Dementia with Lewy bodies is closely related to Parkinson's disease and often has some of the same symptoms, including difficulty with movement. Front temporal dementia (including Pick's disease) – In front temporal dementia, the front and side parts of the brain are damaged over time when clumps of abnormal proteins form inside nerve cells, causing them to die. At first, changes in personality and behavior may be the most obvious signs. Depending on where the damage is, the person may have difficulties with fluent speech or may forget the meaning of words or objects. 2) Memory problems are usually the most obvious symptom in people with dementia.
Unit DEM 301 Understanding the neurology of dementia: 1.1 A common misconception is that Dementia is a normal part of the ageing process. Dementia is a broad-spectrum term for a range of progressive diseases that generally affect memory, emotional and sometimes physical ability. Dementia is ultimately caused by damage to the brain cells, this damage then causes miscommunications within the brain. When the brain cells do not then work together as usually this can have an effect on an individual’s thinking, abilities and behaviour. Dependent on the type of damage to the cells and the particular regions that are affected this can indicate through investigations (i.e brain scans….)
Rachel Pearson Unit 13: Understanding the Process and Experience of Dementia Unit Code: DEM 301 Unit reference number: J/601/3538 Section 1 - Understand the neurology of dementia 1.1 Describe a range of causes of dementia syndrome? Dementia syndrome is a group of signs and symptoms, in which cause damage to cells in the brain. The most common causes are neurodegenerative diseases; this includes Alzheimer’s, Vascular, and Frontotemporal, lewy bodied, Creutzfeldt - Jakob disease (CJD) and Huntington disease. With these diseases the brain cells degenerate and die more quickly than the normal ageing process. This leads to the decline of a person’s mental health and sometimes physical abilities.
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 injury 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.
Unit 533 - Understand the process and experience of dementia Learning outcome 1 - Understand the neurology of dementia 1. Describe a range of causes of dementia syndrome There are many different forms of dementia and each has its own causes. Dementia may also be a symptom that develops in the later stages of some illnesses. Some of the most common forms or causes of dementia include: • Alzheimer’s disease • Vascular dementia • Parkinson’s disease • Dementia with Lewy bodies • Huntington’s disease • Alcohol related dementia – Korsakoff’s syndrome • AIDS related dementia • Fronto Temporal Lobar Degeneration (FTLD) • Creutzfeldt-Jakob disease. Alzheimer’s disease Alzheimer’s disease is the most common form of dementia and accounts for between 50 and 70 per cent of all cases.
This causes a gradual decline in mental ability. The key functions of the brain that are affected by dementia are the temporal lobe, frontal lobe, parietal lobe, occipital lobe, cerebrum lobe and the hippocampus 3. Depression, delirium and age related memory impairment share a lot of the symptoms of dementia. For instance with depression their memory may be affected and they may find it difficult to retain new information, also it is quite common for people to become forgetful as they age. This may be why people mistake them for dementia.
This may be as a result of a stroke or mini strokes although it can be caused by preventable conditions such as high blood pressure, diabetes and high cholesterol. Dementia with Lewys Bodies (DLB) is caused by small deposits of proteins found in the nerve cells of the brain. Their presence in the brain leads to the degeneration of brain tissue. This is the third most common form of dementia. Rarer forms of dementia are: Fronto temperal dementia which is brain damage usually focused in the front or temporal parts of the brain.
Ways to Recognize Alzheimer’s Disease General Purpose: To inform Specific Purpose: To describe to my audience through communication an overview of ways research has detect Alzheimer’s disease. Central Idea: Alzheimer’s is described as a progressive disease that worsen over a number of years. The symptoms of this disease changes the way people communicate with people who have it. Introduction: I. Attention Getter: Have you ever thought about what it would be like if our bodies aged but not our brains after a certain time?
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.
