There is not a magic pill to cure it...
in fact, there is no cure. But, most
kids get better on their own
in time. If the symptoms become very disruptive, antidepressants and/or seizure medicines have helped some. But, I am not a fan of medicines for TS unless it is very severe. It doesn't sound like your son is in that category. You should read some info on the Tourette's Syndrome Association website.
