Commonly used treatments are divided into so-called first-line (steroids, intravenous immunoglobulins, plasma exchanges) and second-line (rituximab, cyclophosphamide, tocilizumab, others), and may be used in association or sequentially. There is no standard practice, and initial treatment protocol may consist in first-line alone, first-line with rituximab, or first-line with dual immunosuppression (rituximab and cyclophosphamide). Absence of clear response to initial treatment in the first 4 to 6 weeks may indicate undertreatment and is generally followed by treatment escalation, mostly to dual immunosuppression. However, as the frequency of non-responders to initial treatment is unknown, it is still unclear whether dual immunosuppression should be offered to all patients from inception.",[81,82,83,84,85,86],"NMDAR Autoimmune Encephalitis","LGI1 Antibody Associated Encephalitis","CASPR2-Antibody","IgLON5","GAD65","GFAP",[88,89],"Paraneoplastic neurological disorder","autoimmune encephalitis","2025-08-13",{"date":92,"type":93},"2025-08-20","ACTUAL",{"date":95,"type":93},"2024-09-01",{"date":97,"type":77},"2027-03-01",{"name":5,"class":6},1]
