Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators wish to test a diagnostic risk score for autoimmune encephalitis in case of encephalitis, previously validated by two American teams, in a retrospective analysis, according to the clinical and paraclinical data available in our database of the Reference Centre for Autoimmune Encephalitis and Paraneoplastic Neurological Syndromes of Professor Honnorat for patients with NMDAr, anti LGi1, anti CASPR2, anti GABAbr and anti GAD antibodies.
