Essay On Crebrovascular Accident

Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke.

If the oxygen supply to the brain fails, brain cells may die. The symptoms of vascular dementia can occur either suddenly, following a stroke, or over time, through a series of small strokes.

As mentioned above, strokes are pathophysiological changes. Ischemia which accounts for 87% of all strokes is a decrease or absent circulating blood which deprives neurons of necessary substrates. As there is no storage of glucose in the brain it leaves no opportunity for the chief ingredient for energy substrate and is incapable of anaerobic metabolism (Shah, MD, n.d.). Ischemia is a medical condition diagnosed when tissues do not have a sufficient oxygen supply, therefor resulting in a decrease in ATP energy, leading to necrosis of tissue. Decreased oxygen supply to tissue (ischemia) is caused by a blockage in an artery mainly from an embolism. An embolism is the breakage of an atherosclerosis formed in any coronary arteries. This floats freely in the blood stream, which eventually may plug a major artery in the brain (stroke), heart (MI) or lungs (lung failure). A thrombus occurs when an already

The stroke from a blocked artery is called ischemia, and the ruptured artery is hemorrhagic. As time is critical after the cerebrovascular accident, lack of treatment will lead to brain cell apoptosis and neural injuries are permanent. Evaluation using brief tests of cognitive impairment includes analysis of executive functioning, memory, language, and visuospatial performance, neuropsychiatric as well as depressive symptoms (Grant and Adams, 2009).

A CVA occurs when a part of the brain is damaged or destroyed due to an interruption of blood flow to the area resulting in brain cell death (Martini, Nath & Bartholomew 2015 pp. 496-470).There are two main types of a CVA, Ischaemic stroke and Haemorrhagic stroke (AIHW 2013). The most common cause of stroke is ischaemic, which can be caused by embolism/thrombosis (AIHW 2013). An embolism/thrombosis occurs when there is a clot in an artery or vein, which stops blood flow to the brain (AIHW 2013). A haemorrhagic stroke is when an artery ruptures and bleeds into the surrounding brain tissue (AIHW 2013). This form of stroke occurs when blood pools and forms a clot therefore putting pressure on the area of the brain depriving it of oxygen and nutrients it needs to remain healthy (AIHW 2013).

It is “a sudden loss of function resulting from disruption of the blood supply to a part of a brain” (Hincle & Cheever, 2014). The type of stroke Patient S experienced was assumed to be from hyperlipidemia. An atherosclerotic plaque can form in the large blood vessels in the brain. When the plaque become big enough, it can rupture or a small bit may break off and flow into small arteries, which may block the smaller artery. If the artery is occluded, blood cannot flow to certain parts of the brain and an ischemic stroke can occur. Hypertension is a major risk for strokes as well as atrial fibrillation. These diseases increase the risk of an emboli or plaque

Hemorrhagic stroke is, the less common types of CVA, nearly 13% is all stroke cases and is a result from bleeding into the brain tissue itself (Intracerebral and intraparenchymal hemorrhage) or into subarachnoid space or the ventricles (subarachnoid hemorrhage or intraventricular hemorrhage). This type of stroke is further subdivided into:

brain is damaged by diseases, such as Alzheimer 's disease or a series of strokes.

Cerebral Vascular Accident also known as a stroke, happens when the artery that supplies the blood flow to your brain becomes substantially blocked or completely blocked ("Overview - Stroke - Mayo Clinic," 2015). Without adequate blood supply the brain cells begin to die or become damaged. It is very important to get medical assistance as soon as you think you may be having a stroke, this will help lessen the damage done to the brain ("Overview - Stroke - Mayo Clinic," 2015).

The topic assigned to me for the health paper is cerebrovascular disease, which is a stroke. Cerebrovascular is really two words combined. Cerebro is the largest part in the brain and vascular is termed as veins and arteries. From those two terms, one can interpret that this disease has to deal with the blood flow that goes on in the brain. According to the Association of Neurological surgeons, cerebrovascular disease is defined as the any disorder that is in the brain is either permanently or temporarily affected by bleeding and even by ischemia (AANS, 2005). It states, “ Cerebrovascular disease includes stroke, carotid stenosis, vertebral stenosis and intracranial stenosis, aneurysms, and vascular malformations” (AANS, 2005). When this
