Stroke An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes. A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. Bleeding may occur due to a ruptured brain aneurysm.

Heart Disease and Stroke A stroke, sometimes called a brain attack, occurs when blood flow to an area in the brain is cut off. The brain cells, deprived of the oxygen and glucose needed to survive, die. If a stroke is not caught early, permanent brain damage or death can result.

Stroke Ischemic stroke occurs when a blood vessel that supplies blood to the brain is blocked by a blood clot. This may happen in two ways: 1  A clot may form in an artery that is already very narrow. 2  This is called a thrombotic stroke.

Differences Between a Stroke and a TIA Causes of Stroke vs. TIA. The causes of an ischemic stroke and a TIA are the same. They include heart disease, blood clotting problems, blood vessel abnormalities such as the ones caused by hypertension, diabetes, high cholesterol and smoking.

Latest News A stroke is caused when there is an interruption to the flow of oxygen rich blood to the brain. Without oxygen, brain cells can become damaged and die. Sudden bleeding in the brain can also cause a stroke if it damages brain cells. A stroke can result in brain damage, long-term disability, or even death.

Stroke A thrombus itself (even if it does not completely block the blood vessel) can lead to an embolic stroke (see below) if the thrombus breaks off and travels in the bloodstream, at which point it is called an embolus. Two types of thrombosis can cause stroke: Large vessel disease involves the common and internal carotid arteries, the vertebral artery, and the Circle of Willis.

Real Mom: My Baby Had a Stroke Stroke is a disease that affects the arteries leading to and within the brain. It is the No. 5 cause of death and a leading cause of disability in the United States. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (or ruptures). When that happens , part of the brain cannot get the blood (and oxygen) it needs, so it and brain cells die. Check out some interesting statistics about stroke.

- 1 Thrombotic stroke. A thrombotic stroke occurs when a blood clot (thrombus) forms in one of the arteries that supply blood to your brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions.  Embolic stroke.

Types of Stroke Ischemic Stroke. An ischemic stroke occurs if an artery that supplies oxygen-rich blood to the brain becomes blocked. Blood clots often cause the blockages that lead to ischemic strokes. The two types of ischemic stroke are thrombotic (throm-BOT-ik) and embolic (em-BOL-ik). In a thrombotic stroke, a blood clot (thrombus) forms in an artery that supplies blood to the brain.

Stroke Overview A stroke is a brain injury that occurs because the brain's blood supply is interrupted. The brain's blood supply can be disrupted for different reasons. Doctors generally classify strokes into three categories, depending on the cause: Hemorrhagic stroke — Bleeding (hemorrhage) causes this type of stroke. Bleeding can occur within the brain or between the brain and the skull. When bleeding occurs, small blood vessels near the hemorrhage tighten in a spasm. As a result, some brain areas get too little blood flow.

Stroke: Symptoms Causes & Treatment What is a Stroke. A stroke is the rapidly developing loss of brain functions due to a disturbance in the blood vessels supplying blood to the brain. This can be due to ischemia (lack of blood supply) caused by thrombosis or embolism or due to a hemorrhage. A stroke occurs when the supply of blood to the brain is suddenly interrupted.

- A American Heart Association-Stroke Association answered. One way a stroke occurs is that blood vessels to the brain become narrowed or clogged with fatty deposits called plaque, cutting off blood flow to brain cells. A stroke caused by lack of blood reaching part of the brain is called an ischemic (is-KEM-ik) stroke.

Atrial Fibrillation  (AF) Stroke (Cerebrovascular Accident). A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells. PubMed Health Glossary.

Everything you need to know about stroke Hemorrhagic stroke are caused by arteries in the brain either leaking blood or bursting open. The leaked blood puts pressure on brain cells and damages them. Blood vessels can burst or spill blood in the middle of the brain or near the surface of the brain, sending blood into the space between the brain and the skull.

- When this happens, the brain does not get enough oxygen or nutrients which causes brain cells to die. Strokes occur due to problems with the blood supply to the brain; either the blood supply is blocked or a blood vessel within the brain ruptures. There are three main kinds of stroke; ischemic, hemorrhagic and TIA.

Stroke A stroke occurs when a blood vessel to the brain or within the brain bursts or becomes blocked and no blood can flow to brain tissue. When blood flow stops, brain tissue begins to die. Time lost is brain lost! Clot-busting drugs, if given within 3 hours can open some blocked arteries.

Stroke An embolic stroke (a type of ischemic stroke) or TIA also can occur if a blood clot or piece of plaque breaks away from the wall of an artery. The clot or plaque can travel through the bloodstream and get stuck in one of the brain’s arteries. This stops blood flow through the artery and damages brain cells. Heart conditions and blood disorders also can cause blood clots that can lead to a stroke or TIA. For example, atrial fibrillation (A-tre-al fi-bri-LA-shun), or AF, is a common cause of embolic stroke.
