Loss of Consciousness from Brain Injury Versus Amnesia
Brain injuries have been traditionally classified as mild, moderate and severe based upon the duration of loss of consciousness and memory. More recently these classifications have been reconsidered based upon the length and severity of amnesia (4).. How can you measure loss of consciousness and memory? How does the length of amnesia better predict the severity of a brain injury versus the traditional method of classifying brain injury based upon the length of loss consciousness? Head trauma is by far the most common cause of amnesia, but the condition often goes unrecognized as patients more serious medical problems become the foremost concern (3).. Traumatic amnesia is brain damage caused by a severe non-penetrative blow to the head, such as in a road accident. It can lead to anything from a loss of consciousness for a few seconds to coma. During post-traumatic amnesia, a patient usually fails to remember not only the accident, but also all information learned for several years before the brain injury. A severe blow to the head is likely to cause loss of consciousness lasting seconds up to months. This state of puzzlement and confusion can pass with time for many cases (1)..
A brain is exposed to injury as a result of external forces, which are directed to the head. Those forces can include a blow to the head, the head hitting something, and a rapid acceleration/deceleration movement, such as whiplash (2).The extent of brain injury can be classified as either a state resulting in coma or not. This distinction is used not because the ultimate outcomes are necessarily different, but because coma resulting in a head injury can evoke "the vigil between life and death."...

- Greek And Greek Mythology: The Creation Of The Godsanalytical essayIn the beginning there was Chaos, the origin of everything. Then out of the void emerged Erebus (darkness). Until the birth of Eros (love) the world existed in darkness and void. Chaos then gave birth to Gaea (Earth), Nyx (night), and Tartarus (underworld). Alone, Gaea shortly gave birth to Uranus, the sky (Karas, 2017: Megas, 2017). Together they created the Titans, Cyclopes, and the Hecatoncheires. After their births, the Titans produced the twelve gods; the foundation of Greek mythology.

Traumatic brain injuries can be categorized as open or closed. A closed head injury is caused by blunt trauma to the head, and injuries normally result from the brain hitting the skull. An open head injury is usually caused by penetrating trauma in which the skull itself is anatomically altered. A contusion of the brain is defined by bruising of the brain tissue. Bleeding of the brain tissue is called a hematoma or an intracranial hemorrhage according to the size and placement of the bleeding. Brain injuries are formed in three stages. The first stage is called the primary stage when

Accidents can result in forces that jar the skull, causing the brain to strike the skull walls causing bruising or hemorrhaging. In some cases, swelling can lead to herniation in the brain and restricted blood flow that can lead to cognitive impairment. In more severe cases, the result is either a vegetative state or death. Two scales used to measure the severity of TBI are the Glasgow Coma Scale (GCS), which measures from 3 being comatose to 15 indicating minor trauma based on eye, verbal, and motor responses, and the Abbreviated Injury Scale (AIS), whose last number indicates severity from 1, which indicates minor injury, to 6, indicating certain death. Violence, car accidents, work accidents, and sports injuries are well known causes of TBI.

Due to its incredible importance in basic human functioning, both voluntary and involuntary, any injury or trauma to this organ will have a great influence on the body and it's capabilities (Burrus, 2013). Exploring how the brain deals with various injuries and damage proves that the functionality of the brain is fitting to make the brain the power house of the body. But before exploring this with the help of case studies, it is important to first make sense of the the anatomy and functioning of the nervous system as a whole in order to understand how it is affected during injury, the functioning of the body that is lost, the intervention implemented for treatment or rehabilitation and the changes experienced.

It uses unambiguous terms that are readily understood by a wide range of observers. The GCS also facilitates monitoring in the early stages after injury, allowing for rapid detection of complications and decline. Even among mild injuries (GCS 13- 15) the scale can discriminate between those more or less likely to have detectable brain damage and to be at risk of complications (Jannett, 2002, p. 91). Upon arrival to the hospital, the patient was obtunded, eye opening to verbal commands (+3), and incoherently (+3) responded to painful stimuli (+5), giving her a GCS of 8. Minor abrasions were noted to the face, hands, and wrist. After entering the trauma bay, the patient was transferred onto the stretcher and immediately attached to monitoring equipment. Vital signs revealed mild hypotension (112/76) and sinus bradycardia (HR= 47 bpm). Pupils were 2 mm with symmetry with sluggish light reactivity. Her head was normocephalic and a single 1 mm cut was noted to the left temple, dried blood was also noted to the area.

1378 wordsRead More - Exploring Traumatic Brain Injury in Childrenanalytical essayBrain injuries can be classified into mild, moderate, and severe categories. The most commonly used assessment for classifying TBI severity is by using the Glasgow Coma Scale (GCS). This scale assesses individual’s level of consciousness based on verbal, motor, and eye responses to stimuli. Researchers Kung et al (2010) analyzed the components of Glasgow coma scale (GCS) from 27,625 TBI cases in Taiwan. The correlation between the survival rate and certain eye (E), motor (M) and verbal (V) score combinations for GCS (scores of 6, 11, 12, &13) were found to be statistically significant. The findings indicate that the three fundamental elements comprising the Glasgow coma scale (E, M, & V) separately and in some combinations are predictive of the survival of TBI patients. The researchers assert that this observation is clinically useful when a complete GCS score cannot be obtained when evaluating TBI patients.

The injury may be only a small bump on the skull or a serious brain injury. There are two main types of TBI: open head injuries and closed head injuries. Open head injury is penetration of the skull with direct injury to the head, which means being hit with an object that broke the skull and entered the brain. This is more likely to happen when you move at high speed, such as going through the windshield during a car accident. It can also happen from a gunshot wound to the head. A closed head injury means you received a hard blow to the head from striking an object, although the object did not break the skull, it caused the brain to move forward and back or from side to side and
