Pervasive B12 Deficiency Affects Millions
"B12 deficiency is common in elderly patients. One study revealed a prevalence of 12 percent among elderly people. Other studies, focusing on those who are in institutions or who are sick and malnourished, have suggested a higher prevalence of 30 percent to 40 percent. Unfortunately, B12 deficiency is often unrecognized because the clinical manifestations can be very subtle. In fact, one of its manifestations -- mild memory loss -- can mimic the early stages of dementia."
