MOG and viral encephalitis: Compared to typical anti-NDMAR encephalitis, we found patients with positive MOG-Ab had milder conditions, such as lower incidence of movement disorder (p = 0.003), seizures (p = 0.047), and lower PICU admission rate (p = 0.027), as well as better response to first-line immunotherapy (p = 0.036) (Table 1).
