Pseudocyesis in organic mood disorders. Six cases

Pseudocyesis, the delusion of pregnancy, has had an uncertain nosology, primarily because of the concentration on the content of the beliefs and lack of interest in the underlying phenomenology. Six patients with a major mood disorder caused by cerebral dysfunction are presented in this article. The delusion is reviewed with respect to the entities it overlaps, and the clinical manifestations are related to the mood disorders. Although no clear neuroanatomic localization was possible with this group of patients, there may be some association with desomatization caused by parietal lobe dysfunction.
