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

Case Report

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.

Key words

Capgras delusion Familiar People Processing Reduplicative misidentification Degenerative dementia 

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.
