multi-centrally recruit patients with newly onset or chronic epilepsy and hoping to find whether there exist an autoimmune cause. whether the patients receive immune therapy or not will depend on the type and titter of the autoimmune antibody as well as the severity of the symptom. At 3 and 6 months later, all patients will be followed-up, and the positive autoimmune antibody will be redetected. the clinical manifest, clinical data, medication and treatment outcome will be recorded and analyzed, to study the diagnostic value of autoimmune antibody detection in new and chronic epilepsy
multi-central and prospectively study the diagnostic value of autoimmune antibody detection in new and chronic epilepsy, and provide reference for clinical practice
