Abstract:
Objective. The authors report a case during which they observed serious subtypes of induced delusional psychosis (folie communiquée and folie simultanée) without any common genetic background or premorbid psychosis in the case of the secondary patient. Method. The clinical phenomenology of the case is described. Results. Mild intellectual disability and environmental-psychological factors (social isolation and the symbiotic-like interpersonal relatedness) play an essential aetiological role in the case of the secondary recipient patient. Conclusion. The authors emphasize the importance of subclassification of induced delusional psychosis for further aetiological and clinical research.
