A case report of folie a deux: Mother and daughter

Shared paranoid disorders, a relatively rare psychiatric disorder in which paranoid delusions are transferred from one individual to one or more other susceptible person(s) in close association. Folie a deux is characterized by a complex dependent relationship between the involved individuals, yet a challenging diagnosis. In the paradigm of changing nosology, where the term shared/induced psychotic disorder is going obsolete, it is important to recognize such cases due to the potential for recovery in the submissive partner. Here, we present a case report and discussion of folie a deux involving inducer mother and induced daughter. In the clinical case presented, folie a deux was easily diagnosed, but its treatment proved to be a bigger challenge.
