An October 2010 issue of Neurology, from the American Academy of Neurology, published findings from a small, preliminary study conducted by the Karolinska Institute in Stockholm, Sweden.
According to researchers, “vitamin B12 and related metabolites may have a role in Alzheimer’s disease” – an important finding since a vitamin B12 deficiency is a “common condition” in the elderly.
Investigating homocysteine levels (if elevated, associated with strokes) and levels of an active protein in B12 (holotranscobalamin) that can reduce homocysteine blood level. Their seven-year follow-up revealed that with every small increase of homocysteine, the risk for Alzheimer’s shot up 16%.
More study is needed, yet a case is being made for a diet rich in vitamin B12 to ward off neurodegenerative disease.
