New study - Omega-3s no help with Alzheimer's
Omega-3 fish oils do not slow the cognitive decline of people with Alzheimer's disease. Researchers from Oregon Health and Science University studied 215 people with mild to moderate Alzheimer's disease. Over 18 months 171 of them took fish-oil tablets while the rest took a placebo. The researchers tested the participants' cognitive abilities and, in a smaller group of participants measured their brain volumes with an MRI scanner. The researchers found that taking the fish oil had no beneficial effects on the participants' cognition and no effect on total brain volume. The authors concluded that "in summary these results indicate that DHA (docosahexanoic acid, an Omega-3 found in fish oil) supplementation is not useful for the population of individuals with mild to moderate Alzheimer disease."
