  1. Folie à deux

    Folie à deux, or shared psychosis, is a psychiatric syndrome in which symptoms of a delusional belief are transmitted from one individual to another. The same syndrome shared by more than two people may be called folie à trois, folie à quatre, folie en famille or even folie à plusieurs. Recent psychiatric classifications refer to the syndrome as shared psychotic disorder and induced delusional disorder in the ICD-10, although the research literature largely uses the original name. The disorder was first conceptualized in 19th century French psychiatry by Charles Lasègue and Jean-Pierre Falret and so also known as Lasègue-Falret Syndrome.
