S88 Optimizing the use of electrophysiology in the diagnosis of CIDP

Abstract

Chronic inflammatory demyelinating polyneuropathy (CIDP) is the most common chronic inflammatory neuropathy. It is heterogeneous in its clinical presentation and electrophysiology has a vital role in achieving the diagnosis, to avoid patients missing out on treatment. The electrophysiology of CIDP consists of features of demyelination. Although commonly seemingly straightforward, the electrodiagnosis can be difficult due to inadequate use of existing criteria as well as of normative values and inconsistent interpretation of findings in relation to the clinical context. Several rarely used parameters may also be helpful in establishing the diagnosis. There are otherwise some differentials that electrophysiology can be helpful to suspect or identify. The role of electrophysiology remains a very important one in the diagnosis of this relatively frequent and highly treatable neuromuscular disease.
