Tracking Brain Stimulation Treatment for Severe Tourette Syndrome

This trial is tracking people with severe Tourette syndrome who have had a surgical procedure called deep brain stimulation (DBS) — a device placed in the brain to help control tics. The French research team wants to carefully measure how well this treatment works before and after surgery, and to understand how it affects not just the tics themselves, but also other health concerns, mood, thinking abilities, and quality of life.

Even though earlier research showed that this treatment helps reduce tics over time, doctors still have many unanswered questions about how well the treatment works for different people and what factors predict who will benefit most. By collecting detailed information from every patient treated this way, the research team hopes to better understand this treatment and plan larger international studies in the future.
