" Effects of omega-3 fatty acids.

Cognitive function in normal aging. In a single prospective

cohort study 59 that evaluated the effects of omega-3 fatty

acid on cognitive function in normal aging, there was no

significant association between omega-3 FA intake in the

form of fish consumption and cognitive decline.

Incidence of dementia. Among three prospective cohort

studies 21, 23, 67 that assessed the effects of omega-3 FA

on the incidence of dementia, fish consumption was

associated with a statistically and clinically significant

reduction in the incidence of non-Alzheimer's dementia in

all three. 67 Fish consumption was associated with a reduced

risk of Alzheimer's dementia in all three of the studies;

the association was statistically significant in one 67 and

nearly so in the other two 21, 23 (Table 3.2). Total omega-3

FA consumption and consumption of DHA were associated with a

significant reduction in the incidence of Alzheimer's

disease for the general population; consumption of ALA and

EPA were not. 23 Among individuals who were APOE-4 positive,

ALA was associated with a reduced risk. "
