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
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.
Dementia Awareness- Unit 237 Outcome 1-Understand what dementia is Q1- 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. People know it as a disease that affects the mind, which unfortunately affects the elderly. It comes in various forms, for example Alzimers, Parkinson’s and Hunting’s disease and is often a progression from a stroke or develops overtime. Q2-Describe the key functions of the brain that are affected by dementia; The different parts of the brain that is most affected by dementia are the temporal lobe is responsible foe vision, memory, language, hearing and learning, the Frontal lobe is responsible for decision making, problem solving, control behavior and emotions, the Parietal lobe is responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness, the Occipital lobe is responsible for processing information related to vision, the Cerebrum lobe is biggest part of the Brain its role is memory, attention, thought, and our consciousness, senses and movement and the last part is the Hippocampus which is responsible for memory forming, organizing and storing and emotions. Q3- Explain why depression, delirium and age related memory impairment may be mistaken for dementia; Depression, delirium and age related memory impairment is all symptoms of dementia and this may be why people mistake them for dementia.
With any severe injury, there is also usually a short period before the injury and events that occurred prior to the injury for which memory is lost which are often referred to as the retrograde Amnesia. Retrograde Amnesia in particular present interesting problems for any theory of the cerebral mechanism of memory, functioning normally, registration, retention and often recall of experiences all having actually occurred during a period sub sequently covered by a complete amnesia. In Anterograde amnesia patients often will loss memories of experiences that happen after the injury. These amnesias are interesting, because of their variable form and content and also because their time of onset can usually be accurately gauged and their duration measured. In assessing traumatic amnesia, it is usual to measure the post-traumatic amnesia as a period between the injury and the subsequent resumption of normal continuous memory.
These two conditions constitute the vast majority of cases, and although their symptoms can sometimes be managed, they are irreversible. Dementia associated with Altzheimers disease progressively worsens. In addition, symptoms of dementia vary depending on the cause, but it includes some common signs and symptoms such as loss of memory, difficulty in communicating, inability to learn or remember new information, difficulty with planning and organization. The signs of dementia can also include symptoms like difficulty with coordination and motor functions, changes in personality, inability to reason, inappropriate behavior, paranoia, agitation and hallucinations. It is important to know that, dementia affects each person differently, depending on the impact of the disease and the personality of the subject before beginning to suffer it.
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.
How fast dementia progresses will depend on the individual person and what type of dementia they have. Each person is unique and will experience dementia in their own way. It is often the case that the person's family and friends are more concerned about the symptoms than the person may be themselves. The key functions of the brain that are affected by dementia. http://t3.gstatic.com/images?q=tbn:ANd9GcTSqaJFcU1RFX2EAxx7ilgPvdh41FXE_QRBdQBTl5vSTfsKHwHSzQ Temporal lobe = responsible foe vision, memory, language, hearing, learning Disturbance in function of the temporal lobe may be caused by ischaemic or haemorrhagic damage, as with a cerebrovascular event (CVE).
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.

However in most cases patients with semantic dementia, suddenly begin to show symptoms, such as forgetting words for certain objects that are normally recognisable, difficulty in recognising people they don’t see regularly or simply forgetting the meaning of of words, faces and objects. These patients have no difficulty in remembering plans they made for the following day and what time they made those plans at, but rather semantic dementia is forgetting the meaning of things. In most cases it’s people between the age fifty and sixty five that get affected by semantic dementia, however unlike Alzheimer's disease which only affects elderly people, semantic dementia can affect the younger generation just as much as the older generation. When it comes to personality and behaviour traits, patients with semantic dementia tend to adapt a certain daily routine and become inflexible, which lead me to believe that people with semantic dementia could also show traits of Obsessive Compulsive Disorder
Traumatic brain injuries (TBI) occur when an external force causes brain dysfunction. A mild TBI can be a concussion that is caused by a bump, blow or jolt to the head that change the way brain works. It can cause a loss of consciousness for a few seconds to minutes or the person may seem dazed and confused. A change in mental status at the time of the injury or loss of consciousness is the reason a diagnosis of mild traumatic brain injury is made (Brain Injury Alliance Utah). Most people recover from mild TBIs quickly and fully (Center for Disease Control and Prevention, 2013).
