Reply To: GBS and CIPD
That’s generally how they are distinguished. GBS reaches its maximum progression in eight weeks or less, typically in about four weeks. The most common form of GBS is AIDP, or Acute IDP. Chronic IDP can vary widely in presentation, sometimes developing slowly over years and sometimes relatively quickly. My case of CIDP reached maximum in eight to ten weeks, and was initially diagnosed as GBS. I am still more similar to a GBS case than to many CIDP cases, as I have not had any indications of relapse. There is a lot of variation in the presentation of these disorders, although severe cases of GBS tend to cause respiratory impairment more often than CIDP.
Treatment is similar except steroids are considered ineffective for GBS.
Ultimately, they are just names for a category of disorders which exhibit a lot of variation.
