BackgroundVitamin B deficiency and elevated total plasma homocysteine have been associated with cognitive impairment and dementia in later life, although it is unknown if treatment with these vitamins improves cognitive outcomes.ObjectivesThe objectives of this study were to examine the efficacy of treatment with vitamin B12, vitamin B6, or folic acid in slowing cognitive decline amongst older adults with and without cognitive impairment.MethodsWe summarized findings from previous systematic… 

Effects of Vitamin B12 Supplementation on Cognitive Function, Depressive Symptoms, and Fatigue: A Systematic Review, Meta-Analysis, and Meta-Regression

It is found that vitamin B12 supplementation is likely ineffective for improving cognitive function and depressive symptoms in patients without advanced neurological disorders and meta-regression showed no significant associations of treatment effects with any of the potential predictors.

B vitamins and prevention of cognitive decline and incident dementia: a systematic review and meta-analysis.

This meta-analysis supports that B vitamins can benefit cognitive function as measured by Mini-Mental State Examination score changes and indicates that higher intake of dietary folate, but not B12 or B6, is associated with a reduced risk of incident dementia in non-dementia aged population.

The preventive efficacy of vitamin B supplements on the cognitive decline of elderly adults: a systematic review and meta-analysis

Vitamin B supplements might delay or maintain the cognitive decline of elderly adults and should be considered as a preventive medication to MCI patients or elderly adults without cognitive impairment, according to the results of meta-analysis.

Positive effects of folic acid supplementation on cognitive aging are dependent on ω-3 fatty acid status: a post hoc analysis of the FACIT trial.

It is revealed that the efficacy of folic acid treatment on cognitive functioning is dependent on the ω-3 fatty acid status, and the importance of a personalized approach is emphasized.

Influences of Vitamin B12 Supplementation on Cognition and Homocysteine in Patients with Vitamin B12 Deficiency and Cognitive Impairment

Vitamin B12 supplementation resulted in improved cognitive function, at least in the short term, in patients with vitamin B12 deficiency, and this is a multi-center, open-label, single-arm study.

The dihydrofolate reductase 19-bp deletion modifies the beneficial effect of B-vitamin therapy in mild cognitive impairment: pooled study of two randomized placebo-controlled trials

The data indicate that the beneficial effects of B vitamins including FA on cognitive function are only apparent in those with ins/ins genotype, i.e. relatively better preserved DHFR activity.

The effects and potential mechanisms of folic acid on cognitive function: a comprehensive review

According to data obtained from the review, it seems that folic acid supplementation may improve cognitive function by decreasing homocysteine (Hcy), vascular care, attenuating inflammatory status, modification of cerebral folic Acid deficiency, and antioxidant responses.

Dose-response relationship in non-pharmacological interventions for individuals with mild cognitive impairment: A systematic review and meta-analysis of randomised controlled trials.

The research summarised the evidence to guide the best prescription of NPIs and helped clinicians design more effective interventions in individuals with MCI.

Low folate predicts accelerated cognitive decline: 8-year follow-up of 3140 older adults in Ireland

Low folate was associated with accelerated decline in cognitive function and is an important marker for cognitive decline among older people, and lower concentrations of folate may have differential relationships with cognitive domains.

The effects of twenty-one nutrients and phytonutrients on cognitive function: A narrative review

Background and Aim: Brain health is becoming more important to the average person as the number of people with cognitive impairments, such as Alzheimer’s disease (AD), is rising significantly. The



Effect of homocysteine lowering treatment on cognitive function: a systematic review and meta-analysis of randomized controlled trials.

Elevated total plasma homocysteine has been linked to the development of cognitive impairment and dementia in later life and this can be reliably lowered by the daily supplementation of vitamin B6,

Efficacy of Vitamin B Supplementation on Cognition in Elderly Patients With Cognitive-Related Diseases

Taking together, vitamin B supplementation was effective in reducing serum homocysteine levels, however, it did not translate into cognitive improvement, indicating that the existing data on vitamin B-induced improvement in cognition by lowering homocy steine levels are conflicting.

Effects of vitamin B-12 supplementation on neurologic and cognitive function in older people: a randomized controlled trial12

Results of the trial do not support the hypothesis that the correction of moderate vitamin B-12 deficiency, in the absence of anemia and of neurologic and cognitive signs or symptoms, has beneficial effects on neurologic or cognitive function in later life.

Effects of homocysteine lowering with B vitamins on cognitive aging: meta-analysis of 11 trials with cognitive data on 22,000 individuals12345

Homocysteine lowering by using B vitamins had no significant effect on individual cognitive domains or global cognitive function or on cognitive aging.

A trial of B vitamins and cognitive function among women at high risk of cardiovascular disease.

Combined B vitamin supplementation did not delay cognitive decline among women with CVD or CVD risk factors, and the possible cognitive benefits of supplementation amongWomen with a low dietary intake of B vitamins warrant further study.

Homocysteine-Lowering by B Vitamins Slows the Rate of Accelerated Brain Atrophy in Mild Cognitive Impairment: A Randomized Controlled Trial

The accelerated rate of brain atrophy in elderly with mild cognitive impairment can be slowed by treatment with homocysteine-lowering B vitamins, and is associated with a lower final cognitive test scores.

High-dose B vitamin supplementation and cognitive decline in Alzheimer disease: a randomized controlled trial.

Although the vitamin supplement regimen was effective in reducing homocysteine levels, it had no beneficial effect on the primary cognitive measure, rate of change in ADAS-cog score during 18 months, and this regimen of high-dose B vitamin supplements does not slow cognitive decline in individuals with mild to moderate AD.

Vitamins B12, B6, and folic acid for cognition in older men

The daily supplementation of vitamins B12, B6, and folic acid does not benefit cognitive function in older men, nor does it reduce the risk of cognitive impairment or dementia.

Investigating whether daily supplementation with high doses of oral vitamin B-12 alone or in combination with folic acid has any beneficial effects on cognitive function in persons aged >/=70 y with mild vitamin B -12 deficiency found it does not improve cognitive function.
