TL;DR: The largest study to date of cortical gray matter thickness and surface area measures from brain magnetic resonance imaging scans of bipolar disorder patients is performed, revealing previously undetected associations and providing an extensive analysis of potential confounding variables in neuroimaging studies of BD.

TL;DR: Investigation of the relationship between GM volumes and age specifically during non-elderly life in 89 healthy individuals found that age-related dorsolateral prefrontal volume decrements followed non-linear patterns, and were less prominent in females compared to males at this age range.

TL;DR: The findings suggest that brain changes associated with the diagnosis of schizophrenia are more widespread in chronic schizophrenia compared to first-episode patients, and suggest that relative GM volume deficits may be greater in (presumably more severe) cases with earlier age of onset, as well as varying as a function of illness duration in specific frontal brain regions.

TL;DR: Structural abnormalities reported in psychosis in high-income countries are also present in first-episode psychosis in Brazil, and a similar pattern of decrease in grey matter relative to controls is exhibited.

TL;DR: Significant cognitive deficits are found in patients investigated early during the course of psychotic disorders in an environment that is distinct from those where the subjects investigated in previous studies have been drawn from.
