[Gilles de la Tourette-syndrome: treatment of a neuropsychiatric disorder].

The Gilles de la Tourette-Syndrome (GTS) is a tic disorder with both motor and vocal tics. A tic is an involuntary, fast, sudden und stereotyped movement or sound. According to international guidelines the therapy consists of pharmacologic, psychotherapeutic and neurosurgical approaches. Antipsychotics are the most effective pharmacotherapy. Psychotherapeutic approaches play a more subordinated role. Deep brain stimulation is experimentally applied in intractable GTS.
