“…The co-occurrence of migraine and mood disorders has been well documented in non-pregnant populations (Breslau et al, 1994; Breslau et al, 2003; Fuller-Thomson et al, 2013; Gelaye et al, 2013; Jette et al, 2008; Kalaydjian and Merikangas, 2008; McWilliams et al, 2004; Merikangas et al, 1990; Nguyen and Low, 2013; Patel et al, 2004; Saunders et al, 2014; Swartz et al, 2000; Zwart et al, 2003). Recent evidence suggests that migraine and mood disorders may be common among pregnant women (Cripe et al, 2010; Williams et al, 2010). In a study of 2,293 pregnant women, 55.1% of migraineurs reported moderate to severe depressive symptoms during pregnancy compared to 36.7% of pregnant non-migraineurs (Cripe et al, 2010).…”
