Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a neurological disorder -- a condition that targets your body’s nerves.
Anyone can get CIDP, but it’s most common in older adults, and more in men than women. As many as 40,000 people in the U.S. may have the condition, but it’s hard to know how many people have it. CIDP isn’t easy to diagnose.
