利用创新改善美国农村阿尔茨海默氏症的诊断和护理

SANDRA BARBOSU AND LILA TROLLIP| MARCH 2026 Rural communities face structural barriers to diagnosing Alzheimer’s early, which increasesburdens on patients and caregivers while raising health-care costs. Policymakers should addressthe problem by expanding provider training and accelerating scalable diagnostic technologies. KEY TAKEAWAYS Rural communities face heightened Alzheimer’s risk due to older populationdemographics, compounded by structural, geographic, and financial barriers to care. Delayed diagnosis increases downstream health-care spending, intensifies caregiverburden, and contributes to workforce losses in already fragile rural economies. New technological innovations—including blood-based biomarkers, digital cognitivescreening tools, and FDA-approved therapeutics—offer solutions that can expand access Targeted federal and state policies are essential to improve timely Alzheimer’s diagnosisin rural America, including strengthening the rural health workforce, accelerating access CONTENTS Key Takeaways................................................................................................................... 1Introduction....................................................................................................................... 2Challenges in Rural America................................................................................................ 4Economic Burden of Alzheimer’s in Rural Areas .................................................................... 6 itif.org Conclusion ...................................................................................................................... 16Endnotes......................................................................................................................... 17 INTRODUCTION Alzheimer’s disease represents one of the most pressing and costly public health challengesfacing the United States. As the population ages, the prevalence of Alzheimer’s continues to risesharply, with millions of Americans already affected, and projections indicating substantialgrowth in the coming decades. Despite more than a century of scientific inquiry, Alzheimer’sremains difficult to diagnose early, with patients often waiting years between the onset of The consequences of delayed and inequitable diagnosis are particularly severe in rural America.Rural populations are older on average, are aging more rapidly, and face shrinking caregivingworkforces—factors that increase both the risk and impact of Alzheimer’s disease. Yet, thesecommunities frequently lack access to specialized clinicians and diagnostic infrastructure—suchas positron emission topography (PET) imaging and advanced biomarker testing—thatincreasingly define the standard of Alzheimer’s care. As a result, rural residents are more likely to Status and Prevalence of Alzheimer’s Disease Due to an aging population, America is facing an unprecedented Alzheimer’s crisis. As of themost recent statistics, published in 2024, more than 6 million Americans are living withAlzheimer’s disease, and some projections suggest that this number could more than double tonearly 14 million by 2060.1Alzheimer’s is currently the seventh-leading cause of death in the The number of people with Alzheimer’s disease increased drastically from 1990 to 2019, morethan doubling from 2.88 million to 6 million, largely reflecting population aging and longer lifeexpectancy—a testament to the strengths of the U.S. health-care system. Yet, despite more than Furthermore, disability-adjusted life years (DALYs) due to Alzheimer’s disease have more thandoubled since 2000, increasing from 11.8 million to 32.6 million. DALYs represent the numberof healthy years of life lost due to disability and are among the most widely used indicators ofdisease burden. This dramatic increase underscores the persistent and growing impact of The consequences of delayed diagnosis extend far beyond patients themselves. Alzheimer’simposes a substantial burden on caregivers, health systems, and the broader economy. Theoutward symptoms of Alzheimer’s—such as memory loss, confusion, and emotionaldysregulation—are often referred to as dementia. Global dementia-related costs are projected toreach $2 trillion in 2030. In the United States alone, per-patient costs are substantial: in 2016,formal care costs were $28,078 per patient, while the costs for informal caregiving, when relatives care for patients free of charge, continue to add $36,667 in replacement costs and$15,792 in forgone wages each year. Analysts estimate total formal (paid) care costs to be $196 The challenges are particularly acute in rural communities. Rural populations are older onaverage, experience higher rates of disability, and are aging faster than urban populations—factors that increase Alzheimer’s risk and severity.6Yet, rural areas often lack access totraditional diagnostic infrastructure, such as PET imaging and lumbar punctures, performed
