Pseudocyesis Leading to Folie-à-Deux

Abstract Pseudocyesis or false belief of pregnancy is the emergence of classical manifestations of pregnancy—nausea, breast enlargement and pigmentation, abdominal distention, amenorrhea, and labor pains—in a nonpregnant woman. It is a multifactorial disease and its development is influenced by many different elements such as neuroendocrine, social, psychodynamic, and cultural issues. “Folie-à-deux,” is shared psychotic disorder, describes a syndrome in which delusion is transferred to another person who is more susceptible. Both individuals are closely related or know each other for a long time and typically live together in relative social isolation. In its commonest form, the individual who first develops the delusion (the primary case) is often chronically ill and typically is the dominant member in a close relationship with a more suggestible person (the secondary case) who also develops the delusion. Treatment options should also be kept in mind as antipsychotics themselves can increase prolactin levels and can lead to amenorrhoea and galactorrhea and can further strengthen patient’s belief about her pregnancy. This case highlights that the most important therapeutic step in the treatment of folie-à-deux is separation of the inducer and the induced. Here we describe a case of folie-à-deux of a married couple in which the female had delusional pregnancy while the husband shared and supported her delusion against substantial medical evidence.
