Omega-3 Supplements Do Little to Slow Cognitive Decline

A randomized trial gave either a placebo or 2 grams a day of docosahexaenoic acid (DHA) to about 400 adults with mild-to-moderate Alzheimer Disease (AD) for 18 months. At the end of treatment there was no difference between the groups, showing that these supplements did not slow the rate of cognitive decline. 

PositiveTip: DHA supplementation probably results in little improvement among patients with AD.
