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. Causes are preventable and include high blood pressure, heart problems, diabetes and high cholesterol. Rarer forms of dementia are Creutzfeldt-Jakob disease (CJD) and Biswanger’s disease. 1.2 Types of memory impairment Whilst long term memory loss is experienced, short term memory loss can cause more problems, although it is not the same in every case.
The memory impairment may result in lack of attention, forgetting language, forgetting names and identity of friends and relatives and lose of ability to solve problems. confusion another effect of dementia, and also disorientation in which the patient forgets the direction, the time (date, month and year) and everything about the self. 1.2 Describe the types of memory impairment commonly experienced by individuals with dementia: dementia is a condition of the brain which causes a
They can forget to take medications, forget that they need to eat or drink or wash and change their clothes. 3.1 The cause of dementia include various diseases or infections, Drugs, head injuries or malnutrition 3.2 Signs and symptoms of the most common causes of dementia include memory loss, personality change, impaired intellectual function. A noticeable decline in communication and signs of depression, learning and remembering things are forgotten. 3.3 The risk factors for the most common causes of dementia include having a family history, smoking, having high cholesterol and drinking large amounts of alcohol. 3.4 4.1 Individuals living with dementia may experience loss of hearing, which can make things difficult for communication and experience feeling frustrated with others causing misunderstanding of commands.
But as the disease progresses it becomes more difficult as the language skills become impaired, which makes it very difficult to understand what they are trying to say. Positive communication can help a person with dementia to maintain their dignity and self esteem. 1.4) Describe how different forms of dementia may affect the way an individual communicates.. All forms of dementia can affect the way a person communicates, so in time they may have to find different ways of expressing themselves and their feelings. In the early stages of some forms of dementia people may have difficulty finding the right words they are looking for so as a carer you use Body language facial expressions, gestures, eye contact and tone of voice n the later stages of some forms of dementia the words could be lost completly. 2.0) Undertand the importance of positive interactions with individuals with dementia.
Unit 4222-365 Understand the process and experience of dementia (DEM 301) Outcome 1 Understand the neurology of dementia 1.1 Describe a range of causes of dementia syndrome Dementia is caused by damage to the brain this can be caused many different ways such as, alcohol or drug abuse, brain injuries, depression, infection (HIV, UTI), vitamin deficiency, certain medications. different types of dementia have different causes for example Alzheimer’s is caused because the body can no longer break down proteins efficiently which affects the transmission of signals in the brain. 1.2 Describe the types of memory impairment commonly experienced by individuals with dementia Memory loss affects people with dementia in different ways but there are four common areas which people with dementia experience difficulties, Remembering events Most individuals who have dementia can remember the distant past more easily than whats happened in the past few months, weeks, days, hours and minutes. This is because memories decline in reverse order making newer information harder to recall. Taking in new information People with dementia find it very difficult to understand and retain new information and events.
This can be caused by a stroke or hardening or thickening of the artery walls which impedes the flow of blood. The vascular system can also be damaged by heart disease, high blood pressure, high cholesterol and diabetes. The brain cells eventually die and this leads to the onset of vascular dementia. If these conditions are treated early enough the onset of dementia may be delayed or even halted. There are different types of vascular dementia and they are dependent on which part of the brain has been damaged and how the damage was caused, as different parts of the brain control different functions of the mind and body.
Dementia Awareness 1.1 Explain what is meant by the term ‘dementia’. A chronic or persistent disorder of the mental processes caused by brain disease or injury and marked by memory disorders, personality changes, and impaired reasoning. 1.2 Describe the key functions of the brain that are affected by dementia. The key functions of the brain that are affected by dementia are the temporal lobe, frontal lobe, parietal lobe, occipital lobe, cerebrum lobe and the hippocampus. 1.3 Explain why depression, delirium and age related memory impairment may be mistaken for dementia.
2 How dementia affects decision-making Dementia is the umbrella term for a number of conditions which cause damage to the brain cells. The most common form is Alzheimer’s disease which has a gradual progression. The next most common type is vascular dementia which has a step-like progression. About one in four people with Parkinson’s disease also develop dementia. Short-term memory loss, disorientation and loss of concentration are common symptoms.
The brain has different regions, each of which is responsible for a different function. When cells in a particular region have been damaged, it can no longer carry out its functions correctly. 2. Types of memory impairment caused by dementia commonly experienced by individuals are forgetting what an item is used for, not remembering knowing a person, begins to use language skills, loses sense of time, impairment of general short term memory, becoming easily lost in familiar surroundings and having little or no awareness of cognitive impairment. 3.
People with delirium suffer from hallucinations and delutions which means they hear see or think things that are not real, their thinking and reasoning are affected significantly and severe confusion is often present as in most cases of dementia. Age related memory impairment can cause forgetfulness again similar to dementia. The most common causes of different types of dementia are as follows. Alzheimer's disease: Alzheimer's disease is caused by parts of the brain wasting away, which damages the structure of the brain and how it works.It is not known exactly what causes this process to begin, but people with Alzheimer's disease have been found to have abnormal amounts of protein and fibres in the brain.These reduce the effectiveness of healthy neurons, gradually destroying them.Over time, this damage spreads to other areas of the brain such as the grey matter and the hippocampus.
