Hemorrhagic Stroke Risk In Women Addressed By AHA/ASA For The First Time (1)
Recent research has shown that migraineurs and especially those who experience aura are at an increased risk of a stroke (brain hemorrhage) or a heart attack during a migraine episode. My post of June 20th, 2013 speaks of this research (on high risk of stroke among the migraining population): http://bit.ly/1iON349
A stroke may be either ischemic or hemorrhagic in nature. A hemorrhagic stroke is the rupturing of an artery in the brain which results in bleeding in the tissues surrounding the rupture and killing the brain cells there which are devoid of blood, oxygen and nutrition. An ischemic stroke occurs when there is an obstruction like cholesterol or clot in the arteries in the brain. These account for almost 90% of all strokes and are less likely to result in fatality if given immediate attention. However, migraineurs are more susceptible to the deadlier hemorrhagic strokes. (2)

Given that women are more susceptible to migraines with aura, the higher risk of getting a stroke is inherent yet there have been no guidelines to date to address stroke issues in women. Finally a guideline has been issued by The American Heart Association/American Stroke Association for health professionals to prevent strokes in women. Here are a few of the important recommendation highlights you should know:
1. FOR MIGRAINEURS
“Women are four times more likely to have migraines than men, and they often coincide with hormone swings. Migraines alone don’t raise the risk of stroke, but ones with aura do. Using oral contraceptives and smoking raise this risk even more, so the guidelines urge stopping smoking.” (3)
2. FOR ELDERLY WOMEN
Women over 75 years of age should be screened for atrial fibrillation as it is an increased stroke risk factor.
3. FOR WOMEN WITH HYPERTENSION/ HIGH BLOOD PRESSURE
Low dose aspirin or calcium supplement therapy is recommended to cut of stroke risk
4. WOMEN WITH PRE-ECLAMPSIA
Preeclampsia is a condition where a pregnant woman experiences both high blood pressure and a significant increase in protein in her urine. Women with preeclampsia are twice as likely to get a stroke and four times as likely to suffer from high blood pressure later in life. In addition, they are to be treated for weight and cholesterol issues as well as smoking.
5. PREGNANT WOMEN:
Such women who are pregnant and suffer from high blood pressure (>=160/110 mmHg) should be given medication for high blood pressure. Those who are expectant are to be treated for readings in the range of 150-159 mmHg/100-109 mmHg. (4)
