People often know of strokes or someone affected by a stroke, but not always what constitutes a stroke. A stroke occurs when blood flow to the brain is interrupted or reduced due to a blockage or rupture of a blood vessel or artery that supplies blood to the brain. The interruption of blood flow deprives the brain of necessary nutrients and oxygen supplies, killing surrounding cells in the brain.
There are three main types of strokes: ischemic stroke, hemorrhagic stroke, and transient ischemic stroke. Ischemic strokes occur due to an obstruction or clotting of a blood vessel or artery. There are two types of ischemic strokes: embolic and thrombotic strokes. An embolic stroke is when a blood clot or other substance forms in the body, travels through the blood stream, and eventually becomes lodged in a small blood vessel or artery supplying blood to the brain. A thrombotic stroke is when a blockage forms in one or more arteries to the brain. The second type of stroke, hemorrhagic stroke, is due to a rupture of a weakened blood vessel. There are two major ways in which blood vessels can weaken: aneurysm, a ballooning of a weak area in a blood vessel, and arteriovenous malformations (AVM), an abnormal connection of arteries to veins. A hemorrhagic stroke can either be an intraccerebral stroke, a bleed caused by a blood vessel within the brain, or a subarachnoid stroke, an aneurysm rupture in a large artery near the membrane surrounding the brain. Lastly, transient ischemic attacks are temporary traveling clots that cause “miniature” or “warning” strokes.
There are many causes of strokes and risk factors that can increase likelihood of stroke. Causes include conditions such as atherosclerosis, also known as plaque build...

Ischemic Stroke is caused due to a blood clot in an area of the brain, leading to loss of neural function if last for more than 24 hours. In the United States, ischemic stroke affects 2.7% of men and 2.5% of women of age range 18 years and older. In addition, it has reported that annually about 610,000 and 185,000 of new strokes and recurrent strokes cases occur in US1. Moreover, it has reported that patients who have suffered from a stroke have more chances of recurrent stroke, Myocardial infarction, and death from vascular causes2. One of the risk factor of ischemic stroke is formation of plaque in the blood vessels causing blood clot3. Several randomized trials have also reported that antiplatelet medications are efficient in preventing recurrences of stroke in patients who had an incident of ischemic stroke. Antiplatelet medications for preventing recurrences of stroke are aspirin, combination of aspirin and extended-release dipyridamole, and clopidogrel alone4. It ha...
Stroke occurs when the blood supply to the brain is blocked or condensed. Blood works to transport oxygen and other beneficial substances to the body’s cells and organs, as well as the brain. There are two main types of strokes that are known as Ischemic strokes and Hemorrhagic strokes. When the blood vessels that provides for the brain becomes congested, is it referred to as ischemic stroke, the most common stroke within adults. Blood clots, a cluster of blood that sticks together, are the cause of Ischemic strokes. Ischemic strokes also takes place when arteries become backed up with plague, leaving less blood to flow. Plague is cholesterol, calcium and fibrous and connective tissue that sticks to the walls of blood vessels. Ischemic strokes eternally damage the brain and cause a person's body to no longer function habitually.Some risk factors that may increase stroke are high cholesterol, diabetes, high blood pressure, and obesity. Some stroke factors are also due to old age or having a family that has a history of strokes. Men are more likely to have a stroke but the most st...
It goes without saying that everyone’s health is important and should be taken care carefully. Everyone has heard of strokes before but many people do not really know its meaning, types, and the number of individuals of that dies due to this issue. According to Centers for Disease Control and Prevention (2015), strokes kills an average of 130,000 people a year and it is one of the most common deaths that happen in the United States. An average of 800,000 of people die from cardiovascular disease and strokes and it is also a reason of long-term disability (Centers of Disease Control and Prevention, 2015). Strokes, which can also be called cerebrovascular accident or CVA happen when the blood supply to the brain is interrupted or the blood vessel going towards the brain burst. Then part of the brain dies or become seriously injured because the brain cells do not receive oxygen and they eventually die. People’s lifestyle may also impact seriously on their health and increase the possibility of having a stroke. Some of the risk that can severely increase the cause of stroke would be high blood pressure, heart disease, diabetes, cigarette smoking, as well as strokes that
A stroke can happen at any age but for patients who are 55 and older, their risk factor will increase due to age and physical activity. “While stroke is common among the elderly, a lot of people under 65 also have strokes”(“About Stroke” page 1). Also at risk are African Americans because of other health issues that can trigger a stroke, for example: high blood pressure, diabetes and obesity. Caucasians and Hispanics are also at. Not only does Ethnicity and age play a factor, but so does other health conditions. Patients who suffer from high blood pressure, diabetes, heart disease, obesity, alcohol and drug
The bleeding of the brain also causes increased pressure on the brain and it presses against the skull. Symptoms of a hemorrhagic stroke vary upon the amount of blood tissues affected and the location of the bleeding. A transient ischemic attack only lasts for a few hours of the day or a day and it doesn't cause permanent brain damage like an ischemic stroke would. (TIA) transient ischemic attack is not considered to be a stroke, it is referred to as a warning signal before having a stroke. Ask yourself how does a stroke change a person's everyday life drastically? People who suffer from strokes have to live with a mental or physical disability that causes them to be limited.
So, what is actually happening when a stroke occurs? A stroke occurs blood flow to the brain is either impeded or significantly reduced. When this happens, the brain cells are starved of the essential oxygen and nutrients they need and begin to die. There are three different kinds of strokes. They are ischemic, hemorrhagic,

The World Health Organisation (2013) explains that an Ischaemic stroke occurs as a result of a blood vessel becoming blocked by a clot, reducing the supply of oxygen to the brain and, therefore, damaging tissue. The rationale for selecting Mary for this discussion is; the author wishes to expand her evidenced based knowledge of stroke since it is the principal cause of disability and the third leading cause of mortality within the Scottish population (Scottish Intercollegiate Guidelines Network (SIGN), 2008) and, therefore, a national priority. In response to this priority, the Scottish Government (2009) produced their ‘Better Heart Disease and Stroke Care Action Plan’. Additionally, they have introduced a HEAT target to ensure 90% of stroke patients get transferred to a specialised stroke unit on the day of admission to hospital (Scottish Government, 2012).
“Time is brain” is the repeated catch phrase when addressing the treatment and management of stroke (Saver, 2006). Access to prompt and appropriate medical care during the first few hours of stroke onset is critical to patient survival and outcomes. Recent changes in the guidelines for acute stroke care released by the American Heart Association (AHA) and the American Stroke Association (ASA) have improved patient access to treatment. Stroke treatment now follows the model of myocardial infarction treatment. Hospitals are categorized into four levels based on stroke treatment capability. The most specialized treatment is available in comprehensive stroke centers followed by primary stroke centers, acute stroke-ready hospitals, and community hospitals. The use of telemedicine now enables even community hospitals, with limited specialized capabilities, to care for stroke patients. Telemedicine puts emergency hospital personnel in contact with neurologists providing expertise in the evaluation of a stroke patient and determination of their eligibility for treatment with thrombolytic medication (Jefferey, 2013).
It is caused by clot that blocks blood vessels from supplying blood to the brain through cerebrovascular events. If there is no blood in the brain, then there is no oxygen or nutrients because it is blood that supplies it to the brain. This can cause permanent brain damage which can cause inflammation. Fasting has there been known to be effective and efficient against stroke because it increases cognitive functioning and health of the brain. In addition, fasting has been known to increase neuro-protective proteins and reduction in inflammatory substance known as cytokines. This is critical reducing the chances of damaging the brain that can cause
Nowadays, stroke has become one of the major causes of death and lifelong disability in adults
1. What is the difference between a. and a. Introduction The main aim of this report is to present and analyse the disease called Cerebrovascular Accident, popularly known as stroke. This disease affects the cerebrovascular system, which is a part of the cardiovascular system.
I realized it was a stroke,” –Fred, a stroke survivor. Some of the most common symptoms indicating that a stroke is occurring include sudden numbness or loss of movement in the limbs on one side of your body or face, sudden vision changes, sudden trouble speaking, sudden confusion, a very intense headache, or sudden balance issues. Stroke is simply acquired when the blood supply to the brain is suspended, but to get to the roots of what causes it, a stroke is triggered by the slowly forming plaque buildup over time. The plaque is made up of calcium, fat, cholesterol, cellular waste, and fibrin, a material involved in blood clotting. The plaque existing in an artery can grow big enough to block the supply of blood to the brain, resulting in a stroke. A stroke can also be caused by high blood pressure breaking a blood vessel in the brain causing internal bleeding. Although there is no cure, as damage the brain is usually irreversible if not cared for quickly; there are different treatments available for both types of stroke. For an ischemic stroke, a tissue called plasminogen activator can be injected into an artery to break up
Stroke is a serious medical condition that affects people of all ages specifically older adults. People suffer from a stroke when there is decreased blood flow to the brain. Blood supply decreases due to a blockage or a rupture of a blood vessel which then leads to brain tissues dying. The two types of stroke are ischemic stroke and hemorrhagic stroke. An ischemic stroke is caused by a blood clot blocking the artery that brings oxygenated blood to the brain. On the other hand, a hemorrhagic stroke is when an artery in the brain leaks or ruptures (“About Stroke,” 2013). According to the Centers for Disease Control and Prevention (CDC), “Stroke is the fourth leading cause of death in the United States and is a major cause of adult disability” (“About Stroke,” 2013). Stroke causes a number of disabilities and also leads to decreased mobility in over half of the victims that are 65 and older. The CDC lists several risk factors of stroke such as heredity, age, gender and ethnicity as well as medical conditions such as high blood pressure, high cholesterol, diabetes and excessive weight gain that in...
The topic I will be covering in the paper is a condition called a stroke. I know many people know the brief information about a stroke but I am here to go into full detail of what a stroke really is, how a person can suffer a stroke, history, and treatments for stroke patients, also if you have suffered from or has a family member suffering from a stroke hopefully I can find a good support site to go to for information and help on the topic at hand. A stroke is when either a blood clot blocks the blood flow to the brain which is called a Ischemic stroke which makes ups about 85% of all strokes which would be a lot, or a blood vessel could burst in your brain causing a hemorrhage which starts to accumulate blood and compresses the brain tissue which can cause brain damage. There are 2 different types of strokes the first one is called a intracerebral hemorrhage stroke which is the most common of the two and is when an artery in the brain burst can compresses surrounding tissue in the brain. (CDC, 2010). The second form of a hemorrhage stroke is called subarachnoid hemorrhage which is bleeding in the area that is located between the brain and the thin tissue that covers it. (CDC, 2010). When it comes to races there is a difference in who is more at risk. African Americans and Native Americans are the most likely victims of a stroke in between them Hispanics and at the bottom are white people. The chance of and African American getting a stroke is twice that of a white person, not only are they at a much higher risk African Americans are also more likely to die after having the stroke than whites. Age of onset varies because anybody can have a stroke it is true that the older you get the higher your chances are of getting a stroke b...
