"In the analysis, published online Monday in the journal Neurology, scientists examined 1,575 dementia-free men and women whose average age was 67"

"People in the lowest one-quarter for omega-3 levels had significantly lower total cerebral brain volume than those in the highest one-quarter, even after adjusting for age, body mass index, smoking and other factors. They also performed significantly worse on tests of visual memory, executive function and abstract memory than those in the highest one-quarter. There was no significant association with white matter hyperintensity volume.

“We feel that omega-3’s reduce vascular pathology and thus reduce the rate of brain aging,” said Dr. Zaldy S. Tan, the lead author and associate professor of medicine at the University of California, Los Angeles.

Few in the study were taking omega-3 supplements, Dr. Tan said. The main reason that some had higher blood levels of omega-3’s was that they ate more fatty fish.

Several of the authors have financial relationships with pharmaceutical companies."
