Abstract
We investigated six Japanese autopsy cases of Pick's disease with Pick bodies (PDPB) both clinically and pathologically, and examined the distribution of their cerebral cortical lesions using hemisphere and/or bisphere specimens. The lesions were classified into three categories (slight, moderate, and severe). Two patients with a clinical diagnosis of primary progressive apraxia and of slowly progressive aphasia had speech apraxia as their initial signs, and the other two patients were suspected as having Alzheimer's disease, with the clinical diagnosis of the remainder two patients being presenile dementia and depression, respectively. Extrapyramidal signs, believed to be rare in PDPB, were present in four patients. Severe lesions were multicentrically present in the cerebral cortices of all six cases. In two patients with speech apraxia, severe lesions were seen in the primary motor area, which generally has not been regarded as an "atrophic center" in Pick's disease. Furthermore, in a patient with depression, severe lesions were more widespread in the convexity than in the orbital region of the frontal lobe. The parietal lobes, including the postcentral gyrus usually believed to be spared in Pick's disease, were severely involved in three patients. We postulate that the clinical features of PDPB have a much wider spectrum than previously believed. In addition, we believe that the distribution of the cerebral cortical lesions in PDPB is more widespread than previously assumed, and that clinical manifestations of PDPB depend to some extent on the topographic distribution of the cerebral cortical lesions.
