Why Does Vitamin B12 Deficiency Cause Neurological Symptoms
Required by nerves: This co-factor is needed by the nerves to stay healthy. Each nerve cell has a self repair system that relies on a variety of nutrients in our diet to provide the needed material to keep the walls intact and the cell working. Lack of B12 eventually causes that repair system to start breaking down and nerve cells malfunction or degenerate, leading to neurologic symptoms. ...Read moreSee 1 more doctor answer
B12 deficiency can be due to a lack of absorption or intake from diet. Since B12 is primarily found in animal products (e.g., dairy, egg, meat, etc.) vegetarians are more at risk. A deficiency is suspected when rbcs increase in size (e.g., high MCV and/or MCH in cbc) and can cause megaloblastic anemia. Symptoms can include fatigue and neuropathy. It is best corrected with ...Read more
Not at all likely: Almost no chance of a direct link, but... We do know that: 1) the b vitamins are important to nervous system functioning. 2) B12 can make a noticeable difference in how good one feels. 3) deficiencies are (by definition) good to correct.

Yes: In the early 19th century, scientists noted weakness and numbness with B12 deficiency. Recently, B12 has been shown to upregulate neurotrophic factors (chemicals [cytokines] that help nerve cells grow) & downregulate neurotoxic factors (chemicals that break down nerve cells). In other words, B12 helps nerve cells grow and prevents their destruction by naturally occurring brain chemicals. ...Read moreSee 1 more doctor answer
Not clear: No clear evidence for the causal-effect relationship between the two. PA is an autoimmue-mediated destruction of parietal cells in stomach, resuling in impairmnent of B12 absorption. Certainly it is possible that pernicious anemia may co-exist or exacerbate duodenitis via immune process or loss of balance in duodenal fluid, or anemia. But the causal-effect relationship is not well established. ...Read moreSee 2 more doctor answers
