I have seen kids with similar problems here in Ohio. Several of the parents have used a casein and gluten free diet and swear by it. They say that there is amazing improvement in their child's attitude and behavior. Parents also state that it usually takes a few weeks of doing the diet to notice the effects because everything else has to get out of the child's system. I don't think it's real easy in the beginning but it gets easier with practice and if it does help his behavior and attention then it is well worth it. Good luck and let me know if I can be of help.
