the value of identifying comorbid anxiety disorders in patients with bipolar illness. The results could be interpreted as evidence of discrete disorders within the bipolar spectrum, one that is characterized by, among other things, SP and/or OCD with good insight, another characterized by PD with poor insight.

Abstract
The frequent comorbidity of anxiety disorders and mood disorders has been documented in previous studies. However, it remains unclear whether specific anxiety traits or disorders are more closely associated with unipolar major depression (MDD) or bipolar disorder (BPD). We sought to examine whether MDD and BPD can be distinguished by their association with specific types of anxiety comorbidity. Individuals with a primary lifetime diagnosis of either bipolar disorder (N=122) or major depressive disorder (N=114) received diagnostic assessments of anxiety disorder comorbidity, and completed questionnaires assessing anxiety sensitivity and neuroticism. The differential association of these anxiety phenotypes with MDD versus BPD was examined with multivariate modeling. Panic disorder and generalized anxiety disorder (GAD) specifically emerged amongst all the anxiety disorders as significantly more common in patients with BPD than MDD. After controlling for current mood state, anxiety sensitivity and neuroticism did not differ by mood disorder type. This study supports prior research suggesting a specific panic disorder-bipolar disorder connection, and suggests GAD may also be differentially associated with BPD. Further research is needed to clarify the etiologic basis of anxiety disorder/BPD comorbidity and to optimize treatment strategies for patients with these co-occurring disorders.

Abstract
Generalized anxiety disorder (GAD) is a prevalent and disabling disorder characterized by persistent worrying, anxiety symptoms, and tension. It is the most frequent anxiety disorder in primary care, being present in 22% of primary care patients who complain of anxiety problems. The high prevalence rate of GAD in primary care (8%) compared to that reported in the general population (12-month prevalence 1.9-5.1%) suggests that GAD patients are high users of primary care resources. GAD affects women more frequently than men and prevalence rates are high in midlife (prevalence in females over age 35: 10%) and older subjects but relatively low in adolescents. The natural course of GAD can be characterized as chronic with few complete remissions, a waxing and waning course of GAD symptoms, and the occurrence of substantial comorbidity particularly with depression. Patients with GAD demonstrate a considerable degree of impairment and disability, even in its pure form, uncomplicated by depression or other mental disorders. The degree of impairment is similar to that of cases with major depression. GAD comorbid with depression usually reveals considerably higher numbers of disability days in the past month than either condition in its pure form. As a result, GAD is associated with a significant economic burden owing to decreased work productivity and increased use of health care services, particularly primary health care. The appropriate use of psychological treatments and antidepressants may improve both anxiety and depression symptoms and may also play a role in preventing comorbid major depression in GAD thus reducing the burden on both the individual and society.

Abstract
OBJECTIVE To document the effectiveness and vicissitudes of treating 14 bipolar patients with lithium carbonate over a combined 300 years, and an average of 21 years/patient. METHODS Chart review of the narrative and laboratory studies of these 14 patients ranging in duration from 12 to 29 years. RESULTS Lithium stabilized these bipolar patients over these periods. Only three patients required hospitalization, one because lithium was slowly tapered at her request after 6 years of mood stability, another because of non-compliance, and a third because of co-morbid alcohol abuse. One patient attempted suicide after lithium was tapered off. However, in some patients, there were serious side-effects necessitating lithium discontinuation. CONCLUSIONS Controlled studies in psychopharmacology are obviously preferred to open-label or naturalistic case studies. However, controlled studies are rarely conducted over long periods, and practice-related naturalistic research can be of value, albeit anecdotal and without the use of structured rating scales. In this paper, we are reporting on 14 patients seen consistently by one psychiatrist. These patients were functional and productive at work and in family life. The patients suffered brief hypomanic or depressive episodes. Although several patients experienced serious side-effects, lithium was continued with stable mood, while the side-effects were managed in collaboration with other specialists.

Abstract
Bipolar disorder is a chronic affective disorder that causes significant economic burden to patients, families and society. It has a lifetime prevalence of approximately 1.3%. Bipolar disorder is characterised by recurrent mania or hypomania and depressive episodes that cause impairments in functioning and health-related quality of life. Patients require acute and maintenance therapy delivered via inpatient and outpatient treatment. Patients with bipolar disorder often have contact with the social welfare and legal systems; bipolar disorder impairs occupational functioning and may lead to premature mortality through suicide. This review examines the symptomatology of bipolar disorder and identifies those features that make it difficult and costly to treat. Methods for assessing direct and indirect costs are reviewed. We report on comprehensive cost studies as well as administrative claims data and program evaluations. The majority of data is drawn from studies conducted in the US; however, we discuss European studies when appropriate. Only two comprehensive cost-of-illness studies on bipolar disorder, one prevalence-based and one incidence-based, have been reported. There are, however, several comprehensive cost-of-illness studies measuring economic burden of affective disorders including bipolar disorder. Estimates of total costs of affective disorders in the US range from $US30.4-43.7 billion (1990 values). In the prevalence-based cost-of-illness study on bipolar disorder, total annual costs were estimated at $US45.2 billion (1991 values). In the incidence-based study, lifetime costs were estimated at $US24 billion. Although there have been recent advances in pharmacotherapy and outpatient therapy, hospitalisation still accounts for a substantial portion of the direct costs. A variety of outpatient services are increasingly important for the care of patients with bipolar disorder and costs in this area continue to grow. Indirect costs due to morbidity and premature mortality comprise a large portion of the cost of illness. Lost workdays or inability to work due to the disease cause high morbidity costs. Intangible costs such as family burden and impaired health-related quality of life are common, although it has proved difficult to attach monetary values to these costs.

Abstract
Two National Institute of Mental Health-sponsored meetings of experts on bipolar illness (in 1989 and 1994) noted a paucity of clinical psychopharmacological trials in this illness which has now extended over the past two decades. One of the reasons elucidated for this neglect was a lack of agreement in the field as to what constituted an optimal clinical trial design, consequently resulting in low-priority scores for funding of studies in bipolar illness. In this paper, we note some of the characteristics of bipolar illness that make it particularly difficult to study and find such agreed upon trial designs. Some of the assets and liabilities of the well-accepted traditional parallel group, placebo-controlled, randomized clinical trial (RCT) are reviewed, and a series of other potential design options, such as crossover, enrichment, off-on-off-on (B-A-B-A), and N-of-1 trials, are discussed that may help to better address some of the unique clinical characteristics of bipolar illness. Finally, a variety of statistical approaches to analyzing data in off-on-off-on trial designs, and in helping to predetermine necessary durations of clinical trials in individual patients with bipolar disorders, are suggested. Acceptance of a wider variety of clinical trial designs may help facilitate the funding and accelerate the acquisition of new data on treatment of bipolar illness.

Abstract
BACKGROUND Bipolar disorder is a chronic illness that may involve multiple relapses and result in substantial psychosocial impairment. However, very few recent studies have investigated the economic burden of the disease. OBJECTIVE To assess the frequency of hospitalisation and the inpatient care costs associated with manic episodes in patients with bipolar I disorder in France. METHOD A cost-of-illness study was conducted based on available data using a hospital payer perspective. The lifetime prevalence of manic episodes was estimated from published epidemiological data using a random-effects meta-analysis. Data were obtained by a computerised literature search using the main scientific and medical databases. Additional epidemiological references were identified from published studies and textbooks. Data on frequency of hospitalisation and length of stay were collected from a large psychiatric university hospital. Data on unit costs for inpatient care were obtained from the accounting system of the largest hospital group in Paris, France for the year 1999. RESULTS Extrapolating from international data on the average prevalence of bipolar I disorder, the proportion of rapid cycling patients and the average cycle duration, we estimated the annual number of manic episodes in patients with bipolar I disorder to be around 265,000 in France. Based on hospital data in Paris, the proportion of manic episodes that require hospitalisation was estimated to be around 63%. The average length of stay was 32.4 days and the hospitalisation-related costs were estimated to be around 8.8 billion French francs (Euro 3 billion) [1999 values]. CONCLUSION Our study highlights the lack of medical and economic data on the frequency and hospitalisation-related costs of manic episodes in patients with bipolar I disorder in France. As the lifetime prevalence of bipolar I disorder may be as high as 3% among adults, further studies are required in order to provide representative national data and to allow economic evaluations of costs related to bipolar I disorder in France.

Abstract
Despite advances in the pharmacologic treatment of bipolar disorder, it is clear that additional strategies are needed to provide patients with longer-term mood stability. Recent years have witnessed the development of a number of psychosocial strategies for bipolar disorder that are design as adjuncts to ongoing pharmacotherapy. In this article we describe psychoeducational and cognitive-behavioral approaches to the management of bipolar disorder, with emphasis on broader treatment packages that can be offered by cognitive-behavior therapists working in specialty bipolar clinics, as well as specific strategies that can be integrated into standard pharmacotherapy for the disorder. A growing body of evidence documents the potential value of these interventions, and large-scale studies are underway, including the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), which will provide outcome on these interventions from the perspective of large, multicenter trials.

Abstract
Before adolescence, the rates of depression are similar in girls and boys (or are slightly higher in boys). Yet with the onset of puberty, the gender proportion of depression dramatically shifts to a two girls to one boy ratio. What, then, is the relationship between menarche and the onset of major depression in early adolescence? Recent literature intimates that vulnerability to depression may be rooted in an intricate meld of genetic traits, normal female hormonal maturational processes, and gender socialization. Information regarding gender differences in the presentation of depressive symptoms is provided along with biologic, psychologic, and sociologic factors contributing to depression in adolescent girls. The burden of illness associated with onset of depression after menarche reinforces the importance of prevention or else expeditious recognition and intervention.

Abstract
To expand and accelerate research on mood disorders, the National Institute of Mental Health (NIMH) developed a project to formulate a strategic research plan for mood disorder research. One of the areas selected for review concerns the development and natural history of these disorders. The NIMH convened a multidisciplinary Workgroup of scientists to review the field and the NIMH portfolio and to generate specific recommendations. To encourage a balanced and creative set of proposals, experts were included within and outside this area of research, as well as public stakeholders. The Workgroup identified the need for expanded knowledge of mood disorders in children and adolescents, noting important gaps in understanding the onset, course, and recurrence of early-onset unipolar and bipolar disorder. Recommendations included the need for a multidisciplinary research initiative on the pathogenesis of unipolar depression encompassing genetic and environmental risk and protective factors. Specifically, we encourage the NIMH to convene a panel of experts and advocates to review the findings concerning children at high risk for unipolar depression. Joint analyses of existing data sets should examine specific risk factors to refine models of pathogenesis in preparation for the next era of multidisciplinary research. Other priority areas include the need to assess the long-term impact of successful treatment of juvenile depression and known precursors of depression, in particular, childhood anxiety disorders. Expanded knowledge of pediatric-onset bipolar disorder was identified as a particularly pressing issue because of the severity of the disorder, the controversies surrounding its diagnosis and treatment, and the possibility that widespread use of psychotropic medications in vulnerable children may precipitate the condition. The Workgroup recommends that the NIMH establish a collaborative multisite multidisciplinary Network of Research Programs on Pediatric-Onset Bipolar Disorder to achieve a better understanding of its causes, course, treatment, and prevention. The NIMH should develop a capacity-building plan to ensure the availability of trained investigators in the child and adolescent field. Mood disorders are among the most prevalent, recurrent, and disabling of all illnesses. They are often disorders of early onset. Although the NIMH has made important strides in mood disorders research, more data, beginning with at-risk infants, children, and adolescents, are needed concerning the etiology and developmental course of these disorders. A diverse program of multidisciplinary research is recommended to reduce the burden on children and families affected with these conditions.

Abstract
The aim of this study was to assess the comorbidity of lifetime and current prevalences of anxiety disorders among 70 patients with bipolar I disorder in remission using structured diagnostic interviews and to examine the association between comorbidity and several demographic and clinical variables. Forty-three (61.4%) bipolar I patients also met DSM-IV criteria for at least one lifetime comorbid anxiety disorder. Obsessive-compulsive disorder (39%) was the most common comorbid lifetime anxiety disorder, followed by simple phobia (26%) and social phobia (20%). First episode and male sex were found to have lower rates of comorbid current anxiety disorders. The presence of anxiety disorders was related to significantly higher scores on both anxiety and general psychopathology scales. The results of the present study support previous findings of a high comorbidity rate of anxiety disorders in bipolar I disorder cases and indicate that the presence of an anxiety disorder leads to more severe psychopathology levels in bipolar I patients.

Abstract
BACKGROUND Little is known about the prevalence of bipolar disorder in the general population, what proportion is receiving care and what factors motivate people to seek help. METHOD Data were derived from The Netherlands Mental Health Survey and Incidence Study (NEMESIS), a psychiatric epidemiological study in the general population in The Netherlands. DSM-III-R diagnoses were based on the Composite International Diagnostic Interview (CIDI). RESULTS Lifetime prevalence of bipolar disorder was 1.9%. Compared to other mental disorders, people with bipolar disorder were more often incapacitated were more likely to have attempted suicide and reported a poorer quality of life 82.8% had experienced an additional mental disorder in their lifetime; 25.5% had never sought help for their emotional problems, not even primary, informal or alternative care. LIMITATIONS Three limitations of the study are: (1) the CIDI prevalence estimates for bipolar disorder may be inflated; (2) personality disorders were not recorded in the NEMESIS dataset; (3) in NEMESIS certain groups have not been reached. CONCLUSION Three-quarters of the bipolar respondents do not benefit sufficiently from the treatment methods now available. In view of the serious consequences of this condition, greater efforts are needed to reach people with bipolar disorder, to get them into treatment.

Abstract
Gender differences in the social anxiety spectrum and their correlation with other psychopathological features were analyzed in 520 students by using two questionnaires: the Social Anxiety Spectrum Self-Report (SHY-SR), which explores social anxiety spectrum, and the General Spectrum Measure (GSM), which explores panic-agoraphobia, mood, obsessive-compulsive, and eating-behavior features. Mean SHY-SR total score was significantly higher in women than in men, and gender differences were particularly pronounced for interpersonal sensitivity domain. Likewise, GSM scores were higher in women, except for the manic section. The SHY-SR domains correlated significantly with all GSM sections, except for the manic section. In conclusion, women reported more symptoms than men (who belonged to different psychopathologic dimensions) and displayed a profile of social anxiety spectrum that differs quantitatively but not qualitatively from the men's profile. The correlation between social anxiety spectrum and other psychopathological features mirrors previous findings concerning the high comorbidity of axis-I social anxiety disorder.

Abstract
BACKGROUND Although symptoms of anxiety as well as anxiety disorders commonly occur in patients with bipolar disorder, the pathophysiologic, theoretical, and clinical significance of their co-occurrence has not been well studied. METHODS The epidemiological and clinical studies that have assessed the overlap of bipolar and anxiety disorders are reviewed, with focus on panic disorder and obsessive-compulsive disorder (OCD), and to a lesser extent, social phobia and post-traumatic stress disorder. Potential neural mechanism and treatment response data are also reviewed. RESULTS A growing number of epidemiological studies have found that bipolar disorder significantly co-occurs with anxiety disorders at rates that are higher than those in the general population. Clinical studies have also demonstrated high comorbidity between bipolar disorder and panic disorder, OCD, social phobia, and post-traumatic stress disorder. Psychobiological mechanisms that may account for these high comorbidity rates likely involve a complicated interplay among various neurotransmitter systems, particularly norepinephrine, dopamine, gamma-aminobutyric acid (GABA), and serotonin. The second-messenger system constituent, inositol, may also be involved. Little controlled data are available regarding the treatment of bipolar disorder complicated by an anxiety disorder. However, adequate mood stabilization should be achieved before antidepressants are used to treat residual anxiety symptoms so as to minimize antidepressant-induced mania or cycling. Moreover, preliminary data suggesting that certain antimanic agents may have anxiolytic properties (e.g. valproate and possibly antipsychotics), and that some anxiolytics may not induce mania (e.g. gabapentin and benzodiazepines other than alprazolam) indicate that these agents may be particularly useful for anxious bipolar patients. CONCLUSIONS Comorbid anxiety symptoms and disorders must be considered when diagnosing and treating patients with bipolar disorder. Conversely, patients presenting with anxiety disorders must be assessed for comorbid mood disorders, including bipolar disorder. Pathophysiological, theoretical, and clinical implications of the overlap of bipolar and anxiety disorders are discussed.
