Brain Scans & ADHD

Part 2

“A study by F. Xavier Castellanos (NIMH) that supported such an idea [that those with ADHD had a smaller brain size] concluded in its comments the following: "Because almost all (93%) subjects with ADHD had been exposed to stimulants, we cannot be certain that our results are not drug related." Paul Leber, of the Food and Drug Administration has stated, "... as yet, no distinctive pathophysiology for [A.D.H.D.] as a disorder has been delineated."”

“Gene R. Haislip of the Drug Enforcement Administration has stated, "We are also unaware that A.D.H.D. has been validated as a biologic/organic syndrome or disease."”

“James M. Swanson, University of California acknowledged, "I would like to have an objective diagnosis for the disorder (A.D.H.D.). Right now psychiatric diagnosis is completely subjective."”

“F. Xavier Castellanos (National Institute of Mental Health) wrote, "I agree that we have not yet met the burden of demonstrating the specific pathophysiology that we believe underlies this condition."”

“William B. Carey, MD, of the University of Pennsylvania, responded, "There are no such articles constituting proof that A.D.H.D. is a disease or syndrome."”
