6A06 Stereotyped movement disorder

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

Stereotyped movement disorder is characterised by the persistent (e.g., lasting several months) presence of voluntary, repetitive, stereotyped, apparently purposeless (and often rhythmic) movements that arise during the early developmental period, are not caused by the direct physiological effects of a substance or medication (including withdrawal), and markedly interfere with normal activities or result in self-inflicted bodily injury. Stereotyped movements that are non-injurious can include body rocking, head rocking, finger-flicking mannerisms, and hand flapping. Stereotyped self-injurious behaviours can include repetitive head banging, face slapping, eye poking, and biting of the hands, lips, or other body parts.
