Excessive alcoholic intake results in alcoholic dementia. Use of recreational drugs cause substance induced dementia. Once the over use of these drugs are stopped the injury persists but may not progress. Dementia which begins gradually and worsens progressively over several years is usually caused by neurodegenerative disease that is, by conditions affecting only or primarily the neurons of the brain and causing gradual but irreversible loss of function of these cells. Less commonly, a non-degenerative condition may have secondary effects on brain cells, which may or may not be reversible if the condition is treated.
Although there a small amount of cases of Alzheimer’s and frontotemporal dementia can be inherited from a previous generation. Vascular dementia is where the blood supply to the brain is interrupted, if there is restricted or stopped blood supply to the brain that’s when the cells being to die which results in brain damage. * Alzheimer’s disease Alzheimer’s is the most common form of dementia, this form of the disease is the loss of cells in brain which causes the brain to shrink. The medical term for this is ‘Atrophy’. The most affected part of the brain is the Cerebral Cortex; this part
Rarer forms of dementia are: Fronto temperal dementia which is brain damage usually focused in the front or temporal parts of the brain. This tends to affect younger people and men. Types of this dementia include Picks disease and dementia associated with motor neurone disease. It tends to affect personality and behaviour initially, more than memory. The types of memory impairment commonly experienced by people with dementia are: Memory problems such as short term memory or memory recall i.e.
If it is genuine dementia it won't get better. There is medication to ease the symptoms but no cure. 2.1: A medical model for dementia would be when a persons memory is affected by a medical disease or a condition as a result of brain trauma which affects the area of the brain that is responsible for memory. Dementia is an umbrella term that covers a wide variety of ailments that affects a person ability to remember. It can range from a bump to the head to a medical disease that attacks the brains ability to function correctly, such as vascular dementia that alters blood flow to the brain.
Dementia is a syndrome associated with an ongoing decline of the brain and its abilities. This includes problems with: * memory loss * thinking speed * mental agility * language * understanding * judgment People with dementia can lose interest in their usual activities, and have problems controlling their emotions. They may also find social situations challenging, lose interest in socializing, and aspects of their personality may change. A person with dementia may lose empathy (understanding and compassion), they may see or hear things that other people do not (hallucinations), or they may make false claims or statements. As dementia affects a person's mental abilities, they may find planning and organizing difficult.
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.
Dementia is basically damage in the brain where there is a build-up of abnormal proteins which causes a decline in mental ability. The decline can be either rapid or a gradual process. Typical causes of Dementia can be one specific disease such as Alzheimer’s which accounts for 60-80% of cases, or Parkinson’s or motor neurone disease, however Dementia is not a specific disease but rather describes a wide range of symptoms. In most cases, dementia is not inherited directly from family members, although a small number of cases can be inherited from family members. Other less common causes of dementia may include depression, head injuries, alcohol misuse, brain tumours, infections of the brain such as HIV, Strokes, or lack of Vitamin B in the diet.
The cells eventually die and this means that information cannot be recalled or assimilated. As Alzheimer’s disease progressively affects different areas of the brain, certain functions or abilities are lost. Vascular dementia Vascular dementia is the broad term for dementia associated with problems of circulation of blood to the brain. It is the second most common form of dementia. There are a number of different types of vascular dementia.
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.
Catherine SainsburyUnit 4223-316 Outcome 1 Understand the neurology of dementia 1.1 Causes of dementia The term dementia is used to describe the degeneration of the mental and cognitive functions in the brain as a result of various neurological diseases. There are over 100 known causes of dementia, the most common causes are Alzheimer’s disease, which accounts for over 50% of all dementias and vascular dementia, which accounts for approximately 20%. Dementia with Lewi bodies accounts for 4% of all diagnosed dementias but according to new findings accounts for approximately 10% of all dementias. This is because it is often misdiagnosed as other conditions such as Alzheimer’s disease or Parkinson’s disease. 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.
