Lack of Vit B12 can shrink brain

A new study has found that elderly individuals with low level of vitamin B12 in their blood are at a higher risk of brain shrinkage and losing their cognitive skills.

Lead author Christine C. Tangney, PhD, of Rush University Medical Center in Chicago, and her colleagues looked at 121 people age 65 and older living on the south side of Chicago.
Their blood was drawn to measure levels of vitamin B12 and B12-related metabolites that can indicate a B12 deficiency.

The participants also took tests measuring their memory and other cognitive skills.
An average of four-and-a-half years later, MRI scans of the participants' brains were taken to measure total brain volume and look for other signs of brain damage.    Read More
