These plaques and tangles choke the nerve cells and prevent them from working properly. For reason not understood, these plaques and tangles take over healthy brain tissue, which devastates the area of the brain associated with intellectual function (Goldmann, 2010, pg 6). Today, as research on Alzheimer's disease progresses, scientists are describing other abnormal anatomical and chemical changes associated with the disease. These The dangers of Alzheimer’s disease and the signs to look for. 4 include nerve cell degeneration in the brain's nucleus and reduced levels of the neurotransmitter acetylcholine in the brains of Alzheimer's disease victims (Alzheimer’s Disease).
These diseases cause the brain cells degenerate and die more quickly than the normal ageing process. This leads to a decline in a person's mental and physical abilities. Vascular dementia is caused when the blood flow is restricted or stopped, the brain cells will begin to die, resulting in brain damage. The vessels narrow when fatty deposits build up on the blood vessel walls, restricting the flow of blood. This can be more common in people who have high blood pressure, type 1 diabetes and those who smoke.
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.
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.
Glutamate is also a chemical in the brain important for learning and memory.” Patient: “I am happy that there is something that can help me deal with some of these symptoms. I am still a little nervous though; can you talk about the severe stages of Alzheimer’s?” Me: “Well earlier I spoke a little about some of the symptoms in the early stages of Alzheimer’s. Those symptoms will progress to not being able to recognize family, and friends. It will become difficult for you to communicate, and you will need help with everyday activities, like getting dressed, all the way down to taking medication and eating. You may lose control of your bladder and bowel functions.
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.
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.
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.
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.
It occurs when the supply of blood carrying oxygen and nutrients to the brain is interrupted by a blocked, or diseased vascular system. Vascular dementia generally affects people between the ages of 60 and 75, and affects more men than women. The most common type of vascular dementia is multi-infarct dementia (MID), which is caused by a series of small strokes, or “mini-strokes,” that often goes unnoticed and cause damage to the cortex of the brain—the area associated with learning, memory, and language. These mini-strokes are sometimes referred to as transient ischemic attacks (TIAs), that temporarily block blood supply, and briefly impair consciousness or sight. Over time, however, the damage caused to brain tissue interferes with basic cognitive functions that disrupts everyday activities in their daily lives.
