Migraine headache in Multiple Sclerosis. Is more frequent among MS patients?

Abstract

Objectives. Multiple sclerosis (MS) is a chronic disease of the central nervous system that is associated with inflammation, demyelination of neurons and gliosis. There are different reports about the association between migraine and MS. Taking note of headaches experienced by people with MS and providing appropriate treatment can help enhance their quality of life. We aimed to determine the frequency of migraine headache in MS patients. Materials and methods. This was a descriptive cross-sectional study, conducted in 2020 among 125 MS patients referred to neurology clinic of Poursina Hospital or registered in Guilan MS Registry System and 125 controls with minor head trauma in Rasht. After obtaining written consent, all the subjects were asked to fulfil a checklist about their demographics, MS and headache characteristics by phone call. Outcomes. In this study 96 RRMS, 19 PPMS and 10 SPMS patients participated among which frequency of mild, moderate and severe disability was 74.4%, 22.4% and 3.2%, respectively. The frequency of migraine in MS patients was significantly higher than the control group [28.8% (n=36) vs. 12.8% (n=16) p=0.002]. After adjusting the confounding factors a significant relationship was found between MS and migraine (OR: 2.76, p = 0.004). Conclusions. MS patients experience migraine headaches approximately twice the general population.
