Omega-3 fatty acids help prevent dementia, U.S. study suggests: NewsTarget.com

A study by researchers at Tufts University in Boston has added to growing evidence that suggests increased levels of the omega-3 fatty acid docosahexaenioc acid (DHA) in the blood can significantly lower the risk of dementia and Alzheimer's disease.

"Subjects with baseline plasma PC DHA levels in the upper quartile experienced a significant 47 percent lower risk of dementia, compared with participants with levels in the lower three quartiles," wrote lead author Ernst Schaefer.

The study, published in the Archives of Neurology, comes only a month after scientists from Karolinska University Hospital Huddinge in Sweden reported -- in the same medical journal -- that omega-3 acids might slow the mental decline of people with mild Alzheimer's, although no effect was observed in people with advanced cases.
