Shared Psychotic Disorder, also known as Folie à Deux, is a rare psychiatric condition characterized by the transmission of delusional beliefs from one individual, referred to as the primary or the inducer, to another person, known as the secondary or the recipient. In this disorder, the secondary individual develops delusions that are similar to those of the primary person.
The delusions in Shared Psychotic Disorder are usually induced when the secondary individual has a close relationship with the primary person, such as family members or partners living in close proximity. The process of transmission of delusions often occurs through intense and prolonged interaction, resulting in the secondary person internalizing the delusional beliefs of the primary person. However, in some cases, the secondary person may also develop their own unique delusions that are influenced by the primary person's psychotic symptoms.
Symptoms of Shared Psychotic Disorder may include irrational beliefs, hallucinations, and distorted perceptions of reality. The content of the delusions is heavily influenced by the primary person's delusions and can be bizarre or outlandish. The secondary person, under the influence of the shared delusion, may begin to exhibit behaviors consistent with the delusional beliefs, further reinforcing the shared psychosis.
Treatment for Shared Psychotic Disorder typically involves separating the primary and secondary individuals to reduce the influence of the delusions. Psychotherapy, particularly individual therapy, may be beneficial in helping the secondary person regain a sense of reality and autonomy. Medication, such as antipsychotics, may also be prescribed to alleviate symptoms and stabilize the affected individuals. With appropriate treatment and support, many individuals with Shared Psychotic Disorder can recover and regain their mental well-being.
