SUPPLEMENTS

Folate (vitamin B9) is critical to the health of the nervous system. Together with some other B vitamins, folate is also responsible for clearing homocysteine (a body chemical that contributes to chronic illnesses) from the blood. High levels of homocysteine and low levels of both folate and vitamin B12 have been found in people with AD. Although the benefits of taking these B vitamins for AD is not entirely clear, it may be worth considering them, particularly if your homocysteine levels are high.

Antioxidant supplements, like ginkgo biloba and vitamin E, scavange free radicals. These products of metabolism are highly reactive and can damage cells throughout the body.

Vitamin E dissolves in fat, readily enters the brain, and may slow down cell damage. In at least one well-designed study of people with AD who were followed for 2 years, those who took vitamin E supplements had improved symptoms compared to those who took a placebo pill. Patients who take blood-thinning medications like warfarin (Coumadin) may should talk to their doctor before taking vitamin E.

Ginkgo biloba is an herb widely used in Europe for treating dementia. It improves blood flow in the brain and contains flavonoids (plant substances) that act as antioxidants. Although many of the studies to date have been somewhat flawed, the idea that ginkgo may improve thinking, learning, and memory in those with AD has been promising. DO NOT use ginkgo if you take blood-thinning medications like warfarin (Coumadin) or a class of antidepressants called monoamine oxidase inhibitors (MAOIs).
