Autism is one of those diseases which is probably several. A cluster of symptoms which is caused by a small collection of differently or diminished functions in a set of brain systems and that altered function would be further caused by a few separate things, genetic, development environment, autoimmune, and or infection. Sort of three layers of how it presents, the brain differences that directly cause the presentation, and the underlying mechanistic causes of those differences.
