The clinical features, ancillary test results, and details of long-term outcomes were evaluated.Results: Among the 117 patients with anti-LGI1 encephalitis, 69.2% (81/117) were male and 30.8% (36/117) were female. The median age of all patients at the onset of the disease was 57 years (interquartile range [IQR], 52– 67). The median time from symptom onset to diagnosis was 8.7 weeks (IQR, 4.2– 25). The main clinical features identified were seizures, cognitive impairment, and mental and behavioral abnormalities. Of the 117 patients, 109 were treated with immunotherapy. Symptoms including memory, mental ability, and behavior improved in all 109 patients after 3– 5 days of treatment. The median time of follow-up for the treated patients was 33 months (IQR, 17– 42). Of the treated patients, 16.2% (19/117) experienced a relapse, with a median delay of 5 months (IQR, 2.1– 17) between onset and the first relapse. There were no mortalities over the follow-up period.Conclusion: The long-term outcome of patients with anti-LGI1 encephalitis was mostly favorable, although some patients continued to experience cognitive dysfunction. Early recognition is important for prompt initiation of immunotherapy that can improve clinical symptoms of anti-LGI1 encephalitis.Keywords: anti-LGI1 encephalitis, autoimmune epilepsy, follow-up, immunotherapy, relapse |
