There are a number of causes of Dementia, they include:
Alzheimers - is a physical disease that affects the brain. There are nore than half a million people in the UK with the disease. Alzheimers is progress when a build up of proteins in the brain lead to a loss of connection between the nerve cells. This itself causes the death of these nerve cells and the loss of brain tissue. People with alzheimers also suffer from a shortage of chemicals in their brain. Thesse chemicals are used to transmit signals around the brain. Where there is a shortage the signals are not transmitted effectively. This causes the person to have confusion over places and time and also issues with thinking and memory loss. Vascular Dementia – This is the second most common type of demenia. This affects roughly 15% of people in the UK. The word dementia describes a range of symptoms that can include memory loss and difficulties with thinking and sorting out issues. Vascular Dementia symtpons occur when the brain is damaged due to blood supply to the brain. Picks – this is otherwise known as Frontotemporal dementia, It si one of the less common forms of dementia. It is caused when nerve cells in the frontoal lobes of the brain die and the pathways that connect them change. Some of the chemical messengers are lost and in time this causes the frontal and temporal lobes to shrink. This form of dementia causes change in behaviour, personality and difficulited with speaking and understanding simple instructions. Lewy Bodies – are tiny deposits of protein that appear in the nerve cells. There is not a full understanding of why they appear in the brain or why they contribute to dementia. Their presence s linked to the low levels of the chemical messengers and to the loss of connections between nerve cells. With time there is a progressive death of nerve cells and loss of brain tissue. Lewy Bodies are found to be the underlying cause of several progressive diseases affecting the brain and nervous system. The main symptoms of Lewy bodies are movement problems and impaired mental abilities. These can often occur together. The symptons are also similar to those suffered by Alzheimers patients.
There are a number of memory impairment that are commonly experienced by individuals with the various forms of dementia they are as follows:
Decline in memory – this is one of the first signs of dementia. Memory lapses are sometimes mistaken for normal forgetfulness that can increase with old age. In people with dementia it soon becomes apparent that the memory problems are becoming more persistent. This is usually accompanied by changes in thinking and feeling that make it more difficult to cope with. Memory loss affects each person differently. Some people can recall their earlier years with precise detail but forget the most recent of events including what they have done that day. Each person is different. Sometimes a persons forgetfulness could put them at risk but there are precautions that you can take to assist them to live safely. Such as leaving written reminders by the door so they don’t forget to lock it and take their keys, fitting devices so the gas supply suts off when a pan is left on the stove and forgotten about . we had a client who had a lever which the carers turned on and off when they needed to use the cooker. This was safely hidden in a cupboard where the client could not get to. There are four common areas in which people with memory loss experience difficulty. Theses are remembering events and appointments, taking on board new information, recognising people and places and separating fact from fiction. Changes in behaviour – there are several changes in behaviour that people with dementia can suffer from they incude: Repetitive behaviour. This can include asking the same question over and over again. Its generally a good idea not to mention events and appointments until...
