No evidence of benefits to cognition with omega-3 fatty acids
A new study of the effects of omega-3 fatty acids finds no evidence of improved cognition in those consuming the oil. A total of 2,157 women with normal cognition enrolled in a clinical trial of postmenopausal hormone therapy were followed with annual cognitive testing for a median of 5.9 years.
After adjustment for demographic and other characteristics, no significant cross-sectional cognitive differences were found between women in the high and low DHA + EPA tertiles at the time of the first annual cognitive tests. In addition, no significant differences were found between the high and low DHA + EPA tertiles in the rate of cognitive change over time. The results have been published in Neurology: "Omega-3 fatty acids and domain-specific cognitive aging" Eric M. Ammann et al. Neurology September 25, 2013, doi: 10.1212/WNL.0b013e3182a9584c
