ALZHEIMER'S DISEASE, VITAMINS A, E AND CAROTENOIDS
"Plasma Concentrations of Vitamins A and E and Carotenoids in Alzheimer's
"Zaman, Z., et al, Age and Ageing, 1992;21:91-94."
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.
