Selenium Loss Linked to Cognitive Decline
in Aged
(NY, Reuters Health, 2/1/07)
Dr. N. Tasnime Akbaraly, of Universite Montpellier, and
team, recruited 1,389 French seniors in1991 and 1993, 703 of
whom completed the 9-year study, which had 6 follow-ups. The
researchers recorded the subjects’ social and demographic
information and administered tests that measured cognitive
function (i.e. information processing capabilities). The
investigators found that participants whose selenium levels
dropped the most over time had the greatest risk of
cognitive decline. The scientists speculate that selenium,
an antioxidant, may protect cognitive function in seniors by
fighting oxidative stress.
