Abstract

Reduplicative paramnesia refers more often to places than to time or to persons. We report here the case of a 16-year-old student who, after a severebrain injury, presented the delusion of a double who was 1 year younger than himself and with no physical impairment, This patient presented a severememory deficit, particularly in the verbal modality, uninhibited behaviour, decreased self-awareness, difficulties in planning and impaired mental flexibility. There were no visuo-spatial or autotopognosic deficits, His delusion diminished over 2.5 years and, at the same time, learning and executive functions returned to normal, However, a retrograde amnesia of 1 year persisted. This observation is in line with Staton et al.'s (Cortex 1982; 18: 23-36) hypothesis about reduplicative paramnesia being a functional disconnection between past mnesic information and the ability to integrate it withactual experiences, Magnetic resonance imaging showed bilateral frontal contusions more severe on the left side, a small left anterior thalamic contusion, and a secondary atrophy of the left hippocampus and the left anteriortemporal pole, The role of the left temporal paralimbic post-traumatic lesions in relation to reduplication of self is discussed.
