Early-diagnosis economics means finding dementia sooner to protect independence, health and household money. The 2026 National Institute on Ageing report links that value to faster diagnosis and steady follow-up, which spouses can check with four local questions.
The report is second in a three-year series. It finds delays in diagnosis, gaps in primary care, inconsistent follow-up, poorly coordinated care and inequitable access, according to the National Institute on Ageing. It estimates 772,000 Canadians live with dementia, with global undiagnosed rates suggesting up to 2 million may be affected, according to the same report.

Why does timing change value for families?
Dementia costs are large and fall heavily on households. The NIA-funded U.S. Cost of Dementia project estimates U.S. dementia costs will reach $818 billion in 2026, with lost well-being as the largest share, according to USC Mann School and Schaeffer Institute analysis. Patients, spouses and caregivers all share that loss.
Starting care earlier can extend time at home. USC Schaeffer modeling of donanemab, sold as Kisunla, finds starting treatment two years earlier raises total patient, care-partner and societal value by one-third, according to USC Schaeffer Center research. The gain comes from longer independent living and longer life expectancy. Diagnosis at mild cognitive impairment also matters. That stage means clear memory or thinking changes with daily tasks still manageable. Alzheimer's Association modeling finds diagnosing 88% of future cases at that stage rather than dementia could save about $7 trillion in lifetime medical and long-term-care costs.
What four questions can you ask locally?
The Canadian report sets four fixes spouses can use as a checklist. They are national care standards, better-enabled providers, equitable and culturally safe care, and common provincial progress metrics, according to the National Institute on Ageing.
Bring these questions to a clinic, memory program or community agency. Ask for names, wait times and written next steps.
- Do you use a clear care standard for diagnosis and follow-up?
- How do you help primary-care staff spot signs and refer quickly?
- How do you offer equitable and culturally safe care for our needs?
- How do you measure progress in ways families can see?
Does a blood test change when to seek evaluation?
A blood test can now support specialty evaluation. The Food and Drug Administration cleared Fujirebio's Lumipulse G pTau217/β-Amyloid 1-42 plasma-ratio test on May 16, 2025, for adults 55 and older with cognitive signs in specialty care to detect amyloid plaques, according to the FDA clearance announcement. Amyloid plaques are protein clumps linked to Alzheimer's disease. The test is not a screen on its own.
It is not cleared for people without symptoms, and FDA use requires history, labs and cognitive assessment, according to a JAMA Viewpoint on FDA clearances. Coverage and access remain limited. Ask what an evaluation includes before the blood draw. A complete visit should pair the test with medical history, lab work and thinking tests.
How can partners protect money and get help at home?
Early thinking changes can affect money handling. NIA-supported household research finds early-stage Alzheimer's raises risk of large liquid-asset and net-wealth losses through impaired money management, according to Georgetown University researchers. Partners can ask programs about legal, financial and fraud safeguards.
Daily support can come through a federal care model. Medicare's GUIDE model, running July 1, 2024 through June 30, 2032, pays community practices for a navigator, a 24/7 line, caregiver training and up to $2,500 yearly respite, according to the federal GUIDE model page. A navigator is a named contact who coordinates care. Ask your local program if it takes part in GUIDE and who qualifies for respite funds.
