I asked his neurologist about gluten intolerence (a few other folks have mentioned it to me along the way) and he just sort of shrugged it off... I guess it couldn't hurt to try a gluten-free diet (I wish my child wasn't such a picky eater, it would make it so much easier!) I have a sneaking suspicion that the digestive issues, whatever they may be, are playing a major role in the neurological symptoms, its just a matter of figuring out what they are and how to treat them, thanks again for your advice, I'm making a note of all of it to bring along with me when we go to the next appointment.
