Abstract
Several lines of evidence have raised the question of whether Borderline Personality Disorder (BPD) is an independent disease entity or it might be better conceptualized as belonging to the spectrum of mood disorders. This study explores a wide array of lifetime mood features (mood, cognitions, energy, and rhythmicity and vegetative functions) in patients with BP and mood disorders. The sample consisted of 25 BPD patients who did not meet the criteria for bipolar disorders, 16 bipolar disorders patients who did not meet the criteria for BPD, 19 unipolar patients who did not meet the criteria for BPD, and 30 non-clinical subjects. Clinical diagnoses were determined by administering the structured clinical interviews for DSM-IV disorders. The Mood Spectrum Self-Report (MOODS-SR) was used for measuring lifetime mood phenomenology. Clinical subjects displayed higher mean scores than normal subjects in all domains of the MOODS-SR, and BPD patients displayed higher scores than unipolar patients in the Mood and Cognition depressive subdomains. Differences between patients with BP and bipolar disorders on MOODS psychopathology did not attain statistical significance for any (sub)domain considered. The results of this study are consistent with previous findings suggesting the importance of mood dysregulations in patients with BPD.

Abstract
OBJECTIVES Although aggressive behavior has been associated with bipolar disorder (BD), it has also been linked with developmental factors and disorders frequently found to be comorbid with BD, making it unclear whether or not it represents an underlying biological disturbance intrinsic to bipolar illness. We therefore sought to identify predictors of trait aggression in a sample of adults with BD. METHODS Subjects were 100 bipolar I (n = 73) or II (n = 27) patients consecutively evaluated in the Bipolar Disorders Research Program of the New York Presbyterian Hospital-Payne Whitney Clinic. Diagnoses were established using the Structured Clinical Interview for the DSM-IV (SCID-I) and Cluster B sections of the SCID-II. Mood severity was rated by the Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS). Histories of childhood maltreatment were assessed via the Childhood Trauma Questionnaire (CTQ), while trait aggression was measured by the Brown-Goodwin Aggression Scale (BGA). RESULTS In univariate analyses, significant relationships were observed between total BGA scores and CTQ total (r = 0.326, p = 0.001), childhood emotional abuse (r = 0.417, p < 0.001), childhood physical abuse (r = 0.231, p = 0.024), childhood emotional neglect (r = 0.293, p = 0.004), post-traumatic stress disorder (t = -2.843, p = 0.005), substance abuse/dependence (t = -2.914, p = 0.004), antisocial personality disorder (t = -2.722, p = 0.008) and borderline personality disorder (t = -5.680, p < 0.001) as well as current HDRS (r = 0.397, p < 0.001) and YMRS scores (r = 0.371, p < 0.001). Stepwise multiple regression revealed that trait aggression was significantly associated with: (i) diagnoses of comorbid borderline personality disorder (p < 0.001); (ii) depressive symptoms (p = 0.001); and (iii) manic symptoms (p < 0.001). CONCLUSIONS Comorbid borderline personality disorder and current manic and depressive symptoms each significantly predicted trait aggression in BD, while controlling for confounding factors. The findings have implications for nosologic distinctions between bipolar and borderline personality disorders, and the developmental pathogenesis of comorbid personality disorders as predisposing to aggression in patients with BD.

Six-month prospective life charting of mood symptoms with lamotrigine monotherapy versus placebo in rapid cycling bipolar disorder. Biol Psychiatry 2008; 63:125-30.

Abstract
BACKGROUND Fluctuations in mood are quintessential features of bipolar disorder; however, previous studies have seldom examined the extent to which pharmacotherapies for bipolar disorder may reduce or ameliorate daily or weekly mood variability. The anticonvulsant lamotrigine has demonstrated efficacy for relapse prevention in bipolar disorder, but its possible mood-stabilizing properties on a day-to-day or week-to-week basis have not previously been investigated. METHODS Weekly mood shifts were examined over 26 weeks using patients' self-reported prospective Life Chart Method (LCM) data obtained as part of a previously reported randomized relapse prevention comparison of lamotrigine monotherapy or placebo in 182 bipolar patients with DSM-IV rapid cycling. Generalized estimating equation (GEE) analyses were used to compare treatment arms for subjects who achieved euthymia across weeks. RESULTS After adjusting for potential confounding factors, a final GEE model revealed that subjects taking lamotrigine were 1.8 times more likely than those taking placebo to achieve euthymia, as measured by LCM, at least once per week over 6 months (95% confidence interval [CI] = 1.03-3.13). Subjects taking lamotrigine had an increase of .69 more days per week euthymic as compared with those taking placebo (p = .014). CONCLUSIONS Achievement of euthymia across weeks represents a novel paradigm shift in gauging the mood-stabilizing properties of a psychotropic agent. The present findings demonstrate the utility of the prospective Life Chart Method for assessing longitudinal mood stability during randomized clinical trials for bipolar disorder. The results lend support to the potential mood-stabilizing properties of lamotrigine monotherapy for bipolar disorder.

Abstract
Bipolar disorder is common, and both difficult to detect and diagnose. Treatment is contingent on clinical needs, which differ according to phase and stage of the illness. A staging model could allow examination of the longitudinal course of the illness and the temporal impact of interventions and events. It could allow for a structured examination of the illness, which could set the stage for algorithms that are tailored to the individuals needs. A staging model could further provide as structure for assessment, gauging treatment and outcomes. The model incorporates prodromal stages and emphasizes early detection and algorithm appropriate intervention where possible. At the other end of the spectrum, the model attempts to operationalize treatment resistance. The utility of the model will need to be validated by empirical research.

Abstract
Outcome in bipolar patients is affected by comorbidity. Comorbid personality disorders are frequent and may complicate the course of bipolar illness. This pilot study examined a series of 40 euthymic bipolar patients (DSM-IV criteria) (bipolar I disorder 31, bipolar II disorder 9) to assess the effect of clinical variables and the influence of comorbid personality on the clinical course of bipolar illness. Bipolar patients with a diagnosis of comorbid personality disorder (n = 30) were compared with "pure" bipolar patients (n = 10) with regard to demographic, clinical, and course of illness variables. Comorbid personality disorder was diagnosed in 75% of patients according to ICD-10 criteria, with obsessive-compulsive personality disorder being the most frequent type. Sixty-three per cent of subjects had more than one comorbid personality disorder. Bipolar patients with and without comorbid personality disorder showed no significant differences regarding features of the bipolar illness, although the group with comorbid personality disorder showed a younger age at onset, more depressive episodes, and longer duration of bipolar illness. In subjects with comorbid personality disorders, the number of hospitalizations correlated significantly with depressive episodes and there was an inverse correlation between age at the first episode and duration of bipolar illness. These findings, however, should be interpreted taking into account the preliminary nature of a pilot study and the contamination of the sample with too many bipolar II patients.

Abstract
OBJECTIVE This review examines whether borderline personality disorder (BPD) should be considered part of the bipolar spectrum. METHODS A literature review examined studies of co-occurrence, phenomenology, family prevalence, medication response, longitudinal course, and etiology. RESULTS Borderline personality disorder and bipolar disorder co-occur, but their relationship is not consistent or specific. There are overlaps but important differences in phenomenology and in medication response. Family studies suggest clear distinctions, and it is unusual for BPD to evolve into bipolar disorder. Research is insufficient to establish whether these disorders have a common etiology. CONCLUSIONS Existing data fail to support the conclusion that BPD and bipolar disorders exist on a spectrum but allows for the possibility of partially overlapping etiologies.

Abstract
The present research compared recent suicide attempters with and without a diagnosis of Borderline Personality Disorder (BPD). One hundred and eighty recent suicide attempters, recruited in the Emergency Department, participated in extensive research interviews. Results showed that suicide attempters with BPD displayed greater severity of overall psychopathology, depression, hopelessness, suicidal ideation, past suicide attempts, and had poorer social problem solving skills than those without a BPD diagnosis. No differences were found between the groups regarding the intent to die or lethality associated with the index suicide attempt. These findings highlight the seriousness of BPD and the risk that individuals diagnosed with this disorder will attempt suicide.

Abstract
The goal of this paper is to review assessment research of bipolar disorder in children and adolescents. The review addresses numerous themes: the benefits and costs of involving clinical judgment in the diagnostic process, particularly with regard to diagnosis and mood severity ratings; the validity of parent, teacher, and youth self-report of manic symptoms; how much cross-situational consistency is typically shown in mood and behavior; the extent to which a parent's mental health status influences their report of child behavior; how different measures compare in terms of detecting bipolar disorder, the challenges in comparing the performance of measures across research groups, and the leading candidates for research or clinical use; evidence-based strategies for interpreting measures as diagnostic aids; how test performance changes when a test is used in a new setting and what implications this has for research samples as well as clinical practice; the role of family history of mood disorder within an assessment framework; and the implications of assessment research for the understanding of phenomenology of bipolar disorder from a developmental framework.

Abstract
Because of the difficulties of ascertaining episode of hypomania by past history of the patients, it is of clinical value to find variables which predict the development of bipolar II disorder in depressive patients. Taking advantage of relatively long hospitalization, the authors tried to elucidate fine clinical features of the soft bipolarity. The subjects were 39 patients with Major Depressive Episode, diagnosed according to the 4th edition of the Diagnostic and Statistical Manual criteria. Among them, 15 patients were diagnosed as bipolar II disorder (BPII), whereas 24 patients were with unipolar depression (UP), using a structured clinical interview to assess the mood spectrum (SCI-MOODS). In addition to ordinary clinical and demographic variables, the authors studied fine symptomatology of depression, premorbid personality, and interpersonal relationship. Continuous variables were analyzed by t-test. Categorical variables were tested by chi2 analysis. In terms of premorbid personality, manic type (Zerssen) was found more frequently in BPII (UP 2/24, BPII 9/15, P < 0.05). Patients with BPII tended to show apparently quick disappearance of depressive symptoms (UP 2/24, BPII 9/15, P = 0.01). The most prominent result was a high prevalence of comorbidity of borderline personality disorder (BPD) among BPII (UP 0/24, BPII 6/15, P = 0.02). As Akiskal indicated that mood lability represents the most powerful predictor of hypomanias, patients with BPII showed quick response in mood to admission. The current subjects with BPII had high frequency of manic type of premorbid personality, indicating the usefulness of this variable for the prediction of hypomanias. Finally, the authors could observe development of BPD during hospitalization exclusively among BPII, to support the possibility of BPD as a state effect of BPII.

Abstract
BACKGROUND Despite a plethora of studies, controversies abound on whether the long-term traits of unipolar and bipolar patients could be differentiated by temperament and whether these traits, in turn, could be distinguished from subthreshold affective symptomatology. METHODS 98 bipolar I (BP-I), 64 bipolar II (BP-II), and 251 unipolar major depressive disorder (UP-MDD) patients all when recovered from discrete affective episodes) and 617 relatives, spouses or acquaintances without lifetime RDC diagnoses (the comparison group, CG) were administered a battery of 17 self-rated personality scales chosen for theoretical relevance to mood disorders. Subsamples of each of the four groups also received the General Behavior Inventory (GBI). RESULTS Of the 436 personality items, 103 that significantly distinguished the three patient groups were subjected to principal components analysis, yielding four factors which reflect the temperamental dimensions of "Mood Lability", "Energy-Assertiveness," "Sensitivity-Brooding," and "Social Anxiety." Most BP-I described themselves as near normal in emotional stability and extroversion; BP-II emerged as labile in mood, energetic and assertive, yet sensitive and brooding; MDD were socially timid, sensitive and brooding. Gender and age did not have marked influence on these overall profiles. Within the MDD group, those with baseline dysthymia were the most pathological (i.e., high in neuroticism, insecurity and introversion). Selected GBI items measuring hypomania and biphasic mood changes were endorsed significantly more often by BP-II. Finally, it is relevant to highlight a methodologic finding about the precision these derived temperament factors brought to the UP-BP differentiation. Unlike BP-I who were low on neuroticism, both BP-II and UP scored high on this measure: yet, in the case of BP-II high neuroticism was largely due to mood lability, in UP it reflected subdepressive traits. LIMITATION We used self-rated personality measures, a possible limitation generic to the paper-and-pencil personality literature. It is therefore likely that BP-I may have over-rated their "sanguinity"; or should one consider such self-report as a reliable reflection of one's temperament? One can raise similar unanswerable questions about "depressiveness" and "mood lability." CONCLUSION As contrasted to CG and published norms, the postmorbid self-described "usual" personality is 1) sanguine among many, but not all, BP-I; 2) labile or cyclothymic among BP-II; and 3) subanxious and subdepressive among UP. It is further noteworthy that with the exception of BP-II, the temperament scores of BP-I and MDD were within one SD from published norms. Rather than being pathological, these attributes are best conceived as subclinical temperamental variants of the normal, thereby supporting the notion of continuity between interepisodic and episodic phases of affective disorders. These findings overall are in line with Kraepelin's views and contrary to the DSM-IV formulation of axis-II constructs as being pathological and sharply demarcated from affective episodes.

Abstract
Borderline Personality Disorder (BPD) is a common, disabling, and burdensome psychiatric condition. It is characterized by turbulent fluctuations of negative emotions and moods, unstable and conflictual interpersonal relationships, an incoherent and often contradictory sense of self, and impulsive, potentially lethal self-injurious behaviors. The neurobehavioral facets of BPD have not been extensively studied. However, clinical theoreticians and researchers have proposed that the symptoms and behaviors of BPD are, in part, associated with disruptions in basic neurocognitive processes. This review summarizes and evaluates research that has investigated the relationship between executive neurocognition, memory systems, and BPD. Three historical phases of research are delineated and reviewed, and the methodological and conceptual challenges this body of investigation highlights are discussed. Laboratory-based assessment of executive neurocognition and memory systems is integral to an interdisciplinary approach to research in BPD. Such an approach holds promise in elucidating the neurobehavioral facets, development, diagnostic boundaries, prevention, and optimal interventions for this debilitating and enigmatic disorder.

Abstract
In studies made in the last decade, patients consulting doctors because of depression and anxiety have very often turned out to suffer from bipolar type II and similar conditions with alternating depression and hypomania/mania (the bipolar spectrum disorders - BP). Specifically, about every second patient seeking consultation because of depression has been shown to suffer from BP, mainly bipolar type II. BP is often concealed by other psychiatric conditions, e.g. recurrent depression, psychosis, anxiety, addiction, personality disorder, attention-deficit hyperactivity disorder and eating disorder. BP shows strong heredity. Relatives of patients with BP also have a high frequency of the psychiatric conditions just mentioned. Conversion ("switching") from recurrent unipolar depressions (recurrent UP) to BP is common in very long longitudinal studies (over decades). Mood-stabilizing medicines are recommended to a great extent in the treatment of BP, since anti-depressive medicines are often not effective and involve a substantial risk of inducing mood swings. Particularly in the long-term pharmacological treatment of depression in BP anti-depressive medicines may worsen the condition, e.g. inducing a symptom triad of dysphoria, irritability and insomnia: ACID (antidepressant-associated chronic irritable dysphoria).

Abstract
BACKGROUND In young adults it can be difficult to differentiate between an early bipolar illness and borderline personality disorder. There are considerable areas of clinical overlap between cyclothymic temperament, bipolar-spectrum disorders and borderline characteristics. The aim of this study was to measure borderline characteristics in young adults during an index depressive episode and to compare three diagnostic groups: DSM-IV bipolar affective disorder (BPAD); bipolar spectrum disorder (BSD); and DSM-IV recurrent major depressive disorder (MDD). METHODS Eighty-seven young adults with a current episode of major depression and at least one previous episode of depression were recruited from consecutive referrals to a psychiatric clinic. Diagnoses were based on the Structured Clinical Interview for DSM-IV (SCID-1) and recently proposed structured diagnostic criteria for BSD. All patients also completed the borderline questions from the screening questionnaire of the International Personality Disorders Examination (IPDE). RESULTS Diagnostically, the cohort of 87 patients divided into three groups: 14 with BPAD; 27 with BSD; and 46 with MDD. None of the subjects fulfilled DSM-IV or ICD-10 diagnostic criteria for personality disorder and all three groups were well matched in terms of age, gender distribution, ethnicity, socioeconomic and educational status, age at onset of illness, and severity of index depressive episode. Both of the bipolar-depressed groups reported significantly higher median levels of borderline characteristics than the MDD group (p<0.0001). Three of the borderline characteristics emerged as potentially useful in differentiating bipolar depression from unipolar depression: 'I've never threatened suicide or injured myself on purpose' (sensitivity=0.93; positive predictive value [PPV]=56.7); 'I have tantrums or angry outbursts' (sensitivity 0.66; PPV=65.6%); and 'Giving in to some of my urges gets me into trouble' (sensitivity=0.76; PPV=59.6%). LIMITATIONS All of the subjects were recruited from a university health service clinic and as such are unlikely to be representative of patients from more diverse socio-economic backgrounds. No structured diagnostic assessment of personality disorder was administered. The diagnostic criteria for BSD are not yet fully validated. CONCLUSIONS Young adults with bipolar depression exhibit significantly higher levels of borderline personality pathology than those with unipolar depression. Those borderline screening questions that reflect cyclothymic characteristics or depressive mixed states may be of practical use to clinicians in helping to differentiate between bipolar depression and unipolar depression in young adults.

Abstract
BACKGROUND Current data indicate a strong association between Cyclothymic temperament (and its more ultradian counterpart of mood lability) and Bipolar II (BPII). Administration of elaborate measures of temperament are cumbersome in routine practice. Accordingly, the aim of the present analyses was to test if a practical measure of mood lability was unique to BPII, in comparison with major depressive disorder (MDD). METHODS Using the Structured Clinical Interview for DSM-IV Axis I Disorders, Clinician Version as modified by us [J. Affect. Disord. 73 (2003) 33; Curr. Opin. Psychiatry 16 (2003) S71], we interviewed 62 consecutive BPII outpatients, as well as their 59 MDD counterparts during a major depressive episode (MDE). Hypomanic symptoms during MDE were systematically assessed: three or more such symptoms defined depressive mixed state (DMX3) on the basis of previous work by us [J. Affect. Disord. 73 (2003) 113]. A downscaled definition of trait mood lability was adapted from Akiskal et al. [Arch. Gen. Psychiatry 52 (1995) 114] and Angst et al. [J. Affect. Disord. 73 (2003) 133], requiring a positive response to one of two queries on whether one is a person with frequent "ups and downs" in mood, and whether such mood swings occur for no reason. The patients selected for inclusion had not received neuroleptics and antidepressants for at least 2 weeks prior to the index episode, they were free of substance and alcohol abuse, and did not meet the DSM-IV criteria for borderline personality disorder (BPD). Associations between mood swings and clinical variables were tested by logistic regression (STATA 7). RESULTS Mood swings were endorsed by 50.4% of the entire sample: 62.9% of BPII and 37.2% of MDD (p = 0.0047). This practical measure of mood lability was significantly associated with BPII, lower age at onset, high depressive recurrences, atypical features, and DMX3. When controlled for number of major affective episodes, mood swings were still significantly associated with BP-II. Sensitivity and specificity of mood swings for predicting BPII were 62.9% and 62.7%, respectively. LIMITATION The low specificity of trait mood lability for BPII diagnosis is probably due to the fact that we used a downscaled simplified measure of this trait. CONCLUSIONS On the other hand, the relatively high sensitivity of our downscaled measure of mood lability for predicting BPII supports its usefulness as a screening tool for this diagnosis. The lack of association between self-reported mood lability and number of major mood episodes indicates that such lability does not reflect the perception of history of frequent episodes, and that it has some validity as a trait indicator. Given that our sample excluded patients meeting the DSM-IV criteria for BPD, contradicts the opinion of the latter manual that such mood lability represents its pathognomonic characteristic that distinguishes it from BPII. The bipolar nature of mood lability is further supported by significant associations with external validating criteria for bipolarity. Overall, these data indicate that in the differential diagnosis between MDD and BPII, trait mood lability favors the latter at a significant statistical level.

Akiskal HS. Searching for behavioral indicators of bipolar II in patients presenting with major depressive episodes: the "red sign," the "rule of three" and other biographic signs of temperamental extravagance, activation and hypomania. J Affect Disord 2005; 84:279-90. [PMID: 15708427 DOI: 10.1016/j.jad.2004.06.002] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2004] [Accepted: 06/03/2004] [Indexed: 11/21/2022]
Abstract
BACKGROUND Since 1977, the work of the author has shown the primacy of behavioral activation, flamboyance, and extravagance in detecting hypomania, the historical hallmark of cyclothymic and the broader spectrum of bipolar II (BP-II) disorders. In other words, the soft spectrum is more likely to declare itself in behavioral rather than mood disturbances. The obligatory search for elation and related mood changes a la DSM-IV (and its interview form, the SCID) during the clinical interview is often doomed to failure, thereby "condemning" the patient to a unipolar diagnosis, and hence to sequential and often tragic failures with antidepressants or combinations thereof. METHODS To characterize behavioral signs of good specificity, though individually of low sensitivity for BP-II in patents presenting with major depression, the author undertook a chart review of over 1000 depressive patients he had examined extending over a period of nearly three decades. The Mood Clinic Data Questionnaire (MCDQ) used in the author's Memphis mood clinic permitted systematization of unstructured observations. BP-II had been independently confirmed by hypomania of > or =2 days and/or cyclothymia over the course of the index illness (both of which were validated by family history for bipolarity in earlier research in our clinic). RESULTS Triads of behavior or traits in the patients' biographical history-as well as in the biologic kin-involving polyglottism, eminence, creative achievement, professional instability, multiple substance/alcohol use, multiple comorbidity (axis I and axis II), multiple marriages, a broad repertoire of sexual behavior (including brief interludes of homosexuality), impulse control disorders, as well as ornamentation and flamboyance (with red and other bright colors dominating) were specific for BP-II. Temperamentally, many of these individuals thrive on activity-they are indeed "activity junkies." LIMITATION The reported findings pertain primarily to the differential diagnosis between BP-II and unipolar depression. Replication of the approach espoused herein will require quantification of the operational definitions of the observed phenomenology. CONCLUSION The findings, which make sense in an evolutionary model of the advantage that "dilute" bipolar traits confer to human biography and erotic life, suggest that such behavioral traits can be useful provisionally in assigning a depressive episode to the realm of the bipolar II spectrum. Overall, the perspective espoused in this paper indicates that temperamental excesses and, more generally, a biographical approach, represent a more coherent approach than hypomanic episodes in the diagnosis of BP-II patients. Finally, such a diagnostic approach underscores the importance of incorporating evolutionary considerations and principles in understanding the origin of affective disorders.

Abstract
OBJECTIVES To review the current knowledge of bipolar II disorder. METHODS Literature was reviewed after conducting a Medline search and a hand search of relevant literature. RESULTS Bipolar II disorder is a common disorder, with a prevalence of approximately 3-5%. Distinct clinical features of bipolar II disorder have been described. The key to diagnosis is the recognition of past hypomania, while depression is the typical presenting feature of the illness. This is responsible for a significant rate of missed diagnosis, and consequent management according to unipolar guidelines. It is unclear if bipolar II disorder is over-represented amongst resistant depression populations and if abrupt offset of antidepressant action is a phenomenon over represented in bipolar II disorder, reflecting induction of predominantly depressive cycling. A few mood-stabilizer studies available provide provisional suggestion of utility. A supportive role for psychosocial therapies is suggested, however, there is a sparsity of published studies specific to bipolar II disorder cohorts. A small number of short-term antidepressant trials have suggested efficacy, however, compelling long-term maintenance data is absent. CONCLUSIONS An emerging literature on the specific clinical signature and management of the disorder exists, however, this is disproportionately small relative to the epidemiology and clinical significance of the disorder.

Abstract
The study of Mozart's letters and biography leads us to reconsider the psychiatric disorders from which he suffered. Indeed, it seems that Mozart demonstrated depressive episodes, some of which were severe and corresponded to the criteria of the DSM-IV classification. However, the arguments put forward by other authors supporting the occurrence of manic or hypomanic episodes (thus constituting a bipolar disorder diagnosis) are not supported by sufficient historic proof. Indeed, the length of time that the behaviors suggesting manic symptoms lasted is not compatible with such a diagnosis. Rather, Mozart's mood swings and impulsive behavior correspond to some traits of a personality disorder, that is, for the most part, symptoms of the dependent personality disorder. Evidence for this diagnosis appears most notably in Mozart's reactions to his wife's absences, but also in occasional behaviors as well as mood lability. The divergences in the classification of Mozart's symptoms, either into the field of bipolar disorders or into that of personality disorders, are closely linked to the nosological uncertainties that are still a source of debate in today's psychiatric research. We discuss a means of overcoming this limitation by considering the concept of "soft bipolar spectrum," a conceptualization that corresponds to Mozart's psychiatric history.

Abstract
BACKGROUND The purpose of this review is to examine empirical evidence concerning critiques of the diagnosis of borderline personality disorder (BPD): for uncertain validity, and for overlap with other mental disorders. METHODS A review of the literature on the validity and comorbidity of BPD was conducted. RESULTS Since BPD is a complex multidimensional construct, its validity is inevitably problematic, but no more so than most other psychiatric diagnoses. The comorbidity of BPD is probably an artefact of the current classification system, and there is no convincing evidence that BPD is a variant of an Axis I disorder. CONCLUSIONS Although further research should lead to changes in classification, the diagnosis of BPD retains significant clinical utility.

Abstract
OBJECTIVE The boundary between borderline personality disorder (BPD) and bipolar disorder (BD) is a controversial subject. Clinically, it can be difficult to diagnose patients who present with both affective instability and impulsivity. This paper reviews concepts and challenges related to the overlap of these disorders. METHODS A Medline search was conducted, using the key words borderline personality disorder, bipolar disorder, affective disorder, and personality disorder. Reference lists from articles generated were also used. Publications from the last 20 years were considered. RESULTS Studies demonstrate a greater cooccurrence between these 2 disorders than between BPD and other Axis I disorders or between BD and other Axis II disorders. Some authors suggest that many patients diagnosed with BPD are better described as having BD, that the bipolar classification is too narrow, or that BPD should be considered a variant of affective disorders. Others present evidence supporting BPD as a valid construct. Hypotheses about the relation between the 2 disorders and suggestions for clinical practice are offered. CONCLUSIONS There appears to be sufficient evidence to consider BPD to be a valid diagnosis. Both disorders apply to heterogeneous populations, and their characteristics require further clarification. In diagnostically challenging situations, careful consideration of a patient's longitudinal history is essential. Future research will be important to ensure that our diagnostic classifications reflect clinically useful entities.

Abstract
Psychopharmacology is widely used in the treatment of borderline personality disorder. However, support for this form of treatment has been largely based on case reports, case series, and open-label clinical trials. This evidence-based review examines the most recent randomized controlled trials of psychopharmacology in the treatment of borderline personality disorder, with a goal of highlighting the most promising pharmacotherapy for use in current clinical practice, as well as for future large-scale research testing. The results and limitations of the randomized controlled trial data are presented along with case vignettes illustrating the complexity of the disorder and the heterogeneity of its treatment. To date, there is at least some evidence-based support for the use of antipsychotics (conventional and atypical), monoamine oxidase inhibitors, serotonin reuptake inhibitors, and omega-3 fatty acids in the treatment of borderline personality 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.

Abstract
In recent years, advances in the areas of both bipolar and borderline personality disorders have generated considerable interest in the clinical interface between these two conditions. Developments in the study of the neurobiology of borderline personality disorder suggest that many patients with this diagnosis have etiological features in common with those diagnosed with bipolar disorders. This claim is supported by new insights into the phenomenology of both disorders and by evidence that mood stabilizers are efficacious in the pharmacological management of borderline patients. This area of research is an important one because of the considerable morbidity and public health costs associated with borderline personality disorder. Since borderline patients can be so challenging to care for, it may be that a reframing of the disorder as belonging to the broad clinical spectrum of bipolar disorders holds benefits for patients and clinicians alike.

Abstract
Atualmente, vemos transformações no diagnóstico do Transtorno de Humor Bipolar (THB). A prática clínica exige conhecimento mais detalhado da correlação THB - outras doenças psiquiátricas. Nessa revisão não-sistemática, foram abordados aspectos diagnósticos do THB: a) histórico, b) Espectro Bipolar, c) Depressão Atípica (DeA) e Disforia Histeróide, d) Estados Mistos, e) relação THB-Transtornos de Ansiedade, f) relação com o diagnóstico de Transtorno de Personalidade Borderline (TPB), g) contraponto ao conceito de espectro bipolar. A doença é conhecida desde a Grécia Antiga. Os estudos baseados nas publicações de Hagop Akiskal expandem o diagnóstico para além dos critérios usualmente utilizados, criando o conceito de espectro bipolar. A alta prevalência de comorbidade entre THB e Transtornos de Ansiedade corroboram que ambos compartilham o mesmo substrato neurobiológico. O debate demonstra que não há consenso, expondo a fragilidade dos nossos métodos diagnósticos. Entretanto, a revisão mostra a utilidade de sempre considerar o THB como diagnóstico diferencial.

Abstract
OBJECTIVES Few studies have examined the question of how personality features impact outcome in bipolar disorder (BD), though results from extant work and studies in major depressive disorder suggest that personality features are important in predicting outcome. The primary purpose of this paper was to examine the impact of DSM-IV personality disorder symptoms on long-term clinical outcome in BD. METHODS The study used a 'life-charting' approach in which 87 BD patients were followed regularly and treated according to published guidelines. Outcome was determined by examining symptoms over the most recent year of follow-up and personality symptoms were assessed with the Structured Clinical Interview for DSM-IV (SCID-II) instrument at entry into the life-charting study. RESULTS Patients with better outcomes had fewer personality disorder symptoms in seven out of 10 disorder categories and Cluster A personality disorder symptoms best distinguished euthymic and symptomatic patients. CONCLUSIONS These results raise important questions about the mechanisms linking personality pathology and outcome in BD, and argue that conceptual models concerning personality pathology and BD need to be further developed. Treatment implications of our results, such as need for psychosocial interventions and treatment algorithms, are also described.

Abstract
OBJECTIVE Recent data, including our own, indicate significant overlap between atypical depression and bipolar II. Furthermore, the affective fluctuations of patients with these disorders are difficult to separate, on clinical grounds, from cyclothymic temperamental and borderline personality disorders. The present analyses are part of an ongoing Pisa-San Diego investigation to examine whether interpersonal sensitivity, mood reactivity and cyclothymic mood swings constitute a common diathesis underlying the atypical depression-bipolar II-borderline personality constructs. METHOD We examined in a semi-structured format 107 consecutive patients who met criteria for major depressive episode with DSM-IV atypical features. Patients were further evaluated on the basis of the Atypical Depression Diagnostic Scale (ADDS), the Hopkins Symptoms Check-list (HSCL-90), and the Hamilton Rating Scale for Depression (HRSD), coupled with its modified form for reverse vegetative features as well as Axis I and SCID-II evaluated Axis II comorbidity, and cyclothymic dispositions ('APA Review', American Psychiatric Press, Washington DC, 1992). RESULTS Seventy-eight percent of atypical depressives met criteria for bipolar spectrum-principally bipolar II-disorder. Forty-five patients who met the criteria for cyclothymic temperament, compared with the 62 who did not, were indistinguishable on demographic, familial and clinical features, but were significantly higher in lifetime comorbidity for panic disorder with agoraphobia, alcohol abuse, bulimia nervosa, as well as borderline and dependent personality disorders. Cyclothymic atypical depressives also scored higher on the ADDS items of maximum reactivity of mood, interpersonal sensitivity, functional impairment, avoidance of relationships, other rejection avoidance, and on the interpersonal sensitivity, phobic anxiety, paranoid ideation and psychoticism of the HSCL-90 factors. The total number of cyclothymic traits was significantly correlated with 'maximum' reactivity of mood and interpersonal sensitivity. A significant correlation was also found between interpersonal sensitivity and 'usual' and 'maximum' reactivity of mood. LIMITATION Correlational study. CONCLUSIONS Mood lability and interpersonal sensitivity traits appear to be related by a cyclothymic temperamental diathesis which, in turn, appears to underlie the complex pattern of anxiety, mood and impulsive disorders which atypical depressive, bipolar II and borderline patients display clinically. We submit that conceptualizing these constructs as being related will make patients in this realm more accessible to pharmacological and psychological interventions geared to their common temperamental attributes. More generally, we submit that the construct of borderline personality disorder is better covered by more conventional diagnostic entities.

Abstract
BACKGROUND The present analyses were designed to compare the clinical characteristics and long-term episode course of Bipolar-I and Bipolar-II patients in order to help clarify the relationship between these disorders and to test the bipolar spectrum hypothesis. METHODS The patient sample consisted of 135 definite RDC Bipolar-I (BP-I) and 71 definite RDC Bipolar-II patients who entered the NIMH Collaborative Depression Study (CDS) between 1978 and 1981; and were followed systematically for up to 20 years. Groups were compared on demographic and clinical characteristics at intake, and lifetime comorbidity of anxiety and substance use disorders. Subsets of patients were compared on the number and type of affective episodes and the duration of inter-episode well intervals observed during a 10-year period following their resolution of the intake affective episode. RESULTS BP-I and BP-II had similar demographic characteristics and ages of onset of their first affective episode. Both disorders had more lifetime comorbid substance abuse disorders than the general population. BP-II had a significantly higher lifetime prevalence of anxiety disorders in general, and social and simple phobias in particular, compared to BP-I. Intake episodes of BP-I were significantly more acutely severe. BP-II patietns had a substantially more chronic course, with significantly more major and minor depressive episodes and shorter inter-episode well intervals. BP-II patients were prescribed somatic treatment a substantially lower percentage of time during and between affective episodes. LIMITATIONS BP-I patients with severe manic course are less likely to be retained in long-term follow-up, whereas the reverse might be true for BP-II patients who are significantly more prone to depression (i.e., patients with less inclination to depression and with good prognosis may have dropped out in greater proportions); this could increase the gap in long term course characteristics between the two samples. The greater chronicity of BP-II may be due, in part, to the fact that the patients were prescribed somatic treatments substantially less often both during and between affective episodes. CONCLUSIONS The variety in severity of the affective episodes shows that bipolar disorders, similar to unipolar disorders, are expressed longitudinally during their course as a dimensional illness. The similarities of the clinical phenotypes of BP-I and BP-II, suggest that BP-I and BP-II are likely to exist in a disease spectrum. They are, however, sufficiently distinct in terms of long-term course (i.e., BP-I with more severe episodes, and BP-II more chronic with a predominantly depressive course), that they are best classified as two separate subtypes in the official classification systems.

Abstract
A literature review was performed to determine whether inter-episode symptoms are of clinical importance in the management of bipolar disorder. Inter-episode symptoms are easy to miss but observational studies confirm that they are related to impaired function and reduced survival to full relapse. Randomised, controlled trials with lithium carbonate, and two studies exploring psychological treatments to recognise and treat prodromal symptoms of manic or depressive relapse, suggest some inter-episode symptoms are worth recognising because they are associated with reduced manic relapse and improved function. A classification is proposed to inform attempts at management of inter-episode symptoms in bipolar disorder patients, both clinically, and for future research. However, promotion of well-being in bipolar disorder patients does not require all symptoms to be treated. In other patients, the presence of inter-episode symptoms may be a marker of resistance to treatment. Finally, the mechanism by which inter-episode symptoms might lead to relapse, or even lead directly to functional impairment, awaits convincing explanation and empirical support.

Abstract
The bipolar II spectrum represents the most common phenotype of bipolarity. Numerous studies indicate that in clinical settings this soft spectrum might be as common--if not more common than--major depressive disorders. The proportion of depressive patients who can be classified as bipolar II further increases if the 4-day threshold for hypomania proposed by the DSM-IV is reconsidered. The modal duration of hypomanic episodes is 2 days; highly recurrent brief hypomania is as short as 1 day, and when complicated by major depression, it should be classified as a variant of bipolar II. Another variant of the bipolar II pattern is represented by major depressive episodes superimposed on cyclothymic or hyperthymic temperamental characteristics. The literature is unanimous in supporting the idea that depressed patients who experience hypomania during antidepressant treatment belong to the bipolar II spectrum. So-called alcohol- or substance-induced mood disorders may have much in common with bipolar II spectrum disorders, in particular when mood swings outlast detoxification. Finally, many patients within the bipolar II spectrum, especially when recurrence is high and the interepisodic period is not free of affective manifestations, may meet criteria for personality disorders. This is particularly true for cyclothymic bipolar II patients, who are often misclassified as borderline personality disorder because of their extreme mood instability. Subthreshold mood lability of a cyclothymic nature seems to be the common thread that links the soft bipolar spectrum. The authors submit this to represent the endophenotype likely to be informative in genetic investigations. Mood lability can be considered the core characteristics of the bipolar II spectrum, and it has been validated prospectively as a sensitive and specific predictor of bipolar II outcome in major depressives. In a more hypothetical vein, cyclothymic-anxious-sensitive temperamental disposition might represent the mediating underlying characteristic in the complex pattern of anxiety, mood, and impulsive disorders that bipolar II spectrum patients display throughout much of their lifetimes. The foregoing conclusions, based on clinical experience and the research literature, challenge several conventions in the formal classificatory system (i.e., ICD-10 and DSM-IV). The authors submit that the enlargement of classical bipolar II disorders to include a spectrum of conditions subsumed by a cyclothymic-anxious-sensitive disposition, with mood reactivity and interpersonal sensitivity, and ranging from mood, anxiety, impulse control, and eating disorders, will greatly enhance clinical practice and research endeavors. Prospective studies with the requisite methodologic sophistication are needed to clarify further the relationship of the putative temperamental and developmental variables to the complex syndromic patterns described herein. The authors believe that viewing these constructs as related entities with a common temperamental diathesis will make patients in this realm more accessible to pharmacologic and psychological approaches geared to their common temperamental attributes. The authors submit that the use of the term "spectrum" is distinct from a simple continuum of subthreshold and threshold cases. The underlying temperamental dimensions postulated by the authors define the disposition for soft bipolarity and its variation and dysregulation in anxious disorders and dyscontrol in appetitive, mental, and behavioral disorders, much beyond affective disorders in the narrow sense.

Abstract
Until recently it was believed that no more than 1% of the general population has bipolar disorder. Emerging transatlantic data are beginning to provide converging evidence for a higher prevalence of up to at least 5%. Manic states, even those with mood-incongruent features, as well as mixed (dysphoric) mania, are now formally included in both ICD-10 and DSM-IV. Mixed states occur in an average of 40% of bipolar patients over a lifetime; current evidence supports a broader definition of mixed states consisting of full-blown mania with two or more concomitant depressive symptoms. The largest increase in prevalence rates, however, is accounted for by 'softer' clinical expressions of bipolarity situated between the extremes of full-blown bipolar disorder where the person has at least one manic episode (bipolar I) and strictly defined unipolar major depressive disorder without personal or family history for excited periods. Bipolar II is the prototype for these intermediary conditions with major depressions and history of spontaneous hypomanic episodes; current evidence indicates that most hypomanias pursue a recurrent course and that their usual duration is 1-3 days, falling below the arbitrary 4-day cutoff required in DSM-IV. Depressions with antidepressant-associated hypomania (sometimes referred to as bipolar III) also appear, on the basis of extensive international research neglected by both ICD-10 and DSM-IV, to belong to the clinical spectrum of bipolar disorders. Broadly defined, the bipolar spectrum in studies conducted during the last decade accounts for 30-55% of all major depressions. Rapid-cycling, defined as alternation of depressive and excited (at least four per year), more often arise from a bipolar II than a bipolar I baseline; such cycling does not in the main appear to be a distinct clinical subtype - but rather a transient complication in 20% in the long-term course of bipolar disorder. Major depressions superimposed on cyclothymic oscillations represent a more severe variant of bipolar II, often mistaken for borderline or other personality disorders in the dramatic cluster. Moreover, atypical depressive features with reversed vegetative signs, anxiety states, as well as alcohol and substance abuse comorbidity, is common in these and other bipolar patients. The proper recognition of the entire clinical spectrum of bipolarity behind such 'masks' has important implications for psychiatric research and practice. Conditions which require further investigation include: (1) major depressive episodes where hyperthymic traits - lifelong hypomanic features without discrete hypomanic episodes - dominate the intermorbid or premorbid phases; and (2) depressive mixed states consisting of few hypomanic symptoms (i.e., racing thoughts, sexual arousal) during full-blown major depressive episodes - included in Kraepelin's schema of mixed states, but excluded by DSM-IV. These do not exhaust all potential diagnostic entities for possible inclusion in the clinical spectrum of bipolar disorders: the present review did not consider cyclic, seasonal, irritable-dysphoric or otherwise impulse-ridden, intermittently explosive or agitated psychiatric conditions for which the bipolar connection is less established. The concept of bipolar spectrum as used herein denotes overlapping clinical expressions, without necessarily implying underlying genetic homogeneity. In the course of the illness of the same patient, one often observes the varied manifestations described above - whether they be formal diagnostic categories or those which have remained outside the official nosology. Some form of life charting of illness with colored graphic representation of episodes, stressors, and treatments received can be used to document the uniquely varied course characteristic of each patient, thereby greatly enhancing clinical evaluation.

Abstract
Although many studies of RCBD have been reported over the last 2 decades, knowledge remains limited. Higher incidence in women is the sole clearly replicated finding in most studies. This finding might be mediated by cyclothymia, a temperament that is of higher prevalence in women and that might be considered as a normal variant of RC. Many questions remain unanswered. Review of putative risk factors, such as hypothyroidism and treatment with antidepressants, provides no conclusive answers. There is clinical evidence to implicate both factors. In principle, the thyroid connection can be approached rationally, yet there seems to be no relationship between thyroid status and response to thyroid augmentation. For this reason and given the potential risks of long-term thyroid use, this strategy should not be the first one to be tried in RC. Cumulatively, naturalistic studies over the past 30 years have strongly implicated antidepressants in switching and cycle acceleration, yet the double-blind, controlled, prospective studies that are needed to provide definitive answers are unlikely to be conducted for ethical reasons discussed in this article. Bipolar family history of RC probands appears indistinguishable from non-RC probands, indicating that most likely RCBD does not breed true. Although RC seems to be more lithium resistant with less likelihood of being symptom-free after 2 to 5 years of follow-up, many of these patients nonetheless have resolution of the RC course. There is no marked difference in suicide rates. An association of RC with bipolar type II, D-M-I pattern and those who switch into mania or hypomania on antidepressants is a provocative possibility: Antidepressants might introduce RC by first inducing a switch during a depressive episode, creating a D-M-I pattern, a pattern that is poorly responsive to lithium, which eventually degenerates into RC. Again, this sequence might be mediated by the high prevalence of cyclothymia in bipolar II patients. Thus, data from phenomenology, family history, and long-term outcome do not support RC as a separate entity. RC appears to be a temporary complicated phase in the illness, not a stable feature. This was noted by Kraepelin: I think I am convinced that that kind of classification must of necessity wreck on the irregularity of the disease. The kind and duration of the attacks and the intervals by no means remain the same in the individual case but may frequently change, so that the case must be reckoned always to new forms. Data by Gottschalk et al testify to the chaotic mood swings of contemporary bipolar disorder. Moreover RC is seen in other medical diseases, such as epilepsy, in which patients have phases of increase in frequency of episodes (seizures) that become refractory to treatment. Further longitudinal prospective studies are required to understand the complexity of this intriguing phenomenon and to provide better treatments. Algorithms deriving from tertiary research or university-based clinical experience may not generalize to RC or otherwise treatment-resistant bipolar patients seen in more routine practice. Illness severity in RCBD generally precludes double-blind controlled investigations. Meanwhile, clinicians may rely on discontinuing antidepressants, maintaining patients on combined mood stabilizers--of which valproate is probably the most useful--and making judicious use of atypical neuroleptics. Benzodiazepines and alcohol (which produce withdrawal), caffeine, stimulants, exposure to bright light, and sleep deprivation during excited phases should be avoided. Thyroid and nimodipine augmentation can be considered in those with the most malignant course. These are patients who need the maximal support that their psychiatrist can provide them. Office visits must be arranged as the last appointment of the day.

Abstract
This article argues for the necessity of a partial return to Kraepelin's broad concept of manic-depressive illness, and proposes definitions--and provides prototypical cases--to illustrate the rich clinical phenomenology of bipolar subtypes I through IV. Although considerable evidence supports such extensions of bipolarity encroaching upon the territory of major depressive disorder, further research is needed in this area. From a practice standpoint, the compelling reason for broadening the bipolar spectrum lies in the utility of mood stabilizers as augmentation or monotherapy in the treatment of major depressive disorders with soft bipolar features falling short of the current strict standards for the diagnosis of bipolar II and hypomania in DSM-IV and ICD-10.
