(Adapted from Making the Connection- A Parent's Guide to Medication in ADHD)
The field of psychiatry is always searching for a conclusive diagnostic test to aid physicians in diagnosing the various mental conditions. Unfortunately this test doesn't currently exist for any psychiatric illness and ADHD is not any different. Brain scans are used frequently in research studies. Research has shown that children with ADHD have smaller brain volumes in specific parts of the brain (frontal lobes, white matter, and cerbellum). These are only research studies and cannot and should not be used to diagnose ADHD in a specific child or teenager.
