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.
拔毛癖目前被归类为未另作分类的冲动控制障碍，而除拔毛外的身体聚焦行为可能被诊断为刻板运动障碍。一些以重复性身体聚焦行为（如抠皮肤）为特征的障碍很常见且会导致功能障碍，并且可能在现象学和心理生物学方面存在重叠。这些障碍在官方疾病分类学中应得到更多认可，而且将它们归为同一诊断类别似乎具有临床实用性。
