CIDP Prevalence, Disease Burden, and Clinical Challenges
ByJeffrey Allen, MD ,Thomas H. Brannagan III, MD,Joshua Alpers, MD,Suraj Muley, MD, FAAN, FRCP, FACP Welcome back to another NeurologyLive Peer Exchange series. The panel opens with a discussion of CIDP prevalence, noting that estimates vary depending on the diagnostic criteria used. A strict case definition from a New South Wales population study places prevalence at approximately 1 per 100,000, while a more clinically based study from Olmsted County suggests a higher figure of around 1 in 10,000. One expert contextualizes this further, estimating that roughly 40,000–50,000 patients in the U.S. are affected, and that CIDP accounts for approximately 20% of patients presenting to peripheral neuropathy centers with initially unrecognized neuropathy. The panel characterizes CIDP as rare but not ultra-rare.
