Children with ADHD have some smaller brain regions, study shows


People with attention-deficit hyperactivity disorder have distinct differences in their brain structure, a new study finds, suggesting the disorder should be considered a neurological condition and not simply a behavioral problem.

The research — published Wednesday in Lancet Psychiatry — was described by its authors as the largest-ever review of ADHD patient brain scans.

The scientists evaluated MRI scans and other data from more than 3,200 people, comparing 1,713 patients who had been diagnosed with ADHD to a control group. The patients ranged in age from four to 63.
