Burden of migraine in patients attending Belgian headache specialists: real-world evidence from the BECOME study

IntroductionMigraine is a primary headache disorder, which imposes a major burden on the sufferers. The BECOME study (Burden of migrainE in specialist headache Centers treating patients with prOphylactic treatMent failurE) attempted to characterize and assess the prevalence, burden and healthcare resource utilization of migraine patients presenting in specialized headache centers in Europe and Israel. In this paper, we will describe the patient characteristics of the Belgian headache centers.MethodsThe BECOME study was a prospective, non-interventional, cross-sectional study consisting of two parts. In the first part of the study, data were collected from subjects with a diagnosis of migraine. Subsequently, patients with >= 4 monthly migraine days (MMD) and >= 1 prior preventive treatment failure (PPTF) filled out validated questionnaires to assess the burden of disease.ResultsIn part 1 of the Belgian study population (N = 806), 45% of patients reported >= 8 MMD and 25% had failed >= 4 preventive treatments. In part 2 (N = 90), more than 90% of patients reported having severe impact of headache on daily life and having severe migraine-related disability. The impact was the highest for patients with >= 15 MMD, however, even within the patient population with < 8 MMD, the burden was significant. Almost 40% of the study population suffered from anxiety.ConclusionsThese findings in the Belgian sample of the BECOME study demonstrate the substantial burden and unmet need for the management of difficult-to-treat migraine.
