ClinConnect Summary

Migraine is a common disease with lifetime prevalence in women and men of 33% and 12% respectively. Chronic migraine affects 2% of the US population and is highly disabling. There are no FDA approved medications for the treatment of chronic migraine.

Although some patients benefit from a daily prophylactic medication, others continue to suffer from severe, frequent, debilitating headaches. Limited efficacy, poor compliance, side effects and drug-drug interactions may explain why more than 80% of migraineurs in the population are not prescribed daily prophylactic medications.
