"Asperger's" and "autism" used to be classified differently in the DSM, and they (crudely) captured this difference. In DSM-5 (2013), they've both been merged under "autism spectrum disorder", in part because there's no widely agreed upon diagnostic criteria to differentiate the two.

I can't speak for whether this has been a net positive or net negative on the clinical side of things, but culturally, these sorts of conflicts seem to be happening with higher frequently since the merge.
