A new study conducted through the National Institute on Drug Abuse (NIDA) has found that an abnormality in the way the brain processes rewards and motivation may be a root cause of ADHD.

In studies past, researchers have focused on issues of attention and hyperactivity, viewing them as the primary issues -- but a NIDA release indicates that approach may need to be revised:

Recent studies have found that children with ADHD dont respond to rewards in the same way as children without ADHD, [lead researcher Nora] Volkow said. In addition to the classic symptoms of inattention and hyperactivity, there is also a disruption in motivations and sensitivity to rewards, she said.

This newest study found a disruption in the brains reward/motivation pathway in people with ADHD. The study also found a direct correlation between that disruption and the severity of inattention. Researchers called the study a wake up call for teachers, believing it emphasizes the importance of finding creative ways to keep kids engaged.
