Ginkgo Evaluation of Memory (GEM)

Long Name: Ginkgo Evaluation of Memory (GEM)

The GEM study is an investigational research study sponsored by the National Center for Complementary and Alternative Medicine, the National Institute on Aging, and the National Heart, Lung, and Blood Institute (each a part of the National Institutes of Health).

The goal of this study is to find out if medicine made from the plant Ginkgo biloba can prevent or delay the changes in memory, thinking, and personality that can occur as people get older. Doctors refer to these changes as "dementia," the most well known type being Alzheimer's disease.

We have enrolled over 3000 people in this study. Half are taking pills that contain Ginkgo biloba, and half are taking a "placebo" (pills that do not contain Ginkgo biloba). After five years, when the study has been completed, we will compare the two groups to see if there are differences in how memory, thinking, and personality have changed, and to see if Ginkgo biloba has been effective in preventing these changes.
