Low vitamin B12 raises risk of dementia in the elderly: Study

According to a latest study the elderly with low levels of vitamin B12 in their blood may be more likely to develop problems with their thinking skills and have more brain shrinkage. The study points to a link between low B12 and early cognitive decline, a condition that often leads to dementia. Previous research has found that those people with high levels of vitamin B12 in their blood have lower levels of an amino acid called homocysteine, which some studies have linked to an increased risk of Alzheimer's disease, memory loss, and stroke.
