What causes the health condition?
A stroke is best described as a brain attack (association, 2014) (association, 2014). A stroke occurs when the vital blood and oxygen supply to the brain is cut off (association, 2014). This happens when a blood clot has travelled to an artery in the brain or a blood vessel in the brain bursts causing an interruption in the blood flow to parts of the brain (association, 2014).

What part of the body is affected?
A stroke mainly affects the brain as that is where the problem occurs. Every time a person has a stroke two million brain cells die every minute, this increases the chances of disability, brain damage or even death (association, 2014). However even though the brain is mostly affected, it can cause other serious problems as the brain controls the whole body. It can cause loss of speech, memory, and movement and in more serious cases even paralysis to a side of your body (association, 2014).

What does the health condition include?
A stroke includes the deterioration of brain cells as the brain cells die during a stroke which can cause brain damage and disability (association, 2014). There are two types of strokes Ischemic and Haemorrhagic stroke. The Ischemic stroke occurs when an artery in the brain becomes clotted due to a build-up of plaque or fatty deposits on the artery walls. This is the most common stroke as 87% of strokes are Ischemic in the USA. A Haemorrhagic stroke is when a blood vessel in the brain bursts cause 13% of all strokes and 30% of all stroke deaths (association, 2014).

Statistics
In South Africa there are about 60 people who die because of stroke a day (steyn, 2007) and in the USA someone dies due to stroke every four minutes (association, 2014). There are approximately 240 strokes per day, 87600 a year in South Africa (steyn, 2007) whereas in USA there are2178 stroke a day, 795000 strokes a year (association, 2014).

    The nature and extent of damage depends on the size and location of the affected blood vessels. b) Like all organs, the brain needs the oxygen and nutrients provided by blood to function properly. If the supply of blood is restricted or stopped, brain cells begin to die. This can lead to brain injury, disability, and possibly death. There are two main causes of strokes: ischaemic – where the blood supply is stopped due to a blood clot (this accounts for 85% of all cases) haemorrhagic – where a weakened blood vessel supplying the brain bursts.

    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.

    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...

    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.

    It is caused by clot that blocks blood vessels from supplying blood to the brain through cerebrovascular events. If there is no blood in the brain, then there is no oxygen or nutrients because it is blood that supplies it to the brain. This can cause permanent brain damage which can cause inflammation. Fasting has there been known to be effective and efficient against stroke because it increases cognitive functioning and health of the brain. In addition, fasting has been known to increase neuro-protective proteins and reduction in inflammatory substance known as cytokines. This is critical reducing the chances of damaging the brain that can cause

    There are two major stroke sub groups, those resulting from infarction (ischemic stroke) and those resulting from haemorrhage (intracerebral and subarachnoid). Each of the types can produce clinical symptoms that fulfil the definition of stroke. The types often differ with respect to survival and long-term disability, from recovery in a day to incomplete recovery, severe disability and death (Warlow et al, 2001).

  • Underlying Risks for Cardiovascular Disease

    1649 Words  | 4 Pages

    Since 1960 the age-adjusted mortality rates for cardiovascular disease (CVD) has declined steadily in the U.S. due to multiple factors, but still remains one of the primary causes of morbidity and premature mortality worldwide. Greater control of risk factors and improved treatments for cardiovascular disease has significantly contributed to this decline (Centers for Disease Control and Prevention, 2011). In the U.S. alone it claims approximately 830,000 each year and accounts for 1/6 of all deaths under the age of 65 (Weiss and Lonnquist, 2011). Based on the 2007 mortality rate data an average of 1 death every 37 seconds is due to cardiovascular disease (Lloyd-Jones et al., 2009). Controlling and reducing risk factors is crucial for saving lives. There are a number of contributing risk factors for cardiovascular disease, which may appear in the form of hereditary, behavioral, and psychological, all of which ultimately converge in social or cultural factors.

    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).

    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...

    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 or cerebrovascular accident “effects 800,000 people a year”, the fourth leading cause of morality.1 A stroke is caused by a blockage or a hemorrhage interrupting the blood flow to the brain and depriving the brain of oxygen.2 This lack of blood flow to the brain results in the affected areas inability to properly function, for example, some may have difficulty speaking, understanding, writing or reading language, while others may have paralysis on one side of their body.3 More importantly, a stroke may cause permanent brain damage and death. There are treatable risk factors include smoking, drinking, drugs, high cholesterol, high blood pressure, obesity, and diabetes.1 Other risk factors are previous stroke, being 55 or older, African-Americans, and although, males have a higher risk of having stroke, females are more likely to die of strokes.1
