Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals with severe, drug-resistant Tourette syndrome who are eligible for bilateral deep brain stimulation.

Probably not a fit

Patients who do not have Tourette syndrome or those who are not eligible for deep brain stimulation may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates patients with Tourette syndrome who are undergoing bilateral deep brain stimulation (DBS) at the Pitié-Salpêtrière Hospital in Paris. Patients will be assessed pre-operatively and then annually for five years post-surgery to monitor tic severity, psychiatric co-morbidities, quality of life, and neuropsychological functioning. The goal is to gather comprehensive data that may inform future multicenter trials and identify prognostic factors for response to DBS in Tourette syndrome.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the long-term effects of DBS on Tourette syndrome and improve treatment outcomes for patients.

How similar studies have gone: Previous studies, such as the STIC trial, have shown ongoing improvement in tic severity with DBS, indicating potential success for this approach.
