High dopamine transporter levels not linked to attention-deficit hyperactivity disorder

Results from a brain-imaging study conducted at the U.S. Department of Energy's Brookhaven National Laboratory in collaboration with Mount Sinai School of Medicine in New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease.
