HealthDay (9/25, Thompson) reports a study found that “a growing number of Americans appear to be losing their brain power, particularly younger adults.” Researchers analyzed CDC survey data collected annually between 2013 and 2023 and observed that the U.S. “experienced a sharp increase in adults experiencing serious problems with memory, concentration and decision-making.” Overall, “the rate of people reporting thinking problems increased from 5.3% in 2013 to 7.4% in 2023, the survey found. For adults under 40, the rate rose sharply from 5.1% to 9.7%, nearly doubling, researchers said. On the other hand, rates among seniors 70 and older declined slightly, from 7.3% to 6.6%.” According to the study, “the biggest increases were found among people who had less education and earned lower wages.” The study was published in Neurology.
