Title: Pregnancy as a Risk factor for Stroke

Category: Neurology

Posted: 1/26/2011 by Aisha Liferidge, MD (Updated: 7/21/2026)

The risk of ischemic stroke or intracerebral hemorrhage (ICH) during pregnancy and the first 6 weeks postpartum is 2.4 times greater than for non-pregnant women of similar age and race.
The risk of ischemic stroke during pregnancy is not increased during pregnancy, per se, but is increased 8.7 fold during the 6 weeks postpartum.
ICH showed a small relative risk (RR) of 2.5 during pregnancy, but increased dramatically to a RR of 28.3 in the 6 weeks post partum.
Take Home Point: Your suspicion for true stroke should heighten in pregnant and post-partum patients, particularly for ICH and ischemic stroke during the the first 6 weeks after delivery.
