ADHD Brain Size

ADHD is one of the most common psychiatric conditions in children. I found studies that children and teens with ADHD have slightly smaller brains (as shown in the picture above) than others without the disorder.This shows us a lot more about ADHD children and teens other than the actual brain size though.

One study was a ten year study from 1991-2001 that was funded by and conducted at The National Institute of Mental Health.
