B12: B12 deficiency is associated with neuropathies and non-specific neurological symptoms such as irritability, fatigue, depression, and psychosis. It is not associated with migraine headaches, per se.

Vitamin B12 deficiency causes itching, what can I do?

Decisive treatment: Don't know if it's the cause of your itch, if you are B12 deficient, either from an ill-advised experiment with a vegetarian lifestyle without supplementation, or pernicious anemia or harboring a fish tapeworm, you had better start getting supplemented now and continuing or you are going to end up with brain damage. Forgive my frankness, and i hope your physician made this clear as well.

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.

No: No, but b vitamins are important for healthy organ development in early pregnancy. It is important to take supplemental folic acid, and consider a b complex vitamin as well, to support normal organ development if you are reproductive aged woman.

Who is at risk of vitamin B12 deficiency?

Many: The classic B12 deficient people are severe alcoholics and vegan type vegetarians. Obviously, the reason for the deficiency is different in the two groups. Vegans simply don't eat enough B12 containing foods. Alcoholics are a bit more complicated than that.
