Depending what part of brain this occurs in it will affect the way an individual thinks, remembers, walks and communicates. There is a range of causes of dementia here are son of them: • Alzheimer’s disease is the most common cause of dementia. It is caused by nerves cells dying in certain parts of the brain and the connection between affected nerve cells deteriorates. As dementia progresses it spreads and affects other parts of the brain. The cause of brain cells dying and deterioration of the connectors is not fully known yet.
The cells eventually die and this means that information cannot be recalled or assimilated. As Alzheimer’s disease progressively affects different areas of the brain, certain functions or abilities are lost. Vascular dementia Vascular dementia is the broad term for dementia associated with problems of circulation of blood to the brain. It is the second most common form of dementia. There are a number of different types of vascular dementia.
Optional unit understand the process and experience of dementia. 1.1 Describe a range of causes of dementia syndrome. The causes of dementia vary however all are irreversible changes that have occurred in the brain. The most common causes are called neurodegenerative diseases; these include Alzheimer's, front temporal and Lewy body disease. These diseases cause the brain cells degenerate and die more quickly than the normal ageing process.
1. UNDERSTAND THE NEUROLOGY OF DEMENTIA 1.1 Describe a range of causes of dementia syndrome Dementia syndrome is caused by damage to the brain cells; this damage interferes with the ability of brain cells to communicate each other. The most common causes of dementia are called neurodegenerative diseases, and include Alzheimer’s disease, frontotemporal dementia, and dementia with Lewy bodies. When brain cells can no longer communicate normally, thinking, behaviour and feelings can be affected. Dementia is an umbrella term for number of diseases; "over 130 are known today" that affect the memory, behaviour, and motor skills.
Beta amyloid is similar to cholesterol and is essential for the brain but an excessive amount inhibits proper brain function. In result recent research suggest that the cerebral cortex, which process visual and spatial information is damage in Alzheimer’s disease patients brains. In addition, areas of the brain, important for memory such as the basal forebrain and hippocampus are affected .As well as decrease level of the neurotransmitter acetylcholine. In the early stage of dementia patient experience memory impairment, lapse in judgment and little change in personality .as the disease progresses, memory and language problem worsen and patient begin to have difficulty performing activities of daily living such as remembering to feed themselves and bath etc….during the last stage of the disease patient begin to lose motor functions and eventually lose the ability to recognize family member and to
Lesley Chubick PS124 Introduction to Psychology Alzheimer’s, Disorder of the Brain Unit 7 Assignment The mental disorder I chose for this assignment is on Alzheimers. Alzheimers is a form of dementia that is a disease that attacks the brain’s intellectual functions such as memory, orientation and calculation. This degenerative brain disease attacks one in ten men and women over 60. The question many of us have is what is Alzheimers, what is its effect on the brain and is there a cure? Being a degenerative disease Alzheimers attacks the brain through exponentially greater cell death and tissue loss which results in decreased brain size and brain activity.
DEM 301 Understand the process and experience of dementia 1 Understand the neurology of dementia 1.1 Describe a range of causes of dementia syndrome Alzheimer’s - Alzheimer’s is caused be ‘plaques ‘ and ‘tangles’ developing within the brain which causes the brain cells to die, over time the disease progresses damaging other parts of the brain. To begin with individuals will experience memory loss and problems with word finding, as it progresses individuals may find it hard to communicate, forgetting names and places, become confused and unable to carry out every day living tasks. Vascular Dementia - Vascular dementia is caused by a lack of blood supply to the brain, starving the brain of oxygen which causes brain cells to die, this can be caused by a stroke or mini strokes over a period of time. Individuals with vascular dementia may have paralysis or weakness as in a stroke, have difficulty communicating and become confused, suffer from depression, incontinence problems and memory loss. Mixed Dementia – Mixed dementia is when an individual has Alzheimer’s and vascular dementia, the individual may have symptoms relating to either Alzheimer’s or vascular dementia or a mixture of both.
The cause of Vascular Dementia is when the blood supply to the brain is restricted or stopped, brain cells begin to die, which results in brain damage. Alzheimer's Disease: The cause of this is the brain shrinks over time which
Alzheimer disease is something that is a serious disease it is commonly find in elderly adults and is caused by dementia it is characterized by a major loss of memory and many more cognitive functions. Histopathologically is seen as a presence of neurotic plaques and neurofibrillary tangles. Inflammation in Alzheimer disease, the immune system plays a very important role to development of Alzheimer disease it has a unclear role and it still needs to be understood which part of the immune system might be damaged, Failure may lead to chronic inflammation, which is known as part of the pathology in the brain of individuals with Alzheimer's disease. No one knows exactly how Alzheimer develops yet, there has been many clues as to why it happens.
Over time, however, the damage caused to brain tissue interferes with basic cognitive functions that disrupts everyday activities in their daily lives. Multi-infarct dementia causes loss of functioning to specific areas of the brain, impairing some neurological and mental functions and not others. When vascular dementia occurs with other types of dementia, such as
