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.
UNIT 4222-365 1.1 Range of causes of dementia Cells in the brain stop working, and the part of the brain that this occurs in will affect how that person thinks, remembers and communicates. The most common forms of dementia are Alzheimer’s disease and Vascular dementia. Alzheimer’s disease is caused by damage in certain areas of the brain. With time, it spreads and affects cells in other parts of the brain. The cause of the brain cells dying and the deterioration of the connectors is not fully known.
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 main areas of the brain that are affected by dementia in terms of causing difficulties with their functions are: * Frontal Lobe – This is the part of the brain that controls behaviour, movement, personality and the interpretation of what is around us * Parietal Lobe – This is the part of the brain that controls the language we use, spacial awareness and recognition of places, objects and people. * Occipital Lobe – This is the part of the brain that controls eyesight and our ability to see * Temporal Lobe – This is the part of the brain that controls our speech, hearing and memory 1.3 – Explain why depression, delirium and age related memory impairment may be mistaken for dementia. Depression can sometimes be mistaken for dementia because with dementia a person’s behaviour and feeling of well-being can change and cause the person to appear withdrawn and this for example might be mistaken for depression. However, if the person is depressed then it could be the depression not the dementia causing them ill-being. Delirium for example can be brought on as a result of an infection and this might be mistaken with dementia because for example the person could become confused and suffer with
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.
Unit 13: Dementia Awareness 1.1 Explain what is meant by the term ‘dementia’ Dementia is not a natural part of the ageing process. It is a progressive illness with a physical cause. Symptoms are caused due to changes in the brain, the more the brain changes the more the severe the symptoms. Dementia is a set of symptoms that may include memory loss, difficulty thinking, problem solving or language. 1.2 Describe the key functions of the brain that are affected by dementia.
Alzheimer’s disease- Alzheimer’s disease is caused by the build-up of proteins in the brain which form into “plagues and tangles”, these in turn will cause a loss of connection between nerve cells and cause cell death and loss of brain tissue. Early symptoms of Alzheimer’s can be lapses in memory, problems with language (forgetting words or their meanings) and poor visuospatial skill’s (gaging distance, ability to see in 3D). People can also suffer from depression or anxiety, they could become withdrawn and lose interest in daily activities or hobbies or have poor initiation. As the disease progresses sufferers can develop more pronounced memory problems and lose a sense of time and place, they may forget where they are or have difficulties recognising their own family. Vascular dementia- Vascular dementia is caused by the flow of blood and oxygen to the brain being interrupted causing the death of brains cells, this is called an infarct.
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.
UNIT 4222-365 UNDERSTAND THE PROCESS AND EXPERIENCE OF DEMENTIA Outcome 1. Understand the neurology of dementia 1. Describe a range of causes of dementia syndrome Alzheimer’s disease; Vascular dementia; Pick’s disease; Dementia with Lewy bodies (Fronto-Temporal); Creutzfeldt-Jakob Disease (CJD); Huntington’s disease Dementia is a general term for a decline in mental ability severe enough to interfere with daily life. Dementia is a word for a group of symptoms caused by disorders that affect the brain. It is not a specific disease.
PS124: Introduction to Psychology June 30, 2014 The disorder of the brain that I am interested in is a stroke. Stroke affects more than just the brain as well. A stroke occurs when blood flow to part of the brain is suddenly interrupted or when blood vessel in the brain bursts. Brain cells need oxygen and they die when they no longer receive oxygen and nutrients from blood. When your brain cells die from a stroke, abilities controlled by that area of the brain are lost.
