Hi :

Interesting study, thanks, here is the abstract:

" Fish Consumption and Cognitive Decline With Age in a Large Community

Study

Arch Neurol. 2005;62:(doi:10.1001/archneur.62.12.noc50161).

ABSTRACT

Background Dietary intake of fish and the -3 fatty acids have been

associated with lower risk of Alzheimer disease and stroke.

Objective To examine whether intakes of fish and the -3 fatty acids

protect against age-related cognitive decline.

Design Prospective cohort study.

Setting Geographically defined Chicago, Ill, community.

Participants Residents, 65 years and older, who participated in the

Chicago Health and Aging Project.

Main Outcome Measure Change in a global cognitive score estimated

from mixed models. The global score was computed by summing scores of

4 standardized tests. In-home cognitive assessments were performed 3

times over 6 years of follow-up.

Results Cognitive scores declined on average at a rate of 0.04

standardized units per year (SU/y). Fish intake was associated with a

slower rate of cognitive decline in mixed models adjusted for age,

sex, race, education, cognitive activity, physical activity, alcohol

consumption, and total energy intake. Compared with a decline rate in

score of –0.100 SU/y among persons who consumed fish less than

weekly, the rate was 10% slower (–0.090 SU/y) among persons who

consumed 1 fish meal per week and 13% slower (–0.088 SU/y) among

persons who consumed 2 or more fish meals per week. The fish

association was not accounted for by cardiovascular-related

conditions or fruit and vegetable consumption but was modified after

adjustment for intakes of saturated, polyunsaturated, and trans fats.

There was little evidence that the -3 polyunsaturated fatty acids

were associated with cognitive change.

Conclusions Fish consumption may be associated with slower cognitive

decline with age. Further study is needed to determine whether fat

composition is the relevant dietary constituent.

Hi Suwsan:

And this looks like the full study:
