Socio-Clinical Substrates of Folie à Deux

Abstract

Folie à deux, the psychosis of association, has been defined as ‘the transference of delusional ideas and/or abnormal behaviour from one person to one or more individuals who have been in close association with the primary affected person’ (8). At least three conditions have been regarded as pre-requisite for its diagnosis: (a) definite evidence that the partners have been intimately associated, (b) identical content of the delusional ideas in both the patients, and (c) unequivocal evidence that the partners share, support and accept each other's delusions (7).
