In the results of an electromyography comes: polyneuropathy with axonal features

What does "axonal features" mean?

3

Axonal features means that there is evidence to suggest damage to the axon as opposed to the myelin sheath.

Essentially axonal damage leads to a reduction of amplitude with preservation of nerve conduction velocity whereas demyelination results in a reduction of conduction velocity.

  • Thanks a lot. What difference does axonal damage make in the symptoms that patient might experience? Is there chances of slow improvement of such neuropathy? – Asmani Jan 29 '18 at 14:48
