Black Americans aged 70 and older have a high prevalence of Alzheimer's disease, with over 21% living with this form of dementia, which affects memory, thinking, and behavior1 . Despite this increased risk, Black patients often face significant barriers to timely diagnosis and quality care, leading to worse health outcomes compared to their White counterparts2 . These disparities are influenced by a complex interplay of socioeconomic factors, structural racism, and healthcare system limitations3 .
“Because of structural racism that creates poor access to health, medication, and housing, those who experience racism and discrimination are not provided a pathway to lower their risk.”
— Dr. Carl V. Hill, Alzheimer’s Association9
Black Patient Underrepresentation in Memory Clinics
Black Americans are notably underrepresented in specialty memory clinics, which are critical for early diagnosis and management of Alzheimer’s disease and related dementias (ADRD) 4. Studies show that Black patients are less likely to be referred to these specialty clinics and more likely to present with advanced dementia symptoms when they do seek care5 4. This underrepresentation persists despite Black Americans having a two- to fourfold higher risk of developing ADRD compared to non-Hispanic Whites and experiencing an earlier average age of onset5 .
💡 Did You Know? Among Black Americans ages 70 and older, 21.3% are living with Alzheimer's, a type of dementia that affects memory, thinking, and behavior. Higher rates of cardiovascular disease may play a role1 .
Several factors contribute to this disparity:
- Black patients comprise a smaller proportion of memory clinic attendees than their representation in the local population4 .
- Socioeconomic status and neighborhood characteristics, such as living in disadvantaged areas, are linked to reduced access to specialty dementia care4 .
- Black individuals with dementia are more likely to receive their diagnosis at later stages than White individuals, limiting opportunities for early intervention6 .
These patterns reflect broader systemic issues, including limited healthcare access, mistrust of medical institutions, and cultural beliefs that may delay seeking care7 .
Black patients often face delayed referrals to memory clinics, resulting in more severe symptoms at diagnosis. Socioeconomic and neighborhood disadvantages further limit access to specialized dementia care. 45
Racial Disparities in Alzheimer's Diagnosis and Care
Race-Specific Risk Factors
Black Americans have about twice the prevalence of Alzheimer’s disease and related dementias compared to non-Hispanic Whites among those aged over 65 years6 . Several race-specific risk factors contribute to this elevated risk:
- Higher rates of cardiovascular disease, including hypertension and diabetes, are prevalent among Black populations and may increase dementia risk1 8.
- Chronic stress related to experiences of racism and socioeconomic disadvantage can lead to inflammation, a known risk factor for cognitive decline9 .
- Environmental exposures such as air pollution disproportionately affect disadvantaged communities, further raising dementia risk4 3.
Black patients with Alzheimer’s and related dementias often exhibit greater cognitive impairment and more severe neuropsychiatric symptoms, including delusions, hallucinations, agitation, and irritability, compared to White patients8 . These symptoms may prompt Black older adults to seek medical care later, often when behavioral changes become pronounced, while memory problems are sometimes perceived as a normal part of aging8 .
Community-based interventions and culturally competent care are key to improving Alzheimer’s disease outcomes for Black Americans. Addressing structural racism and socioeconomic barriers is critical for lasting change. 104
Barriers to Diagnosis and Treatment
“To make real progress in achieving equity and closing the gaps in outcomes for Alzheimer’s disease and related dementias, we must do more to ensure the most promising interventions are aimed at those who need them the most.”
— Ana R. Quiñones, Oregon Health & Science University2
Despite their higher risk, Black Americans face significant barriers to receiving an accurate and timely diagnosis of dementia:
- They are less likely to be diagnosed with Alzheimer’s disease in clinical settings and less likely to be referred for neuropsychological testing6 2.
- It takes approximately 11% longer for Black Americans to receive a dementia diagnosis compared to non-Hispanic Whites2 3.
- Black patients are less likely to be prescribed anti-dementia medications such as cholinesterase inhibitors and memantine, and they have higher rates of discontinuing these treatments2 .
- They experience higher rates of hospitalization, longer hospital stays, and increased healthcare costs related to dementia2 .
- Black patients are less likely to receive hospice care and more likely to undergo aggressive life-sustaining treatments, including feeding tubes and mechanical ventilation, during end-of-life care2 9.
- Caregivers of Black Americans with dementia are less likely to complete advanced care directives, which can affect the quality and preferences of care2 .
Structural racism and socioeconomic disadvantages contribute to these disparities by limiting access to quality healthcare, fostering mistrust in medical institutions, and reducing the availability of culturally competent care4 73.
“Reducing disparities in Alzheimer’s disease and related dementias and receiving timely, high-quality health care services is essential to advance health equity.”

Strategies for Equitable Alzheimer's Care Access
Addressing disparities in Alzheimer’s care for Black Americans requires multifaceted strategies targeting systemic barriers and improving community engagement:
- Targeted Education and Outreach: Community-based education programs, including text message campaigns and culturally tailored presentations, can improve Alzheimer’s disease literacy and awareness among Black populations10 .
- Culturally Competent Care: Increasing diversity among healthcare providers and training clinicians in cultural competence can enhance trust and communication with Black patients4 .
- Improved Access to Specialty Clinics: Locating memory clinics in underserved neighborhoods and reducing geographic barriers can facilitate earlier diagnosis and treatment5 4.
- Community Health Workers: Utilizing community health workers to support navigation of healthcare systems and provide culturally relevant support improves access to dementia care for underserved populations4 .
- Addressing Structural Racism: Systemic changes to reduce socioeconomic disadvantages and institutional racism are essential to create equitable pathways for diagnosis, treatment, and support4 3.
