what would symptoms of brain damage be from a vitamin b12 deficiency?

Why do you ask?: Numbness in the fingers and/or toes, and weakness in the legs are the symptoms usually reported in "vegetarian's myelopathy", which unfortunately is fairly common. How much damage to cognition has already happened isn't clear. In infants, permanent, severe mental disability has been produced by mothers who are b12-deficient and feeding only breast milk, neither supplementing. Please be smart.
