Clinical review of DBS for Tourette Syndrome.

Deep brain stimulation for Tourette Syndrome is an emerging therapy for patients with severe, disabling tics. The complexity of symptoms associated with TS present challenges for electrode target selection and evaluation of outcome that distinguish it from other disorders for which DBS has been studied. Accumulating data have been sufficiently promising to justify further study. Yet, many questions remain. Systematic, controlled, collaborative studies are required to answer the many questions that remain.
