Migraine-related disability and co-morbid depression among migraineurs in Ethiopia: a cross-sectional study

Migraine headache is a neurologic disorder which mainly affects younger and productive segment of population. Migraine not only causes pain; but also affects quality of life in terms of low productivity and economic loss. The main aim of this study was to examine migraine-related disability, co-morbid depression, and relationship between the two.

A cross-sectional study was conducted among migraineurs who visited two neurology referral clinics. The study was conducted between June 1st 2016 to December 30^th2016. Migraine disability assessment score [MIDAS] and patient health questionnaire [PHQ-9] were used to assess disability and depression, respectively.

A total of 70 patients participated in the study. Fifty-three (74.3%) of our study participants were women. Fifty one (72.9%) study participants were between age group 20-40 years. Migraine without aura was the most common subtype (70%); migraine with aura accounted for the other 28.6%. The mean (± SD) headache frequency and intensity was 23.4 ± 14.9 days and 7.4 ± 1.2 respectively. Major depressive disorder was common in this group (41.4%). The mean MIDAS and PHQ-9 scores were 46.7 ± 30 and 9.2 ± 4.4 respectively. More than two-thirds (74.3%) of our participants had severe disability. We found a statistically significant correlation between migraine-related disability and co morbid depression among our participants(r = 0.318, p-value = 0.007).

The positive correlation observed between migraine-related disability and co-morbid depression warrant routine screening and treatment of disability and depression in migraineurs; In addition, the observed high degree of disability among our participants may indicate sub optimal treatment of these patients.
