Who is studied

Participants will be recruited from several headache centers around China including Tongji Hospital. The study population includes patients aged 6-70 years diagnosed with headache according to ICHD-3 (2018) criteria. Eligible participants must be mentally competent to provide detailed headache history and demonstrate willingness to comply with follow-up assessments. Patients with complex headache etiology (≥3 distinct causal factors), severe systemic diseases, limited life expectancy (\<10 years), or significant cognitive/psychiatric impairments affecting study participation will be excluded. A total of 1,500 participants meeting these criteria will be enrolled and followed for 5 years.
