Just to clarify, I was in no way trying to explain where Autism comes from. Like you said, there is multiple reasons, and it's just a name to explain symptoms. I was just trying to explain those symptoms on a cellular level. Basically, the brain thing does happen to all autistics, but they just don't know WHY it happens. It's similar to Alzhiemer's disease. They know what happens to the brain-they don't actually know why-except that it may be genetic.
