The use of ID migraine™ questionnaire in patients with multiple sclerosis

Primary headaches are underdiagnosed and undertreated in patients with multiple sclerosis (MS). The aim of our study was to investigate the possibility of using the ID migraine™ (ID-M) questionnaire to make a first-line diagnosis of migraine in subjects affected by MS. We consecutively recruited 144 patients regularly attending the MS Centre of S. Andrea Hospital in Rome. Results from ID-M were matched with diagnoses of a blind neurologist. According to the ICHD-II criteria, 77 (53.5%) patients were diagnosed as suffering from migraine. ID-M showed high sensitivity (91%) and specificity (94%) in identifying patients with migraine. ID-M was also able to discriminate patients affected by headache following interferon beta therapy, having only the 10% out of these patients a positive ID-M. The use of the ID-M as a screening test is warranted not only in the epidemiological research, but also to ensure a better clinical management of patients with MS.
