Dementia-Parkinsonism syndrome with numerous Lewy bodies and senile plaques in cerebral cortex.
Five cases of age range 62-72 years with progressive dementia and muscular rigidity are reported and discussed from the clinicopathologic point of view. The neuropathology of these cases was characterized by the widespread occurrence of Lewy bodies (LB) in the CNS as well as the presence of senile changes. The presence of numerous LB in the cerebral cortex and basal ganglia was especially characteristic, although their distribution pattern in the diencephalon and brain stem was identical to that found in paralysis agitans. On the other hand, the presence of senile changes in the cerebral cortex was almost identical to the neuropathology of senile dementia or Alzheimer's disease. Nosologically, the present cases may represent either a combination of atypical paralysis agitans with senile dementia and Alzheimer's disease, or a new disease.
