Aging, Lack of Vit. B12 linked to Brain Shrinkage

A University of Oxford Study published in ‘Neurology’ tested 107 men and women aged avg 73 scanned with M.R.I. showing  no brain impairment were followed for 5 years. Blood tests were used to measure the levels of Vitamin B12. The group with the lowest levels of  Vitamin B12 lost twice as much brain volume as those with the highest levels.  The difference was significant even after allowing for initial brain size, age, sex, education, cognitive test scores and various measures of blood chemistry.  Other studies suggest that the elderly develop deficiency at a higher measure B12 level. Pending the results of further trials it is suggested that diet in the elderly needs to be well managed to ensure better than adequate B12 levels.
