title: Recent infection as a risk factor for intracerebral and subarachnoid hemorrhages.
abstract: Previous infection has been shown to be a risk factor for acute cerebral ischemia. We tested the hypothesis that recent infection is also a risk factor for intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). We performed a case-control study with 56 consecutive patients with ICH, 44 consecutive patients with SAH, and 56 and 44 neurological control patients, respectively. Infection within 4 weeks was associated with SAH independently of hypertension and smoking (p = 0.049). There was no significant association between infection and ICH. Recent infection, primarily upper respiratory tract infection, may be a risk factor for SAH by contributing to the formation and rupture of aneurysms.
