Memory Improvement With Docosahexaenoic Acid Study (MIDAS)
A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Effects of DHA on Cognitive Functions in the Elderly

The purpose of this study is to investigate the effect of docosahexaenoic acid (DHA, 22:6n-3) in improving cognitive functions in subjects with age-related cognitive decline. DHA is a long chain omega-3 fatty acid (LC-PUFA) that plays an important role in neural and visual development and cardiovascular health.
