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 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.
Dementia is an umbrella term for number of diseases; "over 130 are known today" that affect the memory, behaviour, and motor skills. This causes vary depending on the disease, but largely the presence of "plaques and triangles" on the neurons of the brain are found with people with Alzheimer’s. Plaques are proteins that the body no longer breaks down and allows to build up, those get between the neurons that disrupt message transmission. The tangles are tau proteins within the neurons becoming abnormal. Types of Dementia Alzheimer's disease: This is the most common cause of dementia, accounting for about half of all cases.
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.
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.
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.
Over time, however, the damage caused to brain tissue interferes with basic cognitive functions that disrupts everyday activities in their daily lives. Multi-infarct dementia causes loss of functioning to specific areas of the brain, impairing some neurological and mental functions and not others. When vascular dementia occurs with other types of dementia, such as
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]
“Effects and facts of Alzheimer’s Disease and Dementia” Alzheimer’s disease is a progressive disorder involving the degeneration of the brain; mainly affecting brain functions involving an individual’s memory, personality, behavior changes, and thinking. The progressive brain damage and dementia caused by Alzheimer’s disease is irreversible. “Dementia is a term that means a person is no longer able to function on their own (Medical News Today, 2009). Dementia affects a individuals cognitive functions which is the ability to process thought. Dementia can be caused by a number of different medical conditions, and in some cases can be treated.
It is a syndrome (a group of related symptoms) associated with on going decline of the brain and its abilities which include: • Memory loss • Thinking speed • Mental agility • Language • Understanding judgement • Increasing difficulties with tasks and activities that require concentration and planning • Depression • Changes in personality and mood • Periods of mental confusion • Difficulty finding the right words There are many different forms of dementia and they can all affect the way a person communicates. Therefore, in time, an individual with dementia may have to find different ways of communicating and expressing themselves and their feelings as well as people around them adapting the way they communicate with individuals with dementia. This can become very frustrating for the individual and for others around them such as family, friends and care staff who have direct contact with the individual. Your non-verbal communication will become important, your body language, facial expressions, gestures, eye contact and tone of voice will have to be taken into account when you are communicating with an individual with dementia. You must be aware that there will be changes in the way you communicate with an individual with dementia and in some cases
