1.1. Answer: Dementia is a term for the progressive disease of brain and describes a serious deterioration in mental function, as memory, language, orientation and judgement , The causes of dementia are still not fully understood. Research in dementia is an ongoing and to date number of types of dementia and their causes have been identified. The brain contains billions of cells, in dementia some of these cells stop working properly. Depending what part of brain this occurs in it will affect the way an individual thinks, remembers, walks and communicates.
Unit 4222-237 Dementia Awareness (DEM 201) Outcome 1 – understand what dementia is. 1) Explain what is meant by the term ‘dementia’ The term dementia describes a set of symptoms which include loss of memory, mood changes and problems with communication and reasoning. These symptoms occur when the brain is damaged by numerous certain diseases. Dementia is progressive, which means the symptoms will gradually get worse. How fast dementia progresses will depend on the individual person and what type of dementia they have.
Optional unit understand the process and experience of dementia. 1.1 Describe a range of causes of dementia syndrome. The causes of dementia vary however all are irreversible changes that have occurred in the brain. The most common causes are called neurodegenerative diseases; these include Alzheimer's, front temporal and Lewy body disease. These diseases cause the brain cells degenerate and die more quickly than the normal ageing process.
Unit DEM 201 Dementia awareness Level: 2 Unit DEM 201 Dementia awareness Assessment Criteria Outcome 1 Understand what dementia is The learner can: 1. Explain what is meant by the term ‘dementia’ Dementia is the progressive decline in cognitive function due to damage or disease in the body beyond what might be expected from normal aging. Unlike Alzheimer's disease, which is a specific change in the brain, dementia is more of a generic term that can include many conditions and various causes. 2. Describe the key functions of the brain that are affected by dementia Temporal lobe - responsible for memory, hearing, language, learning and vision.
DEM 301 Understand the process and experience of dementia 1 Understand the neurology of dementia 1.1 Describe a range of causes of dementia syndrome Alzheimer’s - Alzheimer’s is caused be ‘plaques ‘ and ‘tangles’ developing within the brain which causes the brain cells to die, over time the disease progresses damaging other parts of the brain. To begin with individuals will experience memory loss and problems with word finding, as it progresses individuals may find it hard to communicate, forgetting names and places, become confused and unable to carry out every day living tasks. Vascular Dementia - Vascular dementia is caused by a lack of blood supply to the brain, starving the brain of oxygen which causes brain cells to die, this can be caused by a stroke or mini strokes over a period of time. Individuals with vascular dementia may have paralysis or weakness as in a stroke, have difficulty communicating and become confused, suffer from depression, incontinence problems and memory loss. Mixed Dementia – Mixed dementia is when an individual has Alzheimer’s and vascular dementia, the individual may have symptoms relating to either Alzheimer’s or vascular dementia or a mixture of both.
Associated features in DLB are falls, disturbances of consciousness, autonomic dysfunction and rapid eye movement (REM) sleep behaviour disorderFrontotemporal dementia (FTD) usually presents with language disturbance and/or behavioural difficulties (either disinhibition or apathy),Korsakoff's syndrome is a brain disorder that is usually associated with heavy drinking over a long period. Although it is not strictly speaking a dementia, people with the condition experience loss of short term memory.Creutzfeldt-Jakob disease Prions are infectious agents that attack the central nervous system and then invade the brain, causing dementia. The best-known prion disease is Creutzfeldt-Jakob disease, or CJD.HIV-related cognitive impairment People with HIV and AIDS sometimes develop cognitive
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.
The temporal lobe is focused on memory and language, this includes short term memory loss or memory of recent events and ability to explain or describe or think logically. 1.3 - 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 as they have similar effects on a persons behaviour, depression is a mood disorder, delirium is a sudden a severe confusion and rapid changes in brain function that occur with physical or mental illness, delirium is also described as an acute toxic confusional state and cognitive impairment is a loss of ability to think, concentrate and
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
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.
