Medium-term Effects of Treatments in Autoimmune Encephalitis

"The patients will be identified via the French Nationwide Multidisciplinary Team Meetings for Autoimmune encephalitis, which are conducted on a bi-monthly basis. All patients with newly diagnosed NMDAR, LGI1, CASPR2, IgLON5, GFAP or GAD65 encephalitis and treated for less than 8 weeks will be included. Treatment protocols at the initiation of therapy will be stratified into: 1) first-line only; 2) rituximab without cyclophosphamide; 3) rituximab combined with cyclophosphamide; 4) others.~The referral clinicians will be contacted by email and the data will be collected using standardized questionnaires, which will be sent at baseline (visit 1, V1) and 4 months after the initiation of therapy (visit 2, V2). The questionnaires will be structured into 7 sections:~* 1 Demographics~* 2 Symptoms~* 3 Cognitive screening tests (MMSE, MoCA, and/or others)~* 4 Level of dependence (ADL, I-ADL, mRS, CASE) and impact on social life~* 5 Diagnostic tests (brain MRI, brain PET, CSF, and EEG findings)"
