Findings from a study by the Fatty Acid Research Institute suggest that people with high levels of omega-3 docosahexaenoic acid (DHA) have half the risk—49 percent—of developing Alzheimer’s disease (AD).
The study found that high levels of DHA are correlated with an extra 4.7 years of being Alzheimer’s-free and an extra 4 years free of all-cause dementia, translating to an additional 2.7 years of life.
The researchers also encouraged individuals that carry the ApoE4 gene—a gene mutation that gives a person the highest risk for late-onset AD—to have an extra intake of dietary DHA, speculating that high consumption of DHA may slow the development of AD….
