A member asked:
For foot drop from a b12 deficiency, is the axon or myelin covering most often impacted?
6 doctors weighed in across 2 answers
Foot Drop: Most often is is the myelin sheath or insulation that is impacted. If the axons are effected it takes longer to recover if the causative reason is addressed. At about the 3 week mark after the occurrence it is easy to document the actual injury and extent with electrodiagnostic testing(ncs/emg). This would tell if demyelinating, axonal or combination of the two. This can help define prognosis.
