The term dementia describes the loss of mental ability associated with gradual death of brain cells. Creutzfeldt-Jakob Disease is also another form of dementia and also huntington's disease which is an inherited disease caused again by damaged brain cells. Creutzfeldt-jakob disease is a rare fatal condition that affects the brain and the damage worsens over time. The common signs and symptoms of dementia include the main symptom, memory loss or a decline in memory which is caused from the brain cells being killed off and the brain cells are the memory ones so once these are gone the ability to remember things is taken away. People's behaviour also changes because of their memory and being unable to remember how to behave.
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.
Outcome 1 Understanding the process and experience of dementia 1.1 Alzheimers is the most common cause of dementia. The chemistry and structures of the brain change leading to brain cells dying during the course of the disease. Vascular dementia can occur after a stroke, or over time through many small strokes, the oxygen to the brain fails and many brain cells die. Fronto-temporal dementia is damage usually in the front part of the brain. Behaviour and personality are affected more than the memory.
3) – Explain why depression, delirium, and age related memory impairment may be mistaken for dementia Depression, delirium and age related memory impairment may be mistaken for dementia because they all share many of the same symptoms as dementia. Symptoms of dementia: Increasing difficulties with tasks and activities that require concentration and planning Memory loss, Depression, Changes in personality and mood, Periods of mental confusion, Low attention span, Urinary incontinence, Stroke like symptoms, such as
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.
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.
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
Outcome 1 – Understand the neurology of dementia Causes of dementia syndrome • Alzheimer’s disease – possibly the most well know cause of dementia Alzheimer’s disease affects around two thirds of the elderly. The disease causes the brain to shrink and the numbers of nerve fibre gradually reduce. • Vascular dementia – this is also is a common cause of dementia. This occurs when there become problems with small blood vessels in the brain and they become damaged. Vascular dementia can also occur after a major stroke.
basics of alzheimer’s disease What it is and what you can do Basics of Alzheimer’s disease Alzheimer’s (AHLZ-high-merz) is a disease of the brain that causes problems with memory, thinking and behavior. It is not a normal part of aging. Alzheimer’s gets worse over time. Although symptoms can vary widely, the first problem many people notice is forgetfulness severe enough to affect their ability to function at home or at work, or to enjoy lifelong hobbies. Other symptoms include confusion, getting lost in familiar places, misplacing things and trouble with language.
1) 1.1 Dementia is progressive declines in cognitive function due to damage are decreased in the body beyond what might be expected from normal aging. 1.2. A) Temporal lobe- responsible for vision, memory, language, hearing, learning. b) Frontal lobe- is responsible for decision making, problem solving and responsible for behaviour and emotions. c) Parietal lobe is responsible for sensory information from the body to also where letters are formed putting this in order and spatial awareness.
