Unit Dem301 Understand the process and experience of dementia
1.1 Describe a range of causes of dementia syndrome
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. There is a range ...view middle of the document...
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. This is exactly what happens in vascular dementia. The conditions which can cause these problems are preventable and include diabetes, heart problems, high blood pressure and cholesterol.
Frontotemporal Dementia is caused by damage to front of the brain, this part of the brain is responsible for language skills, behaviour and emotional responses. This form of dementia includes Pick’s disease and dementia associated with Motor Neurone Disease. Individuals with frontotemporal dementia may have changes in the way they behave, say inappropriate things, become aggressive, lack insight and problems with word finding.
HIV-related cognitive impairment and dementia HIV (human immunodeficiency virus) is an infection that weakens the immune system, making it harder for the body to fight infections and disease. HIV infection can cause a number of different problems with the brain that affect up to half of people with HIV. These include mild cognitive complaints (called neurocognitive impairment) and dementia. Neurocognitive impairment is common in HIV but dementia is much rarer. Before the use of antiretroviral drugs (medication that helps to control HIV), around 20-30 per cent of people with advanced HIV infection developed dementia.
Creutzfeldt-Jakob disease is caused by an infectious protein in the brain called a prion. Sporadic CJD, which normally affects people over 40, is the most common form of the disease. It is estimated that the disease affects about one out of every 1 million people every year. It is not known what triggers sporadic CJD. A more recently identified form of CJD, called variant CJD, is caused by eating meat from cattle infected with bovine spongiform encephalopathy (BSE) and typically affects younger adults.
1.2 Describe the types of memory impairment commonly experienced by individuals with dementia
Memory problems are usually the most obvious symptom in people with dementia. For example, a person with early stages of dementia might go to the shops and then cannot remember what they wanted. It is also common to misplace objects as dementia progresses sometimes memory loss for recent events is severe and the person may appear to be living in the past. They may think of themselves as young and not recognise their true age at first.
Dementia can lead to the individual becoming irritated and moody, more challenging behaviour may develop over time becoming agitated or even aggressive and this may be directed towards their carers and in some cases an individual may become quite dis-inhibited this means that he or she may say or do things quite out of character.
They may become suspicious or fearful of others and in some people delusions (abnormal beliefs) and hallucinations (a false perception of something that is not really there) can occur. Alzheimer’s disease- plaques and...
