NewswiseStoke is the third leading cause of death in the United States and the number one cause of disability, with more than 3,000,000 people currently living with physical and mental impairment from brain damage caused by stroke. On average, someone in the United States suffers a stroke every 53 seconds and every 3.3 minutes someone dies of one.
Related QuestionsWhich type of stroke - ischemic or hemorrhagic - is more common?
NewswiseApproximately 84 percent of strokes are ischemic and 16 percent are hemorrhagic. Although hemorrhagic strokes are less common, they result in a higher morbidity rate (about 50 percent) than ischemic strokes (about 20 percent).
Related QuestionsWhat is a stroke?
NewswiseStroke is an abrupt interruption of constant blood flow to the brain that causes loss of neurological function. The interruption of blood flow can be caused by a blockage, leading to the more common ischemic stroke, or by bleeding in the brain, leading to the more deadly hemorrhagic stroke. In any event, proper blood flow and oxygen must be restored to the brain as soon as possible. Without oxygen and important nutrients, the affected brain cells are either damaged or die within a few minutes.
Related QuestionsStrokeA stroke is sometimes called a "brain attack." A stroke can injure the brain like a heart attack can injure the heart. A stroke occurs when part of the brain doesn't get the blood it needs. Ischemic stroke (most common type) -- This type of stroke happens when blood is blocked from getting to the brain. This often happens because the artery is clogged with fatty deposits (atherosclerosis) or a blood clot.Related Questions
Stroke Frequently Asked QuestionsStroke, or brain attack, is damage to part of the brain caused by sudden block of its blood supply by a clot. Less commonly it occurs when a clot travels through the blood vessel from one part of the body to the brain (embolism) or when there is rupture of blood vessel and bleeding into the brain (haemorrhage). When blood flows to the brain stops, brain cells in that part of the brain may die. Stroke may damage parts of the brain that control how you move, feel, speak, think and behave.Related Questions
Which Are the Common Types of Stroke?
FAQ's Epidemiology of StrokeThe usual mode of expression of cerebrovascular diseases is the stroke, denned as a sudden, nonconvulsive and focal neurological deficit. Strokes are generally classified into two groups. The most frequent type of stroke results from cerebral infarction (ischemic stroke) whereas in 15-20% of cases, stroke is due to intracranial parenchymatous hemorrhage. Approximately 30% of cerebral infarctions result from atherothrombosis in the aortic arch and in extracranial arteries [Bogousslavsky ct al.
Related QuestionsIS HEAT STROKE A COMMON PROBLEM?
FAQsNo! With traditional saunas, which may reach over twice the body's average temperature (up to 200? F!), the heat can disturb the brain's temperature-regulating region, the hypothalamic region. When the head is unprotected, heat stroke can occur. However, far infrared saunas operate effectively at much lower temperatures, so heat stroke is not likely to occur.

Related QuestionsWhat is a stroke and what are the warning signs of stroke?
FAQ (Frequently Asked Questions) - Texas Heart Institute Hea...A stroke is an injury to the brain that may also severely affect the body. A stroke happens when blood supply to part of the brain is cut off or when there is bleeding into or around the brain. This can happen if a blood clot blocks an artery in the brain or neck or if a weakened artery bursts in the brain. Risk factors for stroke include high blood pressure, smoking, heart disease, diabetes, and a high red blood cell count. The risk of stroke also increases with age.
Related QuestionsIs there anything that I can do to prevent a stroke?
NewswiseModifiable risk factors for stroke are easily recognizable and treatable and, if managed properly, can reduce a patient's risk of stroke more than ten-fold. Following are modifications you can make to your lifestyle to reduce your risk for stroke: Control your blood pressure. High blood pressure is the leading cause of both ischemic and hemorrhagic stroke and should be treated and kept to a low level of 140/90. Eat a healthy diet and exercise regularly.
Related QuestionsWhat is an ischemic stroke?
NewswiseAn ischemic stroke is caused by atherosclerosis, or the build up of cholesterol-containing fatty deposits called plaque. As the plaque roughens the inside of an artery and the vessel begins to narrow, the flow of oxygen and nutrients to the brain becomes disrupted. A thrombolic stroke is the most common form of ischemic stroke. It occurs when a clot, or thrombus, develops in arteries that have been narrowed by fatty buildup that has formed on the inner layers of the artery walls.
Related QuestionsWhat is a hemorrhagic stroke?
NewswiseA hemorrhagic stroke occurs when a blood vessel in the brain leaks or ruptures and blood spills into the surrounding brain tissue, thereby preventing needed oxygen from reaching the brain. The most common form of hemorrhagic stroke, known as a subarachnoid hemorrhage (SAH), occurs when an aneurysm that has weakened over time balloons and suddenly bursts, forcing blood into the area surrounding the brain (subarachnoid space).

Related QuestionsWhat is heat stroke?
Frequently Asked QuestionsHeat stroke is the most serious heat-related illness. It occurs when the body becomes unable to control its temperature: the body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Body temperature may rise to 106?F or higher within 10 to 15 minutes. Heat stroke can cause death or permanent disability if emergency treatment is not provided.
Related QuestionsWhat causes a stroke?
Quality Health | Strokeischemic stroke develops when a blood clot blocks a blood vessel in the brain. The clot may form in the blood vessel or travel from somewhere else in the blood system. About 8 out of 10 strokes are ischemic (say “is-KEE-mik”) strokes. They are the most common type of stroke in older adults. A hemorrhagic stroke develops when an artery in the brain leaks or bursts. This causes bleeding inside the brain or near the surface of the brain.
Related QuestionsHow is a stroke diagnosed?
Quality Health | StrokeSeeing a doctor right away is very important. If a stroke is diagnosed within the first 3 hours, doctors may be able to use medicines that can lead to a better recovery. The first thing the doctor needs to find out is what kind of stroke it is—ischemic or hemorrhagic. This is important because the medicine given to treat a stroke caused by a blood clot could be deadly if used for a stroke caused by bleeding in the brain.
Related QuestionsCan you prevent a stroke?

GWTG-Stroke focuses on quick diagnosis and treatment of stroke patients through Primary Stroke Centers. It also involves care team protocols once patients are admitted to ensure that they are treated and discharged appropriately.
Related QuestionsWhat are the effects of stroke?
StrokeIt depends on the type of stroke, the area of the brain where the stroke occurs, and the extent of brain injury. A mild stroke can cause little or no brain damage. A major stroke can cause severe brain damage and even death. A stroke can occur in different parts of the brain. The brain is divided into four main parts: the right hemisphere (or half), the left hemisphere (or half), the cerebellum, and the brain stem.
Related QuestionsWho is at risk for stroke?
StrokeIt is a myth that stroke occurs only in older adults. A person of any age can have a stroke. But, stroke risk does increase with age. For every 10 years after the age of 55, the risk of stroke doubles, and two-thirds of all strokes occur in people over 65 years old. Stroke also seems to run in some families. Stroke risk doubles for a woman if someone in her immediate family (mom, dad, sister, or brother) has had a stroke.
Related QuestionsHow is stroke treated?
StrokeStrokes caused by blood clots can be treated with clot-busting drugs such as TPA, or tissue plasminogen activator. TPA must be given within three hours of the start of a stroke to work, and tests must be done first. This is why it is so important for a person having a stroke to get to a hospital fast. Other medicines are used to treat and to prevent stroke.
