Studies have shown<unk> es associated with some types of schizophrenia. Frontotemporal dementia is also a common neurological cause of repetitive behaviors and<unk> es. Several causes have been hypothesized for<unk> , and several treatment options are available.<unk>  is sometimes called stimming in autism, under the hypothesis that it self-stimulates one or more senses.
