Extract

To the Editor: Generally associated with right hemisphere and frontal lobe pathology, reduplicative paramnesia is a content-specific delusion that a familiar place has been duplicated or relocated. We present a patient status after a right fronto-temporal cerebrovascular accident (CVA) who subsequently developed reduplicative paramnesia.The delusional misidentification syndrome (DMS) is a rare neuropsychiatric phenomenon that can occur in both medical and psychiatric conditions. Reduplicative paramnesia (RP) is a content-specific DMS in which a patient misidentifies a familiar place, with delusional conviction.1 There does appear to be a consensus that RP may have a neurologic rather than psychiatric cause and that right and bifrontal lesions are common factors in its presentation.2 We present here the case of a patient with new-onset reduplicative delusions status post-right frontotemporal infarct.
