What To Do For Tourette S Syndrome In Child?

Hi, may I answer your health queries right now ? Our child developed Tourette s syndrome. She is 9 years old. She has vocal and motor tics. It started last April with intermission during Jan-Feb this year; but now it is worse than ever. Family history is negative for Tourette s syndrome. Her neurologist said to come back to see him only if we want antiderpressants. We are in shock. After reading on line articles we have questions: 1. can magnesium supplements help 2. can probiotics and low carb diet help 3. could her symptoms be related to the fact that she needed braces-unilateral jaw extension? Her symptoms started 3 months after she started orthodontic treatments. 4. what can we do to help except of ignoring her tics as suggested by her neurologist. Thank you.Please type you
