Ischemic Stroke
Definition of the Disease 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 …show more content…

Mini strokes are a “transient episode of central nervous system tissue ischemia without infarction resulting in a neurological deficit, similar to those observed in an ischemic stroke lasting less than 24 hours” (Laborde, et al, 2012, p.1). Previous TIAs, can be a warning sign of an upcoming major CVA and should be taken seriously (Bansal, et al, 2015). When the cause of a stroke is undetermined it is said to be a cryptogenic stroke. Cryptogenic strokes make up 30-40% of all ischemic strokes (Kent, et al, …show more content…

Right brain damage will affect the left side of the body and cause paralysis, vision problems, a quick impulsive behavioral style, and memory loss. Left brain stroke causes patients to have right side paralysis, speech and language problems, a slow and cautious behavioral style and memory loss. Stroke that occurs in the brain stem may affect both sides of the body. When this occurs, the patient may be in a ‘locked-in’ state. This means that the person is unable to move below the neck and is mostly unable to speak (American Stroke Association,

    The symptoms of a right-hemisphere stroke are very much similar like the symptoms Mr. Fix-it is experiencing. For example, both suggest that functions on the left side of the body are completely neglected; therefore, the left visual section of the body does not respond effectively to stimuli due to the neglect. Damage to the right occipital lobe is very likely. The patient may have experienced some damage to areas 18 and 19 of the occipital lobe. “Damage to these association areas resulted in the patient’s failure to recognize items even when they have been seen before”, such as Mr. Fix-it’s deficiency to recognize geometric shapes (Carlson, 2010). Moreover, the patient could have also experience damage in the frontal lobe, specifically on area 8, in which it could have r...

    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...

    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

  • Sarah's Life Before And After Accident Analysis

    1618 Words  | 4 Pages

    Prior to reading this book, I understood that brain structure and function are related; however, I did not realize how damage to the brain could have such widespread, yet restrained, effects. Sarah’s ability to use the entire left side of her body in movement and sensation was greatly compromised by a brain bleed and damage to the right side of her brain, meaning that different structures must have been affected by the damage; however, Sarah is still able to use the left side of her body if she recognizes it is there and concentrates on using it. With brain injury, I did not realize the extent to which injuries differ. Injuries can occur in different scenarios, such as a car accident, and impact all aspects of life, depending on the severity. The difference between whether an injury hinders or disables a person from performing a function lies in where the damage is done and how tremendous the impact is. Sarah’s injury did not disable her from a task such as seeing, but it did hinder her ability to see anything on or surrounding the left side of her body without concentration. In addition, I was unaware of the existence of hemispatial neglect syndrome. It is an interesting concept because although Sarah still had to ability to see and use the left side of her body with concentration, seeing

    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 Causes and Impacts of Strokes

    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).

  • Taking Care of a Stroke Victim

    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).

  • 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).

    Stroke is a commonly known disease that is often fatal. This cellular disease occurs when blood flow to the brain is interrupted by either a blood clot halting the progress of blood cells in an artery, called an Ischemic stroke, or a blood vessel in the brain bursting or leaking causing internal bleeding in the brain, called a hemorrhagic stroke. When this happens, brain cells are deprived of oxygen and nutrients because the blood cells carrying these essential things are stopped, causing them to die. When the cells in the brain die, sensation or movement in a limb might be cut off and may limit an organism’s abilities. A person with stroke is affected depending on where in the brain the stroke occurs. In other words, symptoms of a stroke

  • A Stroke’s Effect on Memory

    1982 Words  | 4 Pages

    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...

    A stroke can result in ventral and medial frontal lobe damage. Tumors can damage the frontal lobe by being located on one of the lobes, or by causing pressure on the frontal lobe, as is the case with meningioma, subdural hematoma or similarly meningitis (UNL, 2005). Frontal lobe syndrome results in the impairment of language, motor functions, social behavior, abstract reasoning, and cognition. Furthermore, there is often a change in personality (UNL, 2005).
