ADHD Brains Mature Three Years Later
|
Attention deficit hyperactivity disorder delays development of certain regions of the brain by an average of three years, shows a study of 446 youth with and without the disorder.

They found that half of sites in the cortex reached a peak thickness at an average of 10.5 years in children with ADHD compared to 7.5 years in children without the disorder. Meanwhile the motor cortex matured faster in youth with ADHD.
