[Autoimmune Encephalitis].

Abstract

Autoimmune encephalitides form a heterogeneous group of neurological and psychiatric diseases. In antibody-mediated encephalitis, autoantibodies are pathogenic and directly cause the encephalitis. In antibody-associated encephalitis, which is paraneoplastic most of the time, autoantibodies serve as diagnostic biomarkers and are able to predict the underlying tumour.
