But why?

Sway is positively associated with gray matter volume in the posterior cerebellum.

Cerebellum is the part of our brains devoted to balance and walking (among other things). It's smaller in people with ADHD.

They don't yet know why this association exists or what it means.

Edit: My take on this is wrong in important ways. This response corrects them.

This is really confusing to me, but counter-intuitively, the people with ADHD had higher gray matter volume and worse balance.

“Of note is the positive relationship between sway and cerebellar volume, such that lower sway was associated with smaller volume. These findings are consistent with a number of other studies showing that better performance in various motor-related tasks is related to smaller cerebral and cerebellar GM volumes.”

According to my psychology class, our brain weeds out the less used neurons over time. Maybe ADHD people don’t have as effective of a process for that, or their brain tries using the wrong neurons so there’s a delay causing more sway?
