Patient-Reported Outcome Measures in NMDA Receptor Encephalitis

Area of Science:

• Neuroimmunology
• Autoimmune Encephalitis
• Neuropsychiatry

Background:

• Long-term sequelae of N-methyl-D-aspartate receptor (NMDAR) encephalitis are not fully understood.
• The impact of persistent symptoms on patients' subjective quality of life requires further investigation.

Purpose of the Study:

• To evaluate postacute neuropsychiatric symptoms and subjective cognitive complaints in NMDAR encephalitis patients.
• To identify predictors of health-related quality of life (HRQoL) in this patient population.
• To assess disease coping mechanisms employed by survivors.

Main Methods:

• Cross-sectional observational study of 50 postacute NMDAR encephalitis patients.
• Utilized psychometric scales to assess neuropsychiatric symptoms (fatigue, sleep, anxiety, depression), HRQoL, independence, metamemory, and coping strategies.
• Multivariable regression analyses were performed to identify HRQoL predictors.

Main Results:

• Patients reported significantly higher anxiety, depressive symptoms, sleep disturbances, and fatigue compared to normative data.
• Lower self-rated memory ability correlated with increased use of compensatory strategies.
• Health-related quality of life (HRQoL) was predicted by affective symptoms, self-efficacy, and coping behaviors, not acute disease severity or physical disability.

Conclusions:

• Persistent neuropsychiatric and cognitive issues are major contributors to reduced quality of life in NMDAR encephalitis.
• Coping strategies play a crucial role in the neurorehabilitation and recovery of autoimmune encephalitis patients.
• Findings support a patient-centered approach to postacute care, focusing on psychological and cognitive well-being.
