Study Finds Higher Alzheimer’s Risk Factors Among Low-Income and Minority Groups in U.S.

WASHINGTON — November 20, 2025 — A recent study published Wednesday reveals that individuals from lower-income backgrounds and minority ethnic groups in the United States face a greater accumulation of risk factors associated with Alzheimer’s disease and other dementias, according to researchers.

The study, conducted by a team of public health experts, analyzed data from a nationally representative sample to assess the prevalence of known dementia risk factors across different demographic groups. The findings indicate that economic disadvantage and minority status are linked to a higher burden of conditions and lifestyle factors that contribute to cognitive decline.

Researchers identified several key risk factors more common among low-income and non-white populations, including hypertension, diabetes, smoking, physical inactivity, and lower educational attainment. These factors are known to increase the likelihood of developing Alzheimer’s disease and related dementias, which currently affect millions of Americans.

The study’s authors emphasized the importance of addressing these disparities through targeted public health interventions and policies aimed at reducing socioeconomic and racial inequities. “Our findings underscore the need for tailored strategies to mitigate dementia risk in vulnerable populations,” the report stated.

According to authorities, the disparities in risk factors are influenced by a complex interplay of social determinants of health, including access to healthcare, educational opportunities, neighborhood environments, and economic stability. Minority communities often face systemic barriers that contribute to higher rates of chronic conditions linked to cognitive decline.

Alzheimer’s disease is the most common form of dementia, characterized by progressive memory loss and cognitive impairment. With the U.S. population aging, the number of individuals affected by dementia is expected to rise significantly in the coming decades, placing increased strain on healthcare systems and families.

Experts say that understanding and addressing the root causes of these disparities is critical to reducing the overall burden of dementia. Efforts to improve education, promote healthy lifestyles, and expand access to preventive healthcare could help lower the risk among disadvantaged groups.

The study adds to a growing body of evidence showing that social and economic factors play a crucial role in health outcomes, including neurodegenerative diseases. Public health officials are encouraged to incorporate these findings into broader strategies for dementia prevention and health equity.

While the study highlights significant challenges, it also points to opportunities for intervention. Community-based programs that focus on managing chronic diseases, increasing physical activity, and supporting cognitive health may be particularly beneficial in underserved populations.

The research team called for further studies to explore how targeted policies and interventions can effectively reduce disparities in dementia risk and improve outcomes for all Americans, regardless of income or ethnicity.
