  • Abstract
  • Look Inside

 Four cases of DRPLA were studied neuropathologically. The main pathological lesions were found not ony in the dentatorubral and pallidoluysian systems, but also in the tegmentum of the lower brainstem as well as in the spinal cord. In the dentate nuclei, there were severe rarefaction and dense gliosis. The majority of the remained neurons showed atrophic, vacuoral and chromatic changes. The clusters of degeneratedterminal buttons at the site of missing neurons-so called grumose degeneration-were also observed. However, Purkinje cells and the granural layer of the cerebellum were almost intact.
