The leaked blood puts too much pressure on brain cells, which damages them.\r\n\r\nHigh blood pressure and aneurysms\u2014balloon-like bulges in an artery that can stretch and burst\u2014are examples of conditions that can cause a hemorrhagic stroke.\r\n\r\nThere are two types of hemorrhagic strokes:\r\n<ul>\r\n \t<li><strong>Intracerebral hemorrhage<\/strong> is the most common type of hemorrhagic stroke. It occurs when an artery in the brain bursts, flooding the surrounding tissue with blood.<\/li>\r\n \t<li><strong>Subarachnoid hemorrhage<\/strong> is a less common type of hemorrhagic stroke. It refers to bleeding in the area between the brain and the thin tissues that cover it.<\/li>\r\n<\/ul>\r\n<h3>Transient Ischemic Attack (TIA)<\/h3>\r\nA transient ischemic attack (TIA) is sometimes called a \"mini-stroke.\" It is different from the major types of stroke because blood flow to the brain is blocked for only a short time\u2014usually no more than 5 minutes.\r\n\r\nIt is important to know that:\r\n<ul>\r\n \t<li>A TIA is a warning sign of a future stroke.<\/li>\r\n \t<li>A TIA is a medical emergency, just like a major stroke.<\/li>\r\n \t<li>Strokes and TIAs require emergency care. <strong>Call 9-1-1<\/strong> right away if you feel signs of a stroke or see symptoms in someone around you.<\/li>\r\n \t<li>There is no way to know in the beginning whether symptoms are from a TIA or from a major type of stroke.<\/li>\r\n \t<li>Like ischemic strokes, blood clots often cause TIAs.<\/li>\r\n \t<li>More than a third of people who have a TIA end up having a major stroke within 1 year if they don\u2019t receive treatment, and 10%-15% will have a major stroke within 3 months of a TIA.<\/li>\r\n<\/ul>\r\nRecognizing and treating TIAs can reduce the risk of a major stroke.
