A deficiency of B-vitamins may cause vascular cognitive impairment, according to the latest Proceedings of the National Academy of Sciences study.
A new Proceedings of the National Academy of Sciences study says that deficiency of B-vitamins may cause vascular cognitive impairment.
Carried out by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University, the study made use of an experimental model to examine the metabolic, cognitive, and microvascular effects of dietary B-vitamin deficiency.
About Vitamin B-12
Vitamin B-12 is also known as cobalamine or cyanocobalamine, owing to the presence of the metal, cobalt. Cyanocobalamine is used in most supplements because it is readily converted to active forms of vitamin B-12 in the body.

He added: "Mice fed a diet deficient in folate and vitamins B12 and B6 demonstrated significant deficits in spatial learning and memory compared with normal mice."
The researchers noticed similar but less pronounced differences between normal mice and a third group of mice that were fed a diet enriched with methionine.
About Vitamin B-6
Vitamins play an equally important part in the synthesis of neurotransmitters. Neurotransmitters in the brain also help maintain good mood while keeping one's mental faculties sharp

Homocysteine is produced by the breakdown of a dietary protein called methionine. B-vitamins, including folate, vitamin B12, and vitamin B6, are required to convert homocysteine back to methionine, thereby reducing the blood concentration of homocysteine.

Folic Acid and B Vitamins Have No Beneficial Effects on the Heart
A new study has found that long-term supplementation of folic acid and vitamin B supplements do not protect women against heart disease and stroke.

"However, it has not been determined that homocysteine is directly responsible. Based on the findings of our study, we theorize that a deficiency of B-vitamins induces a metabolic disorder that manifests with high homocysteine, as well as cerebral microvascular dysfunction," said Troen.

He added: "These findings may indicate that microvascular changes mediate the association between high homocysteine levels and human age-related cognitive decline."
