There are multiple studies of ADHD brain MRI’s compared to non-ADHD brains and the differences.

I don’t wish to be contradictory but the so called brain scan studies (zametikin spelling?) studies were so seriously flawed as to be laughable. No control groups, sample sizes of 15 kids, kids taken off ritalin days prior to the P.E.T. scan add up to nothing. No subsequent tests/scans have ever relocated these findings.

"Brain imaging is still not ready for use as a diagnostic tool in ADHD," Shaw points out, "Although the delay in cortex development was marked, it could only be detected when a very large number of children with the disorder were included. It is not yet possible to detect such delay from the brain scans of just one individual. The diagnosis of ADHD remains clinical, based on taking a history from the child, the family and teachers."

Been through this before.
