Research grant sits at the center of this dementia and brain health question.
Research funding for dementia prevention studies in communities of color is expanding significantly, with the National Institutes of Health, state health departments, and nonprofit organizations allocating millions of dollars to better understand and prevent Alzheimer’s disease and related dementias in Black, Latino, American Indian, and other historically underrepresented populations. A prime example is the April 2026 NIH award of $15.85 million to UC Davis Health and UC San Diego to continue a major study following approximately 1,800 Latino adults over 12 years, using repeated MRI scans, blood biomarker testing, and cognitive assessments to track brain aging and identify protective factors.
This article explores the landscape of research grant programs funding these critical studies, why they exist, what they’re investigating, and how they aim to address a growing dementia crisis that disproportionately affects communities of color. The urgency behind these funding initiatives is clear: the burden of dementia in communities of color is substantially higher than in white populations, yet these communities have historically been underrepresented in research. By examining the data, the funding mechanisms, and the research being conducted, we can better understand both the scope of the problem and the paths forward to prevention and early intervention.

Why Are Research Grant Programs Focusing on Dementia Prevention in Communities of Color?
The statistics paint a stark picture of health disparities. Black Americans are twice as likely to develop Alzheimer’s disease compared to white Americans, while Latino and Hispanic Americans are 1.5 times more likely to develop Alzheimer’s. Among people age 65 and older who are currently dementia-free, the projected lifetime risk of developing dementia is 38% for Black Americans, 35% for American Indians and Alaskan Natives, and 32% for Latinos—all higher than the 27% rate for white older adults. When looking at incidence rates per 1,000 person-years, Black Americans experience 26.6 cases, American Indians and Alaskan Natives 22.2 cases, and Latino and Pacific Islander populations 19.6 cases, compared to 19.3 cases in white populations. These disparities are not random.
They reflect complex interactions between genetic factors, cardiovascular health, access to healthcare, educational opportunities, economic stress, environmental exposures, and chronic conditions like diabetes and hypertension that are themselves more prevalent in communities of color. Funding research specifically in these populations allows scientists to understand both the unique challenges these communities face and the protective factors that might reduce risk. Without targeted research, prevention strategies developed primarily on white populations may miss critical insights or fail to translate effectively across different populations. Federal agencies have recognized this gap, viewing it not just as a research priority but as a public health imperative. By 2030, nearly 40% of all Americans living with Alzheimer’s disease are projected to be Black or Latino, according to current estimates. This projection demands that funding follow the disease burden, directing resources toward understanding and preventing dementia in the communities experiencing the highest rates.
The Federal and State Research Funding Landscape for Dementia Prevention
The NIH has significantly increased its commitment to dementia research funding. For Fiscal Year 2026, the National Institute on Aging allocated $113 million in additional resources specifically for new dementia research, including capacity building for community-engaged Alzheimer’s and related dementias research. This represents a recognition that prevention research must be embedded within communities, partnering with local health systems, community health workers, and trusted institutions rather than treating communities as subjects to be studied from the outside. Beyond the NIH, other organizations are actively funding this work. The California Alzheimer’s Disease Program (ADP) is currently soliciting research proposals to address dementia in communities of color, women, LGBTQ+ communities, and rural areas, with funded projects running from July 1, 2024 through June 30, 2028.
The Alzheimer’s Association’s International Research Grant Program is also open in 2026, supporting investigations into dementia prevention, diagnosis, and care. Additionally, the NIH maintains the Resource Centers for Minority Aging Research (RCMAR), an existing training program that supports diverse and early career scientists conducting research on behavioral and social aspects of aging, health disparities in older adults, and Alzheimer’s disease and related dementias. However, competition for these grants remains fierce—not all proposals receive funding, and many researchers from underrepresented backgrounds still face barriers accessing these opportunities. The scale of investment reflects both the problem’s magnitude and a shift in the research community’s priorities. Fifteen years ago, much less money was directed toward understanding dementia prevention in communities of color. The increase in funding shows growing recognition that prevention research must happen where the burden is greatest.
What Are These Research Programs Actually Studying?
The UC Davis and UC San Diego study provides a concrete example of what modern dementia prevention research looks like in Latino communities. Rather than relying solely on self-reported memory concerns or brief cognitive screening, researchers are collecting biomarkers—actual biological markers in the blood and brain—to detect early brain changes before symptoms appear. The participants are followed longitudinally, meaning the same individuals are tracked over years with repeated assessments, allowing scientists to see how brain changes develop over time and which factors predict who will decline and who will remain cognitively healthy.
This type of research investigates multiple questions simultaneously: Are there Latino-specific genetic risk factors for Alzheimer’s? How do cardiovascular health, diabetes, and depression affect brain aging differently in Latino populations? What protective factors—perhaps related to diet, social engagement, physical activity, or language use—help some individuals resist cognitive decline? Do existing dementia risk prediction tools developed on predominantly white populations perform equally well in Latino populations, or do they miss important warning signs? Preliminary data from this study is expected by 2027, which will help answer these questions. Similar research initiatives are underway or planned for Black and American Indian communities. These studies recognize that dementia prevention is not a one-size-fits-all endeavor; tailored approaches that account for population-specific biology and risk factors are needed for effective prevention strategies.
The Role of Community Engagement and Trust in Research
A critical feature of the newer generation of dementia prevention research in communities of color is genuine community engagement. After decades of research done *to* rather than *with* communities of color—including historical abuses like the Tuskegee Syphilis Study—current funding mechanisms increasingly require that research be embedded in community partnerships. This means collaborating with local health departments, community health centers, churches, senior centers, and trusted community leaders from the start, not simply recruiting participants at the end. This collaborative approach has practical advantages.
Community partners help researchers understand what health concerns people in their communities actually prioritize, what barriers might prevent people from participating in studies (transportation, childcare, mistrust, language), and how to present information in culturally appropriate ways. Research shows that community-engaged studies not only have better retention rates—people stay in the study longer—but also produce findings that are more likely to be believed and adopted by the community when prevention recommendations are ready. The tradeoff is that community-engaged research is slower and more complex than traditional research. It requires additional funding for community partner organizations, time for relationship-building and consensus-seeking, and flexibility to adapt research protocols based on community input. However, for prevention research to ultimately improve health in communities of color, this investment in trust and partnership is essential, not a burden.
Addressing the Underdiagnosis and Diagnostic Disparity Problem
An often-overlooked challenge that funded research is attempting to address is the underdiagnosis of dementia in communities of color. Despite having higher rates of dementia, Black and Latino communities have lower rates of formal dementia diagnosis. This gap creates a paradox: the people at highest risk are least likely to know they have a problem, meaning they miss critical years when early intervention and prevention strategies could help. Multiple factors contribute to this disparity. Some primary care physicians have lower suspicion for dementia in older Black and Latino patients, sometimes attributing cognitive problems to normal aging or educational level.
Language barriers make cognitive screening difficult. Stigma around dementia in some communities makes people reluctant to seek evaluation. And the cognitive screening tools themselves—most developed and validated primarily on white populations—may perform differently across racial and ethnic groups. A warning sign: if prevention research and funding only focus on identifying future cases in currently healthy people, without simultaneously addressing why existing cases go undiagnosed in communities already experiencing high dementia rates, the benefits of prevention efforts will be incomplete. Funded research programs are working to bridge this gap by developing better diagnostic approaches suitable for diverse populations, training diverse clinicians to conduct cognitive assessments, and disseminating evidence-based screening tools more widely in communities of color.
Examples of Research That’s Actually Happening Now
Beyond the UC Davis-UC San Diego Latino Brain Health Study, research programs targeting communities of color are investigating diverse questions. Some studies examine cardiovascular health and dementia prevention, since hypertension, diabetes, and heart disease are more prevalent in communities of color and are established dementia risk factors. Others explore the role of health inequities themselves—whether chronic stress from discrimination, housing instability, or food insecurity accelerates brain aging and dementia risk independently of traditional risk factors.
Research is also emerging on what protective factors might be unique to communities of color. For example, some research suggests that bilingualism may provide cognitive reserve—protective benefits that delay symptom onset even if brain pathology is developing. Studies examining the role of family structure, multigenerational households, spiritual practices, and cultural dietary patterns could reveal prevention strategies that resonate within communities rather than imposing one-size-fits-all approaches developed in other populations.
The Future of Dementia Prevention Research in Communities of Color
As funding continues to increase and more research results emerge—with preliminary data from the major Latino brain health study expected in 2027—the field will face the challenge of translation: moving from research findings to actual prevention interventions available to older adults in communities of color. This will require not just more research funding, but also funding for implementation science, community health worker training, primary care practice change, and health system transformation.
The long-term success of these research investments will be measured not just by publications and grant productivity, but by whether prevention science actually reduces the burden of dementia in communities of color. Building the pipeline of researchers from underrepresented backgrounds—which programs like RCMAR are designed to do—ensures that the leadership of dementia prevention research reflects the communities most affected by it.
Conclusion
Research grant programs funding dementia prevention studies in communities of color represent both a significant shift in research priorities and an acknowledgment of past inequities in how research has been conducted and for whom. With the NIH awarding $15.85 million to track Latino brain aging, state programs soliciting proposals to address dementia in underrepresented communities, and expanded funding for community-engaged research, the infrastructure is in place to finally understand why dementia rates are higher in communities of color and how to prevent it.
The work ahead is substantial. Research results must be translated into real-world prevention programs, diagnostic disparities must be addressed, and clinicians must be trained to provide culturally appropriate dementia care. But for the first time, funding and research attention are proportional to the burden of disease, giving communities of color a real chance at understanding and preventing the dementia epidemic they face.
