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."...

  • Julius Caesar and the Fall of the Roman Republic

    2913 Words  | 6 Pages

    How was it possible that under the dictatorship and after the deification of Julius Caesar the Roman republic fell, when it had been structurally sound for four centuries before? When the republic was established around the end of the 6th century B.C.E., the Romans made clear that they wished to avoid all semblance of the monarchy that had ruled for two centuries before. (T.J. Cornell, The Beginnings of Rome: Italy and Rome from the Bronze Age to the Punic Wars (c. 1000-264 BC), London and New York: Routledge, 1995; p. 215) The rule of the Republic was to be split into powers of the senate and consuls, a system that worked for over four centuries. The republic would face problems with the rise of the first triumvirate in 60 B.C.E., involving Julius Caesar, Crassus and Pompey. The triumvirate gained power that was intended to be in the hands of the senate and Roman assembly. This paved way to a situation in which a single man could sweep up the political power that previously belonged to the entire senate. Julius Caesar would use this tactic, following his campaigns of Gaul and Britton, to take sole dictatorship over Rome. While there were previous cases which individuals had been appointed as dictator, usually by the senate to serve for six months in a time of war, Caesar was appointed dictator three separate times.. After declining his first dictatorship, Caesar was awarded two more reigns as dictator for one and ten years, respectively. At this point Caesar was praised by the Roman people for his various military victories and had been awarded several awards and honors by the senate. Having conquered much of the surrounding territories, spanning from northern Africa to Greece, and enacting several reforms, Caesar was in the pro...

  • Neuropsychology & Spouse/Family Members

    I intend to explore the effects of a parietal brain injury from the perspective of a neuropsychologist; ranging from types of tests that are employed when trying to determine the extent of the damage, to gaining an understanding of how this damage will affect the rest of the brain and/or the body. I will also explore the effects of a brain injury from the perspective of the family members, and their experiences with the changes that occur during the rehabilitation process. According to The Neuropsychology Center, “neuropsychological assessment is a systematic clinical diagnostic procedure used to determine the extent of any possible behavioral deficits following diagnosed or suspected brain injury”(www.neuropsych.com). As mentioned previously, a brain injury can be the result of many types of injuries or disorders, thus a broad range of assessment procedures have been developed to encompass these possibilities.

  • The Effects of Concussions on Human Beings

    1295 Words  | 3 Pages

    Did you know, that someone suffers from a brain injury every 21 seconds (Haas)? Children get concussions all the time, and most of the time they go unnoticed. The majority of concussions happen when one is playing a sport such as football, hockey, or lacrosse. Many famous athletes have had their careers, even their lives cut short due to concussions. Brain damage and death can result from serial concussions (Schafer). When one suffers from a concussion, one’s brain needs time to recover physically and mentally. Between 2002 and 2006, statistics showed that 52,000 people died from concussions and about 275,000 were hospitalized (Fundukian). Everyone’s recovery process is different (“Injury and Pain Care”). Although concussions seem minor, they are very serious brain injuries that may result in severe damage to one’s brain.

  • What´s Chronic Traumatic Encephalopathy (CTE)?

    Chronic Traumatic Encephalopathy, previously referred to as dementia pugilistica, can be understood as a tauopathic, neurodegenerative and neuropsychiatric disease. While there is no neurobiological or neuropathological explanation as to why CTE occurs, the majority of researchers believe the disease is strongly related to previous head injuries. An individual suffering from CTE will most likely experience changes in their mood, behavior and cognition. Because this is a relatively new area of research, there are still a vast amount of unknowns pertaining to the disease’s symptoms, pathology, and natural course.

  • Exploring the Intricate Link Between Memory and the Brain

    Therefore, they summarize that the reason why Clive suffers in the Amnesia is caused by the hippocampus is not affected. The Hippocampus is a structure that is located inside the temporal lobe, and that is a part of the limbic system. The function of the Hippocampus is similar to a post office used for encoding, storage and recalling memories, all presenting information would first remain, analysed and encoded in the Hippocampus then transmit them to different areas of the brain. In other words, Clive is unable to encode memory and hold information which is currently aware, and it is difficult to form new long-term memory such as explicit and semantic memory. Clive Wearing, now 78 years old, still cannot recover from the anterograde amnesia, he becomes a man who has the shortest memory in the world.

    ...istory through the use of a popular topic amongst modern readers. Strauss does often times go far too deep describing the landscape, using names of Italian cities and natural landmarks rather in depth, which loses a reader not wholly familiar with Italy’s landscape. Strauss also quite openly marvels at the figure of Spartacus himself, which could be a bias on the part of the researcher that some readers might call into question. Also, Strauss makes some definitive statements regarding why events happened, yet due to the nature of small samples of evidence, Strauss is mainly just making inductive guesswork, although usually logical guesswork. Overall though, Strauss effectively tells a lively story that enriches the reader’s knowledge on Roman history in an entertaining way.

  • Lucius Cornelius Sulla And The Republic

    1672 Words  | 4 Pages

    In final analysis, Sulla’s actions as a politician and a military leader, while occasionally bringing him prestige - dignatas, were major factors leading to the subsequent weakening of the Republic. Sulla was an odd mixture of cynicism and superstition, public sobriety and private indulgence. His reforms achieved very little besides adding to the sum of human misery. He brought an unprecedented ruthlessness to Roman life; and, though it may be conceded that his political intentions were good, his contemptible methods , notably marching his own Roman army upon the capital, contributed more than those of any other man to the debasement of the Republican constitution, he avowedly restored.

    The first of many problems was the collapse of the Triumvirate. The Triumvirate was one of the main parts of the government of Rome, with which there were three leaders, which at the time were Caesar, Pompey, and Crassus. This was never truly working all that great, but held itself together by the marriage of Caesar's daughter Julia, to Pompey, and the friendship Caesar and Crassus shared. But, all this came to an end when Crassus was killed in a battle against a Parthian army. Then, not too long afterwards, Julia was murdered by someone who had broken into her home. This, destroyed the bond between Caesar and Pompey, and made them drift apart. Caesar seeing all this taking place, attempted to restore the bond by proposing to Pompey's only daughter, but was not allowed to by Pompey.

    Like the Greek Theogony, the creation of the world in the Enuma Elish begins with the universe in a formless state, from which the primary gods emerge. In the Enuma Elish, “[w]hen the skies above were not yet named [n]or earth below pronounced by name, Apsu, the first one, their begetter, [a]nd maker Tiamat, who bore them all,… mixed their waters together…[t]hen gods were born within them.” Apsu, which represents fresh water, and Tiamat, who represents salt water and is later referred to as “earth mother,” are both born from the primordial waters and are the first rulers of the gods. In the Theogony, it is stated that “at first Chaos came to be,” implying that at some point in time he did not exist. In the ancient near east, the primordial waters were waters that existed at the beginning of, or even before, creation that were associated with serpents and chaos. Hence, even though chaos in Greek means “chams” or “empty space,” the primordial god Chaos can be equated with the primordial waters. “Next wide-bossomed Earth (Gaia) [came to be]…and dim Tartarus…and Eros...And Earth first bare starry Heaven…” As we can see, while both myths begin with the primordial deities, the Theogony ...
