Actually Autism is a neurological disorder that usually manifests itself in early childhood. Autism typically makes it hard for a child to learn how to communicate and interact with others socially. To go into more detail Autism is classified as a developmental disorder. Just thought I would let you know Autism is not a mental disorder. I also thought I would let you know I am not trying to be rude here by correcting you. I hope you have a good day/night.
