Omega 3 fatty acids enhance cognitive flexibility in at risk older adults

Older adults at risk of late-onset Alzheimer's disease who consume more omega-3 fatty acids perform better than their peers on tests of cognitive flexibility - the ability to efficiently switch between tasks, new research finds. The analysis, published in the journal Frontiers in Aging Neuroscience, suggests  that consuming eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) two omega-3 fatty acids found in fish, enhanced cognitive flexibility in these adults in part by beefing up the anterior cingulate cortex.
