In the August 2008 issue of the Journal of Neurology, Neurosurgery, and Psychiatry , investigators from Korean reported that onset of dementia is associated with decreasing folate levels, as well as increasing homocysteine and vitamin B12 levels, in the blood .

Although prior research had shown associations among low folate levels, high homocysteine levels, and dementia, it was not known whether the abnormal folate and homocysteine levels were a cause or effect of dementia. In this study, the researchers found that lower folate levels seemed to be a predictor of dementia.

The researchers conclude that, although further research is needed to clarify this complex relationship, health care providers should keep a close watch on the nutritional status of people with dementia.
