What this trial studies
This observational study aims to establish a national pregnancy registry for women with multiple sclerosis (MS) in France. It will follow patients with various forms of MS, including neuromyelitis optica spectrum disorders, throughout their pregnancy and for one year postpartum, as well as tracking their children until the age of six. The study seeks to gather data on the effects of pregnancy on MS, the use of disease-modifying drugs, breastfeeding, and locoregional analgesia. By analyzing these interactions, the study aims to provide valuable insights for neurologists and patients regarding the management of MS during pregnancy.
Why it matters
Potential benefit: If successful, this study could enhance understanding of how pregnancy affects multiple sclerosis and improve care for pregnant women with the condition.
How similar studies have gone: Previous studies have indicated the importance of understanding the relationship between pregnancy and multiple sclerosis, but this specific registry approach is novel.
