A new study links vitamin B12 deficiency to brain shrinkage and memory problems in older adults.

The study involved 121 adults age 65 and older who are part of the ongoing Chicago Health and Aging Project.

Researchers tested participants for thinking skills and blood levels of vitamin B12, as well as for the presence of blood markers that accumulate when the body does not have enough B12. Four to five years later they had MRI brain scans.
