We explored the role of vitamin B12 in managing neuroinflammation after an ischemic stroke. Through preclinical studies, we observed that vitamin B12 effectively influenced microglial cells, which are key to the brain's immune response. This treatment promoted important cellular processes, leading to reduced brain damage and better neurological outcomes. However, when microglia were depleted before stroke, the positive effects of vitamin B12 disappeared. Overall, while vitamin B12 shows promise in enhancing recovery post-stroke, its impact hinges on these immune cells.

We explored the connection between vitamin B12 levels and heart rate variability (HRV) in patients who have experienced ischemic stroke. The study involved a look back at the medical records of 87 patients from January 2015 to December 2022. Each patient had their serum vitamin B12 levels measured and underwent 24-hour heart rhythm monitoring.
Our findings revealed a significant relationship between vitamin B12 status and HRV, particularly in the frequency domain, which is a crucial area for understanding autonomic function. The statistical analysis indicated that vitamin B12 levels are a substantial predictor of HRV parameters, suggesting that lower levels of this vitamin may coincide with poorer heart rate regulation in stroke patients.
This research highlights the potential impact of vitamin B12 on maintaining heart health in those who have suffered strokes. By demonstrating that vitamin B12 status could be linked to autonomic dysfunction, we provide valuable insights into how maintaining proper vitamin levels might aid recovery and improve overall cardiovascular health in these patients.

We examined whether high levels of vitamin B-12 affect the risk of stroke, with a particular focus on gender differences. Utilizing data from the Korean Genome Epidemiology Study, we assessed stroke occurrence in relation to vitamin B-12 plasma levels using various statistical methods.
Our findings indicated that while excessive vitamin B-12 did not significantly increase overall stroke risk, it was linked to a higher risk in males. This suggests that the effects of vitamin B-12 might vary based on sex, making it a noteworthy consideration in stroke research.

B12 deficiency mimics stroke symptoms
We examined a fascinating case involving a 53-year-old woman who showed atypical signs of vitamin B12 deficiency, resulting in gait instability that mimicked stroke symptoms. Neuroimaging confirmed spinal cord damage typical of subacute combined degeneration, while lab tests showed low B12 levels.
Despite the absence of classic symptoms, the patient responded remarkably well to immediate B12 treatment, restoring her gait stability and neurological functions. This emphasizes the importance of recognizing varied symptoms of B12 deficiency and the need for swift intervention.

We explored the relationship between vitamin B12, folate, and plasma total homocysteine levels in predicting the risk of acute ischemic stroke. This study involved 259 stroke patients and an equal number of healthy control participants.
Through careful analysis, we found that vitamin B12 acted as an independent risk factor for ischemic stroke. Additionally, the model combining vitamin B12, folate, and homocysteine levels demonstrated the best diagnostic value, particularly for small vessel disease cases.
Overall, our research indicates a significant connection between vitamin B12 levels and stroke risk.

We examined how different dosages of B-vitamins, specifically folic acid, vitamin B12, and vitamin B6, affect stroke prevention. Our review included 14 studies with over 76,000 participants and assessed the risk of stroke after supplementation.
We discovered that in areas lacking sufficient folic acid fortification, this B-vitamin combination significantly lowered stroke risk. Optimal doses were identified at 0.8 mg/d for folic acid and 0.4 mg/d for vitamin B12. However, in regions with adequate fortification, no benefit was observed from supplementation.

We delved into the relationship between serum vitamin B levels and the risk of ischemic stroke by examining hospitalized patients at a major medical center. Our study involved over 2,200 patients and analyzed data using logistic regression, adjusting for various factors.
The results indicated that low vitamin B levels could signal an increased risk for ischemic stroke. Specifically, patients with lower serum vitamin B showed a higher prevalence of stroke, while higher levels appeared to lower that risk. These findings suggest that monitoring and supplementation of vitamin B could potentially benefit stroke outcomes.

Vitamin B12 deficiency and stroke
We focused on understanding how vitamin B12 levels relate to stroke severity and outcomes. In a study involving 75 patients with ischemic stroke and 75 matched controls, we found stroke patients had notably lower vitamin B12 levels and higher homocysteine levels than the control group.
Specifically, those with the lowest B12 levels faced more severe strokes and worse functional outcomes after discharge. Although this study shows a clear connection, further research is needed to determine if B12 supplementation can genuinely reduce stroke risk or improve recovery.

We examined data from over 8,000 adults in the National Health and Examination Survey to understand how vitamin B levels and homocysteine relate to stroke risk.
Our findings revealed complex relationships: higher levels of homocysteine were positively associated with stroke prevalence, while vitamin B6 and folate showed L-shaped trends.
Interestingly, vitamin B12 had a U-shaped relationship with stroke, suggesting both low and high levels might be concerning. These results indicate a need for balanced vitamin levels in stroke prevention.
