Abstract

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).
