"278 Ischemic Stroke Most strokes (85%) are ischemic strokes. If you have an ischemic stroke, the artery that supplies oxygen - rich blood to the brain becomes blocked. Blood clots often cause the blockages that lead to ischemic strokes. Hemorr hagic Stroke A hemorrhagic stroke occurs when an artery in the brain leaks blood or ruptures (breaks open). The leaked blood puts too much pressure on brain cells, which damages them. High blood pressure and aneurysms — balloon - like bulges in an artery that can stretch and burst — are examples of conditions that can cause a hemorrhagic stroke. There are two types of hemorrhagic strokes: • Intracerebral hemorrhage is the most common type of hemorrhagic stroke. It occurs when an artery in the brain bursts, flooding the surrounding tissue with blood. • Subarachnoid hemorrhage is a less common type of hemorrhagic stroke. It refers to bleeding in the area between the bra in and the thin tissues that cover it. Transient Ischemic Attack (TIA) A 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 — us ually no more than 5 minutes. It is important to know that: 25 A TIA is a warning sign of a future stroke. 26 A TIA is a medical emergency, just like a major stroke. 27 Strokes and TIAs require emergency care. Call 9 - 1 - 1 right away if you feel signs of a stroke or see symptoms in someone around you. 28 There is no way to know in the beginning whether symptoms are from a TIA or from a major type of stroke. 29 Like ischemic strokes, blood clots often cause TIAs. 30 More than a third of people who have a TIA end up having a maj or stroke within 1 year if they don’t receive treatment, and 10% - 15% will have a major stroke within 3 months of a TIA. A health care team can usually find the cause and take steps to prevent a major stroke. Recognizing and treating TIAs can reduce the ris k of a major stroke. Recognizing a Stroke – Think FAST! During a stroke, every minute counts! Fast treatment can lessen the brain damage that stroke can cause. By knowing the signs and symptoms of stroke, you can take quick action and perhaps save a life — maybe even your own. Signs of Stroke in Men and Women"
