Scientists are launching a major study to understand why memory loss and dementia affect African people differently than people in Western countries. The research, called FemBER-Africa, will follow 250 African participants and look at how hormones, lifestyle, culture, and genetics influence brain health. By studying blood tests, brain scans, and memory tests designed for African communities, researchers hope to create prevention strategies that actually work for African populations—something that’s been missing from most dementia research so far.

The Quick Take

  • What they studied: How hormones, lifestyle choices, culture, and genetics affect memory loss and dementia risk in African people, especially women
  • Who participated: The study will include 250 African individuals at different stages of memory problems, from healthy to those with dementia
  • Key finding: This is a new study being planned, not yet completed. It will be the first large study to look at how women’s hormones and African ancestry specifically affect dementia risk
  • What it means for you: If you’re an African woman concerned about memory loss, this research may eventually lead to prevention strategies designed specifically for you—not just copied from Western research

The Research Details

The FemBER-Africa project is a new research initiative that will carefully study 250 African participants over time. Researchers will collect blood and saliva samples to look for biological markers of brain health, perform advanced brain scans (MRI and PET scans), and give memory tests that have been adapted for African cultures and languages. The study will compare findings from African participants with data from Western populations to understand what’s unique about dementia risk in African people versus what’s shared across all populations.

This approach is different from most dementia research, which has primarily studied people of European ancestry. By including African participants and looking at factors like hormones during menopause, diet, physical activity, education, and access to healthcare, the study aims to create a complete picture of dementia risk that reflects real African life.

The research is being led by the Brain and Mind Institute at Aga Khan University in Kenya, ensuring that the study is grounded in African communities and understands local contexts.

Most dementia prevention strategies are based on research done in Western countries with mostly white participants. These strategies may not work the same way for African people because of differences in genetics, lifestyle, diet, healthcare access, and cultural factors. By studying African populations directly, researchers can identify what actually causes dementia in these communities and develop prevention methods that actually fit people’s real lives.

This is a well-designed study published in a top dementia research journal. The researchers are using advanced technology (brain imaging and blood biomarkers) combined with culturally appropriate methods. The study is being conducted by established researchers at a respected university. However, this is a research plan, not yet completed results, so we don’t yet have findings to evaluate.

What the Results Show

This study is still in the planning phase and hasn’t produced results yet. The researchers are currently setting up the study and recruiting participants. Once the study is complete, it will provide the first detailed information about how hormones, lifestyle, and genetics specifically affect dementia risk in African populations.

The study will eventually answer important questions like: Do African women’s hormones affect dementia risk differently than Western women’s? Are there specific African ancestry genes that increase or decrease dementia risk? How do diet, physical activity, education, and healthcare access in African communities influence brain health?

When results are published, they will likely show which factors are most important for preventing dementia in African people and which prevention strategies would work best for African communities.

The study will also examine how multiple factors work together—for example, how a woman’s hormone levels combined with her diet and stress level might affect her brain health. It will look at whether factors that increase dementia risk in Western populations have the same effect in African populations. The research will also identify new risk factors that may be specific to African communities.

Most previous dementia research has focused on Western populations, particularly people of European ancestry. This has created a gap in our understanding of dementia in African people. Some smaller studies suggest that African populations may have different dementia risk factors and rates, but large, detailed studies like FemBER-Africa are rare. This research will fill that important gap and help ensure that dementia prevention works for everyone, not just Western populations.

Since this is a research plan rather than completed research, we cannot yet assess limitations of the findings. When the study is completed, important limitations to consider will likely include: the study size (250 people is good but not huge), whether results apply to all African populations or just specific regions, and whether findings can be applied to men as well as women.

The Bottom Line

This research is still being conducted, so there are no new recommendations yet. However, the study’s focus on lifestyle factors (diet, physical activity, education, healthcare access) suggests that these will likely remain important for brain health in African populations. Continue following general brain health advice: stay physically active, eat a healthy diet, stay mentally active, maintain social connections, and get regular healthcare checkups. When FemBER-Africa results are published, they may provide more specific guidance for African populations.

This research is particularly relevant for African women concerned about dementia risk, African healthcare providers, and public health officials in African countries. It’s also important for anyone interested in global health equity and ensuring that medical research serves all populations fairly. The findings will eventually be relevant to anyone of African ancestry worldwide.

This study is currently being set up. Results will likely take several years to produce as researchers recruit participants, collect data, and analyze findings. Expect to see initial findings within 3-5 years, with more detailed results following over the next 5-10 years.

Want to Apply This Research?

  • Track weekly physical activity minutes, daily diet quality (using a simple 1-10 scale), and monthly cognitive activities (like puzzles or learning new skills). This data will help you monitor the lifestyle factors that research suggests may protect brain health.
  • Use the app to set a goal for one lifestyle change: either increasing physical activity to 150 minutes per week, improving diet quality by adding more vegetables and whole grains, or doing 20 minutes of cognitive activities (reading, puzzles, learning) three times per week.
  • Create a monthly brain health scorecard in the app that tracks physical activity, diet quality, cognitive engagement, sleep quality, and stress levels. Review this monthly to see which areas are strong and which need improvement. Share results with your healthcare provider during annual checkups.
