Background: Emotion processing deficits have been described in patients with bipolar disorder (BD) and are considered one of the core cognitive abnormalities in BD with endophenotype potential. However, the literature on specific impairments in emotion processing cognitive strategies (directive/cortical/higher versus intuitive/limbic/lower) in euthymic adult BD patients and healthy first-degree relatives/high-risk (HR) subjects in comparison with healthy controls (HCs) is sparse.

Methods: We examined facial emotion recognition deficits (FERD) in BD (N = 30), HR (N = 21), and HC (N = 30) matched for age (years), years of education, and sex using computer-administered face emotions–Matching And Labeling …

Clozapine For Treatment-Resistant Bipolar Disorder: A Systematic Review, Xian-Bin Li, Yi-Lang Tang, Chuan-Yue Wang, Jose De Leon

Psychiatry Faculty Publications

Objective

To evaluate the efficacy and safety of clozapine for treatment-resistant bipolar disorder (TRBD).

Methods

A systematic review of randomized controlled studies, open-label prospective studies, and retrospective studies of patients with TRBD was carried out. Interventions included clozapine monotherapy or clozapine combined with other medications. Outcome measures were efficacy and adverse drug reactions (ADRs).

Results

Fifteen clinical trials with a total sample of 1,044 patients met the inclusion criteria. Clozapine monotherapy or clozapine combined with other treatments for TRBD was associated with improvement in: (i) symptoms of mania, depression, rapid cycling, and psychotic symptoms, with many patients with TRBD achieving …

Interactions Between Antiepileptics And Second-Generation Antipsychotics, Jose De Leon, Vincenza Santoro, Concetta D'Arrigo, Edoardo Spina

Psychiatry Faculty Publications

INTRODUCTION: Pharmacokinetic and pharmacodynamic drug interactions (DIs) can occur between antiepileptics (AEDs) and second-generation antipsychotics (SGAPs). Some AED and SGAP pharmacodynamic mechanisms are poorly understood. AED-SGAP combinations are used for treating comorbid illnesses or increasing efficacy, particularly in bipolar disorder.

AREAS COVERED: This article provides a comprehensive review of the interactions between antiepileptics and second-generation antipsychotics. The authors cover pharmacokinetic AED-SGAP DI studies, the newest drug pharmacokinetics in addition to the limited pharmacodynamic DI studies.

EXPERT OPINION: Dosing correction factors and measuring SGAP levels can help to compensate for the inductive properties of carbamazepine, phenytoin, phenobarbital and primidone. Further studies …

No prospective studies of first psychotic episodes have explored sex differences in smoking cessation. The aim of this study was to determine the influence of sex and substance abuse on smoking cessation during an 8-year follow-up of patients after a first psychotic episode. Logistic regression modeling was used to identify factors associated with smoking cessation by sex. To examine for sex variable interactions, the following two methods were used: 1) for other clinical variables, mixed analyses were calculated; and 2) for use of other substances, logistic regression models were performed only in the substance users. At baseline, 79% of men …
