Strong Support

Taking omega-3 supplements doesn't seem to make any difference in the brain changes that happen with mild memory problems in older people.

463. EFFECTS OF 24-MONTH SUPPLEMENTATION OF EPA AND DHA ON HIPPOCAMPAL SPONTANEOUS NEUROACTIVITY IN MILD COGNITIVE IMPAIRMENT AND DEMENTIA: A RESTING-STATE FMRI STUDY

Randomized Controlled Trial

Human

This study gave older adults with memory problems omega-3 pills for two years and found no change in brain activity patterns linked to memory. Since no changes were seen, it suggests omega-3s probably don’t affect the brain damage that causes memory loss.

The association between omega-3 supplementation and cognitive decline in older adults

Cohort Study

Human

This study found that taking omega-3 supplements didn’t change the levels of Alzheimer’s-related brain proteins (amyloid and tau) or brain tissue volume in older adults with memory problems — which is exactly what the claim says. But it did find omega-3 might make memory worse in another way, through brain energy use.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Taking omega-3 supplements doesn't seem to change the brain changes usually seen in Alzheimer's disease, like plaque buildup or brain shrinkage, in older people over five years.

For older people with early memory problems, taking omega-3 supplements might make their memory and thinking skills get worse faster over five years, which is the opposite of what most people think.

Taking omega-3 supplements might be linked to older people's memory and thinking skills getting worse faster, according to some tests doctors use to check brain function.

Taking omega-3 supplements might be linked to a faster drop in brain energy use in areas affected by Alzheimer’s, and this could explain up to 40% of why some older adults’ memories and thinking skills get worse over time.

Taking omega-3 supplements might help people with Alzheimer’s do better on some memory and thinking tests, but not all of them—so the benefits aren’t the same for every type of brain function.
