Documentation of peripheral nerve demyelination is an important part of the CIDP diagnostic process. We performed a retrospective analysis of patients referred with a diagnosis of CIDP who were found to have a different condition. Electrodiagnostic study data and interpretations performed at the time of the initial diagnosis were compared to those obtained during the re-evaluation. Thirty-nine of 86 patients were found to not have CIDP. Initial electrodiagnostic data quality was generally acceptable, but initial electrodiagnostic conclusions were confirmed in only 45% of misdiagnosed studies. Vulnerability to interpretive errors increases when amplitude-dependent slowing occurs with length-dependent axonal neuropathies or motor neuron disease, amplitude-independent slowing occurs in diabetic patients, fibular nerve to EDB muscle findings are the focal diagnostic abnormality, conduction block is absent, CV slowing is limited to compressible sites, and when accurate electrodiagnostic interpretations are dismissed in favor of equivocal clinical and CSF findings.
