Stereotypy true true UMLS:C0038273 human_phenotype Stereotypic behaviors MSH:D013239 SNOMEDCT_US:5507002 An abnormality of behavior characterized by one or more stereotyped and restricted patterns of behavior such as inflexible adherence to specific, nonfunctional routines or rituals, stereotyped and repetitive motor mannerisms (e.g., hand or finger flapping or twisting, or complex whole-body movements), or persistent preoccupation with parts of objects. The behaviour does not serve an observable goal. In general the movements are not aimed at the environment, but at the person itself. Stereotypical behaviour is seen especially in children with sensory, intellectual and/or cognitive handicaps.

They may be primary (seen in otherwise normal individuals) or secondary (associated with autism, intellectual impairment and other disorders). Stereotypies can be distinguished from epileptic automatisms by the characteristic movements (a video of events can be helpful to aid diagnosis). SNOMEDCT_US:84328007 HP:0000733 HP:0008758 Repetitive movements HP:0008759 A stereotypy is a repetitive, simple movement that can be voluntarily suppressed. Stereotypies are typically simple back-and-forth movements such as waving of flapping the hands or arms, and they do not involve complex sequences or movement fragments. Movement is often but not always rhythmic and may involve fingers, wrists, or more proximal portions of the upper extremity. The lower extremity is not typically involved. Stereotypies are more commonly bilateral than unilateral. MSH:D019956 Stereotyped, repetitive behaviour Repetitive or self-injurious behavior Stereotypic behavior rare paroxysmal movement disorder
