Functional Rabbit Syndrome: A Case Report

Maria Stella Aniello et al. Tremor Other Hyperkinet Mov (N Y). .

Abstract

Rabbit Syndrome is a rare involuntary movement occurring in 1.5-4.4% of patients receiving antipsychotics and characterized by rapid, regular movements (4-6 Hz) of the oral and masticatory musculature resembling the chewing motions of a rabbit. Herein we describe a middle-aged woman who presented with a rabbit syndrome characterized by several clues of psychogenicity such as sudden onset, distractibility, variability and complete "miracolous" remission.

Keywords: functional; hyperkinetic movement disorder; rabbit syndrome; tremor.
