Autoimmune encephalitis (AE) is a potentially life-threatening inflammation of the central nervous system (CNS) and constitutes 20%-30% of encephalitis cases in adults AE often leads to subacute, severe, and debilitating encephalitis necessitating long-term management in a neurologic intensive care unit (ICU). This study aims to explore the predictive factors for poor clinical outcomes by analyzing the clinical characteristics and prognosis of adult patients with critical AE requiring ICU admission. Prospective observational single center study in neurologic ICU, the second Xiangya hospital, Central South University. All patients admitted to the ICU for probable or confirmed AE (2022 Chinese guidelines for diagnosis and treatment of AE) will be included. Factors associated with a poor prognosis will be identified by multivariate analysis using a logistic regression.
Diagnosed as either ''definite'' or ''probable'' AE based on Chinese guidelines for diagnosis and treatment of AE (version 2022)

Modified Rankin Scale
The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. It has become the most widely used clinic. mRS is scored on a scale of 0 to 6. The higher the score, the worse the prognosis
Mortality
Rate of death at 12 months
Rate of complications
Septic shock, hyponatremia
