Low vitamin B-12 status and risk of cognitive decline in older adults.
Clarke R et al.

Vitamin B(12) and folate in relation to the development of Alzheimer's disease.
Wang HX et al.
Neurology. 2001;56:1188-94.
In 370 elderly men and women followed over 3 years, low serum vitamin B12 (<150 pmol/L) or folate (<10 nmol/L) levels were associated with a doubling of the risk of developing Alzheimer's disease.

Morris MC et al.
J Neurol Neurosurg Psychiatry. 2004;75:1093-9
