Black women face the highest risk of Alzheimer’s disease and related dementias (ADRD) compared to any other racial or gender group in the United States. Research shows that Black adults are two to three times more likely to develop Alzheimer’s than white adults, while women of all races are twice as likely as men to develop the disease. This places Black women at a “vulnerable crossroads,” according to experts.
Risk factors and contributing issues
Socioeconomic and environmental factors
- Chronic stress: A lifetime of exposure to systemic racism, discrimination, and a higher allostatic load (the cumulative “wear and tear” on the body) due to chronic stress may contribute to faster biological aging and increase the risk for Alzheimer’s.
- Neighborhood deprivation: Studies have found an association between living in socioeconomically disadvantaged neighborhoods and a higher incidence of dementia in Black women.
- Health inequities: Higher rates of health conditions like cardiovascular disease, diabetes, and obesity—all known risk factors for Alzheimer’s—are more prevalent in Black women. Systemic health inequities contribute to these disparities.
- Environmental toxins: Research suggests that Black women’s higher exposure to ambient fine particles (
PM2.5cap P cap M sub 2.5𝑃𝑀2.5) may increase their risk for Alzheimer’s disease.
Healthcare barriers
- Bias and discrimination: Black Americans report the highest levels of discrimination in dementia healthcare. This can impact every aspect of care, leading to poor health outcomes.
- Underdiagnosis: Despite their higher risk, Black patients are often diagnosed with dementia later than white patients, if they are diagnosed at all. They are also less likely to be told by a doctor that they have a memory-related disease.
- Medical mistrust: A legacy of racist and unethical medical practices, such as the Tuskegee Experiment, contributes to deep-seated mistrust of the medical system within the Black community. This can prevent or delay individuals from seeking care or participating in research.
- Lack of culturally competent care: Some common cognitive tests have racial biases that can affect the accuracy of diagnoses. This makes it difficult for Black patients experiencing dementia symptoms to get properly diagnosed and treated.
- Socioeconomic constraints: Issues like limited access to reliable transportation and the financial burden of care can make it difficult for Black women to receive consistent care.
Research and clinical trial underrepresentation
- Limited data: Black women are significantly underrepresented in clinical and observational studies for Alzheimer’s, which limits scientific understanding and the ability to generalize findings and new treatments to this at-risk population.
- Lack of trust: Historically, Black communities have been harmed by medical research, which fuels distrust and reduces participation in modern-day trials.
- Implicit bias: Researchers’ reliance on passive, untailored recruitment strategies and their own implicit biases can act as barriers to recruiting Black participants.
Efforts to address disparities
To combat these significant disparities, researchers and organizations are developing more inclusive approaches to Alzheimer’s research and care:
- Community-engaged research: Studies like the Black Women Inflammation and Tau Study (BWITS) are using community-based participatory research models. This involves building partnerships with community members and organizations, incorporating their feedback into study design, and building trust.
- Culturally sensitive outreach: Programs are focusing on creating culturally relevant and accessible educational materials. Organizations like the Alzheimer’s Association are working with community stakeholders and groups, such as churches and professional organizations, to build awareness and trust.
- Provider education: Efforts are underway to improve the cultural competence of healthcare providers and address implicit biases in diagnosis and treatment.
