Eating seafood and cognitive decline in older adults

In the article APOE epsilon 4 and the associations of seafood and long-chain omega-3 fatty acids with cognitive decline, van de Rest and colleagues examined the connection between the amount of seafood eaten per week and cognitive decline over approximately 5 years in older adults living in retirement communities. The researchers were also interested in learning more about how a gene called APOE epsilon 4 might influence the effect that seafood consumption has on cognitive decline.(1) The community-based study was designed to better understand changes in thinking and motor abilities and the risk of Alzheimer disease (AD) in older adults. The study was called the Rush Memory and Aging Project or MAP.(2</SUP)
