This study of Alzheimer’s and multi-infarct dementia patients, compared to nondemented elderly controls, found that in the 20 Alzheimer’s and multi-infarct dementia patients there were significantly lower levels of vitamin E and beta-carotene than controls. Vitamin A was significantly reduced only in Alzheimer’s disease patients. Vitamins A and E and the carotenoids act as free radical scavengers and their deficiency may increase the degenerative neurologic process in the brain and thereby exacerbate dementia.
