The $781 billion is the estimated yearly U.S. economic impact of dementia described in the 2026 National Institute on Aging summit report. Economic impact here means medical care plus unpaid care plus lost quality of life.
Spouses and partners can check local help through their Area Agency on Aging, dementia information lines, and their regular clinic. The total applies to about 5.6 million people living with dementia. The National Institute on Aging breaks it into $232 billion for medical and long-term care and $233 billion for unpaid care, according to the 2026 Dementia Care and Caregiving Research Summit Report. The rest reflects modeled quality-of-life loss, not a medical bill.

What makes up the $781 billion
The USC-led 2025 model divides the total into three parts. It assigns $232 billion to medical and long-term care, $233 billion to informal care, and $302 billion to patient quality-of-life loss, according to the USC Schaeffer Center in its 2025 cost analysis. Those parts sum to $781 billion for 5.6 million people with dementia.
An updated USC-led study puts 2026 costs higher, at $818 billion for 5.7 million Americans. Unpaid care and quality-of-life effects drive much of that rise. For a spouse, the message is direct: most of the national total is not hospital spending.
Why spouses carry so much of the cost
Spouses, family, and friends provide 6.8 billion hours of unpaid dementia care each year. That time was valued at $233 billion in 2025 and $237 billion in 2026, plus about $8 billion in forgone caregiver earnings. Help with meals, medicines, supervision, rides, and nighttime needs counts in that total.
The Alzheimer's Association reports a larger caregiving footprint for 2025: 12.7 million unpaid caregivers gave 19.6 billion hours, valued at $446.3 billion, with higher emotional distress and health risks. The two sources use different populations and valuation methods. Both point to the same home reality: a partner often provides daily skilled support without pay.
What the number does not prove
The $781 billion and $818 billion figures measure costs associated with living with dementia. They are not strictly dementia-attributable costs. They also include modeled values for unpaid hours and quality-of-life loss.
That helps explain a different number many readers see. The Alzheimer's Association projects $409 billion in 2026 health, long-term, and hospice costs, excluding unpaid care, with $263 billion from Medicare and Medicaid and $103 billion out of pocket, according to the 2026 Facts and Figures. Use $409 billion when comparing medical bills. Use $781 billion when describing the wider household burden.
What spouses and partners can check locally
A short local check can turn the national estimate into practical help. Ask what is available now, who qualifies, and what the wait is. Bring a medication list and a one-page list of daily tasks that feel unsafe or exhausting.
- Call ADEAR at 800-438-4380 for dementia information and referrals.
- Call Eldercare Locator at 800-677-1116 to reach the local Area Agency on Aging.
- Ask the clinic about GUIDE enrollment or a dementia specialty-clinic referral, as described in National Institute on Aging clinician guidance on caring for older patients with cognitive impairment.
- Ask the Area Agency on Aging about respite, caregiver training, adult day services, and home safety review.
