Eye test may predict brain decline in heart patients
NCT ID NCT07607756
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This pilot study looks at whether a simple, non-invasive eye scan (OCT-A) can detect early signs of memory decline in people with atrial fibrillation, a common heart rhythm disorder. Researchers will compare retinal blood vessel patterns in 40 patients with and without mild cognitive impairment. The goal is to see if the retina, often called a 'window to the brain,' could become a practical screening tool for cognitive decline in this high-risk group.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could point toward a simple, non-invasive eye scan to help identify early memory problems in people with atrial fibrillation.
What could go wrong
This is a small, early pilot study with only 40 participants, so results may not apply to everyone. It is designed to test feasibility, not to prove a screening tool works yet.
