Folic acid, vitamin B-12 boost cognitive brain function: NewsTarget.com

It has long been known that folate and vitamin B-12 are important to the healthy functioning of the nervous system. Now a new study published in the American Journal of Clinical Nutrition suggests that the interaction between these nutrients may play a significant role in protecting cognitive function as a person ages.

The study, conducted by the USDA Human Nutrition Research Center on Aging at Tufts University, found that among seniors with adequate vitamin B-12 levels, high levels of blood folate were associated with better cognitive function. Among seniors with low B-12 levels, however, scores on tests of cognitive function actually decreased with increasing folate levels.

The researchers studied data on people over the age of 60 from the National Health and Nutrition Examination Survey, conducted between 1999 in 2002. Cognitive function was measured by tests of response speed, attention span, visual spatial skills, associative learning and memory.
