Attention-deficit/hyperactivity disorder (ADHD) is a real disease
linked to changes in production of the brain chemical dopamine, two new
reports suggest.
In the first report, researchers found that a variant of the dopamine receptor gene may help cause the behavioral condition but also improve its long-term outcome. "If you have a certain variant of this gene, you have a greatly increased risk of having ADHD," said lead researcher Dr. Philip Shaw, a researcher in the Child Psychiatry Branch at the U.S. National Institute of Mental Health. However, "what we found that was surprising was that having this variant was also associated with having a better outcome from ADHD," he said. "The kids who had the risk gene tended to get better," Shaw said. "They also tended to be a little bit more intelligent."
