Among the clinical episodes in which MOG-IgG appeared simultaneously with NMDAR-IgG, the clinical manifestations remained similar to the symptom spectrums associated with anti-NMDAR encephalitis, i.e., psychiatric symptoms (33/47, 70.21%), seizures (22/47, 46.81%), speech disorders (20/47, 42.55%), consciousness disorders (12/47, 25.53%), autonomic dysfunction (11/47, 23.40%), and movement disorders (11/47, 23.40%). This evidence concerns the gene MOG and movement disorder.
