Objective: To examine magnetic resonance imaging (MRI) characteristics in children and adolescents with mania according to DSM-III-R criteria.
Method: A convenience sample of consecutively referred 8- to 16-year-old manic (n = 10) and normal (n = 5) subjects were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present Episode Version, the Children's Global Assessment Scale, and the Family History-Research Diagnostic Criteria. MRI scans were obtained from unsedated subjects using a 1.5 T MR scanner to acquire T1-weighted coronal and sagittal images and T2-weighted axial images. Images were assessed by blind clinical interpretation, ratings of T2-weighted deep white matter hyperintensities and petalia, and computer-assisted volumetric analysis of ventricular and cerebral volumes.
Results: Eight of 10 manic subjects and all 5 controls completed the scans. Scans of 4 manic subjects and 1 control subject showed ventricular or white matter abnormalities by clinical interpretation. Significant findings were positive correlations between increasing age and both right and left ventricular volumes. Two of the 8 manic subjects and no controls had confluent subcortical hyperintensities.
Conclusions: MRI brain scanning was feasible in 8- to 16-year-olds. Preliminary findings from clinical interpretations and structured ratings suggest structural differences between young manic and normal subjects. Investigations of larger samples are needed to better characterize the differences.

Patients with schizophrenia often find themselves in vulnerable situations because their cognitive impairments can make them more susceptible to exploitation and crime. A prevalent misconception is that schizophrenia is synonymous with violence, possibly fueled by selective media coverage that highlights instances of violent crimes involving individuals with schizophrenia. In reality, a large percentage of people with schizophrenia do not display violent behavior.

Background: Voice analysis has emerged as a potential biomarker for mood state detection and monitoring in bipolar disorder (BD). The systematic review aimed to summarize the evidence for voice analysis applications in BD, examining (1) the predictive validity of voice quality outcomes for mood state detection, and (2) the correlation between voice parameters and clinical symptom scales.
Methods: A PubMed, Scopus, and Cochrane Library search was carried out by two investigators for publications investigating voice quality in BD according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statements.

Objective: A proportion of patients with bipolar disorder (BD) manifests with only Unipolar mania (UM). We conducted a follow-up study of patients diagnosed with Unipolar mania and compared them as a group if they had a mild depressive episode with those who did not.
Method: 248 subjects were prospectively followed-up to 15 years.

Mitochondria are organelles involved in different cellular functions, especially energy production. A relationship between mitochondrial dysfunction and mood disorders, especially bipolar disorder (BD), has been reported in the scientific literature, which suggests altered energy production and higher levels of oxidative stress compared to healthy controls. Specifically, in BD, the hypothesis of a biphasic pattern of energy availability has been postulated according to mood states.

Electroconvulsive therapy (ECT) is widely recognized as a safe and effective intervention for treating severe affective episodes in patients with bipolar disorder. However, it can sometimes precipitate unexpected manic phases in patients treated for a depressive episode, a phenomenon known as ECT-induced mania. While this occurrence is recognized, it remains poorly understood and minimally addressed in the literature.
