Results of the study revealed that patients who received the vitamin E had a 19% reduction in functional decline, compared with patients who received the placebo. The researchers say this is the equivalent to a "clinically meaningful delay in progression" of 6.2 months.
Furthermore, the investigators found that patients who received vitamin E needed 2 hours less assistance from a caregiver each day.
They note that memantine and a combination of both memantine and vitamin E demonstrated no clinical benefit for the patients.
The researchers point out that functional decline as a result of Alzheimer's disease is increasingly recognized as having a significant impact on a patient quality of life, as well as putting a strain on social and economic costs.
