According to a new study, high long-chain omega-3 polyunsaturated fatty acid content in blood may lower the risk of small brain infarcts and other brain abnormalities in the elderly. The study was published in Journal of the American Heart Association.
Research shows that silent brain infarcts, which are only detected by brain scans, are found in about 20% of otherwise healthy elderly people.
The study found that those who had high long-chain omega-3 polyunsaturated fattyacid content in blood had about 40% lower risk of having small brain infarcts compared to those with low content of these fatty acids in blood. The study also found that people who had high long-chain omega-3 polyunsaturated fatty acid content in blood also had fewer changes in the white matter in their brains.
Previously in this same study population, similar findings were observed when comparing those with high or low intake of fish. High content of long-chain omega-3 polyunsaturated fatty acids in blood is a marker for high intake of fatty fish, so the results from the current study support the beneficial effects of fish consumption on brain health.
