Tourette Syndrome
Conditions
Brief summary
This research is being performed to try to understand if the use of deep brain stimulation or DBS can treat the symptoms of Tourette syndrome that do not respond well to current medications. In order to do this the investigators will place small stimulation leads on both sides of the brain in a region (a portion of the thalamus) that may alter the abnormal activity in the brain contributing to the symptoms of Tourette syndrome. This requires two surgical procedures, and several preoperative and postoperative visits for tuning the stimulation parameters and recording stimulation effects. The FDA has not approved DBS for use in people with Tourette syndrome, and Medtronic (the manufacturer of the device) has not conducted testing for the system in Tourette syndrome. Therefore its use in this study is experimental.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in the Yale Global Tic Severity Scale (YGTSS) | 1 year after neurostimulator implantation | Investigators will assess deep brain stimulation effects on tic frequency and severity using the change in Yale Global Tic Severity Scale (YGTSS) in this population of Tourette syndrome patients. The scales range from 0-100, higher scores indicate greater tic severity and impairment. |
| Number of Participants Free of Adverse Device Effects (ADEs). | 1 year after neurostimulator implantation. | We will assess the incidence of adverse device effects (ADEs) as defined by the Code of Federal Regulations (21 CFR 812.3) at 1 year. Number of participants free of adverse events by 1year post implantation is reported. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in the Yale-Brown Obsessive Compulsive Scale | 1 year after neurostimulator implantation. | We will assess deep brain stimulation effects on obsessive compulsive disorder symptoms using the Yale-Brown Obsessive Compulsive Scale (Baseline score - Final score). Score range 0-40, higher scores indicate greater severity of OCD symptoms. |
| Change From Baseline in the WHO Adult ADHD Self-Report Scale (ASRS) | 1 year after neurostimulator implantation. | We will assess deep brain stimulation effects on ADHD symptoms as measured by the WHO Adult ADHD Self-Report Scale (ASRS). |
