Validation of the 2021 EAN/PNS diagnostic criteria for chronic inflammatory demyelinating polyneuropathy

Abstract
Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common immune-mediated neuropathy.1 Because of the lack of disease-specific diagnostic biomarkers, the diagnosis depends on combination of clinical, electrodiagnostic, and laboratory/neuroimaging findings, as well as exclusion criteria; and in clinical practice, misdiagnosis is not uncommon.
