Abstract
- We report a case of rabbit syndrome in a 28-year-old man with chronic active epilepsy and mental retardation. He developed fine and rhythmic perioral involuntary movements with mild parkinsonism several months after he had been administered with neuroleptics. His movements had a rhythmic pattern consisting of 2-3 Hz with a resting period for 1- 2 seconds. They were remarkably reduced with benztropine. Parkinsonism also improved with benztropine.
