Adult ADHD linked with threefold higher dementia risk

The direction of the association was unclear, the researchers said.

An ADHD diagnosis between the ages of 51 to 70 is associated with a near-threefold higher risk of dementia, a cohort study of 100,000 patients suggests. 

Israeli researchers say adult ADHD could reflect a brain pathobiological process that reduces the body’s ability to compensate for the effects of later-life neurodegenerative and cerebrovascular processes.
