Of course, symptoms vary, and of course many being damaged by B12 deficiency are not anemic. That is what I have saying for years. That is why I have been bothering to do this. I don't what that was in response to.

Memory, other psychiatric problems, severe motor problems (and often resulting imbalance), etc. are central nervous system problems.

Pernicious anemia is not a form of B12 deficiency. Pernicious anemia is the inability to secrete intrinsic factor. Pernicious anemia has been known for many years now to be the primary cause of severe B12 malabsorption. If someone take lots of B12 and has been deficient for years, they will almost surely still lack intrinsic factor; thus, they still have "pernicious anemia."

Normal nerve function is necessary for normal muscle function.
