This important study, published in the December 4, 2007, Proceedings of the National Academy of Sciences, suggested, but did not confirm, that a developmental delay in the brain’s cortex may cause symptoms of attention deficit hyperactivity disorder (ADHD). Once the cortex matures, many kids with ADHD seem to outgrow the disorder.
While headlines in the press proclaimed “ADHD Riddle Solved,” most articles left out researchers’ warnings that the findings should not be taken as permission to stop ADHD medication. In fact, a forthcoming study shows that the cortex is more likely to reach maximum growth in those with ADHD who remain on meds.
Brain imaging is helping us learn more about ADHD. But, until we know more, if medication helps your child, keep administering it.
