New research published in Neurology (Open Access) shows that self-reported cognitive disability has risen sharply in the United States over the past decade, becoming one of the most significant and fastest-growing public health issues affecting adults of all ages. Cognitive disability in the Behavioral Risk Factor Surveillance System (BRFSS) refers to serious difficulty concentrating, remembering, or making decisions as a result of a physical, mental, or emotional condition. Although this is not the same as a clinical diagnosis of impairment, it captures a meaningful shift in how Americans are experiencing day-to-day cognitive function.
Using more than 4.5 million responses from 2013 to 2023, the study found that age-adjusted prevalence increased from 5.3% in 2013 to 7.4% in 2023. The trend became statistically significant beginning in 2016 and continued rising through 2023. The broad population-level increase was notable, but the most striking aspect of the findings was the dramatic rise among young adults. People aged 18 - 39 saw their prevalence nearly double - from 5.1% to 9.7% - making them the primary drivers of the nationwide increase. This pattern stands in contrast with older adults aged 70 and above, whose rates slightly declined.
These results mark a significant shift in the demographics of cognitive strain. Historically, concerns about cognitive decline have centered on older adults, especially in the context of dementia and age-related impairment. But the new data suggest an emerging trend: younger adults are reporting far more difficulty concentrating, remembering, and making decisions than they did just a decade ago. The causes remain unclear, but the implications span education, workforce stability, mental health services, and the healthcare system at large.
The study also identified substantial racial and ethnic disparities. American Indian and Alaska Native adults consistently had the highest prevalence, reaching more than 11% in 2023. Hispanic adults experienced a steady increase over the decade, reaching 9.9%, while Black adults also saw elevated rates. Asian adults had the lowest and most stable prevalence throughout the study period. These disparities mirror known inequalities in access to care, exposure to structural disadvantages, and the burden of chronic conditions that influence cognitive health.
Socioeconomic factors played a major role as well. Adults with household incomes under $35,000 and those without a high school education reported the highest rates of cognitive disability throughout the decade. In 2023, prevalence for those with less than a high school education reached 14.3%, compared with just 3.6% among college graduates. The association between cognitive disability and low income, unstable employment, and limited education underscores the impact of social determinants of health on cognitive functioning.
Health conditions strongly influenced outcomes. Adults with a history of stroke consistently showed the highest rates, with nearly one in five reporting cognitive disability in 2023. Hypertension, diabetes, and hyperlipidemia were all linked to increased prevalence, aligning with long-established relationships between vascular health and cognitive function. The findings also reinforce that these relationships are likely bidirectional: chronic disease increases cognitive strain, and impaired cognition makes self-management of chronic illness more difficult.
Lifestyle behaviors showed similar patterns. Smoking, physical inactivity, and alcohol use were all associated with higher prevalence, indicating that cognitive disability may reflect broader patterns of health vulnerability. Regional differences also emerged, with the South and Midwest recording higher prevalence than the Northeast and West. U.S. territories reported some of the highest rates overall, suggesting geographic inequalities in healthcare access and economic stability.
One of the study's key methodological decisions was excluding respondents who reported diagnosed depression, allowing researchers to examine cognitive disability independent of mood disorders. Prior research shows that depression and cognitive symptoms reinforce one another, but this study sought to isolate trends unrelated to depressive illness. Even with this exclusion, cognitive disability rose substantially, especially among young adults. This suggests that the increase cannot be explained solely by rising rates of depression or mental health conditions.
The sharp increase among younger adults across all racial, educational, and income groups raises urgent questions. Younger White adults showed the most dramatic rise, with prevalence more than doubling, though younger Black and Hispanic adults also experienced substantial increases. Economic stressors, digital fatigue, changes in work environments, heavier cognitive demands, and post-pandemic effects are all potential contributors, but the study emphasizes that further research is needed to determine the drivers behind the generational shift.
The overall findings highlight a multifaceted public health challenge. Cognitive disability - whether caused by physical conditions, emotional strain, environmental pressures, or lifestyle factors - affects individuals' ability to learn, work, and manage daily responsibilities. By capturing self-reported difficulties rather than clinical diagnoses, the data reflect the lived reality of cognitive strain in modern life. This makes the rising prevalence particularly meaningful for policymakers, educators, healthcare leaders, and employers.
The authors argue that addressing the rise in cognitive disability will require multifactorial strategies, including expanded access to preventive care, culturally appropriate health initiatives, mental health integration, and targeted interventions for chronic disease management. Social determinants - such as stable housing, access to education, food security, and income equality - are likely to be central to any long-term solution.
Through the lens of Seven Reflections' Dimensional Systems Architecture, the rising prevalence of cognitive disability can be viewed as a systemic shift in cognitive load distribution across populations. When environmental, economic, or technological pressures intensify, the cognitive field becomes saturated, disrupting the balance between attention, memory, and decision-making. DSA frames these disruptions not as isolated symptoms but as signals of a system exceeding its structural bandwidth. Younger adults - whose cognitive fields are tightly integrated with digital systems, multitasking demands, and rapid-cycle decision environments - may be experiencing higher field strain, leading to measurable difficulty. This shift suggests a systemic overload rather than isolated deficits, reflecting changes in the conditions under which cognition is required to operate.
