Treatment nonadherence is a leading cause of poor outcomes among populations with bipolar disorder (BD) and is related to subjective experience of illness and treatment. This study examined gender differences in the experience of illness and treatment for those with BD, specifically in regards to treatment adherence. This cross-sectional analysis pooled data from 3 BD studies. A semistructured qualitative instrument, the Subjective Experience of Medication Interview, elicited information on subjective differences in treatment adherence between men and women. Men and women experience comparable levels of stigma and they comparably value lessened irritability and/or impulsivity because of medications. However, men and women differed in fear of weight gain because of medications, value of social support, and self-medication behaviors. Selected differences in subjective illness experience between men and women might be used to inform gender-sensitive approaches to enhance treatment adherence among populations with BD

Bifrontal (BF) electroconvulsive therapy (ECT), although researched less extensively than bitemporal (BT) or right unilateral (RUL) ECT, has been suggested to be comparable to the other 2 electrode placements with respect to clinical efficacy while resulting in less cognitive impairment than BT ECT. Imaging studies have indicated that seizures induced by BF ECT affect the brain differently than BT or RUL ECT, in that BF ECT increases cerebral blood flow in the frontal lobes more intensely than either of the other 2 placements. Therefore, it is possible that the cognitive impairment manifested after a course of BF ECT could also be different than the impairment seen with BT and RUL ECT. Research conducted on cognitive impairment from BF ECT to date has been inadequate due to the use of nonspecific cognitive measures (such as the Mini-Mental Status Examination) or an inordinate focus on memory functioning (which is believed to be mostly subsumed in the temporal lobes). Because BF ECT increases cerebral blood flow in the frontal lobes more intensely than either of the other placements, research must instead focus on investigating the possible effects of BF ECT on executive functioning, which is believed to be subsumed in the frontal lobes. This is especially important because of the established relationship between executive dysfunction and depression and also because of the increasing popularity of BF ECT

INTRODUCTION: Mitochondria are intracellular organelles involved in adenosine triphosphate production. The literature has established the presence of mitochondrial dysfunction in some subjects with psychiatric disorders. Also, there are multiple reports of patients with mitochondrial dysfunction who have various psychiatric disorders. Although the literature on mitochondrial dysfunction and its relation to psychiatric disorders is growing, there remain many unanswered questions. OBJECTIVE: To review subjects with mitochondrial cytopathies for prevalence of psychiatric comorbidity. METHODS: For this study, 36 adults were interviewed. The Mini International Neuropsychiatric Interview and the Short-Form 36 Health Survey, version 1 were used. RESULTS: Lifetime diagnoses included 54% major depressive disorder, 17% bipolar disorder, and 11% panic disorder. These prevalence rates are compared with the general population and subjects with cancer and epilepsy. Subjects with a comorbid psychiatric diagnosis were older (P=.05), had more hospital admissions (P=.02), more medical conditions (P=.01), and lower quality of life (P=.01) than subjects with mitochondrial disease alone. CONCLUSION: Clinicians caring for persons with mitochondrial cytopathies should note the high prevalence of psychiatric problems. Also, this comorbidity might have etiological and therapeutic implications

The psychiatric effects of anabolic-androgenic steroids (i.e., testosterone and its derivatives) have been less well studied than their physical effects but are reported to include depression, mania, psychosis, and aggression. Dependence can also occur, with withdrawal involving psychiatric and physical symptoms. Adverse effects of steroid abuse should be managed by discontinuing the drugs-by tapering if necessary-and by treating the symptoms

Mitochondria are intracellular organelles crucial to the production cellular energy. Mitochondrial disease results from a malfunction in this biochemical cascade. These disorders can affect any organ system, producing diverse signs and symptoms, including psychiatric ones. Several authors argue that mitochondrial dysfunction is related to the pathophysiology of bipolar disorder and schizophrenia. Also, the authors retrieved 19 case reports that describe patients with mitochondrial diseases and psychiatric disorders. Most of these patients have psychiatric presentations that preceded the diagnosis of mitochondrial disease. The most common physical findings are fatigue, muscle weakness with or without atrophy, and hearing loss
