Stroke is a clinical syndrome produced by acute interruption of the normal blood flow to an area of the brain. This then causes the brain to lose important nutrients as well as oxygen which will prevent it to keep functioning up to par. This is a consequence from a thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. The outcome is persistent dysfunction related to the affected structures. There are many ways that strokes may occur, they can be cardiogenic or hemorrhagic. Stroke can happen at any age from the youth to the elderly. In most cases it occurs suddenly and could take from five to seven days to completely affect the person. If not treated or found on early onset, stroke can not only cause extreme harm but can also be fatal. Some people recover fully, while others only recover to some extent. Each year people in America die from a stroke or are seriously disabled. Although most cases are preventable, Stroke is still the 3rd leading cause of death in the United States.
Stroke has been implicated as the third leading cause of death1. It’s occurrence increases with age, with two-thirds of stroke victims being over 65 years old2. The elderly population is increasing, with 20% of the U.S. population expected to be over 65 years old by the year 20303. As future dentists, these are the people we will one day be treating in our practices. Therefore, it is important for us to be able to properly prevent, recognize, and manage the diseases of the elderly population.
Americans are faced with health complications such as stroke each and every day. Stroke, also called “brain attack” is the third leading cause of deaths in the United States, killing more women each year than breast cancer. According to World Health Organization, fifteen million people suffer from stroke worldwide each year and about 700,000 in the United States. Among the people, it can be inferred that there is a poor public awareness of stroke. There are also many myths about stroke and one of them states that stroke is not preventable. It is also said that strokes cannot be treated, can only strike the elderly and its recovery happens for a few months post-stroke. When in reality, about 80% of strokes are preventable, it requires critical emergency treatment, can happen to anyone of any age, and occurs in the brain. It is also imperative to know that its recovery can continue throughout life.
Due to the lose in brain cells sometime facial nerve can become damage. Which is also a sign of a stroke. In stroke patient usually when ask to smile, only half of their facial muscle would be able to do so. While the other half remain drooped. The Circulatory system is affect as well. Remember in a Hemorrhagic stroke a ruptured blood vessel begins to bleed out into the brain. Once blood is secreted out side the blood vessel into the tissues, red blood cells will take away nutrient from the brain cells. In Ischemic, the blockage in the blood vessel does not allow the blood to circulated proper. As a result of lost blood supply brain cells will die in the area where it is not receiving nourishment. Traveling in our bloodstream is oxygen and glucose, which is constantly need for cells to preform they daily functions.
The patient’s experience relates to the concept of Perfusion since blood clots may interfere with adequate blood flow. Ischemic stroke is a sudden loss of function resulting from disruption of the blood supply to a part of the brain (Brunner and Suddarth, 2010). The presence of partial blockage of the blood vessel can be due to vasoconstriction, platelet adherence, or fat accumulation and therefore decreases elasticity of vessel wall leading to alteration of blood perfusion with the initiation of the clotting sequence. This may later lead to the development of thrombus which can be loosened and dislodged in some areas of the brain such as mid cerebral carotid artery th...
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.
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.
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
Strokes are not only the leading cause of mentally disabling adults, but they are also the third most common reason for deaths worldwide (Jarvis, 2012). In general, a stroke, also called a “cerebrovascular accident,” occurs when blood flow of the vascular system is blocked from reaching parts of the brain (Jarvis, 2012). There are two types of stroke, an ischemic stroke or a hemorrhagic stroke, and they differ in the way they affect the vascular system. An ischemic stroke is the most common type of stroke, accounting for 80 percent of all strokes, and it is due to a thrombus or embolus blocking blood vessels supplying the brain (Durukan & Tatlisumak, 2007). A hemorrhagic stroke is less common, but is caused by the rupturing of a blood vessel in the brain and causes bleeding (Jarvis, 2012).
A stroke is the acute neurologic injury that come as a result of an effect of ischemia or haemorrhage of the encephalon. Ischemia is caused by diminished supply of arterial blood which carries sugar and oxygen to brain tissue. Haemorrhagic stroke is due to intracerebral or subarachnoid bleeding and it damages the brain directly at the site of the bleeding by compressing the encircling tissue. Ischemic strokes can be embolic or thrombotic. Thrombotic stroke consequences from clot formation in the arterial blood vessel that provides blood to the encephalon, and can bear upon either large vessel or small vessel.
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
The aim of the study was to identify how physically active Stroke patients are during the acute stages following Stroke since, the amount of physical activeness in medically stable Stroke patients was identified as one of the factors crucial for promoting later stage functional recovery. In the Intensive care units and post acute medical wards studied, the amount of physical activity levels demonstrated by Stroke patients were low - provided the medical limitations. They were active only 30% of the time. The remaining 70% was spent inactive in activities like sleeping, lying in bed, chatting, watching tv, being turned, being shifted, being fed and passive exercise of the affected limb.
