Stereotypy

A stereotypy (/ˈstɛriəˌtaɪpi, ˈstɪər-, -ioʊ-/,STAIR-ee-oh-TEYE-pee or STEER-ee-oh-TEYE-pee) is a repetitive or ritualistic movement, posture, or utterance. Stereotypies may be simple movements such as body rocking, or complex, such as self-caressing, crossing and uncrossing of legs, and marching in place. They are found in people with intellectual disabilities, autism spectrum disorders, tardive dyskinesia and stereotypic movement disorder, but may also be encountered in normal individuals as well. Studies have shown stereotypies associated with some types of schizophrenia.Frontotemporal dementia is also a common neurological cause of repetitive behaviors and stereotypies. Several causes have been hypothesized for stereotypy, and several treatment options are available.
