A new study led by a University at Buffalo researcher has identified how specific communication among different brain regions, known as brain connectivity, can serve as a biomarker for attention deficit hyperactivity disorder (ADHD)...The findings, published in the journal Frontiers in Physiology, have implications for not only detecting ADHD, a common but diagnostically slippery disorder that's difficult to identify, but can also help clinicians target treatments by understanding where patients sit on a broad-spanning continuum.
