(Newser) – Folic acid, already known to help prevent birth defects, may play a role in the development of dementia, the BBC reports. Elderly subjects with low levels of folate in their blood were three times more likely than people with normal levels to develop dementia, a South Korean study found . But whether dementia is a cause or effect of low folate levels isn't known.

The study tracked 518 people over 65 for 2 years. It builds on research connecting folic acid, a form of vitamin B, and Alzheimer’s disease. The results are "one further example of why it is so crucial for people to lead a healthy lifestyle with a balanced diet rich in B vitamins and antioxidants," said an expert.
