Vitamin B deficiency may cause vascular cognitive impairment

Researchers at Tufts University have discovered that a lack of vitamin B may cause cognitive impairment, such as dementia, in patients who have suffered from heart attacks.

“Metabolic impairments induced by a diet deficient in three B-vitamins – folate, B12 and B6 – caused cognitive dysfunction and reductions in brain capillary length and density in our mouse model,” says lead author Aron Troen.

Scientists fed laboratory mice a diet low in vitamin B. These mice demonstrated a significant decrease in spatial learning and memory when compared with those who received a normal diet. The B-vitamin deficient mice also showed higher levels of homocysteine, a protein that is commonly associated with an increased risk of cognitive impairment.

The team of researchers hope that their study will help define more precisely the underlying mechanisms involved with cognitive decline.

Those interested in increasing their B-vitamin in take may want to consider taking dietary supplements like those offered by Dr. Newton’s Naturals.

Vital B-100 from Dr. Newton’s Naturals contains several B-vitamins, including B-1, B-6 and B-12. Regular intake may help promote a healthy immune system and regulate cholesterol.
