my son has a lot of health issues also. i have taken him to environmental doctors all over the country, but found the best results with a caring doctor in portland, oregon, who treated him for lead and mercury poisoning. my son is also nine years old, and will be ten in august. we found that he had severe malabsorption, leaky gut, and a severe yeast overgrowth. he also had a faulty liver because of the heavy metals. it can't break down caffeine or preservatives. we got the malabsorption and yeast overgrowth corrected with a sugar-free diet, as well as nystatin. that is when he started getting better. he also stays away from caffeine and preservatives. as long as he does that, he is pretty much a typical boy. he will start fifth grade in august, with no aide.
my suggestion to you is to make sure that the yeast overgrowth is gone. you can get a test kit from the great smokies lab in north carolina, or the great plains lab in missouri, i believe it is. i strongly feel that your child can improve once his intestional integrity is restored. your son can get better. i truly believe that. terresa
