B vitamins slow brain changes in a subgroup of older people

Dementia researchers at the University of Oxford have released additional data from a clinical trial carried out in 2010, which suggested that high dose B vitamins could halve brain shrinkage in older people with memory problems. The new findings delve deeper into the data, linking B vitamin supplementation to slower rates of shrinkage specifically in areas of the brain affected in Alzheimer’s disease in people with high levels of homocysteine. The results are part-funded by Alzheimer’s Research UK and published online in the journal Proceedings of the National Academy of Sciences, USA.
