Body Focused Repetitive Behavior Disorder
Symptoms
Some people with body-focused repetitive behavior disorder do these activities somewhat automatically—without thinking about it. Others are more conscious of the activity. People do not engage in these behaviors because they are obsessed with or concerned about their appearance (as occurs in Body Dysmorphic Disorder ). However, they may feel tense or anxious just before they do them, and doing them may relieve that feeling. Afterward, they often have a sense of gratification. People may also be distressed by their loss of control and repeatedly try to stop the activity or do it less often, but they cannot. If people bite or pick at their nails a lot, the nails may become deformed. Grooves and ridges may develop in the nails, or blood may collect under the nail, producing a purple-black spot. Other behaviors can cause bleeding.
