Katrina Palmer Stour Valley Community Care Impact of acquired brain injury on individuals Katrina Palmer Stour Valley Community Care Impact of acquired brain injury on individuals Describe with Acquired Brain injury is An acquired brain injury is any sudden damage to the brain received during a person’s lifetime which is not a result of a birth trauma. Acquired brain injuries normally have long term problems in the areas of thinking and behaviour and are not easy to see or recognize like physical disabilities. Identify three possible causes of Acquired Brain Injury * A traumatic injury such as a road traffic accident, a fall or a sporting injury * Stroke * Viral infection, such as meningitis or septacemia Explain
However a limitation of this study is that the sample size is small so would be difficult to generalise because of individual differences in humans. Having said this, since Phineas Gage there have been many other similar case studies that have the same problem, for example Combat Veterans. Neurosurgery is considered an invasive method as it involves manipulating structures within the brain. The main ways neurosurgery performed are by Ablation or Lesions. Ablation involves surgically removing or destroying brain tissue, and observing the behavioural consequences.
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.
Unit DEM 301 Understanding the neurology of dementia: 1.1 A common misconception is that Dementia is a normal part of the ageing process. Dementia is a broad-spectrum term for a range of progressive diseases that generally affect memory, emotional and sometimes physical ability. Dementia is ultimately caused by damage to the brain cells, this damage then causes miscommunications within the brain. When the brain cells do not then work together as usually this can have an effect on an individual’s thinking, abilities and behaviour. Dependent on the type of damage to the cells and the particular regions that are affected this can indicate through investigations (i.e brain scans….)
This may be as a result of a stroke or mini strokes although it can be caused by preventable conditions such as high blood pressure, diabetes and high cholesterol. Dementia with Lewys Bodies (DLB) is caused by small deposits of proteins found in the nerve cells of the brain. Their presence in the brain leads to the degeneration of brain tissue. This is the third most common form of dementia. Rarer forms of dementia are: Fronto temperal dementia which is brain damage usually focused in the front or temporal parts of the brain.
Unit 10 Dementia Awareness Outcome 1 - Understand what dementia is 1.1 Explain what is meant by the term dementia Dementia is a term used that describes a variety of symptoms which affect the brain from certain diseases and conditions such as Vascular and Alzheimer’s disease, these symptoms include losing the ability to remember, think and communicate. Dementia is not an illness or a disease in itself but it is a progressive disorder that affects every person differently. 1.2 Describe the key functions of the brain that are affected by dementia Frontal lobe The largest lobes of the brain and located behind the forehead. The key functions affected by dementia are: behaviour, emotions, decision making, movement and language and interpretation (understanding) Parietal lobe Located behind the frontal lobes in the middle section of the brain, key functions affected are recognition and spatial awareness (being aware of your surroundings) and control of language Occipital lobe Located at the lower back of the head. Key functions affected by dementia are: distortion of the visual field, the perception of size, colour and shape of objects may not be recognised by the brain from what the eyes are actually seeing.
In vascular dementia, changes in thinking skills sometimes occur suddenly following strokes that block major brain blood vessels. Thinking problems also may begin as mild changes that worsen gradually as a result of multiple minor strokes or other conditions that affect smaller blood vessels, leading to cumulative damage. Frontotemporal dementia is one of the less common forms of dementia. The term covers a range of specific conditions. It is sometimes called Pick's disease or frontal lobe
Outline and evaluate the biological approaches to causes of abnormality (12marks) The biological approach to abnormality sees mental disorders as caused by abnormal physiological processes such as genetic and biochemical factors. The physical features of the causes of a mental disorder according to the biological approach suggest that abnormality could be affected by brain damage. Abnormal behaviour may occur if the brain’s structure is damaged in some way. Once the disease or brain damage has caused the mental deterioration there is nothing can really be done to stop the damage going any further. Extreme use of alcohol and other drugs can damage the brain and can sometimes cause hallucinations or other symptoms of a mental disorder but is only usually caused by excessive use of alcohol and drugs.
This build up can cause the head to increase in size. a. If not treated the increased pressure can cause neurological impairment. b. Hydrocephalus can only be determined by getting a MRI or a CT 2. There are many other symptoms associated with Dandy Walker that are not that severe.
Cognitive functions are associated with certain areas of the brain. With the case of Phineas Gage this shows how brain damage can affect a person's cognitive functioning. Though Phineas Gage survived his accident it showed that with certain parts of the brain becoming injured a person's cognitive function is affected. References Kotowicz, Z. (2007).
