Figure 1 Electrodiagnostic findings in Morvan syndrome. Panel A shows unrecognized F-wave responses due to peripheral nerve hyperexcitability. Panel B presents T2 flair and enhanced scans of head MRI. In panel C, dynamic video electroencephalogram monitoring captures the patient’s abnormal nighttime behavior. Panel D demonstrates the detection of anti-Caspr2 autoantibodies in the serum (1: 30) but not in the cerebrospinal fluid, using cell-based assay.
