Brain Protein Not Correlated to ADHD?

Based on a brain imaging study, scientists conclude that a protein previously thought to be a marker for ADHD is not correlated with the disease. Compared with control subjects, researchers discovered that ADHD patients have lower levels of the dopamine transporter proteins. But ADHD patients had much higher levels of inattention for any level of the dopamine transporter. The results of the study suggest that the severity of inattention in ADHD cannot be accounted for by dopamine transporter levels alone.

U.S. Dept. of Energy's Brookhaven National Laboratory along with Mount Sinai School of Medicine from New York conducted this study. Research results will be published in the journal Neuroimage.
