Visual cortex abnormalities in adults with ADHD: A structural MRI study

Abstract

The unexpected finding of visual cortex abnormalities might be related to impairments in early-stage, 'subexecutive" attentional mechanisms. The results support the notion that executive dysfunction may not be the dominant neurobiological characteristic of ADHD at least in adult patients. The visual cortex deserves more consideration as a potentially important site of dysfunction in adult and possibly childhood ADHD.
