These changes may not always be permanent dependant on the ABI (Acquired Brain Injury) but most often do cause substantial alterations in the person’s character and physical abilities. ABI's are very complex and no two persons can expect to have the same difficulties, although some of the changes will be similar they are rarely the same. 1.2 Describe possible causes of acquired brain injury. There are many causes of an ABI. Traumatic Brain injury is caused by physical traumas, for example an accident, neurosurgery, head injury or even an assault.
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.
A brain that may have a psychological or biological disorder can help with the understanding of the different areas of the brain. Neuroscience plays a large part of understanding the brain and its role in cognitive functioning. There is also a strong correlation between cognitive functioning in the person's experience the prefrontal cortex is responsible for making social judgments, weighing alternatives, preparing for the future, and keeping behavior under control (Willingham, 2007). Neurological diseases such as Alzheimer's and dementia can have great effects on cognitive function within the brain (Walstein & Elias, 2003). Not neurological diseases are not the only problems the brain cases because biological issues can be the cause for cognitive failures as well (Walstein & Elias,
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. 2.2: This is personal centred, focusing on the rights of the individual, in turn empowering the individual, promoting independence, giving choice and looking at what the individual is able to do. 2.3: Individuals who have dementia are not aware of requirements for living. They can forget to do the
There could be some damage to the central nervous system but not very severe or the symptoms that Nick exhibits would be more severe. C. Diabetic neuropathies damage peripheral nerves. Which component of the reflex arc is most likely to be damaged in Nick’s situation? The component of the reflex arc that is most likely to be damaged in Nick’s situation would begin at the sensory neuron. Stimuli is still triggering the receptor but the information from the sensory neuron doesn’t continue the arc to the integrating centers to the motor neurons to the effectors which causes the absence of a reflex.
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.
The cerebrum also helps in processing memory. There are various cells that are in charge of the memory. When the nerves do not release neurotransmitters it makes it difficult for the brain cells to carry the information from one part of the brain to another. The hippocampus is also responsible for memory processes. It helps the transfer of information from short term memory into long term memory.
As dementia affects a person's mental abilities, they may find planning and organizing difficult. Being independent may also become a problem. A person with dementia will therefore usually need help from friends or relatives, including help with decision making. Most types of dementia can't be cured, but if it is detected early there are ways to slow it down and maintain mental function. Dementia is a collection of symptoms including memory loss, personality change, and impaired intellectual functions resulting from disease or trauma to the brain.
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.
Our brains are terribly fragile, sensitive and often vulnerable to all sorts of injury. Our brain tissue can be damaged by a variety of things like infection, strokes or tumors and any injury to the brain from an external force such as a car accident can result in a traumatic brain injury. Semantic Dementia is not the type of injury caused by an external environment or lifestyle factors such as head injury or a diet. It is a progressive process during which a person gradually loses their ability to remember the meaning of words, names and objects. Damage to the frontal lobe is typically associated with Semantic Dementia.
