Stroke can be thrombotic (local formation of a clot), embolic a clot traveling from a remote place in the body), or hemorrhagic (bleeding into the brain). Ischemic stroke is characterized by the sudden loss of blood circulation to an area of the brain, reacting in a corresponding loss of neurologic function. Acute ischemic stroke is more common than hemorrhagic stroke, and is caused by thrombotic or embolic occlusion of a cerebral artery.” Hemorrhagic stroke is less common than ischemic stroke and epidemiologic studies indicate that only 8-18% of strokes are hemorrhagic. However, hemorrhagic stroke is more associated with high mortality rates than mortality in ischemic stroke is.” (Broderick, 2007)
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.
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.
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.
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.
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 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.
An entity states that, stroke the extremely important term that accelerates the mortality and morbidity rate in our country. The disabling cerebral tube sickness additionally incorporates an important impact on residual advantages that ends up in the most important economic loss [6]. Though India is rated among the country lacking enough information associated with stroke, a number of the recent studies elucidated the stroke pattern to significant extent in our country with a prevalence rate of 471.58/Lakh population [7].
Nowadays, stroke has become one of the major causes of death and lifelong disability in adults
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
