Abstract
Objective: Bipolar disorder is highly comorbid with anxiety disorders, however current and lifetime comorbidity patterns of each anxiety disorder and their associated features are not well studied. Here, we aimed to conduct a meta-analysis and meta-regression study of current evidence. Method: We searched PubMed to access relevant articles published until September 2015, using the keywords "Bipolar disorder" or "Affective Psychosis" or "manic depressive" separately with "generalized anxiety," "panic disorder," "social phobia," "obsessive compulsive," and "anxiety." Variables for associated features and prevalence of anxiety disorders were carefully extracted. Results: Lifetime any anxiety disorder comorbidity in BD was 40.5%; panic disorder (PD) 18.1%, generalized anxiety disorder (GAD) 13.3%, social anxiety disorder (SAD) 13.5% and obsessive compulsive disorder (OCD) 9.7%. Current any anxiety disorder comorbidity in BD is 38.2%; GAD is 15.2%, PD 13.3%, SAD 11.7%, and OCD 9.9%. When studies reporting data about comorbidities in BDI or BDII were analyzed separately, lifetime any anxiety disorder comorbidity in BDI and BDII were 38% and 34%, PD was 15% and 15%, GAD was 14% and 16.6%, SAD was 8% and 13%, OCD was 8% and 10%, respectively. Current any DSM anxiety disorder comorbidity in BDI or BDII were 31% and 37%, PD was 9% and 13%, GAD was 8% and 12%, SAD was 7% and 11%, and OCD was 8% and 7%, respectively. The percentage of manic patients and age of onset of BD tended to have a significant impact on anxiety disorders. Percentage of BD I patients significantly decreased the prevalence of panic disorder and social anxiety disorder. A higher rate of substance use disorder was associated with greater BD-SAD comorbidity. History of psychotic features significantly affected current PD and GAD. Conclusions: Anxiety disorder comorbidity is high in BD with somewhat lower rates in BDI vs BDII. Age of onset, substance use disorders, and percentage of patients in a manic episode or with psychotic features influences anxiety disorder comorbidity.

Abstract
Both bipolar disorder and borderline personality disorder (BPD) are serious mental health disorders resulting in significant psychosocial morbidity, reduced health-related quality of life, and excess mortality. Yet research on BPD has received much less funding from the National Institute of Health (NIH) than has bipolar disorder during the past 25 years. Why hasn't the level of NIH research funding for BPD been commensurate with the level of psychosocial morbidity, mortality, and health expenditures associated with the disorder? In the present article, the author illustrates how the bipolar disorder research community has done a superior job of "marketing" their disorder. Studies of underdiagnosis, screening, diagnostic spectra, and economics are reviewed for both bipolar disorder and BPD. Researchers of bipolar disorder have conducted multiple studies highlighting the problem with underdiagnosis, developed and promoted several screening scales, published numerous studies of the operating characteristics of these screening measures, attempted to broaden the definition of bipolar disorder by advancing the concept of the bipolar spectrum, and repeatedly demonstrated the economic costs and public health significance of bipolar disorder. In contrast, researchers of BPD have almost completely ignored each of these four issues and research efforts. Although BPD is as frequent as (if not more frequent than) bipolar disorder, as impairing as (if not more impairing than) bipolar disorder, and as lethal as (if not more lethal than) bipolar disorder, it has received less than one-tenth the level of funding from the NIH and has been the focus of many fewer publications in the most prestigious psychiatric journals. The researchers of BPD should consider adopting the strategy taken by researchers of bipolar disorder before the diagnosis is eliminated in a future iteration of the DSM or the ICD.

Abstract
Compared with bipolar disorder, borderline personality disorder (BPD) is as frequent (if not more frequent), as impairing (if not more impairing), and as lethal (if not more lethal). Yet, BPD has received less than one-tenth the funding from the National Institutes of Health than has bipolar disorder. More than other reviewers of the literature on the interface between bipolar disorder and BPD, Paris and Black (Paris J and Black DW (2015) Borderline Personality Disorder and Bipolar Disorder: What is the Difference and Why Does it Matter? J Nerv Ment Dis 203:3-7) emphasize the clinical importance of correctly diagnosing BPD and not overdiagnosing bipolar disorder, with a focus on the clinical feature of affective instability and how the failure to recognize the distinction between sustained and transient mood perturbations can result in misdiagnosing patients with BPD as having bipolar disorder. The review by Paris and Black, then, is more of an advocacy for BPD than other reviews in this area have been. In the present article, the author will illustrate how the bipolar disorder research community has done a superior job of advocating for and "marketing" their disorder compared with researchers of BPD. Specifically, researchers of bipolar disorder have conducted multiple studies highlighting the problem with underdiagnosis, written commentaries about the problem with underdiagnosis, developed and promoted several screening scales to improve diagnostic recognition, published numerous studies of the operating characteristics of these screening measures, attempted to broaden the definition of bipolar disorder by advancing the concept of the bipolar spectrum, and repeatedly demonstrated the economic costs and public health significance of bipolar disorder. In contrast, researchers of BPD have almost completely ignored each of these issues and thus have been less successful in highlighting the public health significance of the disorder.

Abstract
Diagnostic confusion sometimes exists between bipolar disorder and borderline personality disorder (BPD). To improve the recognition of bipolar disorder researchers have identified nondiagnostic factors that point toward bipolar disorder. One such factor is the presence of a family history of bipolar disorder. In the current report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we compared the demographic, clinical, and psychosocial characteristics of patients with BPD who did and did not have a family history of bipolar disorder. A large sample of psychiatric outpatients were interviewed with semi-structured interviews. Three hundred seventeen patients without bipolar disorder were diagnosed with DSM-IV borderline personality disorder. Slightly less than 10% of the 317 patients with BPD (9.5%, n=30) reported a family history of bipolar disorder in their first-degree relatives. There were no differences between groups in any specific Axis I or Axis II disorder. The patients with a positive family history were significantly less likely to report excessive or inappropriate anger, but there was no difference in the frequency of other criteria for BPD such as affective instability, impulsivity, or suicidal behavior. The patients with a positive family history reported a significantly higher rate of increased appetite and fatigue. There was no difference in overall severity of depression, scores on the Global Assessment of Functioning, history of psychiatric hospitalizations, suicide attempts, time unemployed due to psychiatric reasons during the 5 years before the evaluation, and ratings of current and adolescent social functioning. There was no difference on any of the 5 subscales of the childhood trauma questionnaire. Overall, we found few differences between BPD patients with and without a family history of bipolar disorder thereby suggesting that a positive family history of bipolar disorder was not a useful marker for occult bipolar disorder in these patients.

Abstract
OBJECTIVE To determine the frequency with which bipolar II disorder (BD II) was diagnosed in clinics held in four rural towns in New South Wales (NSW). METHOD A retrospective case file audit was conducted for patients referred for psychiatric assessment and treatment in four towns in rural NSW over a period of two years and nine months. RESULTS Of 559 patients seen for the first time during the study period, 113 (20.2%) were diagnosed with BD II, and of these this diagnosis was made for the first time in 69 patients (61%). Associated clinical findings in BD II patients are presented and a comparison is made with patients with non-bipolar depression seen during the same period. CONCLUSION BD II was commonly seen in these rural clinics, and appears to be often under-diagnosed in general practice, as has been found to be the case in urban centres. This is seen as a serious public health problem, which needs to be addressed by educational steps directed at general practitioners (GPs), mental health clinicians, and perhaps also the general public.

Abstract
During the past 25 years, semistructured diagnostic interviews have been the standard for diagnostic evaluations in research relying on reliable and valid psychiatric assessment and diagnosis. However, the use of semistructured interviews still requires interpretation of the diagnostic criteria and does not preclude the application of different diagnostic thresholds. The goal of this report from the Rhode Island Methods to Improve Diagnostic Assessment and Services project is to illustrate how a self-report scale can be used to detect systematic differences in the application of diagnostic criteria for bipolar disorder and to demonstrate the wide variation in how broadly different groups tend to diagnose bipolar disorder. We compared the frequency of bipolar diagnoses in 4 studies that examined the performance of mood disorders questionnaire (MDQ) with the Structured Clinical Interview for DSM-IV (SCID). We also compared the prevalence rate of MDQ cases and the ratio of SCID diagnoses with MDQ cases. The frequency of bipolar disorder in the 4 studies ranged from 10.9% to 76.2%-a 7-fold difference in prevalence rates. The frequency of MDQ-positive cases ranged from 17.8% to 31.2%, less than a 2-fold difference in prevalence rates. Thus, there was much less variability in MDQ rates than diagnosis rates. Moreover, the rank order of the prevalence of MDQ cases differed from the rank order of the prevalence of SCID diagnoses. The SCID/MDQ ratio significantly differed between the studies. These findings demonstrate how systematic differences in diagnostic practice might be detected using a self-administered scale such as the MDQ. The results also underscore that wide variation exists in the bias toward diagnosing bipolar disorder, even after controlling for differences in prevalence among samples.

Abstract
OBJECTIVE Self-mutilation has traditionally been associated with borderline personality disorder, and seldom examined separately from suicide attempts. Clinical experience suggests that self-mutilation is common in bipolar disorder. METHODS A family study was conducted on the molecular genetics of depression and personality, in which the proband had been treated for depression. All probands and parents or siblings were interviewed with a structured interview and completed the Temperament and Character Inventory. RESULTS Fourteen per cent of subjects interviewed reported a history of self-mutilation, mostly by wrist cutting. Self-mutilation was more common in bipolar I disorder subjects then in any other diagnostic groups. In multiple logistic regression self-mutilation was predicted by mood disorder diagnosis and harm avoidance, but not by borderline personality disorder. Furthermore, the relatives of non-bipolar depressed probands with self-mutilation had higher rates of bipolar I or II disorder and higher rates of self-mutilation. Sixteen per cent of subjects reported suicide attempts and these were most common in those with bipolar I disorder and in those with borderline personality disorder. On multiple logistic regression, however, only mood disorder diagnosis and harm avoidance predicted suicide attempts. Suicide attempts, unlike self-mutilation, were not familial. CONCLUSIONS Self-mutilation and suicide attempts are only partially overlapping behaviours, although both are predicted by mood disorder diagnosis and harm avoidance. Self-mutilation has a particularly strong association with bipolar disorder. Clinicians need to think of bipolar disorder, not borderline personality disorder, when assessing an individual who has a history of self-mutilation.

Abstract
BACKGROUND The 9-repeat variable number tandem repeat allele of the dopamine transporter has recently been associated with borderline personality disorder (BPD) in depressed patients. METHODS We investigated the association between the 9-repeat allele of the dopamine transporter and angry-impulsive personality traits in a family study with 512 subjects on the molecular genetics of depression and personality. RESULTS Across the whole sample, the 9-repeat allele of the dopamine transporter was associated with angry-impulsive personality traits (p = .002). This association was stronger in subjects with no history of mood disorders or BPD (odds ratio [OR] = 4.85, p = .008) than in subjects with a history of mood disorders (OR = 1.73, p = .033). Angry-impulsive traits were also associated with lifetime mood disorder diagnoses and with BPD. CONCLUSIONS The associations reported in this article suggest that the 9-repeat allele of the dopamine transporter is associated with angry-impulsive personality traits, independent of any link to mood disorder or BPD. This could form the basis of a dopaminergic neurobiological model of angry-impulsive personality traits.

Abstract
To identify genes that may be relevant to the molecular action of antidepressants, we investigated transcriptional changes induced by the selective serotonin reuptake inhibitor paroxetine in a serotonergic cell line. We examined gene expression changes after acute treatment with paroxetine and sought to validate microarray results by quantitative PCR (qPCR). Concordant transcriptional changes were confirmed for 14 genes by qPCR and five of these, including the adrenomedullin gene (Adm), either approached or reached statistical significance. Reporter gene assays showed that a SNP (rs11042725) in the upstream flanking region of ADM significantly altered expression. Association analysis demonstrated rs11042725 to be significantly associated with response to paroxetine (odds ratio=0.075, P<0.001) but not with response to either fluoxetine or citalopram. Our results suggest that ADM is involved with the therapeutic efficacy of paroxetine, which may have pharmacogenetic utility.

Polymorphisms of sepiapterin reductase gene alter promoter activity and may influence risk of bipolar disorder. Pharmacogenet Genomics 2009; 19:330-7.

Abstract
OBJECTIVES In a previous investigation, we observed altered expression of sepiapterin reductase (SPR) in cultured neural cells chronically exposed to paroxetine. SPR is an enzyme, which catalyzes the final step in the synthesis of tetrahydrobiopterin (BH4). BH4 is an essential cofactor for synthesis of many neurotransmitters including serotonin. Given the pivotal role of SPR in neurotransmitter production, we sought to test the hypothesis that SPR would influence susceptibility to mood disorders and patient response to antidepressants. METHODS We tested for association of SPR promoter polymorphisms with antidepressant response in a well-characterized triad cohort of mood disorders. We evaluated the functional effect of these variants using the Dual-Luciferase Reporter Gene Assay System in two independent cell lines. RESULTS Two promoter single nucleotide polymorphisms (rs1876487 and rs2421095) in SPR were identified that occurred in three distinct haplotypes. We found a statistically significant association of haplotype pair 2,3 with bipolar I disorder [odds ratio: 5.47; 95% confidence interval: (1.68-17.88); P<0.005] and the personality measure self-transcendence (P = 0.020). Moreover, we found preliminary evidence that individuals with haplotype pair 2,3 responded better to the treatment with selective serotonin reuptake inhibitors. Reporter gene assays revealed a 1.4-fold to 1.6-fold decrease in the transcription rate of the two less common haplotypes (2 and 3) compared with haplotype 1, in the two cell lines investigated. CONCLUSION This reduced transcription rate for SPR promoter haplotypes 2 and 3 may impact on BH4-mediated neurotransmitter production, thus suggesting a biological process through which SPR gene variants might influence antidepressant response and susceptibility to bipolar disorder.

Abstract
Hes6 is a neurogenic gene which is down-regulated in the hippocampi of rats chronically treated with the antidepressant paroxetine. To assess whether variability in HES6 associates with mood disorder diagnosis or antidepressant response, this gene was sequenced in 24 unrelated New Zealand Caucasians. A total of 12 polymorphisms were identified, six of which were in the promoter region of the gene. Haplotypes encompassing the promoter SNPs were studied by cloning the region upstream of the transcription start site, and examining basal transcription rates in luciferase reporter gene assays. SNPs located at positions -1099, -831, -424 and -267 were shown to significantly alter expression of the reporter gene. These four variants were tested for association with mood disorder diagnosis or antidepressant response in a family study of depression, but no significant associations were observed. However, given the importance of this gene in neural function and development, the promoter variants described here may be of wider relevance.

Abstract
For any diagnostic system to be clinically useful, and go beyond description, it must provide an understanding that informs about aetiology and/or outcome. DSM-III and DSM-IV have provided reliability; the challenge for DSM-V and DSM-VI will be to provide validity. For DSM-V this will not be achieved. Believers in DSM-III and DSM-IV have impeded progress towards a valid classification system, so DSM-V needs to retain continuity with its predecessors to retain reliability and enhance research, but position itself to inform a valid diagnostic system by DSM-VI. This review examines the features of a diagnostic system and summarizes what is really known about mood disorders. The review also questions whether what are called mood disorders are primarily disorders of mood. Finally, it provides suggestions for DSM-VI.

A relationship between bipolar II disorder and borderline personality disorder? Prog Neuropsychopharmacol Biol Psychiatry 2008; 32:1022-9.

Abstract
BACKGROUND The relationship between DSM-IV-TR borderline personality disorder (BPD) and bipolar disorders, especially bipolar II disorder (BP-II), is still unclear. Many recent reviews on this topic have come to opposite or different conclusions. STUDY AIM The aim was to test the association between hypomania symptoms and BPD traits, as hypomania is the defining feature of BP-II in DSM-IV-TR. METHODS During follow-up visits in a private practice, consecutive 138 remitted BP-II outpatients were re-diagnosed by a mood disorder specialist psychiatrist, using the Structured Clinical Interview for DSM-IV (as modified by Benazzi and Akiskal for better probing hypomania). Soon after, patients self-assessed (blind to interviewer) the SCID-II Personality Questionnaire for BPD. Associations and confounding were tested by logistic regression, between each criteria symptom of hypomania (apart from "racing thoughts" and "distractibility", not assessed as probing focused mainly on behavioral, observable signs), and the entire set of BPD traits. Multivariate regression was also used to jointly regress the entire set of hypomanic symptoms on the entire set of BPD traits. RESULTS Mean (SD) age was 39.0 (9.8) years, females were 76.3%. Frequency of BPD traits ranged between 17% and 66% (e.g. impulsivity trait 41%, affective instability trait 63%), mean (SD) number of traits was 4.2 (2.3). The most common episodic hypomanic symptoms were elevated mood (91%) and overactivity (93%); frequency of excessive risky, impulsive activities (impulsivity) was 62%. By logistic regression the only significant association was between the episodic impulsivity of hypomania and the trait impulsivity of BPD. Multivariate regression of the entire set of hypomanic symptoms jointly regressed on the entire set of BPD traits was not statistically significant. DISCUSSION The core feature of BP-II, i.e. hypomania, does not seem to have a close relationship with BDP traits in the study setting, partly running against a strong association between BPD and BP-II and a bipolar spectrum nature of BPD.
