Researchers using electronic health records still undercount people with mild cognitive impairment in 2026. Electronic health records are digital clinic charts, and mild cognitive impairment means early memory or thinking changes that do not yet block daily life. They still need to learn how missing codes, unequal treatment records, and absent caregiver details distort research. Studies now pair record screens with brief tests and chart review to fill those gaps.

Why do records miss early impairment?
About half of people living with dementia lack a formal diagnosis, so researchers built record-based screens to flag high-risk patients for targeted checks, according to Healio's AAIC 2026 report. The gap is largest at the mild stage. Early symptoms often go unrecorded or use vague notes.
Diagnosis codes alone do not find these cases. A retrospective study of older adults in 59 primary-care clinics found codes had to be combined with medications and other signals. Researchers cannot treat a missing code as proof of no impairment.
What does a better screen add?
The eRADAR tool uses only routine record data such as demographics, chronic conditions, vital signs, and visit patterns. It was built with machine learning to predict undiagnosed dementia without extra testing. That approach lets clinics scan large panels quickly.
A brief test can then confirm risk. In an NIH-funded trial of 1,201 mainly Black and Hispanic Bronx patients, the five-minute 5-Cog test plus a record-based decision tree tripled the odds of dementia care actions within 90 days, the National Institutes of Health reported. The lesson for research is direct. Pair the record flag with a short cognitive check.
- Flag high-risk patients with routine record data
- Add a five-minute structured test at the visit
- Trigger clear next steps in the record
Who is missing from treatment data?
Prescribing records show sharp inequities for newer therapies. Analysis of 1,198,362 U.S. patients found only 2,427 received anti-amyloid drugs, with Black patients having far lower adjusted odds than White patients, Medscape reported.
Higher neighborhood vulnerability further lowered use. Researchers studying mild cognitive impairment must read low prescribing as access, not biology. Eligibility, referral, cost, and clinic capacity shape who appears as treated. Studies need subgroup and neighborhood context to avoid false conclusions.
Where do caregivers fit in?
Few caregivers of older adults with dementia have shared or proxy access to the patient portal. That limits how well systems can identify care partners. It also limits outreach for studies and follow-up care.
The National Institute on Aging lists better survey tools, ethical frameworks, and access to records, claims, financial, and driving data as still-needed infrastructure. Attention to disparities across causes and subgroups is part of that agenda. For mild cognitive impairment, caregiver reports can catch functional change that visits miss.
What should readers do now?
Patients and families can ask that memory concerns be coded clearly. Bring a medication list, a symptom timeline, and a care partner when possible.
Ask whether the clinic uses a brief structured test. Researchers should combine codes with medications, vital signs, use patterns, brief tests, and chart review. That layered method reduces bias from records that undercapture early impairment.
