Olive oil compounds may shield the aging brain from memory decline
NCT ID NCT07741773
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This trial tests whether a daily supplement of extra-virgin olive oil (EVOO) phenolics can improve memory and brain function in people with mild cognitive impairment (MCI), a condition that sometimes progresses to Alzheimer's disease. Over six months, participants will take either the EVOO supplement or a placebo, and researchers will measure changes in cognitive test scores, brain blood flow, and blood biomarkers linked to Alzheimer's. The goal is to see if this natural compound can slow or prevent the decline toward dementia.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- extra-virgin olive oil (EVOO) phenolic dietary supplement
- What this could lead to
- If successful, this could point toward a simple dietary supplement that helps preserve memory and may delay progression from mild cognitive impairment to Alzheimer's disease.
- What could go wrong
- This is a small, early-stage trial with only 20 participants, so results may not apply broadly. The supplement may not improve cognition or biomarkers, and the 6-month duration may be too short to see meaningful changes.
