Large daily doses of B vitamins may protect vulnerable populations from the brain shrinkage and memory loss associated with Alzheimer’s disease, according to a study conducted by researchers from Oxford University and published in the journal Proceedings of the National Academy of Sciences in May.
The new findings came from a reanalysis of data originally collected in 2010 from 271 older adults suffering from mild cognitive impairment, a form of memory loss considered a potential precursor to Alzheimer’s disease. Although the brain naturally shrinks as we get older (about 0.5 percent per year), in people with mild cognitive impairment this shrinkage takes place twice as fast as usual. In Alzheimer’s patients, shrinkage takes place four times as fast as usual.
