Cerebrovascular Disease Essay

     The most common causes of strokes are thrombosis. This is when a clot forms in one of the arteries, mostly in the carotid in the neck and the vertebral artery. The blood is thick and moves very slowly through the artery. The thrombus will form on the damaged area of the artery wall and will cut off the flow of blood to the brain. The area of the artery that is damaged is cause by arteriosclerosis. This form of

Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.

Mariam background is 60 year old lady admitted with left sided weakness and facial droop. Once confirmed stroke using the Recognition of Stroke in the Emergency Room (ROSIER) scale. Catangui (2015) states ROSIER scale is used to distinguish whether the patient is having a stroke or stroke mimics e.g. seizures or brain tumours. Computed tomography CT brain showed ischemic stroke. Ischaemic stroke is lack of sufficient blood supply to perfuse the brain/ cerebral tissue due to narrowing or blocked arteries in the brain (Morrison, 2014). According to Stroke Association (2015) statics shows that 1520000 strokes occur in the United Kingdom.

“Strokes in young adults […] comprise 10%–15% of all stroke patients, ischemic stroke among young adults was diagnosed in 61% of cases, intracerebral hemorrhage in 17%, and subarachnoid hemorrhage in 22%.

Neuroradiological imaging plays an important role in the process of diagnosing ischaemic stroke. The different imaging modalities that can be used to diagnose ischaemic stroke include computed tomography (CT), magnetic imaging resonance (MRI), and radionuclide imaging. In this article, the different modalities that contribute to the diagnostic process are discussed, with a focus on CT scan protocols.

Strokes are caused by pathophysiological changes. The two major mechanisms of stroke consist of ischemia and haemorrhage. Ischemia is when there is no oxygen or not, merely enough oxygen to fuel the tissue level in the body. Haemorrhage in the brain, causing strokes can be due to non-traumatic intracerebral haemorrhage (Shah, MD, n.d.) (see appendix 1). This essay will further discuss the implications of strokes on a cellular, organ and system level. Explain the clinical presentation of the signs and symptoms of strokes and how the condition will be managed by a paramedic.

Adults and children are both affected by strokes. Strokes are one of the top ten causes of childhood death (Buzzard, 2013, pg. 9). Between 50 and 85 percent of children who have strokes will be affected with long-term health issues (Buzzard, 2013, pg. 9). These health issues may include learning difficulties, seizures and possible recurring strokes (Buzzard, 2013, pg. 9). Up to 20 percent of all strokes occur in people over the age of 55 years old (Buzzard, 2013, pg 7).(DeTallo, 2013)

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

Each year according to National Institute of Neurological Disorders and Stroke more than 700,000 Americans suffer a stroke and about 160,000 die from stroke-related causes. In early 2011 at the American Stroke Association it was reported that the incidence of stroke has rose 51% among men and 17% among women aged fifteen though thirty-four years between 1994-1995 and 2006-2007.

Stroke previously known as Cerebrovascular accident is well-defined as ‘an abrupt cessation of cerebral circulation in one or more of the blood vessels distributing the brain. Due to the interruption or diminish of oxygen supply causes serious damage or necrosis in the brain tissues (Jauch, Kissella & Stettler, 2005). There is a presence of one or more symptoms such as weakness or numbness or paralysis of the face, arm or leg, difficulty speaking or swallowing, dizziness, loss of balance, loss of vision, sudden blurring or decreased vision in one or both eyes and headache. Stoke is categorised into two types, Ischaemic and haemorrhagic

The article “Stroke” by Dr. Colin Tidy, explains that a hemorrhagic stroke is the least common, for it only affects thirteen percent of people but are the cause of most stroke deaths, this meaning many people die when

There are many risk factors associated with stroke. The more risk factors a person has, the greater the chance that he or she will have a stroke. Some of these you have no control of, such as increasing age, family health history, race and gender. But you can change or treat most other risk factors to lower your risk. The chance of having a stroke more than doubles every decade after the age of 55. The chance is greater in people who have a family history of stroke. African Americans have a much higher risk of disability and death from a stroke than whites, in part because blacks have a greater incidence of high blood pressure, a major stroke risk factor. Overall, the incidence of stroke is about equal for men and women. However, at all

First I feel that, it is important to understand the clinical manifestation of the different strokes. The Ischemic stroke can cause a wide range of neurologic symptoms depending on the location and the size of the effective area. Patients may present with symptoms, such as, numbness or weakness of the face, arms, legs, more so, one side of the body, changes in moody or behavior, trouble with speaking or understanding speech, visual disturbances, having difficulty in walking, dizziness or loss of balance and sudden server headaches. Hemorrhagic stroke has, also, presents with the same clinical manifestation as a Ischemic stroke, however, most patients complain of server headache.

Hemorrhagic stroke occurs when a blood vessels in the brain leaks or ruptures. Bleeding from the ruptured brain artery can either go into the substance of the brain or into the various spaces surrounding the brain. The two types of hemorrhagic stroke are Intracerebral and Subarachnoid hemorrhagic.

A stroke caused by a blocked artery by a blood clot or bursting of a blood vessel because of uncontrolled high blood pressure. There are main three types of the stroke. An ischemic stroke occurs when a blood clot blocks one of the arteries which supply blood to brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. (mayo clinic). About 89%, strokes are ischemic strokes. Ischemic stroke includes thrombotic stroke. A thrombotic stroke occurs when a thrombus stuck in one of the arteries that supply blood to the brain. A clot build-up of fatty deposits in arteries. Another type of stroke is called the hemorrhagic stroke. This stroke occurs when a blood vessel leaks or ruptures in the brain. A bold vessel leaks or ruptures from many conditions like uncontrolled high blood pressure or overtreatment with anticoagulants and the weak spot in blood vessel walls. (mayo). Some people experience a mini-stroke it is known as a transient ischemic attack (TIA). A temporary decrease or clot stuck in a vessel in our brain causes TIA. It happens less than five minutes. This stroke does not have any symptom, because the blockage is
