Cerebral Vascular Accident also known as a stroke occurs when part of the brain loses its blood supply and the part of the body that the blood-deprived brain cells control stops working. Blood loss supply can be ischemic because of lack of blood flow, or hemorrhagic because of bleeding into brain tissue. When an artery in the brain is being obstructed or blocked preventing oxygen rich blood from being delivered to brain cells, an ischemic stroke can occur (Wedro, 2013).
Atherosclerosis can happen when fatty deposits line the vessel walls, which can cause two types of obstruction: cerebral thrombosis which is a blood clot that develops at the clogged part of the vessel; and cerebral embolism that forms at another location in the circulatory system, usually the heart and large arteries of the upper chest and neck (ASA, 2013). …show more content…

The blood accumulates and compresses the surrounding brain tissue. A hemorrhagic stroke is caused by weakened blood vessels that can cause aneurysms and arteriovenous malformations (AVMs) (ASA, 2013).
A ballooning of a weakened region of a blood vessel causes an aneurysm. If not treated properly, the aneurysm will continue to weaken until it ruptures and bleeds into the brain. A cluster of abnormally formed blood vessels is arteriovenous malformation (AVM) and the vessels can rupture, also causing bleeding into the brain (ASA, 2013).
A mini stroke also known as transient ischemic attack (TIA) is caused by a blood clot. Most often it is characterized as a warning stroke. With transient ischemic attack, the blockage is transient which is temporary. Transient ischemic attacks usually cause no permanent injury to the brain, although a transient ischemic attack resolves itself before there is damage, there is no way to predict which clots dissolve on their own (ASA,

    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...

    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 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.

    Atherosclerosis is the most common cause of CAD. Atherosclerosis is a progressive disease characterized by fat deposits in the arteries causing them to block the normal passage of blood. No one is quite sure how atherosclerosis develops. The plaque consists mostly of cholesterol, phospholipids and smooth muscle cells. They also reduce the size of the lumen of the affected artery which impairs the blood flow of this artery and later on could form a thrombus that will completely occlude the vessel. “Unfortunately, signs and symptoms of atherosclerosis usually don’t develop until at least 70% of an artery’s lumen has become obstructed. Angina is almost always the first symptom to appear.”(Journal: The killer behind CAD,2010). Modifiable factors that could prevent the occurrence of CAD include cigarette smoking, obesity, physical inactivity, atherogenic diet like diet high in cholesterol, use of contraceptive and hormone therapy replacement. “Women continue to ...

  • 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).

    Over 1.7 million traumatic brain injuries are reported each year. According to reports the leading cause of brain injuries are from falls followed by motor vehicle accidents, and accidents that were a result of being struck by something. Falls account for 32.5% of traumatic brain injuries in the United States. 50% of all child brain injuries are from falling. 61 % of all traumatic brain injuries among adults are 65 years old or older. Traumatic brain injuries are very violent blows or jolts to the head or body that result in the penetration of the skull. Mild traumatic brain injuries can cause brief dysfunction of the brain cells. Serious brain injuries can cause bleeding, bruising, physical damage to other parts of the body and torn tissues. Brain injuries are more prevalent with males rather than females.

  • Understanding a Brain Aneurysm

    What is a brain aneurysm? One could define a brain aneurysm as bulging, weak area in the wall of an artery that supplies blood to the brain. Over time, weak areas in the walls bulge out causing the blood vessel walls to become weaker as the aneurysm grows (Simon). In most human beings, a brain aneurysm can go undetected for years even possibly ones entire life. Some people however are not so lucky, in some instances, the aneurysm can rupture or explode, causing a hemorrhagic stroke, which is known as the type of stroke that causes bleeding in the brain. It is a known fact that approximately 8% of all strokes occuring world wide, are caused from 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).

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.

    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

    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...
