Chronic Migraine: clinical trials and information

Migraine is a neurological condition with recurring headaches that are often throbbing and may come with nausea and sensitivity to light or sound. Chronic migraine usually refers to headache on 15 or more days a month for more than three months, with migraine features on at least eight of those days.

Diagnosis is usually based on the pattern of symptoms described in a history and a neurological examination. A headache diary is often used. Tests may be done to rule out other causes.

Registered studies cover medicines, medical devices (such as nerve stimulators), procedures (such as nerve blocks or injections), physical and movement therapies, psychological approaches (such as cognitive behavioural therapy), education programs and digital tools. Being studied in a trial does not mean a treatment works or is approved. The interventions listed on this page come directly from the registry records.

This page lists 2 registry records for this term with at least one site in Canada, recruiting studies first. Each trial page links to the official ClinicalTrials.gov record, which lists the study contacts. Recruiting status changes often, so check the registry, and talk to your doctor before joining a study.
