A Longitudinal Follow-up Study of the Patients With Medication-overuse Headache or Migraine That Completed Baseline MRI
This is a phone interview research study for patients with migraine or medication-overuse headache (MOH) who have completed baseline MRI scans. Participants will be interviewed by phone at 3, 12, 24 months after the baseline MRI scans. The purpose of this study is to potentially identify the baseline brain functional or structural signatures (functional connectivity, regional homogeneity, amplitude of low frequency fluctuation, and so such) that are predictive of the short- and long- term outcomes as well as treatment response of migraine and MOH patients.
• Participants who are diagnosed with migraine or MOH at baseline visit, signed the consent form, and completed MRI scans.
• Participants who are willing to take the phone interview during follow-up.
