Understanding Stroke

Diagnosis and Clinical Features of Stroke

Several researchers have attempted to determine the general public's knowledge about stroke risk factors and warning signs. The most commonly cited risk factors were hypertension and stress; the most frequently identified warning signs were dizziness, severe headaches, and unspecified weakness. Knowledge about warning signs may prompt early recognition of strokes and, hence increase the speed and aggressiveness with which people seek medical attention. The five stroke warning signs identified by the National Institute of Neurological Disorders and stroke include: (a) sudden weakness of the face, arm, or leg on one side of the body; (b) sudden dimness or loss of vision particularly in one eye; (c) sudden difficulty speaking or trouble understanding speech; (d)sudden severe headache with no known cause; and (e) unexplained dizziness, unsteadiness, or sudden falls. These symptoms are seen especially in conjunction with other warning signs.

Facts about Stroke

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.

    Ischemic Stroke is caused due to a blood clot in an area of the brain, leading to loss of neural function if last for more than 24 hours. In the United States, ischemic stroke affects 2.7% of men and 2.5% of women of age range 18 years and older. In addition, it has reported that annually about 610,000 and 185,000 of new strokes and recurrent strokes cases occur in US1. Moreover, it has reported that patients who have suffered from a stroke have more chances of recurrent stroke, Myocardial infarction, and death from vascular causes2. One of the risk factor of ischemic stroke is formation of plaque in the blood vessels causing blood clot3. Several randomized trials have also reported that antiplatelet medications are efficient in preventing recurrences of stroke in patients who had an incident of ischemic stroke. Antiplatelet medications for preventing recurrences of stroke are aspirin, combination of aspirin and extended-release dipyridamole, and clopidogrel alone4. It ha...

  • Epilepsy Essay

    Epilepsy, also known as “seizure disorder,” or “seizure attack,” is the fourth most common neurological disorder known to mankind, affecting an estimated 2.3 million adults and 467,711 children in the United States. Unfortunately this disorder is becoming far more common and widespread worldwide. This staggering number of cases of people suffering from Epilepsy also involves an average growth rate of 150,000 new cases each year in the United States alone. Generally, many of the people who develop who are a part of the new are mainly either young children or older adults. Your brain communicates through chemical and electrical signals that are all specialized for specific tasks. However, through the process of communication, chemical messengers, also known as neurotransmitters can suddenly fail, resulting in what is known as a seizure attack. Epilepsy occurs when a few too many brain cells become excited, or activated simultaneously, so that the brain cannot function properly and to it’s highest potential. Epilepsy is characterized when there is an abnormal imbalance in the chemical activity of the brain, leading to a disruption in the electrical activity of the brain. This disruption specifically occurs in the central nervous system (CNS), which is the part of the nervous system that contains the brain and spinal cord. This causes an interruption in communication between presynaptic neurons and postsynaptic neurons; between the axon of one neuron, the message sender and the dendrite of another neuron, the message recipient. Consequently, the effects that epileptic seizures may induce may range anywhere from mild to severe, life-threatening ramifications and complications. There are many different types of seizures associa...

    The electoral college is a system that uses the voice of the states in order to give a presidential running candidate access to the white house. The electoral college should not be abolished because it provides order, equality, and it prevents mistakes being made in order to choose the right candidate. There is so much evidence in history to prove that the electoral college is a well devised system in order to give power to the more qualified individual. The electoral college is an important system formed by the framer of the constitutional in order to keep many things properly aligned, it provides a voice to those who would otherwise be taken for granted, and it limits what “bigger” powers can do in order to avoid tyranny.

  • Treatment of Strokes

    “Time is brain” is the repeated catch phrase when addressing the treatment and management of stroke (Saver, 2006). Access to prompt and appropriate medical care during the first few hours of stroke onset is critical to patient survival and outcomes. Recent changes in the guidelines for acute stroke care released by the American Heart Association (AHA) and the American Stroke Association (ASA) have improved patient access to treatment. Stroke treatment now follows the model of myocardial infarction treatment. Hospitals are categorized into four levels based on stroke treatment capability. The most specialized treatment is available in comprehensive stroke centers followed by primary stroke centers, acute stroke-ready hospitals, and community hospitals. The use of telemedicine now enables even community hospitals, with limited specialized capabilities, to care for stroke patients. Telemedicine puts emergency hospital personnel in contact with neurologists providing expertise in the evaluation of a stroke patient and determination of their eligibility for treatment with thrombolytic medication (Jefferey, 2013).

    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

  • Stroke Foundation Case Study

    500 Words  | 1 Pages

    The Stroke Foundation developed the “Clinical Guidelines for Stroke Management” (2010) to provide evidence-based recommendations for the management of stroke during all phases of recovery and to improve the delivery of care. Therefore, if an intervention or strategy is deemed effective through evidence, it has been recommended in the guidelines, alongside a grading to reflect the reliability of the evidence and the importance of the intervention or strategy. The guidelines are primarily intended for use by policy makers and health care professionals who manage people with stroke in order to improve the quality and effectiveness of the care provided. However, it is essential to not only provide information to the health professionals, but also to the community to prevent or reduce the impact of a stroke. The Stroke Foundation aimed to raise awareness of the 4 common signs of stroke, as well as the impact time has on a person having a stroke in terms of their treatment path and recovery, through their “Think F.A.S.T Act FAST” campaign. The pneumonic F.A.S.T teaches people that signs of face or arm weakness and speech difficulties are stroke signs and prompts them that it is time to act quickly to get medical assistance. Health professionals are also encouraged to inform their patients, friends and relatives of the campaign to prevent the impact of

    The term cerebrovascular accident (CVA), or stroke, is a medical emergency with a sudden onset that can have devastating effects (Bansal, Pelino, Pizzimwnti, 2015). A stroke occurs when blood flow to the brain is interrupted (ischemia), or when a cerebral vessel ruptures and causes blood to bleed into the brain (hemorrhage). Both ischemia and hemorrhage cause brain cell death by depriving the brain of needed oxygen and nutrients. Damaged brain cells die and abilities controlled by that area of the brain are lost (Cook, Clements, 2011). The World Health Organization defines stroke as “Rapidly developing clinical signs of focal or global disturbances of cerebral function lasting more than 24 hours with
