We report a 75-year-old man with a ten-year history of parkinsonism, who developed acute deli-rium. He was well until 65 years of age, when there was an onset of tremor in his left hand. He had been treated with levodopa and trihexyphenidyl with marked improvement. He was doing well until July of 1991 at his age of 75-year-old, when he noted backache; he was found to have a compression fracture of the third lumbar spine. He had to use a wheel-chair most of the time since then. In Decem-ber 1991, he started to have visual hallucinations and difficulty in swallowing.
