Clinical features and outcomes in children with seronegative autoimmune encephalitis.

Aim: To characterize the presenting features and outcomes in children with seronegative autoimmune encephalitis, and to evaluate whether scores at nadir for the Modified Rankin Scale (mRS) and Clinical Assessment Scale for Autoimmune Encephalitis (CASE) or its paediatric-specific modification (ped-CASE) are predictive of outcomes.

Method: This observational study included children younger than 18 years of age with seronegative autoimmune encephalitis. Demographics and clinical data were collected.
