Abstract:
Trichotillomania is currently classified as an impulse control disorder not otherwise classified, whereas body-focused behaviors other than hair-pulling may be diagnosed as stereotypic movement disorder. A number of disorders characterized by repetitive, body-focused behaviors (eg, skin-picking) are prevalent and disabling and may have phenomenological and psychobiological overlap. Such disorders deserve greater recognition in the official nosology, and there would seem to be clinical utility in classifying them in the same diagnostic category.
