Omega-3s from fish oil preserve cognitive function

Researchers said one study was the first to report lower chances of cognitive decline in those who took omega-3 supplements.

At the start of the study, doctors measured the diets and cognitive performance of 1,475 adults without dementia, aged at least 55. Doctors tested again 1.5 years later and found those who took omega-3 fish oil supplements were 63 percent less likely to show signs of cognitive decline.

Summarizing their findings, study authors said the omega-3 fatty acids EPA and DHA may lower chances of cardiovascular disease, improve cerebral blood flow, decrease inflammation, and slow the progression of Alzheimer’s disease, all of which may help reduce the rate of cognitive decline.
