urge to compulsively pull one's own hair, i.e., trichotillomania. Researchers have noted the following similarities between trichotillomania and excoriation disorder: the symptoms are ritualistic but there are no preceding obsessions; there are similar triggers for the compulsive actions; both conditions appear to play a role in modifying the arousal level of the subject; and the age of onset for both conditions is similar. There is also a high level of comorbidity between those that have trichotillomania and those that have excoriation disorder. A notable difference between these conditions is that skin picking seems to be dominated by females whereas trichotillomania is more evenly distributed across genders. The acronym body focused repetitive behavior disorders (BFRB) is used to characterize excoriation and trichotillomania behaviors. One shared behavior is continued picking as an emotional or reward sensation. This involves the picking to resolve negative thoughts or emotions or a developed behavior of automatic picking. This automatic picking becomes habitual and is a comorbidity with ADHD. In 2018, a new study on Tourette Syndrome (TS), trichotillomania, and excoriation revealed cooccurrence of the same disorders. Participants were screened by clinical staff in clinics supporting patients with Tourette Syndrome. Those patients included then completed self-report questionnaires. Of the total number of TS participants (n = 811), 13% revealed diagnosis of trichotillomania and excoriation. This significance of results was reported with the recommendation of screening in children with a diagnosis of TS. This will assist clinicians in screening for trichotillomania and excoriation or the risk factors for both. As with the adult population of women, girls are more impacted by the disorders then boys. Research has also suggested that excoriation disorder may be thought of as a type of obsessive compulsive disorder (OCD). Excoriation disorder and OCD are similar in that they both involve "repetitive engagement in behaviors with diminished control" and also both generally decrease anxiety. Nevertheless, Odlaug and Grant have suggested that excoriation disorder is more akin to substance use disorder than OCD. They argue that excoriation disorder differs from OCD in the following fundamental ways: There is a much greater share of females with excoriation disorder. Excoriation disorder may be inherently pleasurable whereas OCD is not. The treatments that are generally effective for patients with OCD (i. e., SSRIs and exposure therapy) are not as successful in patients with excoriation disorder. Unlike OCD, picking the skin is rarely driven by obsessive thoughts. Odlaug and
