In brief: Yes.

Pernicious anemia is the most common reason for unexpected B12 deficiency.
Lack of B12 can cause both anemia and neurological damage. The latter includes numbness, gait problems, and dementia. The neurological findings can occur before there is any anemia, or vice versa. The anemia will reverse with treatment. The neurologic problems may not correct completely with B12 treatment.
