“Challenges with memory and thinking have emerged as a leading health issue reported by U.S. adults,” especially those under 40, according to the author of a new study in the journal Neurology.
A growing number of Americans—especially young adults—are struggling with memory, concentration, and decision-making.
A new study in the journal Neurology finds self-reported cognitive disability rose from about 5% in 2013 to more than 7% in 2023.
The steepest jump was in people ages 18 to 39, where rates nearly doubled to almost 10. By contrast, adults 70 and older actually reported slightly fewer problems.
For the study, researchers analyzed more than 4.5 million survey responses over 10 years. They say economic and social factors played a big role in the results.
Those earning under $35,000 a year or without a high school diploma consistently reported higher rates of cognitive disability.
And while the numbers increased in nearly all racial and ethnic groups, the uptick was largest among American Indian and Alaska Native adults.
The researchers stress their study doesn’t measure clinical impairment—only self-reported struggles. Still, they warn the trend could have lasting effects on public health, workforce productivity, and the U.S. care system.
As for what’s fueling the surge, one author says, “It could reflect actual changes in brain health, better awareness and willingness to report problems, or other health and social factors.”
