The ageing profile of our population holds challenges for society, with some of the major impact due to loss of independence and quality of life in older people, arising from decline in cognitive functioning. Evidence suggests a benefit of Omega-3 fatty acids on cognitive functioning in older people but claims that Omega-3 slows cognitive decline have not been adequately tested. This study tests the effect of Omega-3 supplementation on cognition in healthy older people, over an 18-month period.
