Medicare-linked dementia surveys are prioritizing caregiver well-being and confidant relationships in 2026, with new findings showing who bears the heaviest burden and who gets left out of support networks. The data comes from the National Health and Aging Trends Study (NHATS), a longitudinal survey funded by the National Institute on Aging that follows a nationally representative sample of Medicare beneficiaries aged 65 and older, enrolled since 2011 with periodic replenishment of new participants, as described in the NIA/NHATS funding notice. For spouses and partners caring for someone with dementia, these surveys matter because they are among the only sources tracking how caregiving affects sleep, stress, and relationship quality over time, using data tied directly to Medicare's beneficiary population.

What Is the Medicare Link, and Why Does It Matter?
NHATS recruits its sample from Medicare's beneficiary rolls, which means every participant's survey answers can be connected to their Medicare claims history. That link lets researchers see not just what caregivers and recipients report, but how those reports line up with actual health care use.
The companion survey is the National Study of Caregiving (NSOC), which interviews unpaid caregivers of NHATS participants. Since 2021, NSOC has run annually rather than periodically, which means researchers now get caregiver-side and recipient-side data every year instead of waiting for occasional survey waves, according to the University of Michigan's MiCDA program. That annual cadence is new enough that 2026 is one of the first years researchers can compare year-over-year trends rather than multi-year gaps.
What the 2026 Sleep Findings Show About Caregiver Strain
A 2026 study in the Journal of Applied Gerontology used NSOC data from 2017 to examine sleep among 784 dementia caregivers. It found that 45% reported excellent or very good sleep, while 80% said the person they cared for rarely or never interrupted their sleep at night, per the Journal of Applied Gerontology study. That combination is worth sitting with: most caregivers are not being woken up by the person they care for, yet more than half still don't report good sleep.
For a spouse or partner, this points to stress, anxiety, or the mental load of caregiving as more likely drivers of poor sleep than nighttime disruptions themselves. A related finding from the NSOC/NHATS network adds another layer. Caregivers who were spouses or adult children, and those who reported higher-quality relationships with the person they cared for, were significantly more likely to be named as that person's confidant, according to MiCDA's Changing Demography of Family Caregiving Network. Being the named confidant carries emotional weight on top of the physical tasks of caregiving, which may help explain why sleep quality lags even without nighttime interruptions.
How the Caregiver Population Has Grown
The number of family caregivers helping older adults rose sharply over the past decade. A 2025 analysis of 2011-2022 data found the total grew from 18.2 million to 24.1 million, an increase of nearly 6 million people, as reported by Johns Hopkins Bloomberg School of Public Health.
Within that larger group, dementia caregivers carry a distinct burden. Earlier NSOC-based research from 2024 found that dementia caregivers reported lower psychological well-being and higher caregiving burden than caregivers supporting people without dementia, though the two groups did not differ on personal impact, per the 2024 NSOC analysis. The Alzheimer's Foundation of America cites a CDC estimate that more than 11 million Americans currently serve as caregivers to someone living with dementia, the population these survey priorities are designed to inform, according to AFA's 2026 announcement.
A New Survey Focused Specifically on Spouses
Separate from the Medicare-linked NHATS/NSOC data, the Alzheimer's Foundation of America launched a free national online survey on August 17, 2026, built specifically to measure how caregiving for a spouse or partner with dementia affects physical health, stress, brain function, social relationships, and quality of life. No findings have been published yet, per AFA's press release.
Eligibility requires being a full-time primary caregiver, age 21 or older, caring for a spouse or partner with Alzheimer's or another form of dementia, living in the U.S. with internet access, and completing a 30-45 minute questionnaire available at alzfdn.org, as outlined in AFA's spousal caregiver study flyer. AFA notes that spousal caregivers' health has historically been understudied compared to other caregiver groups, which is part of the motivation for launching this survey independently of the Medicare-linked data streams.
- Full-time primary caregiver, age 21 or older
- Caring for a spouse or partner with Alzheimer's or another dementia
- U.S. resident with internet access
- Able to complete a 30-45 minute online questionnaire
Why Researchers Can't Act on This Data Instantly
Access to NHATS/NSOC files linked to Medicare administrative records requires a separate Data Use Agreement between researchers and CMS and NIA. That approval process can take roughly a year, which limits how quickly researchers can turn 2026 survey findings into published, actionable results, per the NIA/NHATS funding notice.
For a spouse or partner reading about these survey priorities now, that lag means the most detailed Medicare-linked findings on any given year's data typically surface well after the fact. The AFA's independently run spousal survey, by contrast, is not bound by that same CMS data agreement timeline, since it collects its own responses directly rather than linking to Medicare records.
Frequently Asked Questions
Is the AFA spousal caregiving survey the same as NHATS or NSOC?
No. AFA's survey, launched August 17, 2026, collects its own data independently; NHATS and NSOC are Medicare-linked surveys run through NIA funding.
Can a caregiver for a parent, not a spouse, take the AFA survey?
No. Eligibility is limited to full-time primary caregivers of a spouse or partner with Alzheimer's or another dementia.
Why does the Medicare link in NHATS matter for dementia caregiving data?
It lets researchers connect survey answers about caregiving and sleep directly to participants' actual Medicare claims history, not just self-reports.
