Summary

This study looks at how often sleep disorders—like poor sleep quality, sleep apnea, and restless legs syndrome—occur in people with fibromyalgia. Researchers will use questionnaires to screen patients in specialized pain clinics across France. They will also ask doctors how they currently detect and manage sleep issues in these patients. The goal is to better understand the link between sleep and fibromyalgia symptoms, which could lead to improved care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Diagnostic orientation questionnaires for sleep disorder screening
What this could lead to: If successful, this could lead to better detection and management of sleep problems in fibromyalgia, potentially improving patients' quality of life.
What could go wrong: This is an observational study, so it won't test a treatment. It may only reveal how common sleep issues are, not whether fixing them helps fibromyalgia symptoms.
