Connection maps of brain areas are helping reseachers study the causes of ADHD

New research suggests that the neural network that controls attention may develop more slowly in children who have attention deficit hyperactivity disorder (ADHD). While previous research suggested that the brains of children with ADHD develop more slowly, this new research was able to detect changes in connectivity within and between key brain regions.
