Migraine: Prevalence and Associated Disability Among Nigerian Undergraduates

Background: Studies on migraine in Nigeria are scanty while the disability associated with the disease hits not been determined. We aimed at determining the lifetime prevalence of migraine and its associated disability among the students of a Nigerian university. Method: Using a multi-stage sampling method, Undergraduates of Ambrose Alli University. Nigeria were screened with the International Headache Society (IHS) criteria. Those who satisfied the criteria for migraine were then assessed with the Migraine Disability Assessment questionnaire to ascertain the level of disability resulting from migraine in the three months preceding the study. Information was also obtained on the use of preventive and abortive medications. Results: Out of the 15 13 respondents screened, 145 satisfied the IHS criteria for the diagnosis of migraine giving all overall lifetime prevalence of 9.6% (females 10.3%, males 8.9%, p>0.05). Migraine associated disability wits little or none in 53.1% (males 55.2%. females 5 1.3%, p>0.05), mild in 10.3% (males 11.9%, females 9.0%, p>0.05), moderate in 20.7% (males 20.9%, females 20.5%. p>0.05) and severe in 15.9% (males 11.9%. females 19.2%. p>0.05). In spite of the fact that 53 (36.6%) of the migraineurs had moderate-severe disability, only 19/53 (35.8%) reported being oil preventive treatment while none had ever used it triptan. Conclusion: Prevalence of migraine among our respondents falls within the range reported from similar Studies among university Students Outside Africa. In spite of the high disability associated with the disease, use of effective preventive and abortive therapies is very poor.
