ADHD patients may have lower functional connectivity in certain brain regions, study finds
An analysis of data from five large-scale studies found somewhat lower white matter fractional anisotropy in certain regions of the brain in persons diagnosed with attention deficit hyperactivity disorder (ADHD). Fractional anisotropy is generally considered an indicator of connectivity in the brain. Similar microstructural anomalies were not present for anxiety, mood, or externalizing problems. The study was published in Biological Psychiatry.
