Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to characterize sex hormone alterations and their potential clinical significance in NMOSD patients from Southern China through comprehensive hormonal profiling.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a prospective cohort study, aiming to explore the characteristics of sex hormone levels in patients with neuromyelitis optica spectrum disorder (NMOSD). It plans to include 2,000 patients with NMOSD and 2,000 healthy controls, and conduct a 3-year follow-up. By regularly collecting data such as serum sex hormone levels, imaging, neurological function scales, and various biomarkers, the differences between the two groups will be compared and analyzed to reveal the role of sex hormones in NMOSD and their association with disease activity.
