It seems to me that for the purposes of living life, the conditions we call Aspergers and Autism have a lot of commonalities. After some initial bias, I have found the autism label to be more useful. I'm still hoping to learn from how people deal with life and this is a bigger similar pool. If someone who is non-verbal can teach me how to handle light stimulation better, I'm all for it. The spectrum is multi-dimensional - it's not just about impairment or "function."
Brain researchers will be more interested in timing and details about a spectrum of impairments, and they will come up with more labels. There's lots of responses, outcomes, genes, etc. Someday we may have better sub-labels, for what they are worth, but it's still pretty fuzzy even to the "experts" now.
