Migraine is one of the most disabling types of headache. It affects 4-6% of men and 13-18% of women; more than 80% of them are under 30 years. Many theories to explain mechanism of migraine are present; role of serum magnesium is one of them. This Cross-sectional analytical study was designed to see serum magnesium level status of migraine patients in Bangladesh and to find out any relation. The study was carried out in Outpatient Department of Neurology of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2017 to September 2018. Seventy (70) patients between 18-60 years of both sexes with headache fulfilling the criteria for migraine were enrolled as migraine group. Patients with headache who did not fulfill the criteria of migraine enrolled as non migraine group. Patients were included in both groups after exclusion of structural lesions, magnesium containing drug intake, pregnancy, menstruation, alcoholism, renal or GIT problems. Serum magnesium levels were studied in both groups and compared with each other. All related factors such as age, sex, family history of migraine, occupation were assessed. Fifty one (51) of 70 patients (72.85%) was female and 19(27.15%) were male in migraine group. Thirty eight (54.28%) of cases were between 18 and 30 years old. Thirty nine (55.71%) of migraine patients had history of similar headache in their family. Severe headache in 51.43% of migraine patients and 30% had more than three attacks per month. Mean serum magnesium level was 1.70 mg/dl in migraine group and 1.85 mg/dl in non migraine group (p=0.001). Serum magnesium level was also lower in severe migraine headache in comparison to mild to moderate headache (p=0.01). No significant difference was found in serum magnesium level compared according to age, sex, frequency of attack and presence or absence of aura. The study concludes that serum magnesium in migraine patients was significantly lower than non migraine group. It was also lower in migraine patient having severe headache in comparison with mild to moderate headache, though in both conditions they were within normal range.
