These data provide support for the use of D-cycloserine as an augmentation of behavior therapy for OCD and extend findings in animals and other human disorders suggesting that behavior therapy acts by way of long-term potentiation of glutamatergic pathways and that the effects of behavior therapy are potentiated by an NMDA agonist.

In study 1, 46 children and adolescents with trichotillomania who sought treatment at 2 specialty outpatient clinics were assessed. Most children reported pulling hair from multiple sites on the body, presented with readily visible alopecia, reported spending 30-60 minutes per day pulling or thinking about pulling, and reported experiencing significant distress about their symptoms. Most were described by their parents as having significant problems in school functioning. Few children met criteria for obsessive-compulsive disorder or tic disorder. Child and family rates of other forms of psychopathology were high. In study 2, 22 of these children were enrolled in an open trial of individual cognitive behavioral therapy with particular attention to relapse prevention. Trichotillomania severity decreased significantly and 77% of children were classified as treatment responders at post-treatment and 64% at 6-month follow-up.
