A new Swedish study has found that high serum levels of vitamin E may be associated with a decreased risk of Alzheimer’s disease among the elderly. The findings suggest that the nutrient may help older individuals stave off various cognitive decline disorders, according to the researchers.
For the study, a team of investigators from the Aging Research Center in Stockholm recruited 232 dementia-free patients who were over the age of 80. After six years of follow-up, lead author Francesca Mangialasche and her colleagues discovered that 57 respondents had developed Alzheimer’s disease during the course of the research.
When analyzing the blood work of each participant, the researchers found that those with the highest levels of all eight natural vitamin E components had a 45 percent to 54 percent lower risk of being diagnosed with Alzheimer’s disease compared with patients who had the lowest levels.
After Mangialasche accounted for various risk factors associated with Alzheimer’s disease, the correlation remained.
"Our findings need to be confirmed by other studies, but they open up for the possibility that the balanced presence of different vitamin E forms can have an important neuroprotective effect," she said.
