In a study of women in Denmark with and without migraines who became pregnant, migraines were associated with an increased risk of pregnancy-associated hypertension disorders in the mother. Also, in newborns, maternal migraine was associated with an increased risk of a variety of adverse outcomes, including low birth weight, preterm birth, cesarean delivery, respiratory distress syndrome, and febrile seizures.
