About the AMPP Study
The American Migraine Prevalence and Prevention (AMPP) Study is the largest study of migraine sufferers ever conducted, analyzing symptoms and treatment patterns in a representative sample of 162,576 Americans age 12 and older.
- The study found that approximately 12 percent of Americans have migraines, and approximately 40 percent could benefit from preventive therapies.
- Of migraine sufferers in the study, only one in five currently use preventive therapy.
Almost 98 percent of migraine sufferers take medications for temporary headache relief, but a large majority report their lives are still significantly affected by the pain and debilitation associated with migraines.
- Nine out of 10 migraine sufferers report they can’t “function normally” during days in which a migraine strikes, and nearly three in 10 require bed rest.

- Nearly 50 percent of sufferers report their migraines prevented them from doing household chores.
- Approximately 30 percent of migraine sufferers did not participate in a family or social activity due to a migraine.

- The study found that more than half of migraine sufferers only take over-thecounter (non-prescription) medications or none at all.
