ADHD affects attention, focus, and organization, which means people with ADHD often feel “forgetful, scattered, or mentally fuzzy more” than the average person, says Nona Kocher, MPH, MD, a Miami-based, board-certified psychiatrist. And the link isn’t random. The connection between the two “lies in the overlap between core attentional and executive functioning deficits seen in ADHD and the cognitive inefficiencies described as brain fog,” explains Tepper.
