This blood may cause nearby arteries to spasm, and that reduces blood flow to the brain and causes a stroke. When compared to ischemic strokes, hemorrhagic strokes tend to have an increased risk death in the acute phase , but for those patients that don’t die, their overall prognosis for return-to-baseline is somewhat better than ischemic events. It can cause permanent brain damage. Afterwards, as her hair grew out, she didn't have hair loss anymore, but she had been put on Lisonapril(sp) and when she had that changed because of other side effects , her hair started falling out just like before the stroke.

Besides killing the brain cells where the bleeding occurs, bleeding inside the skull can quickly raise the pressure on the brain to dangerous levels. High blood pressure is a common cause of hemorrhagic stroke. Subarachnoid hemorrhage can confidently be ruled out using specific criteria. Causes which may increase the risk of aneurysm rupture or AVM rupture include high blood pressure, physical exertion and emotional stress. Subarachnoid hemorrhage (SAH) is a frightening and potentially life-threatening disorder in which blood ruptures from an artery in the brain and leaks into the cerebrospinal fluid (CSF). 1, 2 Immediate aneurysm repair is particularly crucial because rebleeding occurs in 26% to 73% of patients within days or weeks after the initial rupture if the aneurysm is untreated.
