What are the cognitive risks associated with vitamin B12 deficiency in the elderly? Evidence-based answer: Whether serum vitamin B12 levels in older adults are associated with cognitive changes is unclear. However,elevated levels of methylmalonic acid, a B12 metabolite that reflects low vitamin B12 function, are more consistently associated with cognitive decline (SOR: B, systematic reviews of longitudinal studies).
