Can a Vitamin B12 Deficiency Cause Neurological Symptoms?
Yes, vitamin B12 deficiency can cause serious neurological symptoms affecting both the central and peripheral nervous systems. B12 is essential for myelin synthesis, the protective coating around nerve fibers. Without adequate B12, nerve damage occurs progressively. Common neurological symptoms include numbness and tingling in hands and feet, difficulty walking, memory problems, confusion, and depression. In severe cases, patients may experience irreversible spinal cord damage called subacute combined degeneration. Studies show that neurological symptoms can appear even before anemia develops, making early detection crucial. The elderly are particularly vulnerable, with up to 15% experiencing B12 deficiency. Prompt treatment with B12 supplements can reverse many symptoms if caught early, but delayed treatment may result in permanent nerve damage.
