Brief Summary
In the International Headache and Vertigo Registration Study, patients aged 4-99 years with headache (primary headache and secondary headache such as migraine and tension type headache), vertigo (vertigo diseases such as vestibular migraine) and chronic pain (fibromyalgia and other diseases) were collected. The biomarkers, imaging features, right-to-left shunt of the heart (lung), genetic characteristics, treatment, and outcome (in relation to other diseases) of headache-related diseases were studied, and long-term follow-up was planned.

Outcome Measures
Primary Outcomes (3)
Days of Migraine
The number of days of migraine is the number of days in which migraine occurs or is likely to be migraine (according to IHS ICHD-3 diagnostic criteria). A migraine day is a day when a headache lasts for more than 30 minutes, does not take painkillers, and meets the ICHD-3 migraine or most likely migraine criteria. Migraine day can also be defined as a headache day that is effective for the acute treatment of specific migraine drugs (triptan, ditan, gepant, ergotamine, etc.).
Medium term: within 6 months after initial diagnosis; long term: 60 years
Moderate / Severe Headache Days
Moderate / severe headache days are defined as a day in which moderate or severe pain persists for at least 4 hours, or headache lasts for one day after successful medication for acute headache. These definitions allow the use of relatively simple headache diaries. Subjects were required to indicate whether headache was present (yes / no), peak (mild / moderate / severe) severity and duration (\< 4h or 4h), type of acute drug intake (triptan ergot / other), and response to treatment should also be recorded.
Medium term: within 6 months after initial diagnosis; long term: 60 years
Migraine Attack
Migraine attack is defined as any consistent migraine attacks or the use of specific migraine drugs. If a migraine attack is interrupted by sleep, or temporarily relieved, and then relapses within 48 hours, it is considered an attack. In addition, migraine attacks that were successfully treated with drugs but relapsed within 48 hours and lasted for more than 48 hours were counted as one attack.
Medium term: within 6 months after initial diagnosis; long term: 60 years
Secondary Outcomes (26)
The Response Rate of at Least 50%, 75% and 100% Reduction in the Number of Days of Migraine Attacks
Medium term: within 6 months after initial diagnosis; long term: 60 years
Headache Intensity
Medium term: within 6 months after initial diagnosis; long term: 60 years
Cumulative Hours of Moderate / Severe Pain at 28 Days
Medium term: within 6 months after initial diagnosis; long term: 60 years
Days Without Symptoms
Medium term: within 6 months after initial diagnosis; long term: 60 years
Days Without Headache
Medium term: within 6 months after initial diagnosis; long term: 60 years
