The Ideal Dementia Care Map discussed by NIA in 2026 is a practical diagram of more than 200 best practices, from risk reduction through timely diagnosis to medical, psychosocial and community support. For spouses and partners, it frames two urgent questions: who pays the very high cost of care, and how to get support before crisis caregiving begins. The Ideal Dementia Care Map means one actionable overview for policymakers, payers, clinicians, families and technology developers. The overview was summarized for the summit by CATALAIZE's Wen Dombrowski, according to the National Institute on Aging in its 2026 Summit Report.

What does the map cover?
The map was developed by an international team led by Wen Dombrowski to connect risk reduction, timely diagnosis and ongoing community support in one care pathway. The goal is coordinated planning, not separate referrals that families must link themselves.
The underlying study appeared as Dombrowski and colleagues' "Dementia Ideal Care: Ecosystem Map of Best Practices and Care Pathways" in the Journal of Alzheimer's Disease in June 2024. The authors conclude the map is a practical tool for planning and coordinating care, as reported by Biotech Spain in its international project report.
How large are U.S. dementia costs in 2026?
A USC-led 2026 cost model estimates total U.S. dementia costs at $818 billion in 2026 among about 5.7 million people living with dementia.
Lost quality of life for patients and care partners plus unpaid care drive much of that total, according to the USC Schaeffer Center in its 2026 dementia cost study. Medical and long-term care totaled $222 billion, including $110 billion in Medicare and $44 billion in Medicaid. Those paid-care dollars sit beside much larger family and well-being losses.
Why do spouses and partners carry so much?
About 5.2 million spouses, family members and friends provided 6.8 billion unpaid hours valued at $237 billion. Only about 27 cents of every dementia dollar flows through the health system.
Families therefore shoulder more than three times the cost borne by health systems and government once wages, out-of-pocket costs and quality-of-life losses are counted. A spouse who cuts work hours, pays for supervision and loses sleep absorbs costs that never appear on a medical bill.
How can spouses get navigator and respite support?
CMS's Guiding an Improved Dementia Experience, or GUIDE, Model assigns enrolled Medicare beneficiaries a care navigator and interdisciplinary team. Enrolled families receive comprehensive assessment and care planning, 24/7 clinical access and capped respite at no patient cost-sharing, according to CMS on its GUIDE Model page.
The respite benefit most tangible to spouses is about $2,500 per beneficiary per year for temporary substitute care. A partner can use that time to rest, travel or handle an emergency. Ask early, before exhaustion sets in:.
- Seek early cognitive assessment to allow planning while choices remain open.
- Ask primary care whether a GUIDE-participating practice is available locally.
- Ask who serves as navigator, how the 24/7 line works and how respite is arranged.
- These dollar and map figures are modeled estimates and best-practice catalogs, not guarantees of local availability or GUIDE eligibility.
