My son has TS and we recently heard about the possible links with gluten. I am gluten intolerant, so it might make sense that my son would be also. We experimented with GF diets for him and my daughter and they both seem to benefit. They stay a lot calmer, happier and more focused and my son's tics definitely seem better controlled. If we re-introduce wheat, we see the opposite. I worry, however, that a complete GF diet might make them even more sensitive to the smallest exposure to gluten.
