Efficient internal pallidal stimulation in Gilles de la Tourette syndrome: A case report

The usefulness of deep brain stimulation (DBS) of thalamic nuclei in Gilles de la Tourette syndrome (GTS) has recently been advocated. We report on a 14-month follow-up study of a patient with intractable GTS in whom bilateral DBS of the internal globus pallidus was carried out. Tic frequency per minute decreased by 73% in the postoperative phase and in particular the vocal tics became less intense. Pronation/ supination bradykinesia of the left extremities was a well-tolerated, permanent side effect. Pallidal DBS could become a valuable rescue therapy for otherwise intractable GTS.
