Functional impairment in bipolar II disorder: Is it as disabling as bipolar I?

It is well established that patients with bipolar disorder experience functional impairment even in remission. Nevertheless, bipolar II disorder remains understudied because most investigations to date include only bipolar I patients or just a small sample of bipolar II patients, without explicitly comparing both subtypes of disorder. The main objective of the current report is to evaluate overall and multiple domains of functioning, specifically in bipolar II disorder compared to patients with bipolar I disorder and healthy subjects.233 subjects from 3 groups were compared: bipolar I patients (n=106), bipolar II patients (n=66) and healthy controls (n=61). Bipolar patients meeting criteria…

The potential use of biomarkers as an adjunctive tool for staging bipolar disorder

Recent data show that biomarkers differ in early and late-stage bipolar disorder (BD). Here we propose a model of staging for bipolar disorder that emphasizes the potential use of biomarkers for differentiating early and late-stage BD patients in the inter-episodic period. The proposed model includes a Latent phase: patients at "ultra-high-risk" for developing BD, characterized by a family history of BD, temperament traits, mood, and anxiety symptoms as well as genetic vulnerability for developing the disorder; Stage I: patients who return to their baseline level of functioning when mood episodes resolve; Stage II: biomarkers and functioning impairment are related to comorbidities or rapid-…

Screening for bipolar disorders in Spanish-speaking populations: sensitivity and specificity of the Bipolar Spectrum Diagnostic Scale-Spanish Version.

Background: Bipolar disorder is commonly misdiagnosed, perhaps more so in Latin American and Spanish-speaking populations than in the United States. The Bipolar Spectrum Diagnostic Scale (BSDS) is a 19-item screening instrument designed to assist in screening for all types of bipolar disorder. Methods: The authors investigated the sensitivity of a Spanish-language version of the BSDS in a cohort of 65 outpatients with a diagnosis of bipolar disorder, based on a semi-structured interview and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. To determine specificity, we assessed a control group of 36 outpatients with diagnosis of unipolar major dep…

Antecedents of manic versus other first psychotic episodes in 263 bipolar I disorder patients.

Objective As initial episode type can predict later morbidity in bipolar disorder, we tested the hypothesis that clinical antecedents might predict initial episode types. Method We studied 263 first-episode, adult, DSM-IV-TR type I bipolar disorder (BD-I) subjects within the McLean-Harvard-International First-Episode Project. Based on blinded assessments of antecedents from SCID examinations and clinical records, we compared first lifetime manic vs. other (mixed, depressive, or non-affective) major psychotic episodes. Results We identified 32 antecedents arising at early, intermediate or later times, starting 12.3 ± 10.7 years prior to first lifetime major psychotic episodes. Based on multi…

Predominant polarity and temperament in bipolar and unipolar affective disorders.

Abstract Introduction Recently, the concept of predominant polarity (two-thirds of episodes belonging to a single pole of the illness) has been introduced to further characterise subtypes of bipolar disorders. This concept has been proven to have diagnostic and therapeutic implications, but little is known on the underlying psychopathology and temperaments. With this study, we aimed to further validate the concept and explore its relationships with temperament. Methods This study enrolled 143 patients with bipolar or unipolar disorder. We analysed predominant polarity in the sample of bipolar I patients (N = 124), focussing on those who showed a clear predominance for one or the other polar…

Autobiographical memories are deeply linked with emotional regulation processes and self-concept. Conversely, in case of affective disorders, the access to specific phenomenological components would be impaired. Intentional non-probabilistic sampling was carried out, involving 94 individuals with major depression and 188 healthy individuals in the city of Buenos Aires, Argentina. The phenomenological components of significant autobiographical recollections were contrasted, considering their quantity and intensity. In addition, the depressive individuals' performances were compared according to the presence or absence of previous depressive episodes, psychopharmacological treatment and sever…

Pharmacotherapy in bipolar disorders during hospitalization and at discharge predicts clinical and psychosocial functioning at follow-up

Objective Individuals with bipolar disorder (BD) usually report significant disability and psychosocial impairment. Both the nature and causes associated with this impairment are poorly understood. In particular, research examining the impact of pharmacotherapy on the different aspects of psychosocial functioning in bipolar patients is currently lacking. The aim of this study was to assess to what extent the psychotropic medications used during psychiatric hospitalization and at discharge can predict clinical psychosocial functioning and the severity of the illness at follow-up in inpatients with bipolar disorder (BD). Methods Patients were 71 adult BD patients contacted on average 31 month…

The impact of psychopharmacology on contemporary clinical psychiatry.

Clinical psychiatric evaluations of patients have changed dramatically in recent decades. Both initial assessments and follow-up visits have become brief and superficial, focused on searching for categorical diagnostic criteria from checklists, with limited inquiry into patient-reported symptomatic status and tolerability of treatments. The virtually exclusive therapeutic task has become selecting a plausible psychotropic, usually based on expert consensus guidelines. These guidelines and practice patterns rest mainly on published monotherapy trials that may or may not be applicable to particular patients but are having a profound impact, not only on modern psychiatric practice but also on…

Recurrence rates in bipolar disorder: Systematic comparison of long-term prospective, naturalistic studies versus randomized controlled trials

Bipolar disorder (BD) is a recurrent, lifelong illness with high risks of disability and excess mortality. Despite many treatment options with demonstrated short-term efficacy, evidence concerning long-term treatment effectiveness in BD remains limited and the relative value of naturalistic studies versus randomized, controlled trials (RCTs) in its assessment, uncertain. Systematic computer-searching yielded 10 naturalistic studies and 15 RCTs suitable for analysis of recurrence rates and their association with treatments and selected clinical factors. In naturalistic studies (3904 BD subjects, 53.3% women, 85.8% BD-I, mean onset age 29.1, followed up to 2.1 years), the pooled recurrence ra…

Level of response and safety of pharmacological monotherapy in the treatment of acute bipolar I disorder phases: a systematic review and meta-analysis.

In recent years, combinations of pharmacological treatments have become common for the treatment of bipolar disorder type I (BP I); however, this practice is usually not evidence-based and rarely considers monotherapy drug regimen (MDR) as an option in the treatment of acute phases of BP I. Therefore, we evaluated comparative data of commonly prescribed MDRs for both manic and depressive phases of BP I. Medline, PsycINFO, EMBASE, the Cochrane Library, the ClinicalStudyResults.org and other data sources were searched from 1949 to March 2009 for placebo and active controlled randomized clinical trials (RCTs). Risk ratios (RRs) for response, remission, and discontinuation rates due to adverse …
