Traumatic Brain Injury (TBI) is a result of a sudden blow to the head when an external force is applied causing a disruption of the physiological stability of the brain. It can also occur when an object pierces the skull and enters the brain tissue and when elevation in the intracranial pressure occurs it can potentially change the blood flow within and to the brain. These changes may produce a diminished or altered state of consciousness. Traumatic brain injury is a non-degenerative, non-congenital defect in which there may be permanent or temporary impairment to cognition. TBI or concussions can cause long-term or short-term brain damage among a long list of effects.
Unit 4222-387 Understand the Impact of Acquired Brain Injury 1.1 An acquired brain injury is damage that has been caused to the brain and this can be caused from either by an outside of the brain event or an internal event of the brain. A TBI or ABI, both are a brain injury and the effects are similar but there are key difference in treatment. Acquired brain injury is a sudden change to the brain which was not a birth defect and can happen to an individual at any point of their life. The effects it has on the individual can vary, as well as which part(s) of the brain has been affected can vary. 1.2-1.3 There are 2 types of causes for an acquired brain injury and these will result from either an internal of external event happening.
In a subarachnoid hemorrhage, a blood vessel also bursts, but instead of being on the interior, the vessel is located near the surface of the brain. This increases the intracranial pressure in the skull and can lead to headaches, a decrease in consciousness, and
During an epileptic seizure the regulatory system that maintain the normal balance between stimulation (excitation) and dampening (inhibition) of nerve cell activity break down (Devinsky, 2008). Epilepsy is primarily known for causing convulsions. But, seizures can prompt a large variety of symptoms, from staring to falling to fumbling with clothes. Seizures are divided into two major categories -- focal seizures and generalized seizures. However, there are many different types of seizures in each of these categories.
Now the patient is hyperkalemic from the metabolic acidosis causing dysrhythmias leading to cardiac arrest. (Excited Delirium Strikes Without Warning). Dopamine can be a self-induced problem by taking illegal drugs that block the uptake of dopamine or it can be something the body produces too much of on its own. Wesley goes on to say that, “A large number of these patients who suffer from excited delirium have pre-existing psychiatric conditions…” (Excited Delirium Strikes Without
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.
Migraine headaches, other body changes that affect brain function, medications, depression, family problems and other physiological changes may mimic brain damage. Any changes in interpersonal behavior, attention, foresight and an inhibition of appropriate behavior point to the frontal lobes, usually with damage to the olfactory
Main Idea: The abnormalities in the brain are believed the causes of OCD. 1. Evidence: According to Wikipedia on September 25, 2007, that there is some type of abnormality in the neurotransmitter serotonin. Serotonin is a chemical neurotransmitter that transmits information from one nerve to another throughout the brain. It is released by one nerve ending also known as synapses, and is picked up by another nerve ending.
Two days after the paddling Taylor stated that, “[she] still has welts on her today” (FOX NEWS). Taylor’s punishment caused bruising and blisters. Therefore, the National Association of School Nurses would recognize her case as a form of child abuse. In addition, Taylor’s mother states that the administrator “used too much force” (FOX NEWS). Furthermore, Livestrong.com writes that, “Physical abuse is any act perpetrated upon a child that causes
People with delirium suffer from hallucinations and delutions which means they hear see or think things that are not real, their thinking and reasoning are affected significantly and severe confusion is often present as in most cases of dementia. Age related memory impairment can cause forgetfulness again similar to dementia. The most common causes of different types of dementia are as follows. Alzheimer's disease: Alzheimer's disease is caused by parts of the brain wasting away, which damages the structure of the brain and how it works.It is not known exactly what causes this process to begin, but people with Alzheimer's disease have been found to have abnormal amounts of protein and fibres in the brain.These reduce the effectiveness of healthy neurons, gradually destroying them.Over time, this damage spreads to other areas of the brain such as the grey matter and the hippocampus.
