Pseudocyesis preceding psychosis.

Pseudocyesis is an uncommon condition in which the psychological and somatic phenomena are usually thought to arise with neurotic rather than psychotic illness. We report a patient whose pseudocyesis took a course not previously described, culminating in an acute schizophrenic episode. Despite this she demonstrated many similarities with neurotic patients previously described in the literature. A phenomenological explanation, the belief of pregnancy as an overvalued idea, is discussed.
