Behavioral aspects of trichotillomania.

Trichotillomania is characterized by an inability to resist urges to pull out hair. It is estimated to occur in at least 1 out of 200 persons by college age. The disorder usually begins in childhood or adolescence with a chronic course more likely in patients with a later onset. Some investigators hypothesize a relationship between trichotillomania and obsessive compulsive disorder, but this proposal has not yet been substantiated. Little rigorous treatment research has been done, but the current treatments of choice are clomipramine and behavior therapy (habit reversal training).
