Sleep-related rhythmic movement disorder (Q41115)

Sleep related rhythmic movement disorder is characterised by repetitive, stereotyped, and rhythmic motor behaviours that involve large muscle groups (e.g., banging head against pillow or mattress, head rolling, body rocking, body rolling). The symptoms are sufficiently severe to result in significant distress or impairment in personal, family, social, educational, occupational or other important areas of functioning (e.g., due to frequent disruptions in sleep) or result in bodily injury (e.g., due to falling out of bed).
