does vitamin b12 deficiency cause brain and nerve problems? can it cause foot drop dealing with the peroneal nerve?

Yes: It is infamous for this. And the damage can be permanent. The individual perineal nerve is less likely to be involved than a stocking-glove distribution. “Vegetarian’s neuropathy” is all too common in folks who do not supplement.
