I would wonder about prions.

I wonder if a lot of folks with CIDP now, would have been diagnosed with MS 20 years ago. Plus, if you don't get a sural nerve biopsy....I don't think they can diagnose CIDP. Don't most folks with CIDP get that diagnosis off the sural nerve biopsy?

They don't want to do sural nerve biopsies anymore, unless really pushed for some compelling reason to do so. If you only have a skin nerve fiber density biopsy, such as I have, they don't diagnose CIDP...at least not to my knowlege. Please correct me if I am wrong, because CIDP responds to IVIG, and I no longer get IVIG, as my SNF was deemed not to be inflammatory.
