title: Reversibility of neurological deficits in vitamin B12 deficiency.
abstract: A female patient with subacute neurological deficits secondary to an hereditary vitamin B12 deficiency was repeatedly examined clinically and neurophysiologically. It is concluded that neurological normalization after treatment with vitamin B12 also occurs within the CNS. Such normalization takes place soon after initiating treatment and probably reflects other neuronal mechanisms that remyelination, i.e. recovery from conduction block in fast somatosensory pathways and/or improvement of synaptic transmission.
