Performance of the clinical assessment scale for autoimmune encephalitis in a pediatric autoimmune encephalitis cohort.

Background: The Clinical Assessment Scale for Autoimmune Encephalitis (CASE), a new scale used for rating the severity of autoimmune encephalitis (AE), has demonstrated good validity and reliability in adults with AE, but there is a shortage of data on its performance in children with AE. This study aimed to assess the reliability and validity of the CASE in a cohort of children with AE.

Methods: Forty-seven pediatric inpatients with AE who visited Guizhou Provincial People's Hospital between January 1, 2017, and October 31, 2021, were enrolled in the study.
