Recently you may have seen headlines like “Vitamin E slows decline in patients with mild Alzheimer’s” or “There’s still no cure for Alzheimer’s disease, but the latest hope for slowing its progression is already on drugstore shelves.” They were referring to an article in the January 1, 2014 issue of the Journal of the American Medical Association (JAMA) announcing the results of the TEAM-AD VA Cooperative Randomized Trial of vitamin E and memantine (Namenda) for Alzheimer’s disease (AD).
The study attracted a lot of media attention. Most of the news reports I have seen were accurate and cautious, explaining the nuances of the study rather than suggesting that everyone should run out and buy vitamin E; but I wouldn’t be surprised to learn that a lot of readers ignored the fine print and did just that. It would be interesting to track sales of vitamin E and see if there was a bump following the publicity.
We know of no treatment that will delay, prevent or cure Alzheimer’s disease, or that affects the underlying disease process. It’s a tragic, frustrating disease that takes away the very things that make us who we are: memory and personality. It is affecting more and more people as the numbers of elderly increase. Available prescription medications are only modestly effective in slowing functional decline and delaying the need for institutionalization. They are expensive, they don’t help everyone, and when they do help, they only help for a limited time. It is very exciting to think an inexpensive vitamin could help patients with mild to moderate AD, but we must resist the temptation to read too much into this study. (more…)
