Antiepileptic drugs for Tourette's syndrome

To assess:

  1. whether antiepileptic drugs (AEDs) improve outcomes without excessive adverse events in people with Tourette's syndrome (TS) compared to placebo or no treatment, in the presence or absence of concurrent treatments for TS;
  2. whether AEDs improve outcomes without excessive adverse events in people with TS compared to other established treatments for TS.

This is a protocol.
