ABSTRACT=Background: Patients with anti-N-methyl-D-aspartate receptor encephalitis (NMDARE) usually achieve neurologically favorable outcomes in the post-acute-phase. Even when motor function recovers, many patients experience numerous non-motor sequelae and cannot resume their pre-NMDARE lives even years later. Additionally, the needs of patients with NMDARE may impose a severe caregiver burden. Unfortunately, few studies have comprehensively examined patients recovering from NMDARE. We investigated the long-term effects of NMDARE on patients' quality of life (QOL).
Methods: Data collected via structured self-reported questionnaires included clinical features, long-term outcomes, and QOL. These questionnaires were administered to adult members of the Japanese Anti-NMDARE Patients' Association. We used the NeuroQOL battery to assess QOL in physical, mental, and social domains. Raw NeuroQOL scores were converted to T-scores for comparison with controls.
Results: Twenty-two patients completed the questionnaire. The median interval between disease onset and questionnaire response was 78 months. Forty-six percent of patients reported persistent sequelae, with only 73% able to resume prior work/school activities. Although patients’ Global QOL was similar to controls, patients with NMDARE had significantly worse social QOL. Patients with worse social QOL had more-frequent sequelae than those with better social QOL. Furthermore, patients with persistent sequelae had significantly worse Global QOL than those without sequelae and controls.
Conclusions: Patients with NMDARE had worse social QOL than controls. Given the adverse effects of disease sequelae on QOL, treatment strategies that minimize sequelae during the acute-phase may improve patients' QOL, even years post-disease onset.
