Which vitamin deficiency can present with neurological symptoms?

Vitamin B12 deficiency is known to present with a variety of neurological symptoms due to its crucial role in the maintenance of healthy nerve cells and the synthesis of DNA. When there is an inadequate amount of vitamin B12, individuals may experience symptoms like peripheral neuropathy, characterized by tingling, numbness, and balance issues. Additionally, vitamin B12 deficiency can lead to more severe outcomes like myelopathy and cognitive disturbances, including memory loss and confusion.

This deficiency often arises from inadequate dietary intake, particularly in individuals following strict vegetarian or vegan diets, or due to malabsorption issues seen in conditions like pernicious anemia and certain gastrointestinal disorders. Recognizing the neurological implications of vitamin B12 deficiency is essential for timely diagnosis and treatment to prevent lasting damage to the nervous system.

The other vitamins listed, while they may have various health implications, are not primarily linked to neurological symptoms in the same significant manner as vitamin B12. Vitamin A is important for vision and immune function, vitamin C is crucial for skin and connective tissue health, and vitamin D primarily impacts bone health and calcium regulation.
