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).
In both hemorrhagic and ischemic strokes, blood vessels are compromised, thus blood flow is unable to reach the brain. The restriction of cerebral blood flow results in an insufficient amount of nutrients, such as oxygen and glucose, which are being delivered to the brain. This then deters metabolic and functional processes (Boss, 2010). With the decrease of cerebral blood flow, an “ischemic cascade” is initiated within the cell (Durukan & Tatlisumak, 2007, p. 186). Due to the depleted amount of oxygen and glucose being transported to brain tissue, ATP must be anaerobically produced until oxygen can be supplied. If oxygen and glucose are not supplied in time, ATP stops being made, membrane receptors lose function, glutamate is released and a buildup of intracellular calcium, sodium, and chloride levels results (Boss, 2010). Overtime, if oxygen supply is still unsubstantial, acidosis occurs, which causes free radical formation, mitocho...

In conclusion, genograms identify possible genetic predispositions in acquiring hereditary diseases. The author’s genogram allowed for the reflection of prominent family conditions and presented the opportunity for the author to educate herself on modifying behaviors that can reduce their risk for experiencing a stroke. Additionally, Gordon’s activity-exercise pattern and nutritional-metabolic pattern are applied to assess personal risks involved in a stroke. Through employing the nursing process and implementing Gordon’s functional healthh pattern to assess the elements of a stroke, the author was able create interventions to promote their own healthy lifestyle while symbiotically reducing their risks for suffering from a stroke.
Nowadays, stroke has become one of the major causes of death and lifelong disability in adults
Cerebrovascular Accident a) Overview - definition and the effects of the stroke on the body A stroke is a serious, life-threatening medical condition that occurs when the blood supply to part of the brain is cut off. (http://www.nhs.uk/conditions/Stroke/Pages/Introduction.aspx) This condition is a common cause of death and disability, especially in older people. Some predisposing factors include: • hypertension • atheroma • cigarette smoking • diabetes mellitus It occurs when blood flow to the brain suddenly interrupted, causing hypoxia. The effects include paralysis of a limb or one side of the body and disturbances of speech and vision.
There is progressive vasoconstriction of arterioles until the BP exceeds the upper limit of auto regulation, followed by breakthrough vasodilation, increase in cerebral blood flow, blood-brain barrier dysfunction, and cerebral oedema(Rodriguez-Yanez et al., 2006). Cerebral ischemia results in severely ischemic tissue with failure of electrical activity and ionic pumps (Rodriguez-Yanez et al., 2006) There is increase in the release of the excitatory amino acid glutamate due to electrical failure. (Rodriguez-Yanez et al., 2006) . Glutamate receptors are activated as a result and cause the opening of ion channels that allow potassium ions to leave the cell and sodium and calcium ions to enter. This has a number of physiological effects.
There are many causes of strokes and risk factors that can increase likelihood of stroke. Causes include conditions such as atherosclerosis, also known as plaque build...
LG stated that her family stays well educated regarding their health and family history and if they have any questions about the genetic problems in the family, they will typically research the internet and follow up with their general practitioner. LG, her siblings, and their mother are in good health and are not dealing with major medical matters at this time. Interventions for this family should be tailored to help them keep up on current information about heart disease, diabetes, and cancer, which are the main medical issues in their family medical history, and having a plan that ensures they continue getting regular health checkups. In conclusion, it is important for nurses to have proper training and information in the area of genetics and genomics so that it can be used in daily clinical practice (Thompson & Brooks, 2011). Using this information with clients and conducting a detailed genetic nursing assessment is a valuable component of being an effective health care provider and can help clients recognize, prevent, and/or treat diseases that are unique to their particular family.
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.
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...
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

According to the American Heart Association / American Stroke Association’s About Stroke (2014) “stroke is the number four cause of death and the leading cause of adult disability in the United States” (para.1). On average, a stroke happens every 40 seconds in the United States (Impact of Stroke, para. 1) About 4% to 17% of all patients with stroke experience symptom onset while hospitalized (Cumbler, et al., 2014). This amounts to about 35,000-75,000 in-hospital strokes in the United States annually.
“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 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...
It is a known fact that approximately 8% of all strokes occurring worldwide, are caused by the rupturing of brain aneurysms. Those are the unlucky people, fortunately, about 94% of all brain aneurysms do not rupture at all, and people are able to live their lives normally, just of course being careful not to do anything to severely damage their head (Nisacara). The “brain” is the control center for your body. Your brain receives messages from your body. It also sends messages to other parts of your body” (DeGezelle).
Stroke has been classified as the most disabling chronic disease, with deleterious consequences for individuals, families, and society1. Stroke impacts on all domains in the ICF. The body dimension (body functions and structures), the individual dimension (activity), and the social dimension (participation). All domains influence each other2.
The animals that stroke primarily affects are humans. This is likely caused by risk factors that humans attain, such as cigarette smoking, high blood pressure, diabetes, high blood cholesterol, a poor diet, stroke occurring in ancestors, and physical activity/obesity. Stroke has is also starting to become recognized in cats, dogs, and rabbits. According to the World Health Organization, 15 million people suffer from a stroke worldwide every year. Of the people diagnosed, 5 million die and 5 million are permanently disabled. In the United States, 795,000 suffer from stroke annually. 85 percent of the diagnosed strokes are ischemic and 15 percent of them are hemorrhagic As for the humans diagnosed, three fourths of the people that suffer from a stroke are elderly (over the age of 65). This is caused by raising cholesterol levels and the narrowing of arteries as someone ages. Ethnicity, as well as age can also affect a person’s risk to fall victim to a stroke. Africans have a much higher risk of death from a stroke than Caucasians do. This is partly because blacks have greater risks of high blood pressure, diabetes, and obesity. Research suggests Africans may carry a gene that makes them more salt sensitive, inevitably increasing the risk of high blood pressure. Fortunately, research is still being done to prevent stroke. Rats and mice are primary animal subjects for studying this deadly
