rabbit syndrome

(rab'it sin'drōm),
A rare neuroleptic-induced form of parkinsonism usually manifested as 4-6 Hz, rhythmic discharges involving the jaw, perinasal, and perioral musculature; so-named because the movements mimic those seen with the chewing movements of a rabbit.
A condition characterised by focal perioral tremors and nose twitching, which may be seen in parkinsonism as a late side effect of antipsychotic drug therapy; unlike tardive dyskinesia, the symptoms of RS respond well to antiparkinsonian agents
