Cognitive performance in older adults is inversely associated with fish consumption but not erythrocyte membrane n-3 fatty acids.

Cross-Sectional Study
Human
2014 Mar

This study found that people who ate more fish as kids tended to react more slowly and process information more slowly when they got older, even though we don’t yet know why. So yes, the study backs up the idea that eating more fish as a child might have a surprising downside for brain speed later in life.

Older women with more EPA in their red blood cells tend to think a bit slower, but this isn't because EPA itself affects the brain—it's probably just because they recently ate more fish. Once you account for how much fish they've eaten lately, the link disappears.
