Bipolar II disorder is associated with thinning of prefrontal and temporal cortices involved in affect regulation

Abstract

These results indicate that BD-II is associated with thinning of prefrontal and temporal cortices implicated in the expression and regulation of negative and positive affect. Longitudinal studies are needed to clarify whether cortical thinning is a stable trait of BD-II, an illness effect that might progress during the course of the disease, or a combination of the two.
