Common repetitive movements of SMD include head banging, arm waving, hand shaking, rocking and rhythmic movements, self-biting, self-hitting, and skin-picking;  other stereotypies are thumb-sucking, nail biting, trichotillomaniabruxism and abnormal running or skipping. Stereotyped movements are common in infants and young children; if the child is not distressed by movements and daily activities are not impaired, diagnosis is not warranted.
There are no specific tests for diagnosing this disorder, although some tests may be ordered to rule out other conditions. SMD may occur with Lesch-Nyhan syndromeintellectual disability, and fetal alcohol exposure or as a result of amphetamine intoxication.
