    Abstract:
    An autopsy case of a 66 year-old woman is reported. She developed personality change and psychotic symptoms at the age of 58. She began to show gait disturbance and forgetfullness at the age of 60. She was admitted to Okayama University Hospital at the age of 61, when she showed personality change, dementia, cerebellar sings and chorea like involuntary movement. The illness progressed slowly and she died of septicemia at the age of 66. At autopsy brain weighed 990 g. Macroscopically, the atrophy of the brain stem was severe, and the cerebellum was slightly atrophic. Microscopically, the globus pallidus was almost intact, but the degeneration involved dentate nuclei, their projections, red nucleus and the subthalamic nuclei, so this case was considered to be a case of pseudo-Huntington form of dentatorubropallidoluysian atrophy, proposed by Hirayama. The most striking feature of this case was marked atrophy of the brain stem and her intense familial history. Investigation of her familial history revealed that there were 18 affected cases in 5 successive generations. Their onset of the disease varied from the age of 10 to 60 years old. Cases of juvenile onset showed myoclonus and convulsion as the initial symptoms, and convulsion as the initial symptoms, and those of presenile onset showed dementia, cerebellar ataxia and chorea like involuntary movement. And in some of these cases it was proved by NMR-CT that their brain stem were small. We discussed the meaning of the atrophy of the brain stem in these cases and the difference of the symptoms between the cases of juvenile onset and the cases of presenile onset.
