Reduplicative Paramnesia after Right Frontoparietal Infarction -A Case Report-

ABSTRACT

Reduplicative paramnesia (RP) is one of delusional disorders characterized by false belief that a familiar place, person, or object had been duplicated. There have been several hypotheses about anatomical basis of RP, and right hemispheric pathology combined with or without diffuse bifrontal pathology is commonly accepted. We report a 74-year-old man who developed reduplication of place and person after right frontoparietal cerebral infarction. On the neuropsychological examination, the patient showed marked deficit in several parts of cognition including attention, memory and execution. In accordance with the literature, our clinical report suggests that RP is associated with right parietal and frontal lesion which causes deficits of visuospatial attention, memory and integration, and also emotional confusion during hospitalization.
