Migraine is an underrecognized, undertreated, and debilitating neurological condition affecting over 4.9 million Australians (Deloitte Access Economics, 2018) and recognised as the 6th most disabling disorder globally (Vos et al., 2017). Cognitive dysfunction has been reported as a significant impairment among migraine sufferers. While previous systematic reviews have examined the association between cognitive impairment and migraine, there is still much inconsistency regarding what cognitive domains are specifically impaired in migraineurs, how cognition varies within the migraine cycle and according to the characteristics of migraine (such as the presence of aura), and whether these findings generalize from clinical settings to migraineurs in the general population. The aim of this study is to conduct a meta-analysis to establish a clear profile of cognitive function in migraine by identifying the specific cognitive domains in which migraine patients demonstrate impairments as well as how these impairments vary according to the stage in the migraine cycle and characteristics of migraine experienced (such as presence of aura).
