Hemorrhagic Stroke (Bleeds)

A stroke occurs when the body stops supplying blood to the brain. Ischemic stroke is the most common type of stroke, and it develops due to a blockage in the arteries around the brain. In this article, we explain the causes of ischemic stroke, how to recognize when one is occurring, and ways to prevent and treat it. An ischemic stroke occurs due to atherosclerosis , which causes fatty deposits and a buildup of cholesterol plaque in the blood vessels.

A blood clot may stick to a plaque buildup while passing through the blood vessels, which also creates a blockage. The neck contains carotid arteries, which are blood vessels that supply blood to the brain. If plaque blocks a carotid artery carotid artery disease , a stroke might occur. Atherosclerosis is largely symptomless. Therefore, many people do not know they have atherosclerosis until they have a stroke or experience the other effects of blocked arteries near different organs, such as a heart attack.

People who have had a previous transient ischemic attack TIA are also at risk of ischemic stroke. Symptoms of a TIA are the same as those of an ischemic stroke, but they usually last less than 5 minutes and do not cause permanent damage.

About one-third of all people who have a TIA will experience a more severe stroke within 1 year. An interruption of blood supply to the brain causes all ischemic strokes. However, ischemic strokes can start in different areas of the body and may occur due to various types of blockage:. Learn about other types of stroke here. Strokes can be life-threatening, so it is important to seek medical care immediately if symptoms appear. This stands for:. Another person can check for this symptom by asking the person to smile or stick out their tongue.

If their smile is uneven, or their tongue moves to one side of the mouth instead of the middle, this could be a warning sign for ischemic stroke. The brain relies upon a constant supply of oxygen-rich blood, so a blockage that lasts for just a few minutes can begin to damage and destroy brain cells.

A person who is experiencing an ischemic stroke requires emergency treatment, which may include the following:. Medication: A member of the emergency team will inject tissue plasminogen activator tPA , which is a clot busting medication, through a vein in the arm.

Doctors must administer this medication within 4 hours from the beginning of stroke symptoms to have the desired effect. The chances of a positive outcome improve depending on how soon a person receives a shot of tPA.

Surgery to remove the clot: After a shot of tPA, a person experiencing an ischemic stroke may undergo a mechanical thrombectomy. This involves removing the clot with a catheter, and doctors must carry out this procedure within 6 hours of symptoms starting. Even people with risk factors or a history of stroke can take steps to improve cardiovascular health and reduce the risk of ischemic stroke. If a stroke is happening to a friend or family member, people should not drive them to a hospital.

Instead, they should call an ambulance, so that paramedics can provide medical care as quickly as possible. An ambulance can also take the person to the hospital that can provide the best stroke care, which is not always the closest facility.
