In previous studies, pregnancy has been associated with less headache, but the influence of parity on this association is largely unknown. ⋯ Headache, both migraine and nonmigrainous, was less prevalent in nulliparous pregnant women compared with all nonpregnant women, and to nulliparous nonpregnant women. Headache was less prevalent in the third trimester of pregnancy, but not in the first and second trimesters, compared with nonpregnant women. Also in nonpregnant women, headache was less prevalent in nulliparous than in primi- and multiparous women.

Migraine is associated with vascular risk factors and white matter abnormalities (WMA). Cerebral hypoperfusion is known to be one mechanism underlying WMA and a few studies have shown that an incomplete circle of Willis (CW) may predispose to cerebral hypoperfusion. This study assessed the relationship between the morphologic characteristics of the CW and migraine. ⋯ Despite some methodological limitations, our results showed that incomplete posterior CW was associated with migraine.
