In 2026, UAS-CLEAR, a national longitudinal caregiving study, prioritized daily caregiver experience over studying only people with mild cognitive impairment, or MCI. It studied family and non-family dementia and non-dementia caregivers across adulthood, while MCI-specific samples and small groups stayed outside the core data. MCI means early, measurable changes in memory or thinking that do not prevent daily independence. UAS-CLEAR tracks how caregiving affects daily mood and health, so families can see where MCI needs fit and where gaps remain.

Who did UAS-CLEAR study?
The Understanding America Study is a probability-based internet panel of about 10,000 U.S. adults run by USC researchers, according to USC's panel description. It supplies the national sampling frame for UAS-CLEAR lifecourse follow-up. That design reaches caregivers from young adulthood to old age.
UAS-CLEAR develops new survey tools to find caregivers and uses daily surveys plus wearables to link daily life to emotional and bodily well-being, according to the University of Michigan grant summary. It includes family and non-family caregivers for Alzheimer's disease and related dementias and for other conditions. One wave covered 1,300 U.S. caregivers surveyed in August through October 2025, according to the PLOS ONE 2026 report.
Why does caregiver experience lead the data plan?
A diagnosis tells only part of the MCI story. Daily hours, sleep breaks, mood shifts, and physical strain shape outcomes for both caregiver and care recipient.
Real-time surveys capture what happened today, not what a person recalls months later. Wearables add sleep, activity, and stress signals to that self-report. Together they show which routines protect well-being and which routines erode it.
Who stayed outside MCI-focused data?
Small care populations often miss inclusion in MCI studies. The 2026 NIA summit report flags gaps for adolescent caregivers and people with non-Alzheimer's dementias such as frontotemporal dementia and Lewy body dementia, according to the NIA summit report. Those groups need different supports than typical MCI cohorts.
Unequal care access also skews who appears in data. From over 1 million U.S. adults with MCI or dementia, only 2,427 received anti-amyloid drugs, with much lower adjusted odds for Black and Hispanic adults, according to Michigan Medicine. A separate study of 5,757 Medicare recipients found Black and Hispanic patients more likely to have dementia but less likely to show Alzheimer's pathology on scans, according to Vanderbilt researchers.
- Included: adult family caregivers across conditions and ages
- Included: non-family caregivers, a group often missed by family-only surveys
- Undercounted: adolescent caregivers and rare-dementia populations
- Underrepresented: Black and Hispanic adults in treatment and biomarker data
What can families facing MCI do now?
Ask the clinic what type of cognitive change is suspected, not only whether MCI is present. Different causes lead to different follow-up, support needs, and study options. Bring a short log of sleep, confusion episodes, medications, and daily tasks.
Use the caregiver lens for planning. Track who helps, how many hours care takes, and how mood and sleep change after hard days. Share that record with the care team and ask about respite, training, and local support programs.
