Behavioral and pharmacological treatments for tic and habit disorders: a review.

Children with tic and habit disorders are often seen by pediatricians, psychologists, or psychiatrists for evaluation and treatment.

This article reviews the behavior therapy and pharmacological treatment of motor and vocal tic disorders, self-destructive oral habits, trichotillomania (hair pulling), onychophagia (nail biting), and thumb sucking. The research evidence indicates that all of these disorders can be effectively treated with behavioral or pharmacological approaches.
