This is a large research registry study in China that invites people with headaches, dizziness (vertigo), or chronic pain conditions like fibromyalgia to participate. Researchers will collect your medical history, blood samples, imaging scans, and genetic information to understand what causes these conditions, how they are related to each other, and which treatments work best. The study will follow participants for a long time to see how their conditions change and respond to treatment.
Headaches and dizziness affect millions of people, but doctors don't yet fully understand what causes them or why different treatments work for different people. By gathering information and samples from thousands of patients in one place, researchers hope to discover genetic and biological clues that could lead to better, personalized treatments.

If you join, you'll be asked to provide detailed information about your medical history and symptoms, possibly including blood or other biological samples for genetic testing, and imaging scans if medically appropriate. You may need to keep a headache or symptom diary. The study involves long-term follow-up, meaning researchers will check in with you over time to see how you're doing and how treatments are working. All your information will be stored securely and handled according to research privacy rules.
