Exercise Is ADHD Medication
Physical movement improves mental focus, memory, and cognitive flexibility; new research shows just how critical it is to academic performance.
Mental exercises to build (or rebuild) attention span have shown promise recently as adjuncts or alternatives to amphetamines in addressing symptoms common to Attention Deficit Hyperactivity Disorder (ADHD). Building cognitive control, to be better able to focus on just one thing, or single-task, might involve regular practice with a specialized video game that reinforces “top-down” cognitive modulation, as was the case in a popular paper in Nature last year. Cool but still notional. More insipid but also more clearly critical to addressing what’s being called the ADHD epidemic is plain old physical activity.
It may potentially be advisable to consider possibly implementing more exercise opportunities for kids.
Over all, the pandemic of physical inactivity, as Hillman and colleagues put it in their Pediatrics journal article today, is “a serious threat to global health” responsible for around 10 percent of premature deaths from noncommincable diseases. But it clearly manifests in ways more subtle than deaths, including scholastic performance, which we’re continuously learning. I talked last week with Paul Nystedt, an associate professor of economics and finance at Jönköping University in Sweden, who just published a multi-country study that found that obese teenagers go on to earn 18 percent less money as adults than their peers, even if they are no longer obese. He believes that’s most likely because of the adversity that obese kids experience from classmates and teachers, which leads to both cognitive and noncognitive disparities between obese and non-obese kids. Because obese children are more likely to come from low-income homes to begin with, that only perpetuates wealth gaps and stifles mobility. Nystedt and his coauthors conclude, “The rapid increase in childhood and adolescent obesity could have long-lasting effects on the economic growth and productivity of nations.”
