Abstract
Abstract Omega-3 fatty acids are integral to the development of the brain. The mechanisms of action and results from research with animal models suggest a role for the omega-3 s, specifically docosahexaenoic acid (DHA), in the development of cognitive abilities. This review explores the actions of DHA in the brain and the animal models that have been developed to explore DHA's effect on learning. This is followed by a review of the human studies of DHA supplementation. DHA's effect on cognition is not wholly evident in the current literature, even though the hypothesis is well-founded. It is proposed that the effects may be more evident with higher levels of supplementation, with more specific cognitive outcomes, or with early supplementation, but later testing.
