Why do we only see younger children with Autism?

[Happy]

The reason you only tend to see younger people and children with autism is because it is such a recent diagnosis. Autism was only relly recognised in the 1940's, first by Kanner and then by Asperger. Before they began to research the condition children who would now be classified as having an autistic spectrum disorder were thought of as being slow or eccentric. I have a relative who was recently diagnosed at the age of 69 as having Asperger syndrome. Through out his entire life we have thought of him as being odd and a bit of a loner. When he was finally diagnosed it all made sense, although it does not change him.
