Electronic health records — the diagnoses, prescriptions, lab results and visit notes already in your clinic chart — helped researchers flag undiagnosed memory problems in 2026. For people with mild cognitive impairment, which means noticeable memory or thinking changes that do not block daily independence, that means earlier chance for testing and planning. The work does not diagnose dementia by itself. It points primary-care teams toward patients who need a closer look.

What did the 2026 EHR model show?
Researchers built a Gradient Boosting model from routine outpatient records in adults age 60 and older. It distinguished carefully confirmed mild cognitive impairment with test AUC 0.850, accuracy 0.833 and F1 0.402, according to the Frontiers in Neurology study published Feb. 17, 2026.
The model used structured predictors already in the chart. These included demographics, comorbidities, medications, lifestyle factors and visit patterns, with age and education among known risk signals. In practice, the pattern matters more than any single code. Missed visits, new prescriptions and chronic conditions together raised the flag.
How could screening change a primary-care visit?
A tool called eRADAR scans routine EHR elements such as diagnoses, medications, labs, vital signs and chronic conditions to flag patients who may have undiagnosed dementia, as described in the Brain Health Study record. The flag prompts further evaluation, not a diagnosis. Researchers reported at AAIC 2026 in London on July 12-15 that eRADAR-based screening helped primary-care providers identify patients at high risk for mild cognitive impairment and dementia, with targeted outreach tested in pragmatic trials, according to Healio reporting on AAIC 2026.
Clinics then contacted high-score patients for cognitive checks. For families, that contact may look like a phone call, portal message or brief memory questionnaire. A positive screen usually leads to a longer visit, medication review and hearing, mood and sleep checks.
What are the limits for people with MCI?
EHR data reflect routine care, not research testing. Missed diagnoses, coding differences and single-system records can skew results. Internal or single-system validation also limits reach.
A model trained in one network may perform differently in another clinic with different patients or coding habits. Prospective confirmation is still needed before these scores guide care. Treat a high score as a reason to evaluate, not proof of decline.
What practical steps can you take now?
Bring a complete list to each visit, including over-the-counter drugs, sleep aids and alcohol use. Ask whether your clinic uses EHR-based memory screening and what follow-up it offers. Digital alerts alone do not always change prescribing.
In a UCLA pragmatic trial, a behavioral EHR alert for new antipsychotic prescribing in outpatients with dementia did not significantly reduce antipsychotic pill-days over 19 months, according to the UCLA CTSI summary. Human follow-through still decides care quality. If a new brain-active drug is suggested, ask about benefits, side effects and review date.
