This is just a suggestion, but given what I've read, I would seek out a prosseional who specializes in the diagnosis of autism spectrum disorders. There seems to be alot in common with the combination of allergies, ear infections, and behavioral/emotional problems among children who are later diagnosed with autism or asperger's....also, it is common for these children to receive initial diagnosises of what you have said your son has been diagnosed with: ADHD, ODD & has anxiety disorder. I work at a center teaching students with autism, and providing consultation services for families, and a;most all the stories are the same from what you're describing, additionally, all too often, children not receiving the diagnosis of autism when they are your sons age, but are reevaluated later and diagnosed with it (usually around age 10) but they have already missed out on so many years of intervention that they do fall behind socially and academically....

The dietary changes are definitely going to help, no matter what your chlid's diagnosis, but when he gets into school, it will help him to be accurately diagnosed so that his teachers can understand more the underlying reasons for his behaviors, and they can help (as opposed to punish)him when he shows resistance/difficutly to tasks or socialization skills.

Best of Luck! I hope this information helps.

I have seen changes in behavior and emotions with the gleuten-free and dairy free diets, and there needs to be otehr interventions as well.
