Stroke, also referred to as CVA or cerebrovascular accident, is a disease that affects the arteries leading to and within the brain. Stroke occurs when a blood vessel that carries blood and oxygen is either blocked by a clot, bursts, or ruptures (Dennis & Sen, 2015). When this happens, oxygenated blood fails to nourish tissues in the brain. Symptoms of a stroke vary and depend on the area of the brain affected. The most common symptom is weakness or paralysis of one side of the body with partial or complete loss of voluntary movement or sensation in a leg, arm or both (Dennis & Sen, 2015). There can also be speech problems, thought and/or coordination difficulty, and weak face muscles causing drooling, numbness, or tingling (Dennis & Sen, 2015). Symptoms that improve within 24 hours, or within minutes, with no evidence of a stroke are categorized as a mini stroke – or transient ischemic attack (TIA), which is caused by a temporary blood clot (Dennis & Sen, 2015). Those that have experienced a mini-stroke are at risk for a following stroke compared to those that …show more content…
Ischemic stroke occurs when there is something blocking the path of blood to the brain, while hemorrhagic stroke refers to a weakened blood vessel rupturing. Ischemic strokes are 87% more common and are like heart attacks because they are caused by oxygen being reduced or cut off completely from the heart (Dennis & Sen, 2015).
Per the American Stroke Association, 80% of strokes can be prevented (Dennis & Sen, 2015). Modifiable risk factors for stroke include: increased blood pressure, high cholesterol, not exercising, obesity, heart disease, and periodontal disease (Rudick, Wilson & Gurenlian, 2015). Race also plays a factor when it comes to an individual and their risk for stroke. African Americans are more likely to die from stroke due to their increased risk for high blood pressure, diabetes, and obesity (Rudick et al.
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,

Strokes are the most common cause of disability and leading cause of death in the United States. Estimates of the number of stroke survivors in the United States exceed 3 million, and nearly 150,000 Americans died from stroke in 1995. The frequency with which strokes occur and the devastating effects they can have on survivors and their families make provision of general information about prevention and management an essential element of public health education. Previous researchers have found that between 14% and 40% of adults cannot name a single risk factor associated with stroke. This is reason for concern among the medical community.
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).
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.
The animals that stroke primarily affects are humans. This is likely caused by risk factors that humans attain, such as cigarette smoking, high blood pressure, diabetes, high blood cholesterol, a poor diet, stroke occurring in ancestors, and physical activity/obesity. Stroke has is also starting to become recognized in cats, dogs, and rabbits. According to the World Health Organization, 15 million people suffer from a stroke worldwide every year. Of the people diagnosed, 5 million die and 5 million are permanently disabled. In the United States, 795,000 suffer from stroke annually. 85 percent of the diagnosed strokes are ischemic and 15 percent of them are hemorrhagic As for the humans diagnosed, three fourths of the people that suffer from a stroke are elderly (over the age of 65). This is caused by raising cholesterol levels and the narrowing of arteries as someone ages. Ethnicity, as well as age can also affect a person’s risk to fall victim to a stroke. Africans have a much higher risk of death from a stroke than Caucasians do. This is partly because blacks have greater risks of high blood pressure, diabetes, and obesity. Research suggests Africans may carry a gene that makes them more salt sensitive, inevitably increasing the risk of high blood pressure. Fortunately, research is still being done to prevent stroke. Rats and mice are primary animal subjects for studying this deadly

A cerebrovascular accident is known as a stroke. A Stroke is a major illness that affects many people within minutes. It happen when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients. This is an emergency that can’t wait too long to get treatment. The brain needs a consistent supply of blood, which carries the oxygen and nutrient it needs to function. Every artery in the brain works hard to supplies blood to the brain. A stroke occurs when one of these arteries are either blocked or burst. As a result, part of the brain does not get the blood it needs, so it starts to die. However, the more quickly you get treatment, the better the prognosis. At the point when a stroke goes untreated for a really long time, there can be permanent brain damage.
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...
A stroke includes the deterioration of brain cells as the brain cells die during a stroke which can cause brain damage and disability (association, 2014). There are two types of strokes Ischemic and Haemorrhagic stroke. The Ischemic stroke occurs when an artery in the brain becomes clotted due to a build-up of plaque or fatty deposits on the artery walls. This is the most common stroke as 87% of strokes are Ischemic in the USA. A Haemorrhagic stroke is when a blood vessel in the brain bursts cause 13% of all strokes and 30% of all stroke deaths (association, 2014).
