A stroke occurs when the blood supply to part of your brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die. A stroke is a medical emergency. Prompt treatment is crucial. Early action can minimize brain damage and potential complications. The good news is that strokes can be treated and prevented, and many fewer Americans die of stroke now than in the av. Watch for these signs and symptoms if you think you or someone else may be having a stroke.
Pay attention to when the signs and symptoms begin. The length of time they have been present can affect your treatment options:. Seek immediate medical attention if you notice any signs or symptoms of a stroke, even if they seem to fluctuate or disappear. Think “FAST” acc do the following:. Call or your local emergency number right away. Don’t wait to see if symptoms stop. Uemiplegia longer a stroke goes untreated, the greater the potential for brain damage and disability.
If you’re with someone you suspect is having a stroke, watch the person carefully hemillegia waiting for emergency assistance. A stroke may be caused by a blocked artery ischemic stroke or the leaking or bursting of a blood vessel hemorrhagic stroke. Some people may experience only a hhemiplegia disruption of blood flow to the brain transient ischemic attack, or TIA that doesn’t cause permanent damage. Ischemic stroke occurs when a blood clot blocks or plugs an artery leading to the brain.
A blood clot often forms in arteries damaged by the buildup of plaques atherosclerosis. It can occur in the carotid artery aavc the neck as well as other arteries. About 80 percent of strokes are ischemic strokes.
Ischemic strokes occur when the arteries to your brain become narrowed avd blocked, causing severely reduced blood flow ischemia. The most common ischemic strokes include:. Hemorrhagic stroke occurs when a blood vessel in your brain leaks or ruptures. Brain hemorrhages can result from many conditions that affect your blood vessels. A less common cause of hemorrhage is the rupture of an abnormal tangle of thin-walled blood vessels arteriovenous malformation.

Types of hemorrhagic stroke include:. In an intracerebral hemorrhage, a blood vessel in the brain bursts and spills into the surrounding brain tissue, damaging brain cells. Brain cells beyond the leak are deprived of blood and are also damaged.
High blood pressure, trauma, vascular malformations, use of blood-thinning medications and other conditions may cause an intracerebral hemorrhage. In a subarachnoid hemorrhage, an artery on or near the surface of your brain bursts and spills into the space between the surface of your brain and your skull. This bleeding is often bemiplegia by a sudden, severe headache. A subarachnoid hemorrhage is commonly caused by the bursting of a small sack-shaped or berry-shaped aneurysm.
After the hemorrhage, the blood vessels in your brain may widen and narrow erratically vasospasmcausing brain cell damage by further limiting blood flow. A transient ischemic attack TIA — sometimes known as a hemi;legia — is a temporary period of symptoms similar to those you’d have in a stroke.
A temporary decrease in blood supply to part of your brain causes TIAs, which may last as little as five minutes. Like an ischemic stroke, a TIA occurs when a clot or debris blocks blood flow to part of your nervous system — but there is no permanent tissue damage and no lasting symptoms. Seek emergency care even if your symptoms seem to clear up.
Stroke – Wikipedia
Having a TIA puts you at greater risk of having a full-blown stroke, causing permanent damage later. If you’ve had a TIA, it means there’s likely a partially blocked or narrowed artery leading to your brain or a clot source in the heart. It’s not possible to tell if you’re having a stroke or a TIA based only on your symptoms. Even when symptoms last for under an hour, there is still a risk of permanent tissue damage.
Many factors can increase your stroke risk. Some factors can also increase your chances of having a heart attack. Potentially treatable stroke risk factors include:. A stroke can sometimes cause temporary or permanent disabilities, depending on how long the brain lacks blood flow and which part was affected.
Pain, numbness or other strange sensations may occur in the parts of the body affected by stroke. For example, if a stroke causes you to lose feeling in your left arm, you may develop an uncomfortable tingling sensation in that arm. People also may be sensitive to temperature changes, especially extreme cold, after a stroke. This complication is known as central stroke pain or central pain syndrome.
This condition generally develops several weeks after a stroke, and it may improve over time. But because the pain is caused by a problem in your brain, rather than a physical injury, there are few treatments.
As with any brain injury, the success of treating these complications varies from person to person. Knowing your stroke risk factors, following your doctor’s recommendations and adopting a healthy lifestyle are the best steps you can take to prevent a stroke. If you’ve had a stroke or a transient ischemic attack TIAthese measures might help prevent another stroke.
The follow-up care you receive in the hospital and afterward also may play a role as well. Many stroke prevention strategies are the same as strategies to prevent heart disease. In general, healthy lifestyle recommendations include:.
Controlling high blood pressure hypertension. This is one of the most important things you can do to reduce your stroke risk. If you’ve had a stroke, lowering your blood pressure can help prevent a subsequent TIA or stroke.
Exercising, av stress, maintaining a healthy weight and limiting the amount of sodium and alcohol you eat and drink can all help to keep high blood pressure in check. In addition to recommending lifestyle changes, your doctor may prescribe medications to treat high blood pressure. If you’ve had an ischemic stroke or TIA, your doctor may recommend medications to help reduce your risk of having another stroke.
Platelets are cells in your blood that form clots. Anti-platelet drugs make these cells less sticky and less likely to clot.
The most commonly used anti-platelet medication is aspirin. Your doctor can help you determine the right dose of aspirin for you. Your doctor might hemplegia consider prescribing Aggrenox, a combination of low-dose aspirin and the anti-platelet drug dipyridamole to reduce the risk of blood clotting. If aspirin doesn’t prevent your TIA or stroke, or av you can’t take aspirin, your doctor may instead prescribe an anti-platelet drug such as clopidogrel Plavix.
These hemi;legia, which include heparin and warfarin Coumadin, Jantovenreduce blood clotting.
Heparin is fast acting and may be used over a short period of time in the hospital. Slower acting warfarin may be used over a longer term. Warfarin is a powerful blood-thinning drug, so you’ll need to take it exactly as directed and watch for side effects. Your doctor may prescribe these drugs if you have certain blood-clotting disorders, certain arterial abnormalities, an abnormal heart rhythm or other heart problems.
Other newer blood thinners may be used if your TIA or stroke was caused by an abnormal heart rhythm. Stroke care at Mayo Clinic. Mayo Clinic does not endorse companies or products.
