Clinical approach to motor stereotypies in autistic children.

This is an overview of stereotypic behavior in autistic spectrum disorder (ASD). This repetitive, nonfunctional, fixed pattern of behavior is associated with autism severity but it is not specific for ASD. There are a wide range of behaviors mentioned as stereotypies. It usually starts in early childhood and its severity is associated with outcomes and severity of autism in adolescence and adulthood. It is usually co-morbid with other psychiatric problems and its pathophysiology is not exactly known. Management is most likely behavioral. There are some reports regarding efficacy of antipsychotics for its management. Further studies should be conducted to improve our knowledge about it and our ability to differentiate it from tics.
