I'm not going to draw my own conclusions from the study, but I will speak from my own empirical circumstances.

One of my close friends suffers from Asperger's, and it affects him more than I'll probably ever understand. But he finds solace in MMOs because he isn't expected to pick up on social cues like facial expressions or subtleties to understand what's going on. It's easier for him.

So I'd rather not think that OMG, gamers are all undiagnosed Asperger's sufferers, but rather, hey, people with Asperger's gravitate towards online games because it allows them an avenue for social interactivity without complications.
