Brain shrinkage halved by taking B vitamins, Alzheimer's researchers say
"This is a very dramatic and striking result. It's much more than we could have predicted," said trial co-leader David Smith of Oxford University's department of pharmacology. "It is our hope that this simple and safe treatment will delay development of Alzheimer's in many people who suffer from mild memory problems."
The two-year clinical trial is believed to be the largest to date studying the effects of B vitamins on individuals with “mild” cognitive impairment. Researchers said about half of those diagnosed with mild cognitive impairment develop Alzheimer's within five years. B6 and B12 vitamins have been found to control levels of an amino acid in the blood that has links to higher risks of developing Alzheimer's, experts explained.
