Abstract

An elderly woman developed the delusion that she was dead ('Cotard's delusion') and that she was in another place ('reduplicative paramnesia'). Charles Bonnet reported this unique combination of symptoms a century before Cotard's influential description of the nihilistic delusions and of Pick's description of 'reduplicative paramnesia'.
