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.

Figure

• 

  Fig. 1 Brain diffusion MRI at the onset of cerebral infarction showed high signal intensity in diffusion weighted image in right frontoparietal, right anterior corona radiata, right caudate head, and right upper basal ganglia, which indicated acute infarction (arrows).

• 

  Fig. 2 Tc-99m-ECD SPECT at 1 month after the onset of cerebral infarction showed markedly decreased perfusion in the right basal ganglia, and parietooccipital region (arrows).
