The clinical features of postpartum psychoses.

The clinical features and symptoms of postpartum psychoses are presented in relation to the classification according to the Research Diagnostic Criteria (RDC) and the concept of "puerperal psychosis". A number of symptoms, ie confusional symptoms, depersonalization, misrecognitions and the "kaleidoscopic" picture are shown to be prominent features. In schizoaffective disorder and unspecified functional psychosis a higher frequency of confusional symptoms, misrecognitions, thematic delusions and a "kaleidoscopic" course of illness was found compared to schizophrenia, mania or depression. The findings of this study support a special status for postpartum psychosis and suggest a link with the concept of cycloid psychosis. In the management of postpartum mental disorder the risk of child-directed aggression, suicide and sudden relapses into psychosis requires special attention.
