At 24-month follow-up, tic severity was improved in patients with intractable Tourette syndrome (TS) who underwent bilateral thalamic deep brain stimulation. Available data from 15 to 18 patients also showed that neuropsychiatric symptoms were improved and cognitive performances were not disadvantaged. Controlled studies on larger cohorts with blinded protocols are needed to verify that this procedure is effective and safe for selected patients with TS. |
