Dementia is a growing global health crisis with a staggering cost

Alzheimer’s disease and related dementia conditions do not simply rob individuals of memory; they also exact an extraordinary cost on families and on the nation as a whole.

A newly released estimate from researchers at the University of Southern California (USC) concludes that the total monetary burden of dementia in the United States will reach roughly $781 billion in 2024.

That figure surpasses the annual revenues of many Fortune 500 companies and amounts to more than three percent of the nation’s gross domestic product.

Who pays, and how much?

Although various organizations have attempted to calculate dementia costs in past years, the USC‐led project aims to be the most comprehensive to date.

The effort, supported by a multi‐year cooperative agreement with the National Institute on Aging, combines detailed medical claims with large, nationally representative surveys and then applies a sophisticated simulation technique known as dynamic microsimulation.

The result is not only a single headline statistic but also a granular picture of who shoulders which costs, how those burdens change as patients age, and how new treatments or policies might shift the outlook over time.

Julie Zissimopoulos co-directs the Aging and Cognition program at the USC Schaeffer Center for Health Policy & Economics and serves as principal investigator of the U.S. Cost of Dementia project. She noted that the goal is to give decision makers the kind of data they need to design smarter interventions.

“Having a better understanding of who bears these costs and how they change over time can inform evidence-based policies that may ultimately reduce the financial impact of dementia,” explained Zissimopoulos.

Building the dementia model

The research rests on several interlocking data sets. One is the Health and Retirement Study, a biennial survey of more than 20,000 Americans over age fifty that collects information on income, wealth, health status, and family structure.

Another is de-identified administrative data from the Centers for Medicare & Medicaid Services, which capture hospitalizations, physician visits, prescription drug use, and long-term‐care claims.

By merging these resources and running them through dynamic microsimulation, the team can project how a representative cohort of older Americans will move through different health states, how their care needs will evolve, and how each phase translates into dollars.

The headline number of $781 billion covers several major domains of expense. Direct medical and long-term‐care cost for dementia patients – hospital stays, outpatient visits, skilled nursing facilities, home health aides, and other services – adds up to approximately $232 billion in 2024.

Out-of-pocket payments by patients and their families account for 22% of that sum, or about $52 billion.

Medicare remains the single largest payer at $106 billion, while Medicaid, which picks up many nursing-home charges for low-income or exhausted‐asset households, spends about $58 billion.

Dementia cost beyond medical bills

Yet medical bills, staggering as they are, represent only the visible part of the iceberg. The USC model attaches a monetary value to quality-of-life losses for both patients and caregivers.

Economists do this by using survey data on health-related quality of life and applying standard “willingness‐to‐pay” techniques to convert utility losses into dollar terms.

By that yardstick, patients with dementia together lose an estimated $302 billion worth of well-being this year, while family caregivers forfeit an additional $6 billion.

Caregivers also surrender work hours. The model finds that friends and relatives will provide roughly 6.8 billion hours of unpaid care in 2024 – time that could otherwise be spent in the labor force or on personal pursuits. Using average wages to monetize that devotion yields an additional $233 billion.

Enormous economic toll

On top of those unpaid hours are lost wages from people who reduce their schedules or quit altogether to look after loved ones; those forfeited earnings amount to $8.2 billion.

Dana Goldman, founding director of the USC Schaeffer Institute for Public Policy & Government Service and co-principal investigator on the study, emphasized the stakes.

“This research demonstrates the enormous toll dementia places on patients, their families, and care partners,” she said. “But it also points to the potential value of developing ways to prevent and treat Alzheimer’s and related diseases that cause dementia.”

Goldman noted that even modest delays in disease progression could yield huge economic dividends, not to mention immeasurable relief for families.

Dynamic dementia dashboard

The study arrives at a moment of rapid change in dementia care. The Food and Drug Administration has recently approved anti-amyloid drugs that, for the first time, appear to slow cognitive decline in certain patients with early-stage Alzheimer’s.

Blood-based biomarkers promise cheaper and earlier detection, potentially moving diagnosis up by years.

Policymakers, insurers, and pharmaceutical companies are grappling with how to pay for these innovations and how to ensure equitable access. By updating the cost model annually, the experts hope to provide a real-time dashboard that will let stakeholders see how emerging therapies or policy reforms shift both costs and benefits.

Planning for dementia costs

Future reports will incorporate additional cost categories – legal fees, home modifications, transportation expenses, and mental-health impacts – aiming for the most exhaustive ledger yet of dementia’s drain on society.

For now, the $781 billion estimate stands as a stark reminder that the disease is not just a clinical challenge but an economic tsunami, already cresting and bound to grow as the aging population swells.

Evidence-based planning, the researchers argue, is the only way to blunt the tide.
