Why not go and research that for yourself? I don't wish to be uncivil but I've heard this question so often for the last 20 years that I now regard it as little more than concern trolling. I get it, it's hard to make meaningful quantitative statements about a behavioral disease whose clinical parameters are hard to define.

But it's a naive point and this subject has been a topic of public debate for a long time now, so the skeptical signalling gets really tedious after a while. It's about as enjoyable as if I described your work as a computational scientist as 'pushing buttons all day' or made some crack about it being an excuse to play video games, as a way of signaling a lack of regard for nerdy pursuits.
