Isn&#x27;t it normal to have difficulty focusing on things that are really boring?<p>ADHD diagnosis rates are several times higher in the US than in other developed countries, and orders of scale higher than in low-diagnosis countries (such as France). The biggest risk factors for an ADHD diagnoses include things like &quot;being male&quot; and &quot;being in the youngest quartile of your kindergarten class&quot;. That&#x27;s an amazing thing to pathologize. In the US, the drive to perform well on standardized tests has gotten to such an extreme that kindergarteners are expected to have literacy performance that was expected of 1st-graders a generation ago, and children are expected to <i>come</i> to kindergarten with the alphabet knowledge that they would have learned in kindergarten a generation ago. Meanwhile, the amount of time young children have spent at recess has declined hugely in the last 30 years, with very many schools having no recess at all.<p>Isn&#x27;t there a margin where this is a disorder because of the interaction between an individual and their environment, where the environment is the problem?<p>Some amount of ADHD-spectrum behavior might should be considered within the range of normal child development, which is being pathologized by a system that doesn&#x27;t give young children (especially slightly younger boys) enough exercise. The main treatment for ADHD is lifelong amphetamine use, and nobody can say whether this treatment prevents children from developing coping mechanisms that they would otherwise normally develop before adulthood.<p>If something as simple as more exercise can marginally reduce ADHD diagnosis or medication rates, that would be a huge advance.
