Posted: October 15, 2010 – A study published this summer in the American Journal of Psychiatry investigated why food additives cause some, but not all, ADHD children to experience worsened symptoms. The researchers found that genetic variation may account for the difference.
This study highlights that there is no simple way to define ADHD. Because it is a diagnosis of more severe inattentive behavior (on a sliding scale) with various root causes, it is difficult to know how best to intervene. That is why Cogmed focuses on improving poor working memory, which is often a root cause of severe inattention problems.
