Low Vitamin B12 in the Brain Affects Memory

Vitamin B12 plays a very important role in neurological function, affecting memory and balance when blood levels are low. A new study shows impressively low levels of B12 measured in the brain were related to decreased neurological function and memory impairment in the elderly, as well as those with autism and schizophrenia.

“These are particularly significant findings because the differences we found in brain B12 with aging, autism and schizophrenia are not seen in the blood, which is where B12 levels are usually measured.” said Dr. Richard Deth, Ph.D., professor of pharmacology at Nova Southeastern University’s (NSU) College of Pharmacy. “The large deficits of brain B12 from individuals with autism and schizophrenia could help explain why patients suffering from these disorders experience neurological and neuropsychiatric symptoms.”

Food Sources of Vitamin B12

What foods have the most Vitamin B12?

“…Meat, poultry, eggs, dairy products and wild-caught fish. Leafy green vegetables, beans and peas also provide some B vitamins, but if you eat an all vegetarian or vegan diet, vitamin B12 is one of the nutrients your body is most likely deficient in, as it is naturally present in foods that come from animals, including meat, fish, eggs, milk and milk products.” (From Dr. Mercola – his article is interesting in that he discusses in greater detail the effects of diminished B vitamins and elevated homocysteine for increased Alzheimers and brain shrinkage.)

Interestingly, Vitamin B12 is found mostly in animal proteins. Meat and dairy is good for you, and it is probably a good idea to find a vitamin supplement if you don’t eat much of either.

“Both autism and schizophrenia are associated with oxidative stress, which also plays an important role in aging, and oxidative stress may underlie the decreased brain B12 levels observed in this study.”

I hope the next studies will include the effects of taking antioxidants on levels of B12 in the brain, and individual sources of antioxidants effects. Wouldn’t it be interesting to find a particular fruit, vegetable, or even chocolate, to be extremely beneficial in diminishing oxidative stress in the brain?
