Fatty acid intake may not prevent cognitive decline

More than 2100 participants in the Women’s Health Initiative study – healthy, dementia-free women aged 65 to 80 – were given annual tests of verbal and spatial ability as well as memory skills over a six-year period.

There was no difference in the rate of cognitive decline among the women who had registered high levels of red blood cell (RBC) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) at baseline compared to those with low levels at baseline.
