My son was diagnosed with autism at age three.Read the book The Ultimate stranger by Carl H. Delacato. He has autism clinics all over the world. Also see a good neurologist that is familar with autism. My son is 11 now and they now found out he doesn't have autism,he has dopa responsive dystonia.It took three neurologists before we found one who really tested our son for everything he could think of before he found what he had. Easter Seals was also a big help with talking devises.
