Folie à Deux, also known as shared psychosis, is a is a psychotic disorder uncommon characterized by the shared manifestation of delusional beliefs between two individuals or more. The individual who initially experiences these delusional thoughts is referred to as the primary case, while the subsequent transmission of these beliefs to another person designates them as the secondary case. Typically, this phenomenon arises within close interpersonal relationships, such as familial or intimate partnerships. The primary case is typically diagnosed with a psychotic disorder, while the secondary case, lacking any previous psychiatric history, develops similar delusions as a consequence of close contact with the primary case. It is important to note that the specific shared delusional beliefs can exhibit considerable variability, contingent upon the nature of the primary case's delusions and their influence on the secondary case. Common types of shared delusions encompass persecutory, grandiose, erotomanic, somatic, jealous, and religious misbeliefs. Moreover, it is imperative to recognize that the particular delusional content observed in cases of Folie à Deux can be subject to significant variation, potentially influenced by cultural, interpersonal, and environmental factors.
