Factors Associated With the Rising Trend in Self-Reported Cognitive Disability Among U.S. Adults Aged 18-39 From 2013-2024.
Article in Annals of clinical and translational neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveBuilding on our prior Behavioral Risk Factor Surveillance System analysis identifying adults aged 18-39 as the primary driver of the national increase in self-reported cognitive disability, we examined factors associated with this rise using 2013-2024 U.S. BRFSS data.
methodsWe analyzed U.S. Behavioral Risk Factor Surveillance System data, excluding 2020 due to poor survey response, to assess trends in self-reported cognitive disability among adults aged 18-39, excluding and including respondents with depression. Cognitive disability was defined as serious difficulty concentrating, remembering, or making decisions due to a physical, mental, or emotional condition. We compared younger adults with versus without cognitive disability across sociodemographic, socioeconomic, health, and mental health characteristics. Analyses incorporated survey weighting to yield U.S. nationally representative estimates.
resultsCognitive disability prevalence increased from 5.1% in 2013 to 9.8% in 2024 (93% increase; p < 0.001). Including respondents with depression, prevalence increased from 10.0% to 17.8% (16.2 million individuals). Among younger adults with cognitive disability, employment increased (55.6% to 65.1%), lack of health insurance declined (35.7% to 19.7%), smoking decreased (28.7% to 14.1%), and physical inactivity decreased (26.9% to 22.3%). Point estimates for hypertension, hyperlipidemia, asthma, diabetes, and stroke prevalence were also lower. In contrast, frequent poor mental health (≥ 14 days/month) increased from 26.6% to 33.2%. In sensitivity analyses excluding depression and any poor mental health days, prevalence still increased from 2.8% to 5.2% (p < 0.001).
interpretationFrom 2013-2024, self-reported cognitive disability among younger United States adults nearly doubled despite improving socioeconomic and cardiometabolic indicators, highlighting a growing burden of perceived or functional cognitive difficulty.
