Early Functional Outcomes for Pediatric Patients Diagnosed with Anti-N-Methyl-D-Aspartate Receptor Encephalitis during Inpatient Rehabilitation

Abstract

Objective: The aims of the current study were to characterize the demographic and clinical presentation of pediatric patients diagnosed with anti-N-methyl-D-aspartate receptor encephalitis who require inpatient rehabilitation, to examine early functional outcomes, and to investigate predictors of early recovery.

Design: A retrospective chart review was conducted for 27 pediatric patients diagnosed with anti-N-methyl-D-aspartate receptor encephalitis who received intensive inpatient neurorehabilitation.

Results: On average, patients were 10.6 yrs of age (range, 2-18 yrs) at the time of symptom onset. Average time to treatment from symptom onset was 27.2 days (range, 5-91 days). Patients displayed significant improvements between admission and discharge Functional Independence Measure for Children (WeeFIM) Developmental Functional Quotient (DFQ) scores across patients (P < 0.01). Mean Functional Independence Measure for Children Total Developmental Functional Quotient score at admission was 28.6 (range, 15.0-62.6) and at discharge was 54.3 (range, 14.2-91.9). Younger age at onset, seizures, and number of treatments received were associated with worse functional outcomes at discharge. Time to initiate treatment was not found to be associated with early functional outcomes.

Conclusion: Pediatric patients diagnosed with anti-N-methyl-D-aspartate receptor encephalitis displayed significant functional gains during inpatient rehabilitation, despite persistent functional deficits at discharge, suggesting the need for ongoing monitoring and intervention.
