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.
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.
Outcome 1 Know what a stroke is 1.1 Identify the changes in the brain associated with stroke Heart attacks and strokes are usually due to cardiovascular disease, a condition featuring body-wide damage to the delicate lining of the arteries the tubes that carry oxygen and nutrient-rich blood to all the organs, tissues and cells in your body and to the brain. The psychological, behavioural and emotional changes that take place after a stroke are part caused by physical damage to the brain. When the brain cells are damaged the sensations and parts of the body controlled by the cells can no longer function properly. This usually affects the left hand side of the body. But I personally have seen someone who has had a stroke and it has
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.
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.
The possible causes of a TBI are: * Road Traffic Collisions - Falls & Slips * Domestic Accidents - Assault & Violence * Work Accidents - Sports Accidents Internally is commonly known as an acquired brain injury which has resulted from a medical issue arising thus causing an acquired brain injury (ABI) And these are normally issues that are direct to the brain and are the initial injury to the brain. The possible causes of an ABI are: * Stroke - Brain Tumour * Encephalitis - Hydrocephalus * Haemorrhage - Aneurysm * Hypoxic & Anoxic - Abscess Here are some examples of how some of these ABI’s can occur: * If an
UNIT 4222-365 1.1 Range of causes of dementia Cells in the brain stop working, and the part of the brain that this occurs in will affect how that person thinks, remembers and communicates. The most common forms of dementia are Alzheimer’s disease and Vascular dementia. Alzheimer’s disease is caused by damage in certain areas of the brain. With time, it spreads and affects cells in other parts of the brain. The cause of the brain cells dying and the deterioration of the connectors is not fully known.
Stroke is well defined in the medical lexicon as a disruption of the normal blood flow to a brain region, leading to a loss of neurological function. The common symptoms of a stroke, such as memory loss, speech impairment, and movement problems, occur when neurons die due to the lack of blood reaching them (National Stroke Association). It is important, however, to look beyond the causes or symptoms of stroke, and rather focus on the experience of stroke. What does it feel like to have a stroke? Are patients conscious during a stroke?
Stroke By: Tammy Johnson SCI/162 Submitted To: Ms. Goodwin In the paper we will discuss the etiology of strokes, the age and gender it affects, the symptoms of the disease and its treatment. A stroke is defined as the sudden death of brain cells in a localized area due to inadequate blood flow. Stroke happens when part of the brain’s blood flow is interrupted. If there is no blood to supply to the brain then there is no oxygen or nutrients, nor can waste be removed with that result then brain cells begin to die. A stroke can cause paralysis, speech impairment, loss of memory and reasoning ability, coma and even death.
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
