Aging itself leads to increases in MAO-B, and it could be that some of the changes that come with age are accelerated in the senile dementias. At least in the sense of protecting the brain from the maximum effect of these aging processes, it makes sense to ensure that your intake of B12 is adequate, the older you are.
I don't see any evidence that the same effect is seen in younger people. It may well be true, but there is no evidence. However, it does speak to the effectiveness of selegiline at low doses, as an augment strategy.....taking MAO-B out of the picture might be a really good thing, overall.
