Recovery of neurologic dysfunction with early intervention of vitamin B12.
A patient developed numbness and tingling in distal extremities with subsequent weakness. Evaluation revealed B12 deficiency. She had evidence of myelopathy on imaging studies and polyneuropathy on electrodiagnostic testing. Treatment with B12 caused remittance of symptoms and resolution/improvement of abnormalities found on the imaging and electrodiagnostic studies. This case demonstrates that early intervention with B12 supplementation can cause reversal of both central and peripheral nervous system dysfunction.
