Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired immune-mediated inflammatory disorder of the peripheral nervous system. The disorder is sometimes called chronic relapsing polyneuropathy (CRP) or chronic inflammatory demyelinating polyradiculoneuropathy (because it involves the nerve roots).

I was unable to post the link, so know this was lifted from the internet.

This is an autoimmune disease and treated with Immune Globulin for those who reach the diagnostic threshold. Many neurologists do not like IVIG as it has some severe side effects; but with my extensive experience with the drug I have seen many successes.

The main thing is to find a neurologist who has patients on IVIG already. You can call local Specialty Pharmacies and find the IVIG service provider, then ask them who they get orders from. That will help you find your doctor.
