Medline ® Abstract for Reference 44

Head banging is a rhythmic movement disorder (RMD) along with headrolling and bodyrolling. The average age of onset is 9 months, and by 10 years of age the majority of subjects no longer complain of head banging. A case of head banging in which the symptoms continued to adolescence is reported. The RMD involved the patient abnormally rolling his body or head and hitting his head on walls during sleep. His head bangings were observed during sleep stage 2 and REM sleep. Doses of clonazepam ranging from 0.5 mg to 2 mg were administered for the RMD, which diminished when treated with 2 mg of clonazepam.
