Clinical Trial Summary

The investigators conduct this study to clarify the clinical features and to evaluate the prevalence of anti-nodal/paranodal antibodies of patients with combined central and peripheral demyelination (CCPD) .


Description:

The investigators will review the clinical manifestation, laboratory test results, electrophysiological examination and neuroimaging findings of patients with CCPD. And we will detect antibodies to aquaporin 4(AQP4), myelin oligodendrocyte glycoprotein (MOG), neurofascin-155 (Nfasc155), neurofascin-186 (Nfasc186), and myelin-associated glycoprotein (MAG) in patients with CCPD.
