Aneurysms and Cerebral Vascular Accidents
The brain is the most complex organ in the human body, but perhaps the most remarkable. Our brain is the primary control center, containing billions of nerves that can simultaneously process information from our bodies, operate organs, generate emotions and thoughts, recall and store memories, and controls movement. The brain also contains a lot of blood vessels that feeds the brain with oxygenated blood to keep it going. It something happens to your brain that cuts off the blood flow, your brain will only be able to survive four to six minutes. Even with the brain having several layers to help protect it, it can be injured. Brain injuries can come in various ways with the most common being blunt force trauma. Brain injuries can happen even without blunt force trauma, like aneurysms and cerebral vascular accidents. Aneurysms and CVA happen with or without trauma, but there are several treatment options for it.
Your head has several layers that protect the brain. The first layer you could consider for protection in most people is your hair. Of course some people don’t have hair, so the next protection is the skin. Now to the main protection which is the skull or cranium. Your skull, which is hard bone, is the best protection for any penetrating or blunt force trauma that may accord. It also serves to contain your brain from moving a lot. The cranium consists of four bones: the frontal, temporal, parietal, and occipital (back). In pediatrics, people have to become extra careful with head injuries. Pediatrics baby’s skull is still soft and not fully fused together. Baby’s anterior fontanel will usually fuse together around the age of nine to eighteen months, where the posterior fontanel ...

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.
Globally the leading reason for mortality and morbidity rate is stroke. Nearly twenty million individuals can suffer from stroke annually and around five million individuals won't survive [1]. The developing countries account for a median of 85% of worldwide deaths from stroke [2]. Stroke ends up in practical impairments with a median rate of two hundredth survivors who need institutional care once an amount of three months and 15%-30% are going to be disabled for good [3].
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.

In the United States, 795,000 people will have their first or recurrent stroke. Studies show that 10% of strokes are secondary to intracerebral hemorrhage and another 3% are due to subarachnoid hemorrhage. The frequency of stroke varies with age, sex, ethnicity and socioeconomic status. African Americans and Hispanics have the greatest threat of intracerebral hemorrhage and excess risk is mostly observed in young and middle aged people (Liebskind & O 'Connor,2015).
Stroke units, introduced in the 1950's, have become an established essential component of an effective functioning stroke service, in the modern stroke services provided today. A stroke unit refers to organized inpatient care for stroke patients, provided by a multidisciplinary team that specialise in stroke management. The Stroke Unit Trialists Collaboration (SUTC) has carried out Cochrane reviews on stroke unit trials since 1997. Findings, from random trials and systematic reviews, have shown that the provision of care in a stroke unit can increase a patient’s chances of survival, which enables them to return home and regain independence in activities of daily life (Langhorne et al., 2012). Stroke units seem to benefit
Ischemic stroke is the most common type of stroke, which accounts for approximately 85% of all cases (Rudd et al, 2002). It affects 35 people per 100,000 of the population per year (Coull et al, 2004).

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).
“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...
“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). Quite arguably, the brain is the most significant aspect contained within your body. Since it does control every move your body makes and every word that comes out of your mouth. What can cause a brain aneurysm? Unfortunately, not much is actually known about aneurysms and why they develop in certain people and not in others. Approximately 5% of people living in the United States, have at least one brain aneurysm and are unaware of its presence. Doctors believe that, any person who has a relative who has had a brain aneurysm is susceptible to having one. Studies have shown that people who have had a close relative, such as a parent or sibling con...
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...
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
