Omega-3 Fatty Acids Maintain The Brain, Protect Against Degeneration


Regular intake of omega-3 fatty acids may protect the aging brain and provide peripheral biomarkers to predict the risk of cognitive degeneration or decline, according to a recent review.


An optimum supply of omega-3 fatty acids is essential for maintaining the health and proper functioning of the brain. Research has shown that, in people with high levels of these nutrients, supplementing with a combination of B vitamins can prevent brain shrinkage, a hallmark of Alzheimer’s disease.

Other studies have made similar findings. People with high levels of the omega-3 fatty acid docosahexaenoic acid (DHA) are known to be at a 49 percent lower risk of developing Alzheimer’s. DHA has also been demonstrated to have beneficial effects on cognition in age-related cognitive decline.

A role is additionally emerging for omega-3 fatty acids as a therapeutic option in neuropsychiatric disorders, Double-blind placebo-controlled pilot studies have shown that the omega-3 fatty acid eicosapentaenoic acid (EPA) is helpful in the treatment of schizophrenia. Significantly, therefore, patients suffering from schizophrenia and depression have been found to have low levels of omega-3 fatty acids.
