Abstract

Folie a deux, or shared psychotic disorders, is an unusual psychiatric disorder in which delusional beliefs are transferred from one individual to one or more other susceptible persons in close connection. To date, it remains a rare, yet challenging psychiatric diagnosis. Here, we present a case report and discussion of folie a deux, involving two sisters.
