Other functional psychoses

Research effort in schizoaffective disorder and other functional psychoses remains directed at refining phenomenologic descriptions of these conditions. Several outcome studies provide new information on the natural course of schizoaffective disorder. Other studies provide clinical descriptions of postpartum psychosis in the developing world, and also of primary erotomania and late-onset psychosis. Leukoencephalopathy, as recorded by magnetic resonance imaging is reported as a pervasive feature of late-onset psychosis. Finally, the putative relationship between the reproductive hormones and brain dopamine is addressed in a series of case reports on postpartum psychosis.
