Multiple sclerosis Multiple sclerosis This booklet includes- The symptoms of Multiple Sclerosis The impact of Multiple Sclerosis The signs of Multiple Sclerosis What is multiple Sclerosis? Multiple Sclerosis is a disease that affects the brain and the spine, eventually it ends in not being able to control muscles, loss of vision, not being able to balance, and numbness. When you suffer from multiple sclerosis the brain and spine are damaged by the immune system, this is known as an autoimmune disease. The symptoms- The symptoms affect every person differently, they vary on how much damage has been done to the nerves. Some symptoms include: -visual Problems: the visual problems are one of the first to occur normally.
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.
Beta amyloid is similar to cholesterol and is essential for the brain but an excessive amount inhibits proper brain function. In result recent research suggest that the cerebral cortex, which process visual and spatial information is damage in Alzheimer’s disease patients brains. In addition, areas of the brain, important for memory such as the basal forebrain and hippocampus are affected .As well as decrease level of the neurotransmitter acetylcholine. In the early stage of dementia patient experience memory impairment, lapse in judgment and little change in personality .as the disease progresses, memory and language problem worsen and patient begin to have difficulty performing activities of daily living such as remembering to feed themselves and bath etc….during the last stage of the disease patient begin to lose motor functions and eventually lose the ability to recognize family member and to
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.
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.
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).
Stroke Questions 1) What happens to the body as a stroke occurs? A stroke is when the flow of blood to the brain stops. A stroke causes damage to the brain and brain cells in the immediate area which then begin to die because they are not getting the oxygen and nutrients they need to survive. 2) Name three different types of Stroke? Ischaemic stroke, which is caused by a blood clot that blocks a blood vessel or artery in the brain.
The documentary showed how users experience meth mouth, visibly seem to age, and may experience other complications due to neglected health. The brain areas that are damaged have implications for decreased cognitive function and also the ability to experience pleasure because of the dopaminergic pathways which may be altered (NIDA, 2012). There is also an increased risk of stroke due to increased blood pressure from the effect on the autonomic nervous system, which has implications for brain function and a neurotoxic cascade effect (Buttner, 2011). There are also serious effects on mental health. While taking the drug, many people may experience paranoia and psychosis, but these symptoms may last long after the drug has worn off and have permanent repercussions.
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]
