athetosis

A neurological disorder featuring involuntary, slow writhing movements of the hands, arms, face and tongue caused by a form of CEREBRAL PALSY. The commonest causes are ERYTHROBLASTOSIS FETALIS from rhesus incompatibility and brain lack of oxygen during birth. Intelligence may be unaffected but there is usually severe speech difficulty and the appearance suggests mental retardation to the observer. Seizures are common.
