When the organ in our body is deprived of oxygenated blood that organ or part of it will die. This is exactly what happens in vascular dementia. The conditions which can cause these problems are preventable and include diabetes, heart problems, high blood pressure and cholesterol. Rarer forms of dementia are: • Creutzfeldt-Jakob disease known as CJD is caused by prion disease. Prions are proteins in body and when these protein cluster together in the brain they cause brain cells to die
When an organ is the body is deprived of blood, that organ (or part of it) will die. This is what happens to the brain in vascular dementia. The conditions which can cause these problems are high blood pressure, heart problems diabetes and high cholesterol. Leading a healthy lifestyle is important.Creutzfeldt-Jakob Disease (CJD): is a form of dementia caused by prion which is proteins found in mammals. When these proteins cluster together in the brain they cause brain cells to die.
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.
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. Binswanger’s Disease – Binswanger’s disease is a vascular dementia and is caused by damage to the small blood vessels deep within the brain. Fronto-temporal Dementia – Fronto-temporal dementia is caused by damage to front of the brain, this part of the brain is responsible for language skills, behaviour and emotional responses. This form of dementia includes Pick’s disease and dementia associated with Motor Neurone Disease. Individuals with Fronto-temporal dementia may have changes in the way they behave, say inappropriate things, become aggressive, lack insight and problems with word finding.
Unit 4222-237 Dementia Awareness (DEM 201) Outcome 1 – understand what dementia is. 1) Explain what is meant by the term ‘dementia’ The term dementia describes a set of symptoms which include loss of memory, mood changes and problems with communication and reasoning. These symptoms occur when the brain is damaged by numerous certain diseases. Dementia is progressive, which means the symptoms will gradually get worse. How fast dementia progresses will depend on the individual person and what type of dementia they have.
Another part of the brain that is affected by dementia is the hippocampus as this is ha causes the person to suffer with memory loss as two different types of protein build up and damage the nerve cells. 2.3 Explain why depression, delirium and age related memory impairment may be mistaken for dementia. Depression, delirium and age related memory loss may be mistaken for dementia as they all have very familiar symptoms that interlink with one another. For example memory loss,
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. Because of this behavior, memory and the normal thinking processes are affected.
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
In Dementia some of these cells stop working properly. The part of the brain that this occurs in will affect how that person thinks, remembers and communicates [pic] Alzheimer’s disease is caused by nerve cells dying in certain areas of the brain. In addition to this, the connections between affected nerve cells deteriorate. [pic]
