The relationship between attention deficit hyperactivity disorder, bipolarity and mixed features in major depressive patients: Evidence from the BRIDGE-II-Mix Study. J Affect Disord 2019; 246:346-354. [PMID: 30597295 DOI: 10.1016/j.jad.2018.12.089] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 11/25/2018] [Accepted: 12/24/2018] [Indexed: 02/07/2023]
Abstract
OBJECTIVE This study primarily focused on the relationship between comorbid attention deficit-hyperactivity disorder (ADHD), mixed features and bipolarity in major depressive patients. METHODS The sample comprised 2777 patients with Major Depressive Episode (MDE) enrolled in a multicentre, multinational study originally designed to assess different definitions of mixed depression. Socio-demographic, familial and clinical characteristics were compared in patients with (ADHD + ) and without (ADHD-) comorbid ADHD. RESULTS Sixty-one patients (2.2%) met criteria for ADHD. ADHD was associated with a higher number of (hypo)manic symptoms during depression. Mixed depression was more represented in ADHD + patients than in ADHD- using both DSM-5 and experimental criteria. Differences were maintained after removing overlapping symptoms between (hypo)mania and ADHD. ADHD in MDE was also associated with a variety of clinical and course features such as onset before the age of 20, first-degree family history of (hypo)mania, past history of antidepressant-induced (hypo)manic switches, higher number of depressive and affective episodes, atypical depressive features, higher rates of bipolarity specifier, psychiatric comorbidities with eating, anxiety and borderline personality disorders. LIMITATIONS The study was primarily designed to address mixed features in ADHD, with slightly reduced sensitivity to the diagnosis of ADHD. Other possible diagnostic biases due to heterogeneity of participating clinicians. CONCLUSIONS In a sample of major depressive patients, the comorbid diagnosis of current ADHD is associated with bipolar diathesis, mixed features, multiple psychiatric comorbidity and a more unstable course. Further prospective studies are necessary to confirm the possible mediating role of temperamental mood instability and emotional dysregulation in such a complex clinical presentation.

Differential clinical characteristics and possible predictors of bipolarity in a sample of unipolar and bipolar inpatients. Psychiatry Res 2018; 270:1099-1104.

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

Abstract
INTRODUCTION Decreased libido is recognized as one of the vegetative symptoms of depression. Increased libido has not been acknowledged as one of its symptoms, neither has it been reported, particularly in depressed bipolar patients. AIM We hereby report a case of atypical presentation of increased sexual function in a patient in depressed phase of bipolar II thereby querying the fact, whether increased libido is actually an unrecognized atypical symptom of bipolar depression. METHODS A 48-year-old male presented with mood swings whereby his sexual function was increased during his depressive phase. Antidepressant, mood stabilizer, and antipsychotic medication were administered. Electroconvulsive therapy (ECT) was offered for augmentation therapy. MAIN OUTCOME MEASURES When sexual dysfunction is not identified, there is a risk of misdiagnosis and mismanagement. RESULTS Patient did not attain full remission with medication. Compliance with medication was an issue, most probably due to the sexual side effects. The patient refused ECT. CONCLUSION This case highlights atypical presentation of high libido in a patient in the depressive phase of bipolar II disorder. The uncommon presentation of a common illness posed a diagnostic challenge and complicated the subsequent management. It was concluded that increased sexual function deserves further consideration as a symptom of bipolar depression.

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
Depersonalization represents an unspecific symptom which is to be found across the entire spectrum of psychiatric nosology. Delineating the historical lines of development of the depersonalization concept and reviewing existing psychopathological experiential knowledge reveals that depersonalization is underpinned by highly diverse modes of experience. In terms of differential diagnostics at the symptom level, a distinction can be made between depersonalization as a neurotic phenomenon on the one hand and a psychotic form occurring in schizophrenia and melancholia on the other. The reference points defined here extend beyond current descriptive classifications and open up the diagnostic process to allow an inclusion of etiological and therapeutic aspects.

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 Classical authors had hypothesized that affective temperaments represent the subclinical manifestations of mood disorders: in particular, cyclothymic and hyperthymic temperaments have been considered as a subthreshold variant of bipolar disorder. The aim of our study is to test the presence of affective temperaments in a group of Italian patients with major depressive disorder (MDD), and to test the association between cyclothymic temperament and well-established validators of bipolar disorder diagnosis such as age at onset and family history of bipolar disorder. METHODS Patients with diagnosis of major depressive disorder (DSM-IV-TR) were included in the study. Affective temperaments have been evaluated through the Italian semistructured interview version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego (TEMPS-I). In order to improve the accuracy of family history and age at onset reports, close family members of the patients were also interviewed. RESULTS 104 of patients included in the study have completed the temperament interview. 25.5% were diagnosed with a dominant affective temperament. Cyclothymic affective temperament was the most represented in the sample of MDD patients (12.3%); depressive, hyperthymic and irritable temperaments have been detected respectively in 7.5%, 2.8% and 2.8% of patients. Patients with CT showed a significantly lower age at onset of MDD than "pure" MDD patients (31.9 vs. 40.9 years; p=0.049) and higher rates of family history of bipolar disorder in first degree relatives (15.4% vs. 0%; p=0.001). LIMITATIONS The major limitation of this study was the lack of a group of bipolar depressives, which would have been useful in order to confirm the similarities of age at onset and bipolar family history with cyclothymic MDD. CONCLUSIONS Our data confirm previous reports in a sample of accurately screened patients with unipolar major depression: we found that patients with a cyclothymic temperament had an earlier age at onset and a higher family history for bipolar disorder than patients without any dominant affective temperament. Further research is needed to ascertain whether patients with "unipolar" cyclothymic MDD respond to mood stabilizers.

Abstract
Variations in voltage-dependent calcium channel L-type, alpha 1C subunit (CACNA1C) gene have been associated with bipolar disorder in a recent meta-analysis of genome-wide association studies [Ferreira et al., 2008]. The impact of these variations on other psychiatric disorders has not been yet investigated. Caucasian non-Hispanic participants in the STAR*D study of treatment for depression for whom DNA was available (N = 1213) were genotyped at two single-nucleotide polymorphisms (SNPs) (rs10848635 and rs1006737) in the CACNA1C gene. We examined putative phenotypic indicators of bipolarity among patients with major depression and elements of longitudinal course suggestive of latent bipolarity. We also considered remission and depression severity following citalopram treatment. The rs10848635 risk allele was significantly associated with lower levels of baseline agitation (P = 0.03; beta = -0.09). The rs1006737 risk allele was significantly associated with lesser baseline depression severity (P = 0.04; beta = -0.4) and decreased likelihood of insomnia (P = 0.047; beta = -0.22). Both markers were associated with an increased risk of citalopram-emergent suicidality (rs10848635: OR = 1.29, P = 0.04; rs1006737: OR = 1.34, P = 0.02). In this exploratory analysis, treatment-emergent suicidality was associated with two risk alleles in a putative bipolar liability gene.

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.

Abstract
The current categorical splitting of bipolar and depressive disorders has been questioned. Age at onset is an important variable used to support such a division. Study aim was to assess the distribution of age at onset between bipolar II disorder (BP-II) and major depressive disorder (MDD), and onset age-bipolar family history, onset age-BP-II diagnosis dose-response relationships. No bi-modal distribution and no presence of dose-response relationships would not support a categorical distinction between BP-II and MDD. Consecutive 389 BP-II and 261 MDD major depressive episode (MDE) outpatients were interviewed with the DSM-IV Structured Clinical Interview and the Family History Screen, by a mood specialist psychiatrist in a private practice. Age at onset was defined as age at onset of the first MDE. Distribution of age at onset between BP-II and MDD was studied by Kernel density estimate and histogram methods, dose-response relationships by ROC analysis. BP-II, versus MDD, had significantly lower age at onset, more recurrences, and more bipolar family history. Kernel density estimate and histogram distributions of age at onset showed no bi-modality. Likelihood ratios between age at onset and bipolar family history loading, and between age at onset and BP-II diagnosis, showed dose-response relationships. The bi-modality and dose-response approaches, versus classic diagnostic validators, seem to support a dimensional relationship between BP-II and MDD.

Abstract
BACKGROUND Recent studies questioned the current categorical split of mood disorders into bipolar disorders (BP) and depressive disorders (MDD). METHODS Medline database search of papers from the last 10 years on the categorical-dimensional classification of mood disorders. Various combinations of the following key words were used: mood disorders, bipolar, unipolar, major depressive disorder, spectrum, category/categorical, classification, continuity. Only English language clinical papers were included, review papers were excluded, similar papers selected by quality. The number of papers found was 1,141. The number of papers selected was 109. RESULTS The continuity/spectrum between BP (mainly BP-II) and MDD was supported by the following findings:(1) high frequency of mixed states (mixed mania, mixed hypomania, mixed depression, i.e. co-occurring depression and noneuphoric manic/hypomanic symptoms) because opposite polarity symptoms in the same episode do not support a hypomania/mania-depression splitting; (2) MDD was the most common mood disorder in BP probands' relatives; (3) no bimodal distribution of distinguishing symptoms between BP and MDD; (4) bipolar signs not uncommon in MDD; (5) many MDD shifting to BP; (6) many lifetime manic/hypomanic symptoms in MDD; (7) correlation between lifetime manic/hypomanic symptoms and MDD symptoms; (8) hypomania factors in MDD; (9) MDD often recurrent; (10) similar cognitive style. The categorical distinction between BP (mainly BP-I) and MDD was supported by the following findings: (1) BP more common in BP probands' relatives; (2) lower age at BP onset; (3) females as common as males in BP-I, more common than males in MDD; (4) BP-I depression more atypical and retarded, MDD depression more sleepless and agitated; (5) BP more recurrent. CONCLUSIONS Focusing on mood spectrum's extremes (BP-I vs. MDD), a categorical distinction seems supported. Focusing on midway disorders (BP-II and MDD plus bipolar signs), a continuity/spectrum seems supported. Results seem to support both a categorical and a dimensional view of mood disorders.

Abstract
Diagnosis and treatment of bipolar disorder has long been a neglected discipline. Recent years have shown an upsurge in bipolar research. When compared to major depressive disorder, bipolar research still remains limited and more expert based than evidence based. In bipolar diagnosis the focus is shifting from classic mania to bipolar depression and hypomania. There is a search for bipolar signatures in symptoms and course of major depressive episodes. The criteria for hypomania are softened, leading to a bipolar prevalence that now equals that of major depressive disorder. Anti-epileptics and atypical antipsychotics have joined lithium in the treatment of bipolar disorder. Fortunately, mood stabilization has become the core issue in bipolar disorder treatment. In contrast with recent trends in the diagnosis of bipolar disorder, treatment research remains more focused on classic mania than depression or hypomania. This leaves the clinician with the difficult task of diagnosing 'new bipolar patients' for whom no definite evidence-based treatment is available. An important efficacy-effectiveness gap further compromises the translation of the evidence base on bipolar disorder treatment into clinical practice. The recent upsurge of research on bipolar disorder is to be applauded, but further research is needed: for bipolar disorder in general, and for bipolar depression and the long-term treatment specifically. Given the complexity of the disorder and the many clinical uncertainties, effectiveness studies should be installed.

Abstract
Bipolar and unipolar disorders share a common depressive clinical manifestation. It is important to distinguish between these two forms of depression for several reasons. First, prescribing antidepressors in monotherapy indubitably worsens the prognosis of bipolarity disorders. Second, postponing the prescription of a mood stabilizer reduces the efficacy of the treatment and multiplies the suicidal risks by two. The object of this study is to reveal the factors that distinguish between unipolar and bipolar depression. This is a retrospective study on patients' files. It includes 186 patients divided according to DSM IV criteria into two groups: patients with bipolar disorder type I or II with a recent depressive episode (123 patients) and patients with recurrent depressive disorder (63 patients). A medical record card was filled-in for every patient. It included socio-demographic data, information about the disorder, family antecedents, CGI score (global clinical impressions), physical comorbidity, substance abuse and personality disorder. In order to sort out the categorization variables, the two groups were compared using chi2 test or Fischer's test. With regard to the quantitative variables, the two groups were compared using Krostal Wallis's test or Ancova. Our study has revealed that bipolar disorder differs significantly from unipolar disorder in the following respects: bipolar disorder is prevalent among men (sex-ratio 2) while unipolar disorder is prevailing among women (sex-ratio 0.8); patients with bipolar disorder are younger than patients with unipolar disorder (38.1 +/- 5 years vs. 49.7 +/- years); the age at the onset of bipolar disorder is earlier than that of unipolar disorder (20.8 +/- 2 years vs. 38.7 +/- 5 years); family antecedents are more important in bipolar patients than in unipolar patients (51.1% vs. 33%). More importantly, bipolar disorder differs from unipolar disorder in the following aspects: The number of suicidal attempts (25.3% vs. 23.6%); the degree of substance abuse (15.4% vs. 14.5%); the level of somatic comorbidity (20.3% vs. 17.4%); the amount of anxiety manifestations (5.6% vs. 4.8%); the extent of personality disorder (30.8% vs. 23.8%); the degree of socio-professional impairment (bachelorhood and unemployment). On the other hand, we noted that unipolar patients differ from bipolar patients in terms of the frequency of hospitalizations (3.5 vs. 3.1) and the length of stays in hospitals (25.8 vs. 20.7 days) with significant differences of 0.003 and 0.0000001 respectively. Moreover, the CGI scores of unipolar patients are higher than those of bipolar patients. However, the difference is not significant. Consequently, an early distinction between bipolar and unipolar disorder is of utmost importance for the treatment of these two illnesses.

Abstract
A quantitative examination was made of the association of parental mood and anxiety disorders with severity of disability within a large sample of young children with Pervasive Developmental Disorder (PDD). Maternal recurrent mood disorders were associated with elevated cognitive and adaptive functioning in their affected children, parent reports of increased behavior problems and teacher reports of an internalizing behavioral style. Maternal histories of anxiety disorders and paternal depression or anxiety disorders were not associated with levels of adaptive/cognitive functioning or levels of maladaptive behaviors in the children. Various genetic models are discussed. It is hypothesized that genes associated with recurrent depression in women may exert a "protective" effect on cognition and adaptive functioning in children with PDD.

Abstract
PURPOSE OF REVIEW The aim of this review is to highlight recent studies that have questioned the current split of mood disorders into the categories of bipolar and depressive disorders. RECENT FINDINGS A continuity between bipolar disorders (mainly bipolar II disorder) and major depressive disorder was supported by several lines of evidence: depressive mixed states (mixed depression) and dysphoric (mixed) hypomania (opposite polarity symptoms in the same episode do not support the splitting between mania/hypomania and depression); family history, major depressive disorder is the most common mood disorder in relatives of bipolar probands; lack of points of rarity between the depressive syndromes of bipolar II disorder and major depressive disorder; bipolar features in major depressive disorder; major depressive disorder shifting to bipolar disorders; history of manic/hypomanic symptoms in major depressive disorder and correlation between lifetime manic/hypomanic symptoms and depressive symptoms in major depressive disorder; factors of hypomania inside major depressive disorder; recurrent course of major depressive disorder; depression more common than mania and hypomania in bipolar disorders; trait mood lability in major depressive disorder. SUMMARY This review of the recent findings on the relationship between bipolar disorders (especially bipolar II disorder) and depressive disorders seems to support a continuity among mood disorders, and runs against the current classification of mood disorders dividing them into independent categories. Further research is needed in the area, in part because of its possible treatment impact.

Abstract
Recent studies have questioned current diagnostic systems that split mood disorders into the independent categories of bipolar disorders and depressive disorders. The current classification of mood disorders runs against Kraepelin's unitary view of manic-depressive insanity (illness). The main findings of recent studies supporting a continuity between bipolar disorders (mainly bipolar II disorder) and major depressive disorder are presented. The features supporting a continuity between bipolar II disorder and major depressive disorder currently are 1) depressive mixed states (mixed depression) and dysphoric (mixed) hypomania (opposite polarity symptoms in the same episode do not support a splitting of mood disorders); 2) family history (major depressive disorder is the most common mood disorder in relatives of bipolar probands); 3) lack of points of rarity between the depressive syndromes of bipolar II disorder and major depressive disorder; 4) major depressive disorder with bipolar features such as depressive mixed states, young onset age, atypical features, bipolar family history, irritability, racing thoughts, and psychomotor agitation; 5) a high proportion of major depressive disorders shifting to bipolar disorders during long-term follow-up; 6) a high proportion of major depressive disorders with history of manic and hypomanic symptoms; 7) factors of hypomania present in major depressive disorder episodes; 8) recurrent course of major depressive disorder; and 9) depressive symptoms much more common than manic and hypomanic symptoms in the course of bipolar disorders.

Abstract
OBJECTIVE To investigate the characteristics of unipolar vs. bipolar depression in youth using a sample of children referred for a study on attention deficit hyperactivity disorder (ADHD). METHODS We compared children with unipolar depression (N=109) to those with bipolar depression (N=43) using boys and girls (N=280) referred for a study on ADHD. Comparisons were made in characteristics of depression, comorbidity and family history. All diagnoses were made using the KSADS-E. RESULTS In comparison to children with unipolar depression, children with bipolar depression were more likely to have met criteria for depression due to both "sad" and "mad" mood states as stated in the KSADS-E, have severe depression with suicidality, anhedonia and hopelessness. Children with bipolar depression were more likely to have comorbid conduct disorder, severe oppositional defiant disorder, agoraphobia, obsessive compulsive disorder and alcohol abuse, compared to children with unipolar depression. Bipolar depressed children had lower GAF scores and higher rates of hospitalization. Bipolar depression is associated with higher levels of psychiatric disorders in first-degree relatives. CONCLUSIONS In youth, bipolar depression is distinct from unipolar depression in quality and severity of symptoms, comorbidity and family history. This presentation can aid clinicians in identifying children and adolescents with bipolar disorder.

Abstract
This article addresses the question whether borderline personality disorder (BPD) can be understood as a variant of bipolar disorder. In the past, borderline pathology has been seen as a variant of psychosis, depression, or posttraumatic stress disorder, but there are important differences between all of these conditions and BPD. The proposal that BPD falls within the bipolar spectrum depends on the assumption that affective instability develops through the same mechanism in both diagnostic categories. There are major differences in phenomenology, family history, longitudinal course, and treatment response between BPD and bipolar disorder, and the findings of comorbidity studies are equivocal. Thus, existing evidence is insufficient to support the concept that BPD falls in the bipolar spectrum.
