Reduplicative Paramnesia: A Neuropsychological case analysis

David V Nelson

The delusional misidentification syndromes, including reduplicative paramnesia (RP), are relatively rare and very incompletely understood. Reported here is a case of RP that involved strong adherence to a belief in duplication/relocation of a familiar place. Electrophysiological and neuroimaging findings converged with those obtained from extensive neuropsychological testing to identify neuropathology primarily of the right frontal-temporal-parietal region associated with a grade IV astrocytoma. The corresponding in-depth analysis of neuropsychological assessment findings presents a pattern of cognitive functions of potential interest for better understanding RP.
