We explored the effects of vitamin B12 deficiency on neurological health in elderly patients. In a case study involving two patients, we observed that even with normal B12 levels, symptoms like fatigue and cognitive impairment persisted, especially in those with significant medical histories.
Treatment with hydroxocobalamin injections led to notable improvements in both patients’ cognitive and motor functions. This highlights the importance of recognizing vitamin B12 deficiency in older adults, even when traditional tests suggest adequate levels.

We explored a case involving a 41-year-old woman who experienced unstable walking due to a vitamin B12 deficiency. Her symptoms were related to subacute combined degeneration of the spinal cord, which affected her nerve health.
After starting vitamin B12 treatment, we observed significant improvements in her limb weakness and overall muscle strength, recovering to a notable level. This case highlights the critical importance of early diagnosis and intervention for vitamin deficiencies to prevent irreversible nerve damage.

We investigated how methylcobalamin, a form of vitamin B12, affects neuropathy by exploring its pharmacokinetics in rats. Our study utilized a straightforward method to assess the levels of methylcobalamin in the bloodstream using just a drop of plasma.
Under controlled conditions, we extracted methylcobalamin from rat plasma and developed an efficient assay using liquid chromatography and tandem mass spectrometry. The results showed that methylcobalamin was effectively quantified even at low concentrations, demonstrating the robustness of our approach.
We administered methylcobalamin through various routes—intravenous, intramuscular, and subcutaneous—to evaluate its bioavailability. Our findings revealed that methylcobalamin demonstrates high bioavailability, particularly after intramuscular and subcutaneous injections, significantly supporting its potential effectiveness in treating peripheral neuropathies.
Overall, this study suggests that methylcobalamin could be a valuable treatment option for neuropathy, providing a basis for further research into its benefits for those suffering from nerve-related conditions.

We examined a unique case involving a 33-year-old woman with HIV who experienced sudden vision loss linked to vitamin B12 deficiency. Initially treated with B12 tablets for severe peripheral neuropathy, her condition escalated to optic neuritis. Upon diagnosis, she received prednisolone and daily B12 injections. After five months of this treatment, she reported a significant recovery in her vision. This case highlights the importance of recognizing vitamin B12 deficiency’s potential eye-related symptoms, especially in patients with underlying health conditions like HIV, to ensure timely intervention.

We examined the case of a 40-year-old woman suffering from a decade of vague symptoms, including pain and cognitive issues, before being diagnosed with vitamin B12 deficiency due to pernicious anemia.
Despite low B12 levels showing no typical signs of anemia, the use of parenteral B12 treatment led to her neurological improvement. This case reinforces how vital it is to recognize B12 deficiency even when classic symptoms aren't present, ensuring timely treatment to avoid serious complications.

We explored the effectiveness of steroid treatment versus vitamin B12 therapy for improving diabetic ocular nerve palsy. Our study involved fifty participants, with half receiving steroids and the other half vitamin B12 injections.
After assessing ocular movements at various intervals, we found that the vitamin B12 group experienced a greater improvement than the steroid group. This suggests that vitamin therapy could play a significant role in enhancing eye movement and addressing underlying nutritional deficiencies.
Ultimately, vitamin B12 therapy presents a promising option for those with diabetic mononeuropathies.

We explored the connection between nitrous oxide use and vitamin B12 deficiency, specifically focusing on neurological issues like peripheral neuropathy. Through a reported case of nitrous oxide-induced subacute combined degeneration of the spinal cord, we identified a functional B12 deficiency despite normal serum levels.
The good news is that treatment with intramuscular vitamin B12 showed notable clinical improvement. This suggests that B12 may be beneficial for those with similar deficiencies related to nitrous oxide exposure.
