The cause of brain cells dying and deterioration of the connectors is not fully known yet. • Vascular dementia is caused by deprivation of oxygenated blood to the brain. Oxygenated blood is carried around the body by arteries and deoxygenated blood is carried through our body in veins. These arteries and veins make our vascular system. When the organ in our body is deprived of oxygenated blood that organ or part of it will die.
As the disease progresses, 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.Vascular dementia: is a form of dementia caused by damage to the brain through deprivation of oxygenated blood. Oxygenated blood is carried through the body and brain through arteries – deoxygenated is carried through veins. Arteries and veins make up part of the vascular system. When an organ is the body is deprived of blood, that organ (or part of it) will 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.
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.
Dementia is the loss of cognitive functioning- thinking, remembering, and reasoning- to such an extent that it interferes with a person’s daily life and activities (AD fact sheet, 2010). AD is a progressive disease of the brain, which is characterized by a gradual loss of memory and other mental functions (Medina xi, pg. 2). As we age our risk of becoming victim to this degenerative disease becomes greater. One out of two Americans
Nina 1 Dementia describes a group of symptoms that are caused by changes in brain function. Dementia symptoms may include asking the same questions repeatedly; becoming lost in familiar places; being unable to follow directions; getting disoriented about time, people, and places; and neglecting personal safety, hygiene, and nutrition. People with dementia lose their abilities at different rates. They are several neurologic disease for which dementia is the major symptom. They are called neurodegenerative disorder simply because they degenerate the nervous system .Alzheimer disease is by far the most common neurodegenerative disorder.The cause of AD are still very unclear.
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.
Vascular dementia can also occur after a major stroke. • Dementia with lewy bodies - lewy bodies are tiny abnormal protein deposits that develops in the brain of people who have this condition. There are many diseases that can cause dementia, many are rare and in many cases the dementia is just part of the problem. Types of memory impairment experienced by people with dementia • Loss of mental ability • Forgetfulness • Not knowing common facts • Being able to put spoken word into context • Being able to understand written words • Being able to complete day to day tasks independently • Being able to think • Reasoning • Movement difficulties • Loss off skill An individual with dementia may process information differently to others due to • Sight • Sound attention • Short term memory • Long term memory • Feel All this contribute to the way people process information when dementia starts to progress the above abilities are effected making it more difficult for a person to process any information that they may come across. The difference between dementia, depression and confusion states i.e.
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.
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]
