Clinical and Magnetic Resonance Imaging Outcome Predictors in Pediatric <scp>Anti–N‐Methyl‐D‐Aspartate</scp> Receptor Encephalitis

Abstract

Children with NMDARE exhibit significant brain volume loss and failure of age-expected brain growth. Abnormal MRI findings, a clinical presentation with sensorimotor deficits, and a treatment delay > 4 weeks are associated with worse clinical outcome. These characteristics represent promising prognostic biomarkers in pediatric NMDARE. ANN NEUROL 2020 ANN NEUROL 2020;88:148-159.
