The Claim
Twenty-four months of supplementation with EPA (0.8 g/day), DHA (0.35 g/day), or their combination does not significantly alter spontaneous hippocampal neural activity, as measured by amplitude of low-frequency fluctuations (ALFF), in individuals with mild cognitive impairment or dementia.
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.
Taking omega-3 fish oil supplements daily for two years doesn't seem to change the brain's natural low-level activity in people with memory problems or dementia, at least not in the way we measure it.
See the scientific wording
Twenty-four months of supplementation with EPA (0.8 g/day), DHA (0.35 g/day), or their combination does not significantly alter spontaneous hippocampal neural activity, as measured by amplitude of low-frequency fluctuations (ALFF), in individuals with mild cognitive impairment or dementia, suggesting that omega-3 fatty acids may not exert neuroprotective effects through this specific neural mechanism.
What the research says
1 studyThis study gave people omega-3 supplements for two years and checked if their brain's natural activity changed, using a special scan. It found no change, meaning these supplements didn't affect this particular brain signal, which supports the claim that they don't work through this mechanism.
