Ischemic stroke meaning

A stroke is a medical emergency that happens when the blood flow to your brain is interrupted. Without blood, your brain cells start to die. This can cause serious symptoms, lasting disability, and even death. There’s more than one kind of stroke. Keep reading to learn about the three main types of strokes, their symptoms, and treatments. There are three main types of stroke: transient ischemic attack, ischemic stroke, and hemorrhagic stroke. It’s estimated that Transient ischemic attack Doctors also call a Ischemic stroke An ischemic stroke occurs when a blood clot keeps blood from flowing to your brain. The blood clot is often due to An ischemic stroke can be embolic, meaning the blood clot travels from another part of your body to your brain. An estimated A thrombotic stroke is an ischemic stroke caused by a clot forming in a blood vessel in your brain. Unlike a TIA, the blood clot that causes an ischemic stroke won’t go away without treatment. Hemorrhagic stroke A There are three main types of hemorrhagic strokes: The first is an The different stroke types cause similar symptoms because each affects blood flow in your brain. The only way to determine what type of stroke you may be having is to seek medical attention. A doctor will order imaging tests to view your brain. The • Face: When you smile, does one side of your face droop? • Arms: When you raise both arms, does one arm drift down? • Speech: Is your speech slurred? Are you having trouble talking? • Time: If you ...

A transient ischemic attack, or TIA, is a temporary blockage of blood flow to the brain. The clot usually dissolves on its own or gets dislodged, and the symptoms usually last less than five minutes. While a TIA doesn’t cause permanent damage, it’s a “warning stroke” signaling a possible full-blown stroke ahead. When you first notice symptoms, get help immediately, even if symptoms go away. Stroke rates double every 10 years after age 55. If you’ve previously had a stroke, pay careful attention for signs of a TIA because that could signal a second stroke in your future. Common warning signals include sudden onset of: • Weakness, numbness or paralysis on one side of your body • Slurred speech or difficulty understanding others • Blindness in one or both eyes • Dizziness • Severe headache with no apparent cause Major risk factors for a TIA or stroke include: Diagnosis and Treatment TIAs’ temporary symptoms, which can last from only a few minutes up to 24 hours, make diagnosis challenging. Stroke symptoms that disappear in under an hour need emergency assessment to help prevent a full-blown stroke. Get help immediately if you think you could be having a TIA. Ideally your comprehensive evaluation should be done within 24 hours of when symptoms began. Here is what you can expect: • Assessment for symptoms and medical history • Imaging of the blood vessels in the head and neck • Other testing such as head CT, angiography and MRI Once TIA is diagnosed, a follow-up visit with a ne...

From head to toe, your When you have a TIA, the flow of blood to part of your TIAs are short and won't cause lasting damage, but it's still important to treat them like an emergency and get care right away. What Causes a TIA? TIAs typically happen because a That's why you get symptoms like muscle weakness or slurred speech. It would be like having a clogged fuel line in your car. Your engine can't run if it's not getting gas. Clots form when you have a buildup of a fatty, waxy substance called plaque in your arteries. They can take shape anywhere in your body and float along until they get stuck somewhere. If that "somewhere" happens to be an artery that goes to your You can also get a TIA if so much plaque builds up in an artery that it severely limits blood flow to the brain, just like a clot. How Is a TIA Different From a Stroke? TIAs are very similar to ischemic strokes, which are also caused by The main difference is that a TIA only lasts a few minutes. The clot then gets pushed along, like a temporary clog in a pipe, or chemicals in your body quickly break it down. Normal blood flow returns to your brain before any lasting problems set in. Symptoms can last for up to 24 hours, but they're usually gone in an hour. Strokes, on the other hand, don't go away so quickly. That means some part of your brain goes without oxygen, and the longer that lasts, the more damage happens. While a TIA comes on, goes away, and leaves no symptoms, a Who's Most Likely to Have a TIA?

What is an Ischemic Stroke? An ischemic stroke occurs when a vessel supplying blood to the brain is obstructed. It accounts for about 87% of all strokes. The main cause of ischemic stroke is atherosclerosis, or fatty deposits (plaque) that line the vessel walls. Fatty deposits can cause two types of obstruction: • Cerebral thrombosis is a thrombus (blood clot) that develops at the site of fatty plaque within a blood vessel that supplies blood to the brain. • Cerebral embolism is a blood clot that forms in the heart or large arteries of the upper chest or neck, or at another location in the circulatory system. Part of the blood clot breaks loose, enters the bloodstream and travels through the brain’s blood vessels until it reaches vessels too small to let it pass. A main cause of embolism is an irregular heartbeat called atrial fibrillation. It can cause clots to form in the heart, dislodge and travel to the brain. Medication Treatment with Alteplase IV r-tPA Tissue plasminogen activator, r-tPA, (known as alteplase) is approved by the Food and Drug Administration to treat ischemic stroke. Doctors administer Alteplase IV r-tPA through an IV in the arm, dissolving the clot and improving blood flow to the part of the brain that’s deprived. Many people don’t arrive at the hospital in time to receive the medication, which can save lives and reduce long-term effects of stroke. So it’s important to identify stroke and seek treatment immediately. Mechanical Treatment to Remove the ...

A stroke is your brain’s equivalent of a heart attack, happening when there’s an issue with blood flow to part of your brain. This can happen when blood vessels are blocked or because of bleeding in your brain. Strokes are a life-threatening emergency, and immediate medical attention is critical to prevent permanent damage or death. A stroke is a medical emergency. Learn what to do if you or a loved one is having a stroke. What is a stroke? A stroke is a life-threatening condition that happens when part of your brain doesn’t have enough blood flow. This most commonly happens because of a blocked artery or bleeding in your brain. Without a steady supply of blood, the brain cells in that area start to die from a lack of oxygen. IMPORTANT: A stroke is a life-threatening emergency condition where every second counts. If you or someone with you has symptoms of a stroke, IMMEDIATELY call 911 (or your local emergency services number). The quicker stroke is treated, the more likely you’ll recover without disability. To recognize the warning signs of a stroke, remember to think BE FAST: • B. Be watchful for a sudden loss of balance. • E. Look out for sudden loss of vision in one or both eyes. Are they experiencing double vision? • F. Ask the person to smile. Look for a droop on one or both sides of their face, which is a sign of muscle weakness or paralysis. • A. A person having a stroke often has muscle weakness on one side. Ask them to raise their arms. If they have one-sided wea...
