Clinical Report: The Role of Symptom Clusters in Mediating Anxiety and Depression

Overview

This study investigates how symptom clusters mediate the impact of anxiety and depression on quality of life (QOL) in patients with neuromyelitis optica spectrum disorder (NMOSD). Findings indicate that distinct symptom clusters significantly influence the relationship between psychological distress and QOL.

Background

Neuromyelitis optica spectrum disorder (NMOSD) is a severe inflammatory disease affecting the central nervous system, leading to significant neurological disability and psychiatric comorbidities. Anxiety and depression are prevalent in NMOSD patients and are associated with lower QOL. Understanding the pathways through which these psychological factors affect QOL is crucial for improving patient management.

Data Highlights

Patients with NMOSD had a QOL score of 97.76 ± 8.24. Significant negative correlations were found between anxiety/depression and QOL, with symptom clusters mediating these relationships.

Key Findings

• 140 NMOSD patients were recruited for the study.
• Anxiety and depression were found to negatively correlate with QOL.
• Complete mediation of anxiety through somatosensory and motor symptom clusters was observed.
• Depression showed complete mediation through somatosensory, motor, visual-memory, and bladder-rectal symptom clusters.
• Sleep-related symptom clusters did not demonstrate significant mediating effects.

Clinical Implications

The findings highlight the importance of assessing both psychological and physical symptoms in NMOSD patients to better understand their impact on QOL. Clinicians should consider these symptom clusters when developing treatment plans.

Conclusion

This study underscores the mediating role of symptom clusters in the relationship between anxiety/depression and QOL in NMOSD patients, suggesting a need for integrated management approaches.
