Délires de reduplication mnésique : connaissance de soi et perplexité identitaire

Abstract

RésuméObjectif : Une incohérence du sentiment de Soi ou Self ne procède pas toujours d'un déficit de la mémoire autobiographique. Conclusion : L'altération du sentiment de Soi peut ainsi procéder non d'un déficit de la mémoire mais de la difficulté qu'a un sujet à intégrer à sa mémoire (identité narrative) un souvenir imaginaire dont la réalité s'impose néanmoins à lui.Mots clés : Connaissance de Soi ; Identité ; Mémoire AbstractObjective: An inconsistency in the sense of self does not necessarily follow from a deficit of autobiographical memory. Materials and methods:We report two cases of memory reduplication with delusion, one concerning an event reduplication memory, the other one a spatial reduplication memory.Results: The first patient, J.M., presents with a confusion of identity, which forces him to search for some evidence in his imaginary memory. The second patient, R.B., remembered having juxtaposed two separate geographical sites, became aware of his false conviction, and Page 2 of 2 A c c e p t e d M a n u s c r i p t finally attempted to find explanations for this perceptual illusion.Conclusion: Impairment of self-knowledge can be caused not only by a memory deficit, but also by a difficulty of subject to incorporate an imaginary history in his memory (narrative identity), particularly when reality is not coherent with the imaginary history.
