Our oldest son is Autistic, with severe Asperger's Syndrome. While the APA has dropped the separate classification of Asperger's withing the Autism spectrum, it's still a huge challenge, even after 45 years.
He was born in 1972, at a time when Asperger's diagnosis was gathering dust on the shelf of an obscure Austrian psychologist, and Autism was "Rain Man". In fact, our son wasn't diagnosed with autism until 1989, in his junior year of high school; and he wasn't diagnosed with Asperger's until 2007, at the time he had a complete relapse of his progress with Autism.
Until Autism was diagnosed as a spectrum disorder, children like my son were diagnosed with "unknown behavioral disturbances, with no apparent cause" (the exact quote of a child psychologist).
People with Autism and Asperger's are always in danger of a relapse, even with psychological intervention, therapy, and a home life which keeps him focused.
RESCUE341 is observing his Asperger's from inside, a horrible place to try and figure out just where the problem is, and what happens when things go sideways. Our son is aware of his diagnosis, understands and can discuss Asperger's and Autism, but understanding the diagnosis and taking corrective action are nearly impossible to do. The possibility of lapsing into near non-treatment. We constantly reinforce proper social interaction, but it will never "stick". And, expecting strangers to understand Asperger's is akin to getting folks to understand astrophysical "String Theory". There are too many people out there who still believe that Autistics should act like Dustin Hoffman counting his toothpicks, and needing to watch Judge Wapner daily.
