We report a 78-year-old man with progressive gait disturbance, dementia, and dysphagia. He was apparently well until 75 years of age in 1989 when he had an insidious onset of gait disturbance. In October of 1991, he was treated with levodopa and amantadine HCl in another hospital, but he develo-ped visual hallucination right after these medica-tions, and the drugs were discontinued. He also developed difficulty in swallowing with frequent aspiration pneumonia. He was admitted to our hospital on January 13, 1992.
