In this study, higher levels of omega-3s were linked with larger hippocampal volumes and improved cognition, and the increases seen continually with each step measurement of the omega-3s. All measured omega-3 predictors were tied to better abstract reasoning test scores. Participants in the top three quartiles of EPA levels had better abstract reasoning performance than those in the bottom EPA quartile. The associations remained after adjusting for vascular risk factors.
