Stroke is the third cause of death in the United States. Stroke is the interruption of blood in the brain. According to the American heart association 730000 Americans are affected by stroke per year 160000 resulting in death. Also stoke is s the number one cause of disability of the United States. The main reason why strokes occurs is hypertension, smoking, heart disease and family history. However 90% of the strokes is because of fat accumulated in the carotid artery or when the blood clots becoming to stay in the carotid arteries. There are six types of strokes these are ischemic stroke, transient ischemic attack (TIA), embolic stroke, hemorrhagic stroke, thrombotic stroke, and lacunar infarction
Ischemic Stroke is the death of the brain tissue that occurs because of lack of blood supply and insufficient oxygen to the brain due to blockage of an artery. During 60 to 90 seconds the brain tissue could stop working and after approximately three hours it will suffer irreversible injury possibly leading to death of the tissue. Most of the time that the Ischemic Stroke occurs is when the blood is clot or fatty deposit due to atherosclerosis.is blocking the …show more content…
It happens when a weak vessel breaks and bleeds into the brain which results blood to accumulate and compresses the brain. To help prevent hemorrhagic stroke patient should do brain imaging so they can evaluate and identify complications such as intraventicular hemorrhage, brain edema, or hydrocephalus. The symptoms for the hemorrhagic stroke are the same as the Ischemic stroke but also depends in which side of the body happen. The treatment depends on the cause and severity of the bleeding. Also medications are use for the treatment such as Anticonvulsant which help prevent seizure recurrence, antihypertensive agents help reduce blood pressure and other risk factors of heart disease and osmotic diuretics that helps decrease intracranial pressure in the subarachnoid

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. To achieve this aim this report will firstly talk about the cerebrovascular system with its structure and functions. The main body of this report will look at causes, symptoms, diagnosis, treatments and prevention of stroke.
The human body is an amazing machine, we have cells, tissues, organs and organ system that come together to create the human race. Each system plays a key role in our bodies mechanism. Without each systems our bodies would not function properly, but what happens when one of these system fails? The Cardiovascular system components are blood, blood vessels and the heart. The hearts function is to pump blood to all the major organs and tissues (Circulatory). It’s also important to be aware of the derivation that our bodies may encounter, for example a stroke. In this passage I discuss different types of strokes, what are the signs and symptoms and after care for this disorder of the cardiovascular system.
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.
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,
Many underlying factors can contribute for someone to have a stroke; these including not limited to:artherosclerosis,(harding of the arteries) commonly from fat consummation, heart disease (generally) hypertension(high blood pressure), kidney disease, peripheral vascular disease, and diabetes mellitus. Cerebrovaslar accident is an abnormal condition of the blood vessels of the brain, characterized by occlusion , an embolus ,or hemorrhage, resulting of a lack of blood supply in the brain tissues (ischemia) normally perfused by the damage vessels. CVA (orstroke) is the most common disease of the nervous system and Is ranked as the third leading cause of death in the United Stated., with About 200,000 deaths annually. According to Foundation of Nursing by Barbara Christensen/Elaine Kockrow( second Edition) Strokes affect persons in all age
Stroke is the third leading cause of death and the brain injuries caused by stroke are a huge cause of disability in older adults. There are over 1.2 million stroke survivors in the UK and half of all stroke survivors have a disability following their stroke. A person’s age increases their risk of having a stroke. Most strokes occur between the ages of 65 and 75. There are three main types of strokes. 85% of strokes are ischaemic and occur when a blood clot forms in an artery leading to the brain, stopping the blood supply causing a neurological defect lasting more than 24 hours (Alexander et al., 2011). 15% of strokes are haemorrhagic and result from a weakened blood vessel that has ruptured and bleeds into the surrounding brain. It can be
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
Stroke is one amongst the foremost distressing experiences that can happen to anyone. A stroke is caused by an intermission of the blood offer to half of the brain. The term ‘stroke’ comes from the actual fact that it always happens with none warning, ‘striking’ the person from out of the blue. Worldwide, each year 2/1000 individuals have a stroke. Five out of six strokes happen in individuals over the age of sixty. It is hardly ever obvious why somebody ought to have suffered a stroke. Contrary to widespread belief, stress, and either future or following a sudden event, is not in itself a reason behind a stroke. The most common is obtaining older and alternative factors are high blood pressure (hypertension), smoking, being overweight, having too much sugar in blood (diabetes) and having abundant in excessive amount of cholesterol in blood. Strokes occur once the blood flow within the brain is hampered and brain tissue is broken. There are 2 major varieties of strokes: Ischemic and Trauma. The severity of injury to the brain tissue depends on several factors together with age, area of the brain affected, and alternative medical conditions. If the hand and arm doesn’t have medical aid in real time when stroke, it will reduce the power and muscle management, leading to a claw like look and loss of perform. Activities of the patient daily legal document will be significantly affected.
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).
CVAs occur when blood circulation to a brain area is blocked and brain tissue dies of ischemia, a reduction of blood supply that impairs the delivery of oxygen and nutrients. The most common cause of CVA is a blood clot that blocks a cerebral artery. A clot can originate outside the brain or form on the roughened interior wall of a brain artery narrowed by atherosclerosis. Less frequently, strokes are caused by bleeding, which compresses brain tissue. Not all strokes are "completed." Temporary episodes of reversible cerebral ischemia, called transient ischemic attacks (TIAs), a...
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...
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...
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
