We report a 52-year-old Japanese woman who de-veloped dyskinesia, epilepsy, and gait disturbance. She was well until 35 years of age, when she noted the on-set of gait disturbance. She also noted abnormal invol-untary movements in her limbs. She also noted dysar-thria at age 38. A neurologist examined her at age 41. The neurologist found cerebellar ataxia and dyskine-sia. The atrophy of the brain stem and the cerebellum was on CT. She started to have generalized convulsion with loss of consciousness. Dementia became appar-ent at age 40.
