Can CIDP be misdiagnosed?

CIDP is sometimes misdiagnosed as other, less treatable conditions

CIDP shares similar symptoms with other diseases that impact the nervous system. Understanding your symptoms can help your doctor identify your condition and lead to a correct diagnosis.1

CIDP vs MS (Multiple Sclerosis)

While CIDP shares some symptoms in common with MS, certain symptoms such as problems with concentration, vision, speech, and the bladder are much more suggestive of MS.2

CIDP vs ALS (Amyotrophic Lateral Sclerosis)

Although some CIDP symptoms may appear similar to those of ALS, ALS does not cause numbness or tingling. Also, ALS commonly causes symptoms such as muscle twitching, weight loss, and muscle wasting as well as problems speaking, breathing, and swallowing.3

CIDP vs GBS (Guillain-Barré Syndrome)

GBS symptoms quickly develop over days to weeks, and then slowly get better again. CIDP symptoms progress gradually over 2 to 6 months or more.4
