According to this article, a really high dose of Vitamin E (2000 i.u.’s per day) may increase the life span of those suffering from Alzheimer’s Disease. However, researchers are surprised, given that recent research showed doses of Vitamin E that high actually increased mortality. But not, apparently, for this population. From the article:
"The concern is that vitamin E will actually have a harmful affect, because a recent review of prior studies found that it had a slightly negative impact on mortality," said study author Valory Pavlik, an associate professor with the Alzheimer's Disease and Memory Disorders Center at Baylor College of Medicine in Houston.
"But I think -- to our surprise -- the message really is that for the treatment of Alzheimer's in clinical practice, we did not find evidence that high doses of vitamin E reduced survival," she said. "In fact, patients who took vitamin E seemed to live longer, particularly when they took it in combination with a cholinesterase inhibitor."
Again, I read and post about stuff like this because I find it interesting, as well as important given the trends of our demographics. The study determined that the net increase in life span was 26%, but they also stated that dosage may not be necessary. In addition, the authors cautions that dosage is not appropriate for the average person. Ultimately, the researchers argue further research is necessary to sort of these conflicting findings.
