Community based sits at the center of this dementia and brain health question.
Community-based participatory research (CBPR) is transforming dementia studies by fundamentally shifting who participates in research and how that research gets conducted. Rather than researchers designing studies and recruiting participants from a distance, CBPR places community members at the table from the very beginning—as partners in identifying research questions, designing methods, collecting data, and interpreting findings. This approach has proven remarkably effective at including people historically underrepresented in dementia research, from rural populations to communities of color, and the results show it works.
A regional CBPR model for Alzheimer’s Disease and Related Dementias operating between November 2021 and April 2025 achieved an average enrollment growth of 2.31 individuals per month, ultimately reaching 97 participants—a significant achievement for rural dementia research where recruitment has traditionally been one of the field’s greatest challenges. What makes CBPR different from conventional research is that it treats the community not as subjects to be studied, but as collaborators whose lived experience and local knowledge are essential to good science. When researchers partner with community advisory boards, participate in long-term community engagement, and develop culturally tailored approaches, they not only recruit more participants—they conduct better research. The insights that emerge are more relevant to the communities they serve, more likely to be implemented in real-world settings, and more likely to address the actual health disparities that communities face rather than questions that only interest academic institutions.

How Community Advisory Boards Ensure Dementia Research Actually Serves the Communities It Studies
At the heart of effective CBPR in dementia research sits the community advisory board—a group of community members, people living with dementia, family caregivers, and local leaders who work alongside researchers throughout the entire study. These boards do far more than rubber-stamp research plans. They ensure that research priorities reflect what communities actually need, that study designs are feasible within real-world constraints, and that findings get translated into actionable changes rather than sitting in academic journals. For communities historically excluded from dementia research—particularly Latino communities and rural populations—community advisory boards have become the mechanism that makes inclusive research possible. The difference this makes is substantial. Research with established community advisory boards shows that participant preferences and needs are genuinely integrated into study design, not added as an afterthought.
These boards catch problems that outside researchers would miss: cultural misunderstandings, recruitment barriers rooted in historical trauma with medical institutions, logistical challenges like lack of transportation, or language needs. When a community advisory board identifies these issues early, researchers can design studies that work for the community from the start. Without this partnership, studies fail to recruit adequately or collect data that reflects community realities. However, building effective community advisory boards requires genuine investment. This isn’t a one-meeting-per-year arrangement. Effective boards require ongoing compensation for community members’ time and expertise, regular communication, and a willingness from researchers to actually listen when communities push back on proposed research directions. Many researchers approach this as an obligation they’d prefer to minimize, which quickly becomes obvious to communities and undermines trust.
The Core Elements That Make CBPR Work in Dementia Studies
Successful CBPR in dementia research relies on a specific set of practices that have proven effective across different settings and populations. Long-term community engagement is the foundation—relationships built over months and years, not weeks. Culturally tailored education that translates complex dementia research concepts into language and frameworks that make sense within specific communities. Participatory methods that involve community members in every phase from research question development through data interpretation. And logistical support that removes barriers to participation: transportation, childcare, accessible meeting spaces, stipends for participation. What’s notable is that these elements work across diverse contexts. rural communities, urban communities of color, immigrant communities—when researchers commit to these practices, enrollment and retention improve.
The regional CBPR model for Alzheimer’s disease in rural communities didn’t succeed because participants suddenly became more available; it succeeded because the program built in transportation support, met at times and places convenient to rural communities, and worked through trusted local organizations rather than approaching people cold. One significant limitation of CBPR, however, is that it’s slower and more resource-intensive than conventional research. Reaching consensus with a community advisory board takes time. Developing culturally tailored education materials requires expertise and iteration. Providing logistical support adds real costs to research budgets. Some researchers and institutions resist CBPR precisely because it demands more time and resources upfront. Yet research shows that this investment pays dividends in better enrollment, higher retention, more meaningful findings, and greater likelihood of real-world implementation—but funders and institutions need to understand and value these returns.
Addressing Rural Underrepresentation in Dementia Research Through CBPR
For decades, dementia research has been concentrated in urban academic centers, leaving rural communities substantially underrepresented in the evidence base. Rural areas face distinct challenges: fewer neurologists and specialists, limited access to clinical trial sites, geographic isolation, and distinct cultural contexts where medical mistrust may run particularly deep due to historical inequities. CBPR offers a pathway to change this by designing research that fits rural realities rather than asking rural communities to fit into urban research models. The regional CBPR model operated specifically to address rural underrepresentation, and it was designed with rural contexts in mind from the start. Rather than assuming rural residents would travel to distant research sites, the program brought research into communities through partnerships with local health organizations.
Rather than using recruitment methods that work in cities, the program worked with trusted community leaders who understood local networks and had existing relationships. This tailoring to rural social, cultural, and geographic contexts proved essential to reaching 97 participants over the program’s timeline. The tradeoff here is scalability versus contextualization. A CBPR approach tailored to one rural community may not transfer directly to another rural region fifty miles away with different demographics, economic conditions, and cultural composition. This means that expanding CBPR approaches to address rural underrepresentation requires building similar partnerships in each new setting—more work than launching a standardized protocol, but the alternative is continuing to conduct dementia research without rural voices and perspectives.
Creating Pathways for Inclusive Dementia Research Through Public and Participant Involvement
Recent research in 2025 validates what practitioners have been learning: public and participant involvement is a direct pathway to achieving more inclusive dementia research. This goes beyond simply recruiting diverse participants to include involving people living with dementia themselves in shaping research agendas. When people with dementia and their families have input into what gets studied, how it gets studied, and how findings get communicated, the resulting research is more responsive to the realities they actually face. The practical implementation of this requires systematic structures. Patient advisory groups, public involvement events where community members help identify research priorities, participatory workshops where people with dementia and caregivers engage directly in study design.
Unlike traditional “patient engagement” that often amounts to giving people information after decisions are made, genuine public and participant involvement means reconsidering research direction when communities raise important concerns. It means prioritizing research questions that communities identify as important rather than only pursuing questions that researchers find academically interesting. The comparison worth noting is between research that consults communities and research that genuinely partners with them. Consultation happens after decisions are mostly made; partnership means communities share decision-making power from the beginning. Many institutions claim to do public involvement but are primarily doing consultation, which explains why communities sometimes feel their input didn’t actually change anything. True partnership requires openness to significantly shifting research direction based on community input.
Navigating the Challenge of Sustaining Community Engagement in Long-Term Dementia Studies
One of the most significant challenges in CBPR dementia research is maintaining genuine community engagement throughout the life of the study. Research studies take years. Community advisory board members move, face health challenges, or exhaust their willingness to volunteer time indefinitely. Community organizations shift priorities. The initial energy and enthusiasm of community partners can wane if they perceive that their input isn’t actually shaping research direction or if the benefits of participation aren’t visible to them. There’s also a risk of community engagement becoming performative—researchers going through the motions of convening advisory boards and conducting focus groups while continuing to make all meaningful decisions behind closed doors.
Communities can sense this misalignment quickly. Once trust erodes, rebuilding it becomes extremely difficult, and recruitment and retention suffer. This is why sustained funding specifically for community partnership—not just for the research itself—is essential. Community members should be compensated for their time, not as a token honorarium but at rates that reflect the value of their expertise. Another warning worth noting: CBPR works best when there’s genuine humility from researchers about what they don’t know. If researchers approach communities with the attitude that they’ve already figured out the right approach and just need community members to help them implement it, CBPR becomes extractive regardless of its intentions. The research that actually improves through CBPR is research where the research team is genuinely open to communities identifying different priorities, different approaches, and different interpretations of what the findings mean.
Dementia-Friendly Communities and Dialogical Community Development
Beyond research participation itself, recent advances in dialogical community development offer a complementary approach to making dementia research and dementia services more inclusive. Rather than research centered narrowly on clinical outcomes or interventions, dialogical community development engages people living with dementia in shaping what dementia-friendly communities actually look like. This has expanded how researchers think about meaningful outcomes—moving beyond cognitive decline measurements to consider quality of life, social inclusion, community participation, and what kind of life a person with dementia can actually live.
Dementia-friendly communities that apply these principles report improved engagement from people living with dementia. Community members participate more actively in identifying barriers to inclusion, suggesting solutions, and shaping how communities respond to dementia. This is research that doesn’t just study people; it empowers them to shape the communities they live in. The distinction matters—it moves from the question “how can we get people with dementia to fit into our existing systems” to the more fundamental question “how should our communities change so everyone, including people with dementia, can participate fully.”.
The Future of Inclusive Dementia Research and What Comes Next
The trajectory is clear: dementia research is moving toward greater community partnership and inclusion. What was once considered a nice add-on—having community members involved in research—is increasingly understood as essential to conducting valid, relevant science. Funders are beginning to require evidence of community engagement in grant proposals. Journals are more likely to publish research that demonstrates genuine participatory involvement. This represents a fundamental shift in what counts as good research.
Looking forward, the challenge is scaling these approaches without losing their essential ingredient: genuine partnership. As CBPR models become more established, there’s risk they become routinized, stripped of the authentic engagement that makes them work. The regional CBPR model for rural Alzheimer’s disease succeeded not because community engagement was easy or quick, but because researchers committed to doing it well. Replicating that success in other rural areas and other communities requires matching that commitment. The future of inclusive dementia research depends on whether the field can sustain this investment beyond the initial enthusiasm.
Conclusion
Community-based participatory research has demonstrated concrete capacity to make dementia studies more inclusive. By positioning community members as partners rather than subjects, establishing community advisory boards with genuine decision-making authority, providing logistical support to remove barriers to participation, and committing to long-term engagement, research programs can reach people historically absent from dementia research. The evidence is accumulating: rural regions, communities of color, people living with dementia and their families—all participate at higher rates and contribute richer data when research is designed with them rather than for them. The practical path forward for dementia researchers and institutions is clear: invest in community partnership not as a compliance requirement but as a core research function.
Compensate community members appropriately for their expertise. Build in time and flexibility for genuine collaborative work. Be prepared for community input to actually change research direction. The studies that take this approach are more rigorous, more relevant, and more likely to produce findings that communities can actually use to improve dementia care and support.
