Your participation in the study will be either a single-day assessment or it will last 2 years. This depends on which preventive migraine medication you are prescribed as part of your routine care.
You will be asked to complete short questionnaires lasting 1-5 minutes each. If you qualify for the stage of the study that lasts 2 years, you will be asked to keep an electronic subject headache diary that you will be encouraged to fill out every time you experience a headache. You will fill out additional questionnaires due every 3 months or less often.
