| Brief Summary | In this single-center trial, we aim to include 8 patients with severe and medically refractory Tourette's syndrome. All patients undergo deep brain stimulation surgery with two electrodes located in the centromedian-parafascicular complex. Tic severity and secondary outcome measurements are assessed six and twelve months after surgery. Additionally, a short randomized, double-blinded sham controlled crossover sequence of 24 to 48 hours in either active or sham stimulation is implemented after both 6 and 12 months assesments. Subjects and clinicians are blinded to treatment allocation. | ||||
