Excerpt:
".....Kids and teens with ADHD, a new study finds, lag behind others of the same age in how quickly their brains form connections within, and between, key brain networks.
The result: less-mature connections between a brain network that controls internally-directed thought (such as daydreaming) and networks that allow a person to focus on externally-directed tasks. That lag in connection development may help explain why people with ADHD get easily distracted or struggle to stay focused.
What's more, the new findings, and the methods used to make them, may one day allow doctors to use brain scans to diagnose ADHD—and track how well someone responds to treatment. This kind of neuroimaging "biomarker" doesn't yet exist for ADHD, or any psychiatric condition for that matter.
The new findings come from a team in the University of Michigan Medical School's Department of Psychiatry. They used highly advanced computing techniques to analyze a large pool of detailed brain scans that were publicly shared for scientists to study. Their results are published in the Proceedings of the National Academy of Sciences...."
Lead author Chandra Sripada, M.D., Ph.D., and colleagues looked at the brain scans of 275 kids and teens with ADHD, and 481others without it, using "connectomic" methods that can map interconnectivity between networks in the brain.
This further validates Dr. Russell Barkley's 3 year/30% claim regarding developmental lag in social/emotional problem solving and difficulty with goal attainment...Executive Functions...
