When an organ is the body is deprived of blood, that organ (or part of it) will die. This is what happens to the brain in vascular dementia. The conditions which can cause these problems are high blood pressure, heart problems diabetes and high cholesterol. Leading a healthy lifestyle is important.Creutzfeldt-Jakob Disease (CJD): is a form of dementia caused by prion which is proteins found in mammals. When these proteins cluster together in the brain they cause brain cells to die.
PT1/3/QQ/030 – Understand the process and experience of dementia Dementia is a term used to cover a number of disorders of the brain; Vascular, Dementia with Lewy bodies, Fronto-temporal dementia and Alzheimer’s disease. There are other causes of dementia which I will also describe. The most prevalent type of dementia is Alzheimer’s; this causes a loss of brain cells, shrinkage in brain tissue, neurofibrillary tangles which are insoluble twisted protein fibres that build up in nerve cells and amyloid plaques, which are insoluble protein deposits that build up around nerve cells. Both cause the brain cells to die off at a faster rate than normal ageing. Alzheimer’s tends to affect the whole of the brain.
Unit 13 Understand the process and experience of Dementia 1.1 Describe a range of causes of the dementia syndrome Dementia is word that describes a group of symptoms such as memory loss, mood changes, confusion and difficulties with day to day tasks. there are four commonly known types of dementia Alzheimer's being the most common. scientists have discovered that with Alzheimer's disease two abnormal proteins build up in the brain they then form clumps which are referred to as 'plaques' or 'tangles' these interfere with how the brain cells work and communicate with one another. these 'plaques' or 'tangles' are usually first found in the part of the brain where new memories are made, so this is why we see short term memory loss occur. Another type of dementia is Vascular dementia this is caused when there is not enough blood flowing through the brain and so essential oxygen and nourishments don't get to the brains cells which causes the brain cells to die.
It is caused by nerve cells dying in certain areas of the brain and the connections between the affected nerve cells deteriorate. As the conditions affecting only or primarily the neurons of the brain, causes gradual but irreversible loss of functions of these cells, Memory loss is one of the earliest symptoms of this disease. Vascular dementia is caused by damage to the brain through deprivation of oxygenated blood causing part or all of the affected area to die. (Series of strokes) Conditions that can cause
Typically, medical social workers work within a hospital or hospice setting or in a skilled nursing facility. Medical social workers work with patients who may be in need of psychosocial help as well as their families. The aim of medical social work is to asses the psychosocial functioning of patients and their families and to intervene as appropriate. Medical social workers assist patients and their families by connecting them to supports on resources within their communities, by providing grief counselling and by helping a patient to expand and strengthen their network of social supports. Medical social workers commonly work in interdisciplinary teams with other professionals such as doctors, nurses, physical therapists, occupational therapists etc.
1. Explain what is mean by the term dementia. Dementia is a group of symptoms caused by specific brain disorders.The common symptoms of dementia are memory loss, changes in behaviour or mood, difficulties with communication. Dementia is progressive, which means the symptoms will gradually get worse. How fast dementia progresses will depend on the individual person and what type of dementia they have.
Vascular dementia - this results from brain cell death caused by conditions such as cerebrovascular disease, for example stroke. This prevents normal blood flow, depriving brain cells of oxygen. Injury - post-traumatic dementia is directly related to brain cell death caused by injury. Some types of traumatic brain injury - particularly if repetitive, such as received by sports players - have been linked to certain dementias appearing later in life. Evidence is weak, however, that a single brain injury will raise the likelihood of having a degenerative dementia such as Alzheimer's disease.
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.
Unit 40 Working With Dementia Milestone 1 P1 + P2 the types of dementia includes Alzheimer's disease, this the most common cause for dementia. Dementia is a group of symptoms associated with a decline in the way the brain functions which affects the memory and the way people behave. In alzheimer's disease there is a large loss of brain cells it is unknown to how it is caused the thoughts to the increased risk of developing this is increasing age, a family history of the condition so in the genes, previous severe head injuries and lifestyle factors and conditions associated with vascular disease, which is also another type of dementia. There is also other forms of dementia such as pick's disease, this is a dementia with Lewy bodies which is also a common form of dementia affecting over 100,00 people, although it affects a lot it is still relatively rare and causes slow shrinking of brain cells due to excess protein build up. The term dementia describes the loss of mental ability associated with gradual death of brain cells.
2.2 Describe the key functions of the brain that are affected by dementia. Key functions of the brain are affected by dementia, conditions will deteriorate as dementia is a progressive brain disease. The main areas of the brain that are affected by dementia in terms of causing difficulties with their functions are: 1) Frontal Lobe – this is the part of the brain that controls behaviour, movement, personality and the interpretation of what is around us 2) Parietal Lobe – this is the part of the brain that controls the language we use, spacial awareness and recognition of places, objects and people. 3) Occipital Lobe – this is the part of the brain that controls eyesight and our ability to see 4) Temporal Lobe – this is the part of the brain that controls our speech, hearing and memory Below are the normal and affected conditions of the brain; Key functions of the brain affected by dementia | Normal Brain Function | Effects of dementia on Brain Function | * The brain is made up of billions of cells. Each cell sends messages to many other cells that send messages to our body * Most cells in the brain are called neurons * Neurons communicate with each other by passing an electrical signal down their arms (axons) * This leads to a release of chemical at the ‘fingertips’ * At the end of the axon (at the fingertips) there is a gap, known as a synapse – message passes on by shooting out a special chemical across the synapse and in to the
