I am sorry to hear about the struggle your son is facing. And I can only imagine how hard it is for you guys as his parents to cope with it as well. My son is not showing as severe symptoms. But there is a problem some times at school because he can have a very limited attention-span. He recently started high-school, and he seems to be doing better overall there. His grades are better, he seems more content, and calmer in a way. So I am not stressing it right now. But there is a parent-teacher meeting coming up soon, and then I will know more about how he does in class etc.
