In its annual bibliography of significant advances in dietary supplement research for 2006, the National Institutes of Health focused on two studies in the category of “cognitive health.” One, involving gingko biloba, found that a component of this botanical may have therapeutic potential for the prevention and treatment of Alzheimer’s disease. This research on gingko provides further background information for of two large randomized controlled investigations that are now underway: the Gingko Evaluation of Memory study, and the GuidAge study.
A second study in the “cognitive health” category was a clinical trial that followed patients with mild to moderate Alzheimer’s disease who took omega-3 fatty acid supplements, as compared to those taking placebo. A significant reduction in cognitive decline was found in those with very moderate dysfunction who took the omega-3.
This investigation also was undertaken in support of a wider investigation on Alzheimer’s and omega-3s, which is being funded by the National Institutes of Health.
