The case of lost Wilma: a clinical report of Capgras delusion

Abstract

This detailed clinical report of a typical Capgras delusion (CD) in a demented patient is presented in order to foster future descriptions in neurological cases. In the framework of a recently developed model of familiar person processing, it is suggested that CD might be due to a dysfunction at the level of Person Identity Nodes. Prefrontal impairment is held to represent a critical factor leading to a failure of belief evaluation.

Sommario

Viene presentata la descrizione dettagliata di un caso di sindrome di Capgras in un paziente affetto da demenza allo scopo di evidenziarne gli aspetti clinici e comportamentali più rilevanti ai fini delle future descrizioni di simili casi neurologici. Facendo riferimento ai modelli cognitivi relativi al riconoscimento e identificazione di persone familiari, si propone che la sindrome di Capgras sia conseguente a un danno a livello dei Person Identity Nodes. Si ipotizza inoltre un deficit prefrontale come fattore critico per determinare l’incapacità di rifiutare come assurda la reduplicazione.
