Efficacy of quetiapine XR vs. placebo as concomitant treatment to mood stabilizers in the control of subthreshold symptoms of bipolar disorder: Results from a pilot, randomized controlled trial.
Patients with bipolar disorder (BD) do not always achieve full remission between episodes. Subthreshold symptoms (depressive, manic or mixed) represent a major cause of relapse and disability in these patients. Immediate release (IR) and extended release (XR) formulations of quetiapine are both indicated for short and long-term treatment of BD. The aim of this study was to evaluate the efficacy of quetiapine XR vs placebo in subthreshold symptomatology when added to previous mood stabilizer treatment. A pilot phase IIIB, multicentre, prospective, placebo controlled, randomized, double blinded study of 12 weeks follow-up was performed (NCT01197846). Patients were randomized to quetiapine XR …
Functional remediation for patients with bipolar II disorder: improvement of functioning and subsyndromal symptoms.
Recently, Functional Remediation (FR) has proven to be effective in improving the functional outcome of euthymic bipolar patients. The aim of this study was to test the efficacy of the FR program in a subsample of euthymic bipolar II patients (BPII). A post-hoc analyses were undertaken using data of 53 BPII outpatients who had participated in a multicenter, rater-blind, randomized, controlled trial exploring the efficacy of FR (n=17) as compared with a Psychoeducation group (PSY) (n=19) and a treatment as usual control group (TAU n=17). The primary outcome variable was the functional improvement defined as the mean change in the Functioning Assessment Short Test (FAST) from baseline to endp…
Effects of atypical antipsychotics on neurocognition in euthymic bipolar patients

Factors associated with poor functional outcome in bipolar disorder: sociodemographic, clinical, and neurocognitive variables.
Objective: The current investigation aimed at studying the sociodemographic, clinical, and neuropsychological variables related to functional outcome in a sample of euthymic patients with bipolar disorder(BD) presenting moderate-severe levels of functional impairment. Methods: Two-hundred and thirty-nine participants with BD disorders and with Functioning Assessment Short Test(FAST) scores equal or above 18 were administered a clinical and diagnostic interview, and the administration of mood measure scales and a comprehensive neuropsychological battery. Analyses involved preliminary Pearson bivariate correlations to identify sociodemographic and clinical variables associated with the FAST t…
Effects of functional remediation on neurocognitively impaired bipolar patients: enhancement of verbal memory
BackgroundFunctional remediation is a novel intervention with demonstrated efficacy at improving functional outcome in euthymic bipolar patients. However, in a previous trial no significant changes in neurocognitive measures were detected. The objective of the present analysis was to test the efficacy of this therapy in the enhancement of neuropsychological functions in a subgroup of neurocognitively impaired bipolar patients.MethodA total of 188 out of 239 DSM-IV euthymic bipolar patients performing below two standard deviations from the mean of normative data in any neurocognitive test were included in this subanalysis. Repeated-measures analyses of variance were conducted to assess the i…
EPA-0492 - Functional remediation in bipolar II patients: improvement of functioning and subsyndromal symptoms
Introduction Recently, Functional Remediation (FR) has proven to be effective in improving the functional outcome of euthymic bipolar patients. Objective Our objective was to test the efficacy of FR programme in a subsample of euthymic bipolar II patients (BPII). Aims The main aim was improve the functional outcome in these patients. Method Post-hoc analyses were undertaken using data of 53 DSM-IV diagnosed BPII outpatients who had participated in a multicentre, rater blind, randomized, controlled trial (RCT) exploring the efficacy of FR (n=17) as compared with a Psychoeducation (PSY) (n=19) and a control (n=17) groups which only treatment as usual (TAU). The primary outcome variable was a …
Do patients with bipolar disorder and subsyndromal symptoms benefit from functional remediation? A 12-month follow-up study
We analyzed the efficacy of functional remediation, in a sample of patients with bipolar disorder who presented with subsyndromal symptoms. From a total sample of 239 patients with bipolar I and II disorder, according to DSM-IV-TR diagnostic criteria, entering a randomized clinical trial, those patients who presented with subsyndromal symptoms were selected based on a method already described by Berk and colleagues was applied. It consists of using the Clinical Global Impression-Bipolar version (CGI-BP) to establish the scores of the Hamilton Depression Rating Scale (HAM-D) and of the Young Mania Rating Scale (YMRS) that correspond with 1 in the CGI-BP. Functional outcome and mood symptoms …
Effects of atypical antipsychotics on neurocognition in euthymic bipolar patients.
Abstract Background Different factors may influence cognitive functioning in bipolar disorder such as the effect of subsyndromal symptoms, the history of psychotic symptomatology or substance abuse, negative symptomatology, chronicity, sleep disturbances, and hormonal factors. The effect of pharmacologic treatment on cognition is still uncertain because of an insufficient number of studies examining this issue. Objective The aims of this study were to compare neuropsychologic performance of treated bipolar patients with that of controls, including unmedicated patients and healthy subjects, as well as to evaluate possible neurocognitive differences among 3 different atypical antipsychotics. …
Cognitive impairment in schizoaffective disorder: a comparison with non-psychotic bipolar and healthy subjects.
Objective: Only a few studies have examined specifically the neuropsychological performance of schizoaffective patients. Method: The sample consisted of 34 euthymic DSM-IV schizoaffective patients, who were compared with 41 euthymic bipolar patients without history of psychotic symptoms and 35 healthy controls. Euthymia was defined by a score of 6 or less at the Young Mania Rating Scale and a score of 8 or less at the Hamilton Depression Rating Scale for at least 6 months. Patients were compared with several clinical, occupational, and neuropsychological variables such as executive function, attention, verbal and visual memory and the two groups were contrasted with 35 healthy controls on…
