We report a right-handed 62-year-old man with early onset familial parkinsonism. The patient was well until 24 years of the age when he noted an onset of resting tremor in his right hand. During the next four years, he noted rigidity, bradykinesia, and dif-ficulty in walking. He was seen in another hospital at 28 years of the age, where he received left pal-lidotomy. Rigidity on the left side showed markedimprovement. He received right pallidotomy at age 30 years. He developed right hemiplegia after this surgery. He was admitted to our hospital in March, 1983 when he was 51 years of the age.
