Neuropsychological assessment in migraine patients: a descriptive review on cognitive implications.

Migraine is considered a disabling disorder with highly prevalence in population. Recent studies report that migraine patients have a cognitive decline associated to structural brain alterations. We search on PubMed and Web of Science databases and screening references of included studies and review articles for additional citations. From 519 studies identified, only 16 met the inclusion criteria. All studies were conducted on 1479 migraineurs (190 non-migraine headache and 11,978 controls subject) and examined the association between migraine and cognitive impairment. The results are discordant. Indeed, while cognitive deficits during the attack of migraine are now recognized, only few studies confirmed the presence of cognitive impairment in migraine patients. Given the prevalence of migraine in the population (especially among women), and the early age of the population, an association between migraine and cognitive impairment could have substantial public health implications. Future studies should determine if specific migraine characteristics, for example, attack frequency, may impact the association between migraine and cognitive decline.
