Study population: Patient with Tourette syndrome eligible for bilateral deep brain stimulation of the anterior internal pallid globus

Brief summary: Within an ongoing deep brain stimulation (DBS) program for Tourette syndrome (TS) at the Department of Neurology, Pitié-Salpêtrière Hospital, Paris/France, the investigator team plans to evaluate patients pre-operatively and then at one year intervals post-operatively until the 5-year mark has been achieved. The investigator team will investigate tic severity, psychiatric co-morbidities, quality of life, and neuropsychological measures.

Detailed description: Since the completion of the STIC trial in 2017, the french team continues to offer DBS of the globus pallidus internus (GPi) to selected, treatment-refractory patients with TS. On average, three to four patients undergo surgery every year. Even though a first follow-up of the STIC cohort up to four years post-op indicates ongoing improvement of tic severity, many questions remains regarding the efficacy of GPi DBS in TS. These questions include frequent comorbidities of TS, quality of life, evolution of medication and stimulation parameters, as well as neuropsychological functioning. Therefore, the investigator proposes to evaluate all patients undergoing GPi DBS for TS to be evaluated comprehensively pre-operatively and once yearly after surgery until reaching the 5-year mark. The investigator team hopes these data may help to plan for future international multicenter trials, and provide indications on prognostic factors concerning response to GPi DBS in TS.
