When the neurons get damaged and no longer function efficiently the resulting limitations differ, depending on which side of the brain is damaged. The right side of the brain will cause problems understanding things, and recognizing people and things. Damage in the left side of the brain has been seen to cause by depression, and problems with speech. 1.4 How other factors can cause changes in an individual’s condition that may not be attributable to dementia A variety of
Describe the mechanism(s) by which strokes occur. Cerebrovascular Accident- condition in which brain tissue is deprived of blood supply. The most common stroke symptoms are: • Numbness or weakness (paresis) of the face, arm, or leg, sometimes only on one side; • Confusion, trouble speaking or understanding speech (aphasia) • Trouble seeing • Trouble walking or dizziness; loss of balance or coordination (ataxia) • Severe headache with no known cause 1. Ischemic stroke (~83%)- blood vessel supplying brain tissue is blocked by a blood clot a. cerebral thrombus b. cerebral embolism 2. Hemorrhagic stroke (~17%)- A blood vessel breaks open, causing blood to leak into the brain 3.
Hemorrhagic stroke occurs when a blood vessel located in the brain starts to either leak or rupture. This is usually caused by high blood pressure and weakened walls of the vessel caused by an aneurysm. There are two types of hemorrhagic stroke, intracerebral and subarachnoid. An intracerebral hemorrhage is when an artery in the interior of the brain bursts and the blood moves into the surrounding area causing damage. In a subarachnoid hemorrhage, a blood vessel also bursts, but instead of being on the interior, the vessel is located near the surface of the brain.
Vascular dementia- Vascular dementia is caused by the flow of blood and oxygen to the brain being interrupted causing the death of brains cells, this is called an infarct. Vascular dementia could be caused by a single event such as a stroke, which is known as a single infarct dementia or it could be caused by a series of small events (mini-strokes) over time, known as multiple infarct
Central nervous system disturbances may be noted with decreased cardiac output. •Observe for chest pain or discomfort; note location, radiation, severity, quality, duration, associated manifestations such as nausea, and precipitating and relieving factors. Chest pain/discomfort is generally indicative of an inadequate blood supply to the heart, which can compromise cardiac output. Clients with heart failure can continue to have chest pain with angina or can re-infarct. •If chest pain is present, have client lie down, monitor cardiac rhythm, give oxygen, run a strip, medicate for pain, and notify the physician.
Assessment Task 3 – Independent research project Multiple Sclerosis Definition Multiple Sclerosis (MS) is a disease of the central nervous system where messages between the brain, spinal cord and optic nerves are disrupted. Symptoms and effects include: Motor control problems such as muscle spasms, fatigue, continence problems, and constant pain. The strain of dealing with this condition can result in social and psychological problems for example depression. Other symptoms are cognitive dysfunction and can result in the person having difficulty maintaining a train of thought or keeping up with a conversation when there are too many topics being discussed, and respiratory dysfunction, which courses an impairment of respiratory muscles.

Before most people have full blown strokes there are usually warning signs.Chronic Disease Stroke Outline Introduction: What is a stroke Your brain cells should have a sufficient amount of energy in order to function properly . For any reason if the supply of oxygen is cut short there will definetly be problems of you health. The failure of oxygen and blood suplly to the brain can cause you to have a stroke. 40 percent of the people who have strokes die. Body : What causes a stroke What are the different types and differences of certain strokes : Statistics; There are different tyoes of strokes you can suffer from.
PS124: Introduction to Psychology June 30, 2014 The disorder of the brain that I am interested in is a stroke. Stroke affects more than just the brain as well. A stroke occurs when blood flow to part of the brain is suddenly interrupted or when blood vessel in the brain bursts. Brain cells need oxygen and they die when they no longer receive oxygen and nutrients from blood. When your brain cells die from a stroke, abilities controlled by that area of the brain are lost.
Unit 4222-668 Stroke Awareness 1.1 A stroke is a serious condition which happens when he blood supply to part of the brain is interrupted or when a blood vessel in the brain bursts. It can also be causes by a clot on the brain, but can also be caused by a clot that can travel to the brain through the blood vessels. When oxygen and nutrients from the blood being supplied to the brain are studied stopped then brain cells begin to die and thus stops the brain from working properly. 1.2 Sometimes a stroke can be miss diagnosed or delayed as it starts mild or of a non normal sign or symptom of a stroke. Some of these can be: * Diabetic Hypoglycaemia * Bells Palsy * Migraine Headache * Intracranial Tumour/Abscess * Epilepsy * Some infections such as septicaemia, encephalitis * MS * FND In my role I have seen a couple of occasions when a service user has been miss diagnosed.
An ischemic stroke is usually characterized by a reduction or obstruction of blood supply to the brain due to blocked blood vessels caused by atherosclerosis or a blood clot. Up to twelve percent of ischemic strokes often cause death within thirty days and is among the largest health burdens in developed countries. It is worth noting that the epidemiology of stroke has been changing because of several factors, with the most important being an ageing population, as well as advancements in the treatment of the condition. Stroke prevalence is projected to increase globally as the population of individuals aged above sixty-five years augments (Ovbiagele et al., 2013, p. 2363). Ovbiagele et al.
