title: [Psychopathological concepts of induced insanity exemplified by folie a deux].
abstract: We report on a case of a "folie à deux" between sister and brother (56 and 61 years of age). Based on a definition of the concept of the induced psychoses, we focus attention on some special aspects of these double psychoses. Special consideration is given to psychopathological constellations and their meaning, with etiogenetic aspects of "process" and "development" with regard to the concept of vulnerability. We could show that in such cases the new operationalised diagnostic manuals like DSM-IV and ICD-10 are based on traditional concepts.
