Summary

Double-blind randomized, sham-controlled clinical trial of 1 mA bilateral supplementary motor area in adolescents/adults with Tourette syndrome (TS). The primary objectives are to assess and quantify the safety and efficacy on tic severity of 5 inhibitory sessions of active vs. sham tDCS sessions during active tic suppression, and to explore the differences in brain functional activity before and after 5 sessions of active or sham cathodal tDCS in adolescents and adults with TS. Secondary objectives include the assessment of the severity of comorbidities after 5 inhibitory tDCS sessions.

Conditions

  • Tourette Syndrome

Interventions

DEVICE

1 mA tDCS over bilateral SMA

A 1mA direct current will be delivered through two 5cm x 5cm saline-soaked surface sponge electrodes by a battery-driven, constant-current stimulator (Neuroconn DC stimulator). First, the SMA will be identified based on the guidelines of the international 10-20 electrode system. The tDCS will then be applied using the following procedure: 1. The head of participants will be measured to find the 'vertex' (top) of the head. This point will be used as a landmark to locate the SMA. This region corresponds to the FCZ (e.g., Legon et al., 2013). 2. The return electrode will be placed over the mastoids. Once the electrodes are in position, cathodal tDCS will be applied at 1mA for 15 minutes, 2 times a day with a resting period of 20 minutes in between treatment periods, for 5 consecutive days.
