New Study Finds Cognitive Impairment Is Skyrocketing Across America
A major new Neurology study analyzing more than 4.5 million U.S. adults has uncovered a striking trend: self-reported cognitive disability—difficulty concentrating, remembering, or making decisions—has surged by 40% over the past decade.

According to CDC Behavioral Risk Factor Surveillance System (BRFSS) data, prevalence rose from 5.3% in 2013 to 7.4% in 2023, marking the sharpest increase ever recorded.

Even just since 2019, rates climbed from roughly 6.4% to 7.4% nationwide—a 16% jump in only four years. The most dramatic rise occurred among younger adults aged 18–39, where rates nearly doubled, from 5.1% to 9.7%. This climb began around 2016 and continued steadily through 2023, with no signs of stopping.
