Vascular Dementia in the US 2025
Vascular dementia stands as the second most common form of dementia in the United States, affecting millions of Americans and representing a significant yet potentially preventable public health challenge. This condition results from reduced blood flow to the brain, caused by damaged or blocked blood vessels that deprive brain tissue of essential oxygen and nutrients. Recent epidemiological data from the American Heart Association indicates that approximately 2.7 million individuals are currently living with vascular dementia or mixed dementia with a vascular contribution, though healthcare billing records identify only 809,000 people with formal diagnoses, revealing a substantial gap in recognition and diagnosis of this condition across the nation.
The pathways leading to vascular dementia are diverse, ranging from major strokes that cause sudden cognitive decline to small vessel disease that produces gradual deterioration over years. Understanding the full scope of this condition requires examining not only those with clinical diagnoses but also the millions of Americans living with silent cerebrovascular disease that may eventually manifest as cognitive impairment. In 2020, an estimated 11.3 million people had covert brain infarcts, 11.1 million had high volumes of white matter hyperintensity, and 19.9 million had cerebral microbleeds potentially detectable by magnetic resonance imaging. These subclinical markers represent a vast reservoir of individuals at elevated risk for future cognitive decline, emphasizing the critical importance of vascular risk factor management throughout the lifespan for brain health preservation.

The disparity between diagnosed and estimated cases of vascular dementia represents one of the most striking findings in recent epidemiological research. While healthcare billing data identifies 809,000 Americans with formal vascular dementia diagnoses, epidemiological studies suggest the true number approaches 2.7 million individuals when including mixed dementia with vascular contributions. This three-fold difference highlights the significant underdiagnosis problem in clinical settings. Annual incidence data reveals a similar pattern, with billing records documenting 102,000 new diagnoses yearly while epidemiological estimates suggest 603,000 new cases actually occur. Among Medicare beneficiaries specifically, vascular dementia accounts for 14.5% of all dementia cases, with a prevalence rate of 2.1 per 100 beneficiaries documented between 2011 and 2013.
Perhaps even more concerning is the prevalence of subclinical cerebrovascular disease in the American population. An estimated 11.3 million people have covert brain infarcts that have not produced obvious clinical symptoms but still indicate brain tissue damage. Another 11.1 million individuals have elevated white matter hyperintensity volumes detectable on magnetic resonance imaging, representing small vessel disease damage. Additionally, 19.9 million people have cerebral microbleeds, tiny areas of bleeding in brain tissue that increase risk for both future stroke and cognitive decline. These subclinical markers far exceed the number of people with formal vascular dementia diagnoses, representing a massive at-risk population. The incidence rate among individuals aged 70 years and older ranges from 6 to 12 per 1,000 persons per year, while prevalence in those aged 65 and older ranges from 1.2% to 4.2% depending on the population studied. The mean disease duration from diagnosis is approximately 5 years, though individual trajectories vary considerably.
Prevalence and Incidence of Vascular Dementia in the US 2024

Data sources: American Heart Association Scientific Statement (2025), Medicare claims analysis (2011-2013), Population-based cohort studies
The prevalence and incidence data for vascular dementia in the United States reveals substantial burden across the older adult population. The diagnosed prevalence of 809,000 cases based on healthcare billing records dramatically underestimates the true burden compared to the epidemiologically estimated 2.7 million individuals living with vascular dementia or mixed dementia with vascular contributions. This more than three-fold difference between diagnosed and actual cases suggests that the majority of individuals with vascular dementia remain unrecognized in clinical practice, potentially missing opportunities for appropriate management and risk factor modification. Among those aged 65 years and older, population-based studies show prevalence ranging from 1.2% to 4.2%, with variation across different geographic regions and study methodologies reflecting both true differences and diagnostic challenges.
The Medicare population shows a prevalence rate of 2.1 per 100 beneficiaries, with vascular dementia accounting for 14.5% of all diagnosed dementia cases among Medicare recipients. Annual incidence figures similarly demonstrate the gap between diagnosed cases (102,000 new diagnoses) and epidemiologically estimated new cases (603,000 annually). Among individuals aged 70 years and older, the incidence rate ranges from 6 to 12 cases per 1,000 person-years, translating to substantial numbers of new cases each year as the population ages. These statistics underscore that vascular dementia represents a major public health burden that extends far beyond what clinical diagnostic records capture, with millions of Americans affected either by diagnosed disease or by subclinical cerebrovascular pathology that places them at high risk for future cognitive decline.
Age Distribution of Vascular Dementia in the US 2024
| Age Group | Prevalence/Incidence Pattern | Clinical Significance |
|---|---|---|
| Under 65 years | Rare occurrence | Younger onset uncommon |
| 65-74 years | 5.0% dementia prevalence | Lower risk group |
| 75-84 years | Rising prevalence | Accelerating risk |
| 85 years and older | 37.4% dementia prevalence | Highest risk group |
| 71-79 years | 5.0% overall dementia | Includes vascular subtype |
| 90 years and older | 37.4% overall dementia | Peak prevalence period |
| Age-Specific Incidence | Increases 9-10% per year of age | Linear increase with age |
Data sources: Aging, Demographics, and Memory Study (ADAMS), American Heart Association population data, Longitudinal cohort studies
The age distribution of vascular dementia in the United States demonstrates a clear and dramatic pattern of increasing prevalence with advancing age. Among younger individuals under 65 years, vascular dementia is relatively rare, though it can occur particularly in those with significant vascular risk factors or genetic conditions affecting blood vessels. The prevalence of all dementia, including vascular dementia, stands at 5.0% among individuals aged 71-79 years, representing the beginning of the steep age-related increase in risk. As individuals move into their eighties, prevalence accelerates substantially, and by age 85 and older, a remarkable 37.4% of the population has some form of dementia, with vascular dementia representing a significant proportion of these cases.
The age-specific incidence of stroke and cerebrovascular disease, which drive vascular dementia risk, increases by approximately 9% per year of age in men and 10% per year of age in women, reflecting the cumulative impact of lifetime vascular damage and age-related arterial changes. The population aged 90 years and older shows the highest prevalence at 37.4%, representing the peak period for diagnosis. This age distribution pattern has important implications for healthcare planning, as the rapidly growing population of Americans aged 85 and older will drive substantial increases in vascular dementia cases in coming decades unless effective prevention strategies are widely implemented. The linear increase in risk with each year of aging emphasizes the importance of lifelong vascular risk factor management, as damage accumulates progressively throughout the life course.
Gender and Sex Differences in Vascular Dementia in the US 2024
| Gender Factor | Finding | Clinical Pattern |
|---|---|---|
| Male Incidence | Higher in younger ages | Rate ratio 1.6 (not significant) |
| Female Incidence | Comparable or higher in older ages | Adjusted rate ratio 0.57 |
| Percentage in Men | 15.3% of dementia cases | Vascular subtype proportion |
| Percentage in Women | 14.0% of dementia cases | Vascular subtype proportion |
| Age-Related Pattern | Gender differences emerge after age 80 | Later life distinction |
| White Matter Lesions | More common in women | Associated with female gender |
| Stroke Prevalence | Approximately equal by sex | Similar numbers affected |
| Lifetime Stroke Risk | Higher in women | Greater cumulative risk |
Data sources: Rotterdam Study, American Heart Association data, Gender-specific epidemiological analyses
Gender and sex differences in vascular dementia present a complex pattern that varies by age and specific cerebrovascular pathology. Population-based studies such as the Rotterdam Study found that men had a higher age-adjusted incidence of vascular dementia compared to women, with a rate ratio of 1.6, though this difference did not reach statistical significance. However, after adjustment for other risk factors, women actually showed lower incidence with a rate ratio of 0.57 compared to men. Among diagnosed dementia cases, vascular dementia accounts for 15.3% of cases in men compared to 14.0% in women, suggesting slightly higher representation in males though the difference is modest.
The pattern of gender differences varies significantly by age, with distinctions becoming more prominent after age 80 in studies conducted in the United States. White matter lesions, a key pathological substrate of subcortical vascular dementia, show correlation with female gender along with advancing age and vascular risk factors including hypertension and diabetes. Despite approximately equal stroke prevalence by sex in terms of absolute numbers, women face higher total lifetime stroke risk and poorer stroke outcomes compared to men. Approximately half of all individuals affected by stroke each year are women, who represent a substantial proportion of the vascular dementia population. These gender-specific patterns likely reflect complex interactions between biological factors (hormones, vascular remodeling patterns), behavioral factors (historical differences in smoking, physical activity), and social determinants of health (educational attainment, healthcare access), all of which influence both cerebrovascular disease risk and subsequent cognitive outcomes.
Post-Stroke Dementia Risk in the US 2024
| Risk Factor | Magnitude | Time Period |
|---|---|---|
| Overall Dementia Risk After Stroke | 80% higher risk | Compared to general population |
| First Year After Stroke | Nearly 3-fold (300%) increased risk | Peak risk period |
| Five Years After Stroke | 1.5-fold (150%) increased risk | Declining but elevated |
| Twenty Years After Stroke | Elevated risk persists | Long-term effect |
| Hemorrhagic Stroke Risk | 150% higher dementia risk | Worse than ischemic |
| Stroke vs. Heart Attack | 80% higher dementia risk | Compared to MI survivors |
| Post-Stroke Dementia Prevalence | 19% develop dementia | Over 6-year follow-up |
| Stroke Survivors Developing Dementia | About 1 in 4 (25%) | Population estimate |
Data sources: Canadian population study (2024), American Heart Association International Stroke Conference (2024), CDC surveillance data
The relationship between stroke and subsequent vascular dementia development is extraordinarily strong and well-documented in recent research. Individuals who experience stroke face an 80% higher risk of developing dementia compared to the general population, even after accounting for other dementia risk factors such as hypertension, diabetes, and high cholesterol. The risk elevation is most dramatic in the first year following stroke, when survivors face a nearly three-fold (300%) increased risk for dementia compared to peers who have not had strokes. This acute elevation reflects the immediate impact of brain tissue damage on cognitive reserve and function.
Over time, the magnitude of elevated risk gradually declines but remains substantially higher than baseline for decades. By five years after stroke, the risk has decreased to approximately 1.5-fold (150%) increased compared to those without stroke history, and even at twenty years after the initial event, risk remains measurably elevated. Hemorrhagic strokes (bleeding in the brain) confer particularly high risk, with a 150% increased risk of dementia compared to the general population. Stroke survivors also face higher dementia risk than heart attack survivors, with an approximately 80% higher risk compared to those with myocardial infarction. Population data shows that approximately 19% of stroke survivors develop dementia over an average six-year follow-up period, translating to roughly 1 in 4 individuals (25%) who experience stroke eventually developing signs of dementia. These sobering statistics underscore the critical importance of stroke prevention through vascular risk factor management and highlight the need for ongoing cognitive monitoring among stroke survivors.
Mortality Rates for Vascular Dementia in the US 2022
| Mortality Metric | Rate/Number | Population | Year |
|---|---|---|---|
| Total Dementia Deaths (65+) | 288,436 deaths | Adults 65 and older | 2022 |
| Overall Dementia Death Rate | 548.9 per 100,000 | Age-adjusted | 2022 |
| Male Dementia Death Rate | 464.6 per 100,000 | Age-adjusted males | 2022 |
| Female Dementia Death Rate | 599.6 per 100,000 | Age-adjusted females | 2022 |
| Death Rate Increase (2019-2020) | 10.2% increase | All dementia types | 2019-2020 |
| 2020 Peak Death Rate | 572.9 per 100,000 | Age-adjusted | 2020 |
| Vascular Dementia Survival | Less than general population | VaD patients | Multiple studies |
| Mean Disease Duration | Approximately 5 years | From diagnosis | Clinical data |
Data sources: CDC National Vital Statistics System (2022), National Center for Health Statistics mortality files, Dementia mortality reports
Mortality data for vascular dementia is captured within broader dementia death statistics reported by the Centers for Disease Control and Prevention. In 2022, a total of 288,436 deaths among U.S. adults aged 65 and older were attributed to dementia as the underlying cause of death, encompassing vascular dementia, Alzheimer’s disease, unspecified dementia, and other neurodegenerative conditions. The overall age-adjusted dementia death rate reached 548.9 per 100,000 population in 2022. Gender differences in mortality are substantial, with females showing a higher death rate of 599.6 per 100,000 compared to males at 464.6 per 100,000, reflecting both higher prevalence and longer survival with disease in women.
Between 2019 and 2020, dementia death rates increased dramatically by 10.2%, rising from 520.1 per 100,000 to a peak of 572.9 per 100,000 in 2020, largely attributed to the impact of the COVID-19 pandemic on individuals with dementia who were particularly vulnerable to severe outcomes from infection. Survival data specific to vascular dementia indicates that affected individuals experience shorter survival compared to the general population, with a mean disease duration of approximately 5 years from diagnosis. This survival is generally less favorable than some other dementia subtypes, reflecting both the impact of cognitive decline and the ongoing burden of underlying cerebrovascular disease that continues to cause recurrent vascular events. The mortality burden of vascular dementia extends beyond direct causes to include complications such as pneumonia, falls, and cardiovascular events that are more common in this population due to both cognitive impairment and systemic vascular disease.
Risk Factors for Vascular Dementia in the US 2024
| Risk Factor | Impact Magnitude | Evidence Strength |
|---|---|---|
| Hypertension | Major modifiable risk factor | Very strong evidence |
| Diabetes Mellitus | Substantially increases risk | Strong evidence |
| Heart Disease | Significant risk elevation | Strong evidence |
| Prior Stroke | 80% to 300% increased risk | Very strong evidence |
| Atrial Fibrillation | Cardioembolic stroke risk | Strong evidence |
| Hyperlipidemia | Atherosclerosis contribution | Moderate evidence |
| Smoking | Vascular damage mechanism | Strong evidence |
| Obesity | Multifactorial risk increase | Moderate evidence |
| Physical Inactivity | Modifiable lifestyle factor | Moderate evidence |
| Age (Increasing) | Primary non-modifiable factor | Very strong evidence |
Data sources: American Heart Association guidelines, INTERSTROKE study, Lancet Commission on Dementia Prevention (2024), CDC risk factor data
The risk factors for vascular dementia are largely modifiable conditions affecting cardiovascular health, offering substantial opportunity for prevention. Hypertension stands as one of the most important modifiable risk factors, with elevated blood pressure throughout midlife and late life causing damage to blood vessels in the brain including both large vessels and the small penetrating arteries that supply deep brain structures. Diabetes mellitus substantially increases vascular dementia risk through multiple mechanisms including damage to small blood vessels (microangiopathy), increased inflammation, and acceleration of atherosclerosis. Heart disease, including coronary artery disease and heart failure, contributes to reduced cerebral perfusion and increases risk for embolic strokes that can cause cognitive impairment.
Prior stroke represents perhaps the single strongest risk factor, increasing dementia risk by 80% to 300% depending on time since the event, with the highest elevation in the first year following stroke. Atrial fibrillation, an irregular heart rhythm affecting millions of Americans, substantially increases risk for cardioembolic strokes that can lead to vascular dementia. Hyperlipidemia promotes atherosclerosis throughout the vascular system including cerebral arteries, while smoking directly damages blood vessel walls and promotes thrombosis. Obesity and physical inactivity increase risk through multiple pathways including effects on blood pressure, glucose metabolism, lipid profiles, and inflammation. Advanced age remains the strongest non-modifiable risk factor, with incidence increasing approximately 9-10% with each year of age. The 2024 Lancet Commission on Dementia Prevention estimates that up to 45% of dementia risk is potentially preventable through modification of these and other lifestyle and health factors, suggesting enormous potential for reducing the burden of vascular dementia through population-level risk factor control.
Subclinical Cerebrovascular Disease in the US 2020
| Subclinical Marker | Prevalence | Population Affected |
|---|---|---|
| Covert Brain Infarcts | 11.3 million people | U.S. adults |
| White Matter Hyperintensity (High Volume) | 11.1 million people | U.S. adults |
| Cerebral Microbleeds | 19.9 million people | U.S. adults |
| Total with Subclinical Markers | Millions at risk | Overlapping populations |
| Silent Infarcts (General) | Common in older adults | Age-related increase |
| White Matter Disease | Correlates with vascular risk | Hypertension, diabetes |
| MRI-Detectable Pathology | Often asymptomatic | Requires imaging to identify |
Data sources: American Heart Association Scientific Statement (2025), Population-based neuroimaging studies, Framingham Heart Study, ARIC Study
One of the most significant findings in recent vascular dementia research is the enormous burden of subclinical cerebrovascular disease in the American population. An estimated 11.3 million individuals have covert brain infarcts that are detectable on magnetic resonance imaging but have not produced clinically apparent stroke symptoms. These silent infarcts represent areas of permanently damaged brain tissue that accumulate over time and progressively erode cognitive reserve. An additional 11.1 million people have high volumes of white matter hyperintensity visible on brain imaging, reflecting damage to the white matter tracts that connect different brain regions and are essential for efficient neural communication.
Perhaps most strikingly, 19.9 million Americans have cerebral microbleeds, tiny areas of bleeding in brain tissue caused by small vessel disease. While individually these microbleeds may produce no symptoms, their accumulation over time increases risk for both larger hemorrhagic strokes and progressive cognitive decline leading to vascular dementia. These subclinical markers often coexist in the same individuals, creating a cumulative burden of cerebrovascular pathology. The markers correlate strongly with vascular risk factors particularly hypertension and diabetes, emphasizing the lifelong impact of these conditions on brain health. The fact that tens of millions of Americans harbor these subclinical markers, far exceeding the number with diagnosed vascular dementia, represents an enormous reservoir of at-risk individuals who could potentially benefit from intensified vascular risk factor management to prevent progression to clinical dementia. This subclinical burden underscores that vascular dementia represents merely the tip of the iceberg of vascular brain injury affecting the American population.
Comorbidities Associated with Vascular Dementia in the US 2024
| Comorbidity | Prevalence in VaD | Clinical Relationship |
|---|---|---|
| Hypertension | Very high prevalence | Primary vascular risk factor |
| Diabetes Mellitus | Common comorbidity | Microangiopathy contributor |
| Hyperlipidemia | Frequent occurrence | Atherosclerosis mechanism |
| Coronary Artery Disease | Common co-occurrence | Shared vascular pathology |
| Atrial Fibrillation | Significant proportion | Embolic stroke mechanism |
| Chronic Kidney Disease | Associated condition | Shared vascular damage |
| Obstructive Sleep Apnea | Increasingly recognized | Hypoxia and vascular effects |
| Depression | High prevalence | Vascular depression syndrome |
Data sources: Clinical registries, Population-based cohort studies, American Heart Association analyses
Individuals with vascular dementia typically present with substantial burden of coexisting medical conditions, reflecting the systemic nature of vascular disease. Hypertension is nearly universal among vascular dementia patients, present in the vast majority of cases and representing both a causal factor and ongoing management challenge. The same arterial changes that damage brain blood vessels affect vessels throughout the body, leading to high rates of coronary artery disease, with many patients having experienced myocardial infarction or having chronic ischemic heart disease. Diabetes mellitus is extremely common in the vascular dementia population, contributing to disease through damage to small blood vessels (diabetic microangiopathy) that affects both the brain and other organs.
Hyperlipidemia frequently coexists, promoting atherosclerotic plaque formation in large arteries including the carotid arteries supplying the brain. Atrial fibrillation affects a significant proportion of vascular dementia patients, serving as a major mechanism for embolic strokes that can precipitate or worsen cognitive decline. Chronic kidney disease shares many of the same vascular risk factors and pathological processes affecting small blood vessels, making it a common comorbidity. Obstructive sleep apnea is increasingly recognized as both a risk factor for vascular dementia through intermittent hypoxia and its effects on blood pressure and cardiovascular health. Depression shows particularly high prevalence in vascular dementia patients, with evidence suggesting that vascular changes in brain circuits regulating mood contribute to what has been termed “vascular depression.” The high burden of comorbidities necessitates comprehensive medical management addressing multiple systems simultaneously, making care coordination essential for optimizing outcomes in this complex patient population.
Healthcare Costs and Economic Burden of Vascular Dementia in the US 2024
| Cost Category | Estimated Impact | Contributing Factors |
|---|---|---|
| Direct Medical Costs | Substantial per patient | Hospitalizations, outpatient care |
| Hospitalization Costs | Primary cost driver | Stroke, complications, comorbidities |
| Outpatient Care Costs | Ongoing expenses | Physician visits, specialists |
| Medication Costs | Moderate component | Vascular risk factor management |
| Long-term Care Costs | Major burden | Nursing home, assisted living |
| Informal Caregiving | Enormous societal cost | Family caregiver time |
| Lost Productivity | Indirect economic impact | Patient and caregiver work loss |
| Emergency Department Visits | Frequent utilization | Falls, acute complications |
Data sources: Healthcare utilization studies, Economic analyses of dementia burden, Medicare cost data
The economic burden of vascular dementia in the United States is substantial, encompassing both direct medical costs and enormous indirect costs borne by families and society. Direct medical costs are driven primarily by hospitalizations, which occur frequently due to recurrent strokes, falls resulting from gait impairment and cognitive deficits, infections particularly pneumonia and urinary tract infections, and acute complications of comorbid conditions. Patients with vascular dementia require extensive outpatient medical care including regular visits with primary care physicians, neurologists, cardiologists, and other specialists, along with allied health services such as physical therapy, occupational therapy, and speech therapy.
Long-term care costs represent one of the largest components of the economic burden, as many individuals with vascular dementia eventually require nursing home placement or extensive home health services due to the combination of cognitive impairment, physical disability from stroke, and complex medical needs. Medication costs include drugs to manage vascular risk factors (antihypertensives, statins, antiplatelet agents, anticoagulants), along with symptomatic treatments for behavioral and psychological symptoms. Perhaps the largest component of economic burden comes from informal caregiving, with family members providing thousands of hours of unpaid care annually to individuals with vascular dementia, representing enormous societal costs when valued at replacement wage rates. Lost productivity affects both patients (who often must retire early) and family caregivers (who may reduce work hours or leave employment entirely), creating additional indirect economic impacts. The preventable nature of much vascular dementia suggests that investments in vascular risk factor control throughout the lifespan could yield substantial economic returns by reducing disease incidence and the associated healthcare and societal costs.
Racial and Ethnic Disparities in Vascular Dementia in the US 2024
| Racial/Ethnic Group | Risk Pattern | Contributing Factors |
|---|---|---|
| Black/African American | Higher dementia risk | Greater vascular risk factor burden |
| Hispanic/Latino | Elevated risk | High diabetes, hypertension rates |
| White/Caucasian | Lower relative risk | Better vascular risk factor control |
| Asian American | Variable patterns | Heterogeneous population |
| American Indian/Alaska Native | Higher risk | Greater modifiable risk factor burden |
| Modifiable Risk Factor PAF (Black) | Higher than White | Greater preventable fraction |
| Modifiable Risk Factor PAF (Hispanic) | Higher than White | Greater preventable fraction |
| Vascular Risk Factor Prevalence | Varies substantially by race/ethnicity | Reflects health disparities |
Data sources: American Heart Association population analyses, Health disparities research, CDC WONDER demographic data
Substantial racial and ethnic disparities exist in vascular dementia risk across the United States, largely reflecting differences in vascular risk factor prevalence and control. Black and African American individuals face higher dementia risk overall, with vascular contributions playing a significant role due to disproportionately high rates of hypertension, diabetes, stroke, and obesity in this population. Studies examining the population attributable fraction of modifiable risk factors for dementia consistently find higher fractions in Black populations compared to White populations, indicating that a greater proportion of dementia cases could potentially be prevented through risk factor modification in these communities.
Hispanic and Latino Americans similarly show elevated vascular dementia risk, correlating with high prevalence of diabetes and hypertension particularly affecting this population. White/Caucasian individuals generally show lower relative risk, though absolute numbers of affected individuals remain high due to the large size of this demographic group and better population-level control of vascular risk factors. American Indian and Alaska Native populations face particularly high risk due to extremely high rates of diabetes and other modifiable vascular risk factors, combined with healthcare access barriers. Asian American populations show variable patterns reflecting the heterogeneous nature of this group, with some subpopulations facing elevated risk while others show lower rates. These disparities are not primarily biological in origin but rather reflect complex interactions between social determinants of health including healthcare access, insurance coverage, health literacy, discrimination experiences, residential segregation patterns affecting environmental exposures, and cumulative lifetime disadvantage affecting stress and health behaviors. Addressing racial and ethnic disparities in vascular dementia requires comprehensive efforts to reduce disparities in vascular risk factor prevalence and improve equity in access to preventive care and risk factor management services.
Geographic Variation in Vascular Dementia in the US 2024
| Geographic Factor | Pattern | Potential Explanation |
|---|---|---|
| Regional Mortality Variation | Significant state-level differences | Coding practices, risk factors |
| Stroke Belt (Southeast) | Higher stroke rates | Higher vascular disease burden |
| Rural vs. Urban | Rural areas show higher burden | Healthcare access, risk factors |
| State-Level Death Rates | Wide variation observed | Multiple contributing factors |
| Regional Vascular Risk Factors | Vary by geography | Diet, lifestyle, healthcare access |
| Midwest Mortality | Plateau observed | Stabilizing trends |
| Southern States | Higher vascular disease rates | Concentrated risk factors |
Data sources: CDC state-level mortality data, Geographic variation studies, National vital statistics by region
Geographic variation in vascular dementia across the United States reflects complex interactions between regional differences in vascular risk factors, healthcare access and quality, diagnostic practices, and death certification patterns. State-level analysis of dementia mortality shows substantial variation in age-adjusted death rates, with some states reporting rates significantly higher than the national average while others show lower rates. These differences partly reflect the well-documented geographic patterns in cerebrovascular disease, particularly the “Stroke Belt” in the southeastern United States where stroke incidence and mortality are substantially elevated compared to other regions.
Rural areas consistently show higher burden of vascular dementia and stroke-related mortality compared to urban centers, attributed to higher prevalence of vascular risk factors (smoking, obesity, hypertension, diabetes), delayed recognition of stroke symptoms, longer transport times to comprehensive stroke centers, and reduced access to specialists capable of diagnosing and managing dementia. Southern states show particularly high rates of vascular disease and associated cognitive impairment, correlating with regional patterns of diet (higher consumption of fried foods, lower fruit and vegetable intake), obesity, diabetes, and historically lower healthcare access for vulnerable populations.
