Women, Mexican-Americans at higher risk of ruptured brai...(pAn SAH is different from the other type...),Health

Both types of bleeding stroke are somewhat more dangerous than ischemic or "blockage" strokes, which result from a clot or other blockage inside a brain blood vessel. Ischemic strokes account for more than 85 percent of U.S. strokes.

The signs of an SAH usually include a sudden, extremely severe headache, often compared to a "thunderclap" inside the head. Patients may also experience neck pain, nausea and vomiting, or may lose consciousness.

No matter what the signs, a stroke or suspected stroke of any kind is a life-threatening emergency and needs immediate medical attention, says Morgenstern. Although SAH carries daunting odds, it can be treated if a patient reaches a hospital where a neurosurgeon or interventional radiologist can close off the ruptured aneurysm and stop the bleeding.
