This can be more common in people who have high blood pressure, type 1 diabetes and those who smoke. Also If someone has a stoke it can damage brain cells. However not everyone who has had a stroke will go on to develop vascular dementia. Other less common causes of dementia can be things such as head injuries that can cause memory loss, brain tumours and alcohol abuse which is the cause of korsikof dementia. 1.2 describe the types of memory impairement commonely experienced by individuals with 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.
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).
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.
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.
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. It is a progressive degenerative illness that attacks the brain. As brain cells shrink or disappear, abnormal material builds up as ‘tangles’ in the centre of the cells and ‘plaques’ form outside the cells. These disrupt messages within the brain, damaging connections between brain cells. The cells eventually die and this means that information cannot be recalled or assimilated.
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.
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.
There are different types of dementia. Dementing disorders can be classified in many different ways. These classification schemes attempt to group disorders that have particular features in common, such as whether they are progressive or what parts of the brain are affected. Dementia is diagnosed when two or more brain functions - such as memory, language skills, perception, or cognitive skills including reasoning and judgment - are significantly impaired without loss of consciousness. Dementia is a progressing disease that gets worst with time, for some patients it might take a while but
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.
