What causes Alzheimer’s Disease? No one knows the answer. But an article in the Journal, “Dementia and Geriatric Cognitive Disorders” claims there’s an important link between heart disease and Alzheimer’s Disease. The link is atherosclerosis (hardening of arteries). What amazes me is that since it’s been shown vitamin C can reverse atherosclerosis in coronary arteries, why isn’t any one advocating its use in trying to prevent this catastrophic disorder?
