Perhaps most importantly, DHA is critical to the development of the human cortexthe part of the brain responsible for higher-order thinking. The buildup of cholesterol plaques in brain blood vessels can damage brain tissue, either through small blockages that cause silent strokes, or a larger, more catastrophic stroke.
