Yea, my concerns are threefold: overdiagnosis, the diagnosis of young children, and the impact of treatment on developing children. I don&#x27;t doubt that ADHD is a real disorder, but if the true rate of occurrence is 2-5% while the US diagnosis rate is 10%, that means that a huge proportion of American kids are overdiagnosed. And the leading treatment for ADHD is quite intense: lifelong use of very powerful drugs, with no real understanding of how that impacts normal child development.<p>I would be surprised if exercise alone works for people who struggle with a very disabling condition, but I suspect interventions less extreme than a full ADHD diagnosis and medication regimen would do a lot of good for kids who might otherwise be overdiagnosed as ADHD.<p>And as far as the concern as to whether the 95% should change to accommodate the 5%, what we&#x27;re talking about here is &quot;getting more exercise&quot;—and when huge numbers of schools don&#x27;t require recess—it&#x27;s something that the 95% would benefit from.
