Experts warn of a sharp increase in memory and focus issues among America’s younger adults.

In the last decade, far more U.S. adults under age 40 have begun reporting problems with memory, focus, and decision-making. A new national study found that self-reported cognitive disability nearly doubled between 2013 and 2023. Researchers analyzed millions of survey responses and discovered that what was once seen mostly in older adults is now much more common among younger people. Symptoms like trouble concentrating, forgetfulness, and mental fatigue may be more than simple stress.
