Migraine affects around 20% of Australians.3 It usually first occurs in childhood or early adulthood but is most common around the ages of 35–45 years, with women more likely to be affected than men.4
While it’s not clear why some people have migraine attacks and others don’t, several factors can increase the risk of getting migraine.1 These include family history,2 sex,1 and coexisting depression and anxiety.5 For women, hormonal factors can also influence the severity and frequency of migraine attacks over a lifetime.1,6
