Evaluation of the clinical assessment scale for autoimmune encephalitis (CASE) in a retrospective cohort and a systematic review.

Despite limitations such as retrospective design and small sample size, our findings underscore the CASE score's utility in both clinical practice and research settings. The CASE score emerges as a valuable tool for monitoring AE patients, offering improved sensitivity over existing scales like the mRS. Further validation studies in diverse populations are warranted to establish its broader applicability and inform future therapeutic interventions.
