The 2026 NIA summit report says mild cognitive impairment (MCI), early memory or thinking decline, and dementia are underdiagnosed. It says routine risk-based screening, enhanced screeners, and records-based tools can improve early detection across care settings for spouses and partners. For a partner, a late diagnosis delays treatment choices and family planning. This briefing explains what helped detection, where limits remain, and what to ask next.

Why diagnoses come late
MCI can progress quietly, and busy visits miss early change. The National Institute on Aging reports that professional guidelines do not consistently recommend screening. The U.S. Preventive Services Task Force found insufficient evidence to recommend for or against routine screening over age 65, according to the National Institute on Aging.
That gap leaves many families without a clear prompt to test. The impact is concrete. The National Institute on Aging describes in the 2026 summit report a woman who needed a two-year effort for an MCI diagnosis in her early 60s. The delay slowed access to FDA-approved donanemab, while her husband delayed Medicare enrollment and updates to wills and powers of attorney.
What improved detection in primary care?
One approach paired a brief questionnaire with existing records data. The trial used the 10-question Quick Dementia Rating System plus a Passive Digital Marker AI that reads existing electronic health record data. The test ran in nine Indianapolis federally qualified health centers with 5,325 patients from July 2022 to July 2024.
Clinics using the combined method had 31% higher odds of a new Alzheimer's-related dementia diagnosis than usual-care clinics, according to JAMA Network Open in the trial report. A second program tested TabCAT Brain Health Assessment. Across 21 primary-care providers and 2,733 patients, provider adoption reached 95% and providers were 72% more likely to diagnose a cognitive disorder than before, according to the National Institute on Aging in the 2026 NIH ADRD progress report.
Can a five-minute test narrow gaps?
5-Cog is a five-minute test of memory, gait-linked cognition, and symbol matching. It is designed for use by non-specialists and to reduce cultural bias. NIH-funded researchers tested it in 1,200 older adults with cognitive concerns, mostly Black and Hispanic adults.
That focus matters because language, schooling, and referral patterns can skew older tests. For spouses, the practical point is access. A short test that does not require a specialist can fit a primary-care visit and prompt timely follow-up.
What should spouses do next?
Ask for cognitive screening at the Medicare annual wellness visit. Bring specific examples of change, current drugs, sleep issues, and mood shifts.
After a diagnosis, act while decision-making capacity remains: The National Institute on Aging frames early legal and financial planning as a spouse-level benefit of earlier detection. Complete those papers soon after diagnosis while choices stay clear.
- update wills, powers of attorney, and health-care directives
- review Medicare, work leave, driving, and home safety plans
- ask the clinician about referrals, support services, and follow-up testing
