Researchers from Baylor College of Medicine report that Vitamin E supplements
improve the survival of people suffering with Alzheimer’s disease. "Vitamin
E has previously been shown to delay the progression of moderately severe Alzheimer's
disease. Now, we've been able to show that vitamin E appears to increase the
survival time of Alzheimer's patients as well," said lead author Valory
Pavlik, PhD. In an interview with NutraIngredients.com, Dr. Pavlik indicated
that the results of the study, a long-term follow-up of an Alzheimer's disease
patient cohort, are in-line with a randomized, placebo-controlled trial reported
recently in the New England Journal of Medicine (1997, Vol. 336, pp. 1216-22),
which showed a beneficial effect of vitamin E (2000 IU total per day) in Alzheimer’s
patients.
Dr. Pavlik and co-workers followed 847 people with Alzheimer's disease (average
age 73.5, with 67 per cent being female) for an average of 4.9 years. The standard
recommendation for the patients was to consume 2000 IU of vitamin E daily from
commercially available supplements "The daily amount of vitamin E taken
by patients in this study was much higher than what is currently recommended
for the general population," said Pavlik. Consumption of the vitamin, either
with or without a cholinesterase inhibitor, was associated with a 26 per cent
reduction in all-cause mortality that those who didn't take vitamin E, reported
Dr. Pavlik.
In addition, the study found vitamin E plus a cholinesterase inhibitor may be
more beneficial than taking either agent alone. "Our findings show that
people who took a cholinesterase inhibitor without vitamin E did not have a
survival benefit," said Pavlik. The data was presented at the American
Academy of Neurology 60th Anniversary Annual Meeting on 15 April.
