I am so confused and the more I research the more confused I get. My son was diagnosed with SPD, but his OT now a year later says ADHD, and his pediatrician says high functioning autism. He is very smart, has a huge vocabulary, has been talking since he was 5 months old. He is very aggressive, seems angry and unable to control any impulses. He constantly moves his shoulders up and down and grinds his teeth. after a few months of huge improvement, he is now into about 6 weeks of regression. I've also heard of a dyspraxia diagnosis.
What is all of this and how does SPD fit in? Is it part of a larger problem, is it considered a spectrum or on a spectrum of disorders? You can see how a diagnosis of SPD can be so hard to understand. I am ready to try Feingold diet, gluten free and detox of heavy metal poisoning, chelation and other things (not all at once of course) but I'm not going to delay trying things due to lack of consensus by his dr. and therapists.
