Should medical AI tools be required to meet strict accuracy standards for all ethnic groups?
A study published on June 26, 2026, details a new AI formula called RegAlign designed to improve Alzheimer's detection accuracy for minority groups. By weighting patient data differently, the model narrows the detection gap between minority and white patients to less than 1 percent.
Why it matters
Previous artificial intelligence tools often exhibited lower accuracy for minority populations due to data imbalances in training. This model aims to standardize diagnostic results and provide equitable care to all populations across the United States.
The study utilized MRI scans from 9,007 total participants and analyzed the volume of 144 distinct brain regions. Researchers used a balanced test set of 852 scans to isolate performance metrics from sample size variables.
The players
UT San Antonio Health Science Center
This institution is a leading academic medical center focused on health research and the training of medical professionals.
The details
The RegAlign formula functions by assigning more weight to minority patient data during AI training and utilizes specific brain region information tailored to a patient's ethnicity. This systematic approach helped reduce the share of missed dementia cases to 14.72% for African American patients and 11.13% for Hispanic patients.

Health Landscape
This study advances the capabilities of the UT San Antonio Health Science Center Alzheimer's Research Center by integrating advanced AI formulas into existing diagnostic protocols. It highlights a critical shift in medical research toward correcting historical algorithmic biases in clinical datasets.
The improvement in detection accuracy could lead to more timely Alzheimer's diagnoses and better-tailored treatment plans for minority patients. These advancements aim to ensure that diagnostic standards are equally effective across diverse demographic groups.
The takeaway
This development marks a significant move toward mitigating health disparities in neurological diagnostics. Patients from historically underserved communities may soon benefit from more reliable screening tools as these models are further adapted.
