New study finds Ginkgo ineffective in dementia prevention

Contemporary Long-Term Care Weekly, November 20, 2008

A new government-funded study designed to examine the effectiveness of ginkgo biloba extract in preventing dementia found the supplement to be no better than a placebo, CNN reported November 18. In the study, more than 1,500 elderly volunteers (ages 75 or over) took either a twice-daily placebo or ginkgo supplement for six years. Every six months, researchers tested the mental abilities and memory function of participants.

Unfortunately, the study revealed no difference between the herbal supplement and the placebo in terms of ability to prevent dementia, according to CNN. The study, which was sponsored by the National Center for Complementary and Alternative Medicine and the National Institute on Aging, can be found in the November 19 issue of the Journal of the American Medical Association.
