Abbreviations: DHA = docosahexaenoic acid; EPA= eicosapentaenoic acid; n-3 = omega-3 fatty acids; n-6 = omega-6 fatty acids. Model 1: age, gender, APOE ε4, education. Model 2: Model 1 plus BMI, physical activity, smoking, cognitive decline, alpha-tocopherol, triglyceridesα, total cholesterol, and lipid-lowering medication (i.e., statins and fibrates). A p-value < 0.05 is considered to be statistical significant.
