In response to the controversial use of the concept of"autoimmune epilepsy",the International League Against Epilepsy has proposed conceptual definitions for 2 main diagnostic entities:acute symptomatic seizures secondary to autoimmune encephalitis(ASSAE)and autoimmune encephalitis-associated epilepsy(AEAE),which differ greatly in terms of major pathogenic antibodies,pathological changes,treatment options,and prognosis.In this review,a comprehensive interpretation of these 2 new concepts in terms of definition,epidemiology,aetiology,clinical manifestations,diagnosis and treatment is fully discussed,with the aim of addressing clinical issues in the treatment of ASSAE and AEAE,deepening neurologists'understanding of autoimmune etiology of epilepsy.
