Autism is a shut down of part of the mind in order to block receiving more information, such as people talking, emotions generated by a caretaker or parent, wandering spirits, cell phone frequencies, wireless microwave frequencies, etc. Autism is a type of shock state. When you are involved in an accident or witness something horrifying, your mind protects you by shutting down so that you cannot continue to be harmed by sensory input. At that point you cannot relate well to the outside environment. Little by little you come out of the state of shock, once again receiving information via your senses. If you die before coming out of the shock, you are not reborn autistic.
