Frequent or chronic migraine negatively impacts personal, social and professional life.

INTRODUCTION Migraine affects 16% of the population and is a leading cause of disability. We aimed to describe the treatment status and impact of migraine in a selected cohort of patients with ≥ 4 migraine days per month. METHODS The study was conducted as a large, cross-sectional, multi-country online survey of adults (≥ 18 years) with migraine. Data presented here stem from 306 Danish respondents. Pre-specified quotas were applied so that 90% of respondents had used preventive migraine treatment and 80% had one or more treatment failures. RESULTS The median number of headache days per months was 11.3 (8-17.8) and 89 (29%) of patients met the criteria for chronic migraine. Most patients (n = 213; 70%) had taken preventive treatment (PT) for their migraines and among these 170 (80%) had experienced at least one treatment failure. Ninety-four (44.1%) patients reported being dissatisfied or mostly dissatisfied with their PTs. A negative impact of migraine on either private, social or professional life was reported by 303 (99.0%) patients; and among these, 195 (64.4%) reported an impact in all three domains. CONCLUSIONS Frequent or chronic migraine is associated with a considerable negative impact on personal, social and professional life. Treatment failure is frequent in this patient group, highlighting the need for continuous research and awareness of new treatment possibilities. FUNDING Novartis Pharmaceutical Corporation.
