Changes in serum NMDAR antibodies (NMDARAb) and Immunoglobulin G (IgG) levels. The continuous test results for serum NMDARAb demonstrate a decrease in titer and subsequent stabilization following the administration of efgartigimod. The titer further decreases after re-administration of efgartigimod. Additionally, the serum IgG and the CSF NMDARAb indicate a sustained decrease in titer post-efgartigimod treatment
