Plasma Concentrations of Vitamins A and E and Carotenoids in Alzheimer's Disease
This study investigated blood levels of vitamins and carotenoids in Alzheimer's patients. Data from patients with Alzheimer's disease were compared with data from participants without the disease. The results showed that Alzheimer's patients had significantly lower levels of vitamin A, vitamin E and beta-carotene. In view of this result, the present study is a further indication of the importance of vitamins in preventing or slowing brain diseases like Alzheimer’s. Further details can be found in the study.
