Stereotypies

Stereotypies are repetitive, rhythmic, seemingly purposeless movement patterns. Primary stereotypies are typically described in healthy children with normal development, stereotypies with a trigger in adulthood are significantly rarer. The prevalence of primary stereotypies is reported between 3 and 8 %. Secondary stereotypies appear either as a result of sensory deprivation, social isolation or as part of broader syndroms in many, especially neurodevelopmental diseases, in psychiatric diseases or drug-induced syndromes. In the genesis of stereotypies, both neurobiological mechanisms, including genetic disposition, and the effects of the external environment and social interactions are considered. The basic therapeutic procedure are education and behavioral therapy, unfortunately there are no randomized, double-blind studies for pharmacological procedures.
