Summary

This study tests a simple, low-cost method to find undiagnosed dementia in older adults during routine primary care. Researchers use an algorithm (eRADAR) that scans electronic health records to identify people who may have dementia but haven't been diagnosed. Those flagged are offered a brief in-person brain health assessment. The goal is to see if this approach increases new dementia diagnoses and helps catch the condition earlier.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
eRADAR algorithm (electronic health record screening tool) and Brain Health Assessment (cognitive screening by health practitioners)
What this could lead to
If successful, this approach could enable widespread, low-cost dementia screening in primary care, catching cases earlier and improving patient outcomes.
What could go wrong
The algorithm may miss some cases or lead to false positives, and the study is testing detection, not treatment—so earlier diagnosis alone may not improve health without effective therapies.
