Body Focused Repetitive Behavior Disorder
Key Points
Body-focused repetitive behavior disorder involves repeatedly engaging in body-focused behavior such as nail biting, lip biting, and cheek chewing. These body-focused behaviors are not triggered by obsessions or concerns about appearance but may be preceded by a feeling of tension or anxiety that is relieved by the behaviors, often followed by a feeling of gratification. Patients with this disorder typically try to stop their behavior or to do it less often, but they cannot. Treat with cognitive behavioral therapy (usually habit reversal training) and sometimes medications, includingN-acetylcysteine, SSRIs, orclomipramine.
