The Claim
Daily consumption of extra-virgin olive oil at a dose of 30 mL per day for a duration of 6 months improves specific memory scores, including the Wechsler Memory Scale logical memory overall score and delayed memory, in adults with mild cognitive impairment, although these improvements are not significantly different from those achieved with refined olive oil.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with mild memory problems who eat about two tablespoons of extra-virgin olive oil every day for six months get better scores on memory tests, like remembering stories right away and later. But people who eat regular olive oil also get the same benefit, so the extra-virgin kind isn't uniquely better for memory.

Olive oil contains natural substances called polyphenols that act like bodyguards for the brain. They protect the barrier that keeps bad stuff out of the brain, and they help clean up harmful clumps (amyloid) and tangles (tau) that damage brain cells. When the brain is healthier, the parts that handle memory work better, so memory test scores improve.

1 studyPeople who drank extra-virgin olive oil every day did better on some memory tests, but it wasn't a big difference compared to regular olive oil.
