Although there a small amount of cases of Alzheimer’s and frontotemporal dementia can be inherited from a previous generation. Vascular dementia is where the blood supply to the brain is interrupted, if there is restricted or stopped blood supply to the brain that’s when the cells being to die which results in brain damage. * Alzheimer’s disease Alzheimer’s is the most common form of dementia, this form of the disease is the loss of cells in brain which causes the brain to shrink. The medical term for this is ‘Atrophy’. The most affected part of the brain is the Cerebral Cortex; this part
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.
Parkinson’s disease; the brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement. As the brain changes, the disease will begin to affect mental functions, including memory and the ability to pay attention, make sound judgements and plan steps needed to complete a task. Parkinson’s disease is a fairly common neurological disorder in older adults, estimated to affect nearly 2% of those over 65. Huntington’s disease; this disease is a progressive brain disorder caused by a single defective gene on chromosome 4. Symptoms of the disease include abnormal involuntary movements, a severe decline in thinking and reasoning skills, irritability, depression and mood changes.
DEM-301 Understand the Process and Experience of Dementia 1.1 Describe a range of causes of dementia syndrome. Fixed cognitive impairments are due to a single incident.traumatic brain injurys may cause generalised damage to the white matter of the brain or localised damages. A brief reduction in the supply of blood and oxygen to the brain may lead to this type of dementia. A stroke or brain infection can also be the cause of dementia. Excessive alcoholic intake results in alcoholic dementia.
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.
This can be caused by a stroke or hardening or thickening of the artery walls which impedes the flow of blood. The vascular system can also be damaged by heart disease, high blood pressure, high cholesterol and diabetes. The brain cells eventually die and this leads to the onset of vascular dementia. If these conditions are treated early enough the onset of dementia may be delayed or even halted. There are different types of vascular dementia and they are dependent on which part of the brain has been damaged and how the damage was caused, as different parts of the brain control different functions of the mind and body.
People with delirium suffer from hallucinations and delutions which means they hear see or think things that are not real, their thinking and reasoning are affected significantly and severe confusion is often present as in most cases of dementia. Age related memory impairment can cause forgetfulness again similar to dementia. The most common causes of different types of dementia are as follows. Alzheimer's disease: Alzheimer's disease is caused by parts of the brain wasting away, which damages the structure of the brain and how it works.It is not known exactly what causes this process to begin, but people with Alzheimer's disease have been found to have abnormal amounts of protein and fibres in the brain.These reduce the effectiveness of healthy neurons, gradually destroying them.Over time, this damage spreads to other areas of the brain such as the grey matter and the hippocampus. Risk factors
1. Understand what dementia is 1.1 Explain what is meant by the term ‘dementia’ Referring to the degeneration (decline) of various functions governed by the central nervous system, including motor reactions memory and learning capabilities, problem solving etc. These functions normally decline with age, but several dementia syndromes result from pathological organic deterioration of the brain. Dementia is a common condition that affects about 700,000 people in the UK. Your risk of developing dementia increases as you get older, and the condition usually occurs in people over the age of 65.
When discovered, these remnants of corrupted brain cells are the primary method today in identifying Alzheimer's disease. Granulovacuolar degeneration is when fluid filled vacuoles are evident in the cells of the hippocampus. The dendrites and nucleus in the cell disintegrate entirely, lost in the body’s disposal system (Talan, 2011). The brain actually loses mass and shrinks. Eventually so much of the brain has been lost that it can no longer support
The term is used for a variety of diseases and conditions when nerve cells (called neurons) in the brain die or function abnormally. It’s the condition of forgetfulness, loss of ability to reason and think clearly. As the population ages more and more people suffer from this disease. The increase in newly diagnosed cases each year proves that it is not possible to ignore this problem any longer. Alzheimer’s
