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.

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. So, do try to improve your diet and even supplement nutrients that are hard to get enough of. See a professional for ocd treatment too.

Are the neurological symptoms from vitamin B12 deficiency reversible?

Not Always: The progression of neurologic complications is generally gradual. They are not always reversible with treatment of vitamin B12 deficiency, especially if they have been present for a long time.
