Tourette Syndrome Deep Brain Stimulation

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to evaluate the effectiveness and safety of deep brain stimulation (DBS) as a possible new treatment for Tourette Syndrome (TS). This investigation will (1) test the hypothesis that centromedian (CM) continuous brain stimulation will be an effective, safe method for the treatment of tics in medication refractory TS, (2) will define the intra-operative and post-operative physiological changes, and (3) will test the hypothesis that responsive brain stimulation (RBS) will provide an alternative to chronic DBS in TS.

Clinical Trial Description

Normal clinical care for TS includes cognitive behavior therapy, medication, supportive psychotherapy, and/or a combination of the two. To meet entry criteria for this study, you must have already tried these methods and they did not help your symptoms. DBS is considered experimental for the treatment of TS and would not be done as normal clinical care. Participation in this study will require extensive pre-surgical screening to determine eligibility for DBS surgery, a DBS surgical procedure, and regular follow-ups. Subjects will be seen monthly post surgery for 6 months. After 6 months, data will be assessed and RBS may be offered as a stimulation setting. If so, the stimulator settings will be changed from chronic to responsive. If not, the subject will continue to receive chronic DBS stimulation. Subsequent visits will be scheduled every 6 months until a total of 24 months of study participation. At the end of the initial 24-month study period, subjects will have the choice of 1) continuing active stimulation at the current setting, 2) continuing stimulation but searching for a new setting, 3) discontinuing stimulation (turning the device off), 4) having the device removed. If the subject continues to receive active stimulation, they will be followed by the PI and seen at yearly intervals until the DBS system is commercially available, FDA approved for the treatment of TS, or unavailable for patient use. ;
