FINAL EXAM QUESTIONS TYPES OF AMNESIA: There are three types of amnesia; anterograde amnesia, retrograde amnesia, and infantile amnesia. Both anterograde and retrograde amnesia are the most severe types of memory loss disorders. They are caused by damage inflicted on the areas of the brain that provide the functioning of memory. Often, these brain injuries can be a result of severe concussions, traumatic events, and the abuse of alcohol, mental disorders, and disorders that occur from aging. Retrograde amnesia is defined as the loss of memory from the point of injury backwards.
It is caused by nerve cells dying in certain areas of the brain and the connections between the affected nerve cells deteriorate. As the conditions affecting only or primarily the neurons of the brain, causes gradual but irreversible loss of functions of these cells, Memory loss is one of the earliest symptoms of this disease. Vascular dementia is caused by damage to the brain through deprivation of oxygenated blood causing part or all of the affected area to die. (Series of strokes) Conditions that can cause
Alzheimer's disease affects the brain through exponentially greater cell death and tissue loss, resulting in a decreased brain size. As a result, behavior, memory and thinking are affected. Vascular dementia is caused by blockages and breaches in the brain's blood supply that damage the brain and can be caused by any condition which results in an interruption to the blood flow to the brain, and as well as strokes, this could include diseased arteries, heart attacks, high blood pressure, raised cholesterol, diabetes, furred arteries and irregular heart rhythms. Any condition causing damage to the circulation of blood to the brain carries a risk to mental functioning. People experiencing vascular dementia will, like those with Alzheimer’s disease, have problems with learning, remembering, recognition, planning and problem solving.
A stroke or brain infection can also be the cause of dementia. Excessive alcoholic intake results in alcoholic dementia. Use of recreational drugs cause substance induced dementia. Once the over use of these drugs are stopped the injury persists but may not progress. Dementia which begins gradually and worsens progressively over several years is usually caused by neurodegenerative disease that is, by conditions affecting only or primarily the neurons of the brain and causing gradual but irreversible loss of function of these cells.
In addition to this, the connections between affected nerve cells deteriorate. As the disease progresses, it spreads and affects cells in other parts of the brain. Day to day memory problems are first noticed but other symptoms include not knowing the right words anymore, problem solving, decision making or 3 dimensional perception. * Vascular dementia is caused when the brain is deprived of oxygen. This happens when the arteries which carry oxygenated blood to the brain can't get there and the brain, or part of it, dies.
Dementia Awareness Unit 237 Dementia is a condition which is the gradual loss of brain function, this also makes it degenerative. It can include symptoms such as memory loss, confusion, problems with speech and understanding. Dementia at the moment has no cure, as it has a number of diseases that coincide with it. Alzheimer’s is part of dementia. Functions that are affected by dementia are; Short term Memory loss, Language skills, the ability to interpret information, spatial skills, judgement and attention.
It is important to encourage to maintain independence. Know the most common types of dementia and their causes. 3.1) The most common causes of dementia are neurodegenerative disease where the brain cells die more quickly than normal which leads to a decline in the persons mental and physical abilities. Dementia can be caused by strokes, brain damage, old age, or it can be hereditary. 3.2) Symptoms of Alzheimer’s; Becoming more confused and forgetful, Mood swings, Becoming withdrawn due to loss of confidence, Having difficulty completing every
Unit: Dementia Awareness This unit must be assessed in accordance with Skills for Care and Development’s Assessment Principles. Learning Outcome 1: Understand what dementia is Assessment Criteria 1.1. Explain what is meant by the term ‘dementia’ Dementia is a term used to describe a range of signs and symptoms that occur when the brain is affected. Chemical and structural changes in the brain damage and kill brain cells, dementia is a progressive disease and this simply means that the symptoms will gradually get worse. Neurons and synapses become damaged by dementia they may be unable to carry messages that tell a section of the brain what to do.
Dementia with Lewy Bodies can be closely related to Parkinsons Disease and there is a theory that Dementia with Lewy Bodies interferes with two neurotransmitters called dopamine and acetylcholine which assist in the brains functions. In Frontotemporal dementia – Picks Disease, the brain shrinks in the frontal and temporal lobes and a build of specific protein’s occur in these areas. Once the proteins come together, they become toxic and cause brain cells to die. It is not understood why these proteins build up. There are other dementia types too, namely Creutzfeldt-Jakob Disease (CJD) caused by an abnormal infectious protein call Prion which cause nerve damage to
Understand the process and experience of dementia Definition of dementia is a syndrome usually of a chronic or progressive nature in which there is deterioration in cognitive function, thinking, orientation, comprehension, and calculation, learning capacity, language and judgement. Dementia is caused by damage in brain. The most common cause of dementia is called neurodegenerative diseases that include Alzheimer’s disease, vascular dementia, Huntington disease, Front temporal dementia and dementia with lewy bodies. With this disease the brain cell degenerate and die more quickly than normal ageing process, these decline a persons mental and some times physical abilities. The gradual changes and damage to the brain cells are caused by a build up of abnormal proteins in the brain.
