It is caused by nerve cells dying in certain areas of the brain and the connections between the affected nerve cells deteriorate. As the conditions affecting only or primarily the neurons of the brain, causes gradual but irreversible loss of functions of these cells, Memory loss is one of the earliest symptoms of this disease. Vascular dementia is caused by damage to the brain through deprivation of oxygenated blood causing part or all of the affected area to die. (Series of strokes) Conditions that can cause
UNDERSTAND THE PROCESS AND EXPERIENCE OF DEMENTIA Task A 1. For each of the following forms of dementia, describe: • How is the brain affected • The symptoms an individual might experience. Alzheimer's disease is a degenerative brain disease. Most patients start exhibiting symptoms after they reach the age of 60. Alzheimer's disease affects the brain through exponentially greater cell death and tissue loss, resulting in a decreased brain size.
For example, a victim in an accident resulting in head injury may have difficulty remembering anything new. Concussions are a leading cause to anterograde amnesia. It is also a very common type amongst elderly people battling for of dementia, such as Alzheimer’s. In cases of anterograde amnesia, the damage resides in areas of the hippocampus,
3) Other conditions such as depression and delirium both have similar symptoms as dementia. Memory loss can just be a result of ageing, however it is also a symptom of dementia. Understand key features of the theoretical models of dementia. 2.1) The medical model of dementia focuses on the dementia itself. For example it focuses on which type of dementia it is and how it can be treated.
Dementia which begins gradually and worsens progressively over several years is usually caused by neurodegenerative disease that is, by conditions affecting only or primarily the neurons of the brain and causing gradual but irreversible loss of function of these cells. Less commonly, a non-degenerative condition may have secondary effects on brain cells, which may or may not be reversible if the condition is treated. The causes of dementia depend on the age at which symptoms begin. In the elderly population, a large majority of cases of dementia are caused by Alzheimer's disease, vascular dementia or both. It is rare to have dementia in young people 1.2 Describe the types of memory impairment commonly experienced by individuals with dementia.
An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically. A hemorrhagic stroke typically occurs when the blood vessel walls weaken over time, which leads to a bulge or rupture of the vessel. Aneurysm is the most common type of hemorrhagic strokes with a low survival rate. They also kill brain cells, which can never regenerate. The affect of strokes on the body can range between mild dizziness or slight numbness to impaired speech and loss of motor control.
(404) • What is Korsakoff’s syndrome? (438) Being told that you or a loved one has dementia can be very difficult and you may experience a range of different emotions as time goes on. Support is available if you need it. Alzheimer’s Society’s National Dementia Helpline can provide information, support, guidance and signposting to other organisations. Corticobasal degeneration Corticobasal degeneration (CBD) is a rare disease in which parts of the brain become damaged and begin to shrink.
Dementia Awareness Unit 237 Dementia is a condition which is the gradual loss of brain function, this also makes it degenerative. It can include symptoms such as memory loss, confusion, problems with speech and understanding. Dementia at the moment has no cure, as it has a number of diseases that coincide with it. Alzheimer’s is part of dementia. Functions that are affected by dementia are; Short term Memory loss, Language skills, the ability to interpret information, spatial skills, judgement and attention.
Understand the process and experience of dementia Definition of dementia is a syndrome usually of a chronic or progressive nature in which there is deterioration in cognitive function, thinking, orientation, comprehension, and calculation, learning capacity, language and judgement. Dementia is caused by damage in brain. The most common cause of dementia is called neurodegenerative diseases that include Alzheimer’s disease, vascular dementia, Huntington disease, Front temporal dementia and dementia with lewy bodies. With this disease the brain cell degenerate and die more quickly than normal ageing process, these decline a persons mental and some times physical abilities. The gradual changes and damage to the brain cells are caused by a build up of abnormal proteins in the brain.
Dementia can affect the following key functions of the brain: - Temporal lobe - Parietal lobe - Frontal lobe - Occipital lobe - Hippocampus - Cerebrum lobe These all affect the function of: -Memory -Emotion -Cognitive skills -Perception -Behaviour -Communication -Senses and movement 1.3 Explain why depression, delirium and age related memory impairment may be mistaken for dementia. Delirium, age related memory and depression often affect the memory and cognitive impairment, which can be mistaken for dementia. If someone is clinically depressed, their symptoms may be very similar to someone who has got dementia. Delirium, like dementia, is more common in older adults. Depression, delirium and age related memory impairment are all symptoms of dementia.
