13. The Migraine Connection

Holy headache, Batman! It turns out migraines can be a family affair, and those pesky pains target female 30-somethings like rubber ducks in a shooting gallery: The reality is, migraines can be hereditary and 38 million Americans suffer from them, with women in their 30s being three times more likely to experience these debilitating aches. Those with migraines are also four times more likely to suffer from depression and anxiety – a migraine-inducing combo. Fear not, though – the OHSU Headache Center is here to save the day with treatments that'll have you singing "na na na na na na na na, bye-bye pain!"
