This is not new, though prolonged lockdown exacerbated it. Before the pandemic, a quarter of all American teenage girls got put on psych meds, and a quarter of all boys were labeled ADHD by age 17. There's a combination of (a) real increase in problems from environmental toxin exposures; (b) real increase in problems from suffocating bubble-wrap parenting [problems caused by a lifetime of screen staring fall into both of these]; and (c) the medical establishment's labeling every minor who has unpleasant feelings or resists doing what he/she is told as a lifelong mental defective.

Oh, and in the "dys" category, "dyslexia" doubles when schools fashionably refuse to use phonics, since it turns out that most kids who haven't learned to read before age 6 never will learn to read fluently if taught by idiotic whole-language methods. I think it fair to surmise that a fair fraction of "dyscalculia" could be due to sh***y math teaching methods as well. I have a relative whose family home-schooled their kids and while this left them obviously deficient in some ways (they were trained to believe that the earth was 6000 years old), the kid who had been labeled dyslexic was able to use a special brain-retraining course that left her able to read easily. On balance I thought that was a plus; if she ever develops the desire to read something that isn't the bible, at least she'll be able to.
