To be fair, this response was likely written in response to the second paragraph of my comment, which I have since removed (since it could be read to mean exactly what the comment in question understood it to). So it’s probably not as uncharitable as you think from reading it in its current context.

> we've seriously fucked our own society in ways that aggravate this

My money is on this option. We have so much more things to cope with, and so much more change in these things to cope with, than we would have had 1000 years ago. I can imagine that this constant information overload would push some people over the edge that would have functioned well in an earlier society.

(Disclaimer: I'm not a specialist in psychiatry or anything like that.)

There's also the possibility that we're patholgizing normal behaviour. I'm not leaving that out as an option.

Incidence rate is probably higher than you think. Average college enrollment rate is less than 50%. Worse, 25% of kids drop out of high school. Also the kids who have been expelled due to behavioral problems.

>we've seriously fucked our own society in ways that aggravate this, and medication is at best a stopgap.

My gut feeling is that overcoming this is a big part of the true solution.
