UNDERSTAND THE PROCESS AND EXPERIENCE OF DEMENTIA

1.UNDERSTAND THE NEUROLOGY OF DEMENTIA
1.1Describe a range of causes of dementia syndrome.
Dementia is a word used to describe a group of symptoms including memory loss, confusion , mood changes, and difficulty with day-to -day task. There are many causes of dementia wit Alzhaimer`s the most common.
Alzhaimer`s disease-around 500.000 people in the UK have Alzhaimer`s.Scientists know that during Alzhaimer`s two abnormal proteins build in the brain. They form clumps called either "plagues" or "tangles". Theses plagues and tangles interfere with how brain cells work and communicate wih each other. The plagues are usually first seen in the area of the brain that makes new memories.
Vascular dementia-second most common cause of dementia after Alzhaimer`s disease. It can occur when blood flow to the brain becomes reduced.Some people have Alzhaimer`s and Vasular dementia -called mixed dementia
Vasular dementia is sometimes split into more specific types: -stroke -related dementia . This includes multi-infarct dementia (MID), wich happens after a series of small strokes. It also includes dementia which happens after a stroke(called post-stroke dementia). -subcortical vascular dementia( also called binswonger`s disease,small vessel disease related dementia or laccunar state). This is coused by changes to very small blood vessels in the brain.
Vasular dementia is caused by a reduction in blood flow to the brain. Blood carries essential oxygen and nourishment to the brain and, without it, brain cells can die. The network of blood vessels that carries blood around the body is called the vascular system. There are a number of different ways that blood vessels in the brain can become damaged , leading to vascular dementia.
Stroke related-when part of the brain become damaged following a stroke -may caused difficulties in moving, problem wit coordination, speech and sight depending on the part of brain

    Vascular dementia or "multi-infarct dementia" is dementia caused by problems in the supply of blood to the brain, typically by a series of minor strokes. Vascular dementia is the second most common form of dementia after Alzheimer's disease (AD) in older adults. Multi-infarct dementia (MID) is thought to be irreversible and it is caused by a number of small strokes or sometimes a large stroke preceded or followed by other smaller strokes. The term refers to a group of syndromes caused by different mechanisms all resulting in vascular lesions in the brain. Early detection and accurate diagnosis are important, as vascular dementia is at least partially preventable.…

    Then there is the blood supply to the brain which is interrupted causing the brain cell to die, and resulting in brain damage. This is vascular dementia which is cause by either lots of small mini strokes or one large stroke as the oxygen and blood is restricted or stopped before reaching the brain cell. There is other more rare causes of dementia caused by depression, brain tumours, thyroid hormone, head injuries, alcohol abuse, Huntington’s disease, Creutzfeldt-Jakob disease, supranuclear palsy and corticabasal degeneration. Some of these causes of dementia can also be dementia-like conditions which may be treatable or non-progressive. So therefore it is imperative that the person is diagnosed by a professional that deals with mental health diagnoses.…

    This illness however is still nowhere near fully understood. There are however a number of different types of dementia and their causes which have been identified in the above. Alzheimer’s is caused by two abnormal proteins that build up into the brain; they form either ‘plaques’ or ‘tangles’. These plaques and tangles interfere with how the brain responds and how the cells work to communicate with each other, the plaques are usually seen in the area were the brain makes new memories there is ongoing research for finding new ways to stop these proteins so they can protect the brain cells from harm. Whereas vascular dementia is the reduction in the blood flow to the brain, the blood carries essential oxygen and nourishment that the brain needs to survive and without it the brain cells can die. The vessels that carry the blood around the body is called the vascular system, there are many ways that these vassals in the brain can be damaged causing vascular dementia such as:…

    CVA (Cerebrovascular Accident), commonly known as a stroke, is a cardiovascular disease affecting the blood vessels that supply blood to the brain. A stroke occurs when a blood vessel that brings oxygen and nutrients to the brain bursts (hemorrhagic) or is clogged by a blood clot or some other mass (ischemic). When a vessel bursts or is clogged it deprives the brain of blood and oxygen it needs. If the brain does not receive the…

    One of the causes of Alzheimer’s is cerebral tissue damage that is cause by cerebral blood flow deficit. This causes primary ischemia which is poor blood circulation due to blockage of blood vessels. The hippocampus has the least amount of blood supply in the brain, and damage to the brain can lead to Alzheimer’s. Dysfunction of axons, nerves, and synapses can also possibly lead to Alzheimer’s (Bremer, Ross, Shaw, Towery, 2012). The loss of a large amount of neurons and dendrites could also be a possible reason for Alzheimer’s to develop. The loss of these things usually occurs in the temporal, parietal, and entorhinal cortexes, hippocampus, and the amygdala. The beta-amyloid deposition also plays a role in causing Alzheimer’s. Never…

    Alzheimer's Disease is a degenerative brain process that produces, usually slowly over time, dementia or senility. It is also known as senile dementia. The brain is disrupted from the way it normally works – mental function becomes impaired -- and the patient's memory, ability to think clearly and sometimes the patient's language is impaired. The causes of Alzheimer's are still not known -- but we do know that the disease produces physical change in the brain. There is shrinking in some areas and widening in the others. When the brain shrinks or widens, connections inside the brain are broken, causing disruption of the electrical signals in the brain. Alzheimer's Disease affects 2-5% of people over 65 years of age and up to 20% of those over 85 years. AD is difficult to diagnose accurately pre-mortem without sophisticated brain imaging systems. Rate of decline varies from patient to patient but 8 years is the average lifespan between diagnosis and death (3-20years) Genetics may play a role; familial AD is a rare inherited form. Other genes eg ApoE4, presenilins and APP mutations are linked to increased risk. Pathology of Alzheimer's Disease Alzheimer’s disease has a very distinct pathology consisting of amyloid plaques, neurofibrillary tangles, and reduction in neurotransmitter levels. In the Alzheimer brain: The cortex shrivels up, damaging areas involved in thinking, planning and remembering. •Shrinkage is especially severe in the hippocampus, an area of the cortex that plays a key role in formation of new memories. Ventricles (fluid-filled spaces within the brain) grow larger. •Alzheimer tissue has many fewer nerve cells and synapses than a healthy brain. Plaques, abnormal clusters of protein fragments, build up between nerve cells. Dead and dying nerve cells contain tangles, which are made up of twisted strands of another protein. Plaques and tangles (shown in the blue-shaded areas) tend to spread through the cortex in a predictable…

    Although dementia as a whole is caused by brain damage, hindering the brains ability to communicate properly, subsets of dementia are linked with different types of brain cell damage according to the region affected (Alzheimer’s Association). Alzheimer’s contains a high number of hallmark abnormalities, including “deposits of the protein fragment beta-amyloid and twisted strands of the protein tau” (Alzheimer’s Association). Vascular dementia is typically caused by strokes and/or instances that cause blood vessel complications, and dementia with lewy bodies contains clumps of alpha-synuclein on the cortex (“Dementia”). Furthermore, there is mixed dementia, Parkinson’s disease dementia, and frontotemporal dementia that all encumber the most…

    The causes of Dementia can be heightened. Most types of dementia are nonreversible. Nonreversible means the changes in the brain that are causing the dementia cannot be stopped or turned back. Alzheimer's disease is the most common type of dementia. Lewy body disease is a leading cause of dementia in elderly adults. People with this condition have abnormal protein structures in certain areas of the brain. Dementia also can be due to many small strokes. This is called vascular dementia. Some other medical conditions that can lead to Dementia are Huntingson’s Disease, Multiple Sclerosis, and Parkinson’s disease. Some causes of dementia may be stopped or reversed if they are found soon enough. Some more causes are brain injury, brain tumor, chronic alcohol abuse, changes in sodium and calcium levels. Dementia usually occurs in older age. It is rare in people under age 60. The risk for dementia increases as a person gets older.…

    Dementia affects the person’s daily functions. Dementia is more commonly seen in older people but is not considered a normal part of aging. Dementia usually occurs in the second half of life, often around the age sixty five. There are several causes believed to lead to dementia. For unknown reasons, it can be caused by the degeneration of the cerebral cortex, the part of the brain which major functions include memory, actions, thoughts, and personality. When these brain cells die, cognitive changes can begin to appear. Other causes of dementia can also be related to various diseases, infections, strokes, head injuries, or even drug and alcohol…
