Since it was shown that increased oxidative stress is applied in the pathogenesis of Alzheimer's disease, there were discussions about the therapeutic use of antioxidants. Until now, there are several studies which show that the degree of lipid peroxidation is higher not only in brain tissue, but also plasma and cerebrospinal fluid of patients with Alzheimer's disease. Correspondingly, it is found in these patients and decreased levels of antioxidants, which are capable of preventing lipoperoxidation.

High dose combination of vitamins E and C reduces the risk of developing Alzheimer's disease. They may not however be used in multivitamin tablets, otherwise everybody gets their antioxidant capacity, which effectively fight free radicals in the body. U.S. scientists suggest that people receiving high doses of vitamin E and C were 78% lower risk of development of negative effects associated with the disease of old age.

Artificial enrichment of foods with folic acid may reduce the number of deaths from heart attack and stroke by three to four percent per year. Researchers analyzed death caused by heart attack and stroke in people older than forty years. The research covered the period before the introduction of compulsory artificial enrichment of foods with folic acid - fortification in the U.S. and Canada, namely the period from 1990 to 1997, and years after its introduction - from 1988 to 2002.

Vitamin B12, which is found in foods of animal origin, helps restore nerve cells and formation of DNA. A new study of English experts now demonstrated that its deficiency also accelerates atrophy (shrinkage) of the brain during aging. Researchers from Oxford University followed 107 volunteers aged 61 to 87 years, broken down by injection of vitamin B12 in the diet.

Research shows that regular consumption of folic acid reduces the risk of stroke. Dieticians recommend to the British government to approve its addition to commercially produced flour. Already known that folic acid is essential for pregnant women because it protects the fetus against birth defects.

Current research in the journal Circulation * indicates that the fortification of foods with folic acid may reduce the number of deaths from heart attack and stroke by 3 to 4 percent per year. Researchers analyzed death due to heart attack and stroke in people older than 40 years. The research covered the period before the introduction of mandatory fortification of foods with folic acid in the USA and Canada (1990 -1997) as well years after its introduction (1998-2002).

It is believed that vitamin B-12 and folic acid are involved in the pathogenesis of dementia and Alzheimer's disease (AD), whereas the absence of both of these vitamins may have serious neurological effects, including confusion and memory loss. This review briefly summarizes the main studies on vitamin B12, folic acid and AD in the literature. Studies from various countries show that low levels of vitamin B12, or its absence is more frequently found in patients with AD than in patients without dementia.

A new study by American scientists showed that the consumption of large amounts of folic acid, which is included citrus fruits and green vegetables, reduces the risk of Alzheimer's disease. Experts from the U.S. National Institute on Aging followed for seven years, the composition of the diet in the elderly. Then come to the conclusion that those who consumed the recommended dose of folate, which are derivatives of folic acid contained in vegetables, reduce the risk of the aforementioned diseases.

Lack of folate, also known as vitamin B9, can triple the risk of dementia in old age. Informed about the study published in the journal British Medical Association Journal of Neurology, Neurosurgery and Psychiatry. A team in South Korea measured the incidence of folate in 518 elderly people, and none of them has shown no signs of dementia.

Some sources say that polio can be treated with vitamin C. Reference is made to work Jungebluta, dated around 1935. This work describes the weakening of virus in a test tube outside the body by vitamin C.
