Either depression coupled with low DHA or reduced plasma EPA both predict dementia

Sep 19, 2008

French researchers report that two separate markers independently predict a possibility of developing dementia and having either one is risky. Researchers at INSERM in Bordeaux, France evaluated data from 1,214 participants in the Three-City Study. The subjects aged 65 or older did not have dementia upon enrollment and were observed for 4 years. If a person was depressed and they had a higher ration of arachidonic acid in their blood (omega-6 fatty acid) than DHA (the brains favorite fish oil fatty acid) there was a there was a 265% higher risk of developing dementia.

Having a higher level of the Fish Oil fatty acid known as EPA was connected with a 31% drop in the rate of dementia. The study is published in the September 2008 issue of the American Journal of Clinical Nutrition.
