Epidemiology Of Stroke Essay

Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.

A stroke is a type of cardiovascular disease that affects the cerebral arteries, those blood vessels that carry blood to the brain. A stroke occurs when one of those blood vessels in the brain is obstructed or ruptures flooding the brain with blood. Depriving blood and oxygen to the brain results in those immediate cells death, causing the brain not to function properly. Once parts of the brain stop functioning, it can directly affect the areas of the body controlled (1).

The objective of the present study was to assess the extent of stroke knowledge, specifically regarding the risk factors and warning signs of stroke. Thus, it is important to be well understood about stroke, the risk factors and the warning signs. Furthermore, this review will discuss in details about the two risk factors, stress and obesity that are significant among the studied population. This is followed by the review on the state of stroke knowledge and its importance from the previous studies among varied populations.

A less common type of stroke is a hemorrhagic stroke. This type of stroke occurs when the artery that supplies blood to the brain ruptures or bursts. Stroke is an expensive disease with lifetime rehabilitation costing over $140,000 per ischemic stroke with higher costs for subarachnoid hemorrhage (Alberts, et. al. 2011). Although stroke risk increases with age, strokes can occur at any age. In 2009, 34% of people hospitalized for stroke were younger than 65 years (Hall, 2012). More women than men have strokes each year, in part because women live longer. Estimates of the overall incidence of stroke in U. S. children are 6.4 per 100,000 (0-15 yrs.) with approximately half being hemorrhagic stroke (ASA, 2016). African Americans are more impacted by stroke than any other racial group within the American

Effects - Every stroke is different, and each person that is affected by a stroke will suffer from different problems and have different needs. The way in which you are affected depends on where in the brain the stroke occurs and how big it is. A stroke on the right side of the brain generally causes problems to the left side of the body, and a stroke on the left side of the brain causes problems on the right. The brain is dived into several different areas which control different functions, including movement of the body, language, the way in which you think and senses (touch, sight, smell). Due to different arteries supplying blood to different areas of the brain, where abouts the brain is damaged determines which function is affected. Some strokes occur at the base of the brain which generally cause problems with breathing, moving and eating. These factors impact the effect of a stroke and the recovery after; Type of stroke, which area of the brain is damaged, how much tissue is permanently damaged and the person’s health and level of activity before a

The history of stroke began with Hippocrates, the father of medicine, who was the first one to recognized stroke more than 2,400 years ago. Back then they used to refer as apoplexy a Greek terms, which means “struck down by violent” because at that time they did not have an explanation for it .Century later, in mid-1600’s Jacob Wepfer discovered that something disrupted the blood supply in the brain of people who died from apoplexy. In some cases, the vvartery were blocked. In others, there had been massive bleeding into the brain tissue. After that there was no more progression in the history until 1928. Medical science continues to make advances concerning the causes, symptoms. There is a large amount of information available jon causes, prevention methods, risks and treatment of stroke.

A stroke is when the blood flow to the brain is cut off and oxygen cannot get to the brain. This results in areas of the brain not being able to work

Diagnosing a stroke usually begins with a careful medical history, especially concerning the distribution and onset of the symptoms and the presence of risk factors, so that other possible causes are excluded. Performing a brief neurological exam may be used to identify the location and degree of any deficits, such as vision loss, weakness, or lack of coordination.

Because of the complex anatomy and physiology of the brain and its vasculature, the clinical manifestations of stroke are highly variable. Evidence suggests that gender influences the various clinical presentations of ischemic stroke and how they respond to treatment. 7 Women tend to have a higher overall lifetime risk of stroke as well as higher rates of post stroke disability, depression, and mortality in comparison to men.7 Approximately, 6.8 million individuals in the United States have had a stroke, most of which are women (3.8 million).3

According to the World Health Organization (WHO), the term referred to as a “stroke” is defined as a cerebrovascular accident. This occurs when the blood vessel has a disturbance in its normal flow of blood, usually caused by a clot or rupture in the blood vessel. Following this sudden blockage in the arteries, the brain first starts to lose the exchange of oxygen, nutrients, and vital components which keep it performing optimally, thus leading to death of brain cells (World Health Organization, 2014). Strokes differ in cause and severity. An ischemic stroke is caused by an artery that is totally blocked meaning the brains blood supply is completely cut off. A hemorrhagic stroke is caused by a leaking or ruptured vessel to the brain meaning

Through this article, you can get more information about the stroke symptom. It is very useful because you can deal with the situations for yourself and people

According to American Stroke Association (ASA), stroke is a disease that affects the arteries that lead to the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. As a result, part of the brain cannot get the blood and oxygen it needs which causes brain cells to die (American Stroke Association, n.d.). Depending on where the stroke occurs in the brain, the level/type of impairment differs with the individual. For example, if a stroke occurs in the back of the brain, it is likely that some disability involving vision will result. Overall, the effects of a stroke depend primarily on the location of the obstruction and the extent of brain tissue affected (American Stroke Association, n.d.).

A stroke materializes when oxygen is unexpectedly cut off from the brain occasioning in brain cells dying. There are two chief kinds of strokes. One is when blood clot befalls and blocks the bloodstream decreasing oxygen flow to the brain i.e. this is called as "ischemic stroke". The other one is the "hemorrhagic stroke"

In the U.S, Stroke is a popular leading cause of death. People may say they know someone who has had a Stroke or may have personally experienced one, the thing is it is common for someone to not know exactly what is happening during a stroke. In this essay we will cover the basic statistics and facts about stroke such as, what is it, prevention, how it is treated, survival rates and more. Stroke is a serious thing and if we don’t know how to prevent it, many are at risk.

Strokes are the second leading cause of death in Europe. 1 in 6 people worldwide will have a stroke during their lifetime. A stroke is when there is
