Participants who did not have dementia performed significantly better on cognitive tests than did participants who did not take the vitamins. Antioxidant protection, Vitamins E and C are considered two of the best antioxidants, do protect memory.
Antioxidants help protect brain cells from free radicals, the toxic byproducts of oxidation.
Previous Vitamin E research has shown that Vitamin E slows progression of functional decline in patients with moderately advanced Alzheimer's disease. About half of the patients improved in a recent University of Pittsburgh study using brain cell transplants. The transplant method was shown to be safe. Dr. Douglas Kondziolka, a professor of neurological surgery at the University of Pittsburgh, led the study. He stated the transplantation was a brand-new area of neuroscience and, in the first study, safety was emphasized.
