On my diagnosis it says "Asperger's Syndrome", so I thought that was the correct term. I should confess that I could not remember what term they used on my diagnosis and had to find it to see. To me, it really does not make any difference, but you are right. The pros do not seem to agree on any one term.
It bothers me that professionals are not always on the same page. It inherently diminishes my faith in them as professionals.
Yet in this venue, I honestly don't care what you choose to call it. Only that I believe I have it...whatever it's called.
