Summary
In five patients with peripheral neuropathy due to vitamin B12 deficiency, electrodiagnostic studies demonstrated severe reduction in sensory nerve conduction velocities compatible with a demyelinating disorder affecting sensory nerve fibres. It is suggested that in some patients lack of vitamin B12 may cause primary sensory demyelinating neuropathy.
