In the study the effect of vitamin B6 in pregnant and lactating women,  researchers found that recommended dietary allowance of vitamin B6 may have a strong effect in improved cognitive and brain development as the nutrient is an essential cofactor in the developing central nervous system of fetus.

Dr. Guilarte TR, at the study said, " Recent work in animal models suggests that vitamin B6 deficiency during gestation and lactation alters the function of N-methyl-D-aspartate receptors, a subtype of receptors of the glutamatergic neurotransmitter system thought to play an important role in learning and memory".

Other, in the study of nutrient effect on cognitive impairment, patients with AD expressed a 50% deficits of various nutrients, including folic acid, vitamin B12, B6, C, E, A, D, K, beta carotene and omega 3 fatty acids.

Interestingly, In the investigation of whether baseline folate, vitamin B-6, and/or vitamin B-12 intake, alone or in combination, are associated with incident MCI/probable dementia among older women containing 7030 Postmenopausal women free of MCI/probable dementia at baseline in the Women's Health Initiative Memory Study, after carefully examine the returned questionnaire, researchers indicated that vitamin B6 showed no effect in improved symptoms of dementia in this group of women.
