The 2026 NIA report points to collaborative care models and caregiver programs such as REACH II as closest to wider use. People with mild cognitive impairment, early thinking and memory changes that leave daily tasks intact, can ask about eligibility, duties, risks, and outcomes. The National Institute on Aging hosted the summit virtually March 17-19, 2026.
Its report covers costs, partnerships, interventions, care models, data infrastructure and lived experience, described in the 2026 summit report. NIA estimates total annual U.S. dementia costs at $781–$800 billion when medical, long-term-care and unpaid caregiving count, with heavy impact on families and Medicaid.

Which interventions look closest to use?
An AHRQ review for the National Academies examined collaborative dementia-care models. It found low-strength evidence that these models improve quality of life for people living with dementia, summarized in the National Academies evidence chapter.
The same AHRQ review examined REACH II, a multicomponent caregiver program, and its adaptations. It found low-strength evidence that the program reduces caregiver depression at about 6 months.
What does coordinated care include day to day?
The Centers for Medicare & Medicaid Services says GUIDE pays for comprehensive dementia care. It uses an interdisciplinary team, a care navigator, and 24/7 support-line access.
It also offers caregiver education, community referrals, and respite for qualifying caregivers, detailed on the GUIDE Model page. CMS describes GUIDE as an 8-year voluntary national model that started July 1, 2024. It tests whether coordinated dementia care delays nursing-home placement and helps caregivers support people at home.
Where is the evidence still thin?
National Academies reporting cautions that most intervention studies are small and short-term. They focus on individual action rather than community or policy change.
The same reporting notes the studies do not reflect diverse races, ethnicities, ages, genders, sexual orientations, or abilities. That gap matters when you ask whether results apply to your family and neighborhood.
What should you ask before joining a study?
NIA advises people with mild cognitive impairment to contact study staff with questions before enrolling. Staff can be found through the Alzheimers.gov trial finder or the ADEAR Center. Ask these focused questions at first contact: Bring written answers to your clinician and care partner, then decide together whether the schedule and duties fit your life.
- MCI eligibility and how you confirm it
- functional requirements for daily activities
- caregiver duties and time involved
- risks and outcomes measured
- how past participants reflect age, background, and ability
