[Tourette syndrome--in the borderland between neurology and psychiatry].

Tourette syndrome is a hereditary tic disorder. The symptoms consist of compulsory movements and vocalizations. Stress has an aggravating effect on tics. Unfortunately tics are easily mistaken for oppositional and defiant behavior. Tourette syndrome is most frequently seen with psychiatric comorbidity. Tics are best treated with low arousal techniques, which may be supplemented with pharmacotherapy.
