Which vitamin deficiency is often associated with neurological symptoms?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin B6
• D. Vitamin B12

Answer: (D)

Vitamin B12 deficiency is often associated with neurological symptoms due to its crucial role in the formation of myelin, the protective sheath surrounding nerves. When there is an insufficient amount of vitamin B12, it can lead to neurological issues such as numbness, tingling in the hands and feet, memory disturbances, and cognitive dysfunction. This vitamin is also essential for red blood cell production and DNA synthesis, but its involvement in neurological health is particularly notable. In cases of vitamin B12 deficiency, the lack of myelin can impair nerve signal transmission, leading to a range of neurological manifestations. Additionally, vitamin B12's role in homocysteine metabolism links its deficiency to neurological and cognitive decline. This makes it a critical focus when evaluating patients presenting with neurological symptoms, particularly in populations at risk for malnutrition or absorption issues, such as the elderly or those with gastrointestinal disorders.
