Researchers are conducting a large observational study called the China HeadAche Disorders Registry CHAIRS to better understand primary headaches and medication-overuse headaches MOH in patients aged 12 years and older. The study aims to collect detailed information including biomarkers, brain imaging, cognitive and genetic data, as well as social, demographic, medical, and treatment-related data. Long-term follow-up is planned to observe outcomes related to headache disorders over many years. Participants include those with various types of primary headaches such as migraine, tension-type headache, new daily persistent headache, and MOH. The study includes behavioral follow-up visits at multiple time points monthly for the first 18 months, then at 24 months, and annually thereafter. Some participants are observed during routine clinical use of treatments like Yangxue Qingnao Granules, Erenumab, and Eptinezumab, with treatment decisions made by their physicians and outcomes tracked over 12 weeks or longer. Throughout the study, participants undergo periodic assessments including MRI scans, cognitive tests like the Montreal Cognitive Assessment MoCA and Mini-Mental State Exam MMSE, and questionnaires evaluating headache impact, anxiety, depression, quality of life, sleep quality, and fatigue. Data on headache frequency, severity, medication use, and biological samples are collected. Follow-up can extend up to 10 years, allowing researchers to monitor long-term changes and outcomes related to headache disorders and treatments.
