This chapter explores the phenomenon of folie a deux, which can occur in several syndromes in which mental symptoms, particularly paranoid delusions, are transmitted from one person to one or more others with whom the apparent instigator is in some way intimately associated, so that they also come to share the same delusional ideas. The epidemiology, psychopathology, & treatment of this condition is explored, & its association with suicide pacts is briefly discussed. (65 refs)
