Gender-Related Differences in Aneurysmal Subarachnoid Hemorrhage: A Hospital Based Study

The incidence of aneurysmal subarachnoid hemorrhage (aSAH) is 50% higher in women than in men [1,2]. Possible reasons for such a gender gap include repeated childbirths, hormonal factors, higher hemodynamic forces acting on the intracranial vessel wall, and a more severe impact of smoking on women [3 –6]. Repeated childbirths are associated with an increased risk of aSAH, possibly through pregnancy-induced hypertension and vascular tension during delivery, which weakens vessels and may lead to aneurysm formation [3].
