Eating more fish might improve your memory, visual conception, spatial motor skills, attention, orientation, and verbal fluency tests. Researchers in Norway have found that elderly men and women who eat fish frequently scored better on several types of cognitive tests than did their counterparts who did not eat fish frequently.
Those scoring higher on the brain tests ate 10 or more grams of fish per day. The fish could be canned, frozen or fresh and also included other fish products like cod liver oil or fish oil. Processed fish sandwiches even seemed to help some score better on some of the tests and lean fish seemed to be just as good as fatty fish.
