Evaluating the Limitations of Post-traumatic Amnesia as a Severity Scale Traumatic brain injuries (TBI) account to a third (30.5%) of all injury-related deaths in the U.S. with an estimated 1.7 million individuals sustaining TBI each year (Center for Disease Control and Prevention, 2010). Classifications of brain injury (e.g., mild, moderate and severe) is mostly done using the Glasgow coma scale (GCS) which has gained broad acceptance for the assessment of the severity of brain damage (Bauer & Fritz, 2004). Recent studies suggest that almost all patients with moderate or severe TBI have a period of recovery during which they are responsive but confused. This state is commonly referred to as the post-traumatic amnesia. Post-traumatic …show more content…
In addition, they also assess the magnitude of the brain injury through magnetic resonance imaging (MRI; Wilson et al., 1993). The data in this study support earlier research connoting that patients have short coma but report prolonged PTA. They found that patients showed substantially more extensive hemispheric damage when patients with perpetuated PTA (>7 days) and short coma (<6 hours) when compared in the acute stage of MRI. Researchers conclude that although both coma and PTA are related to brain damage they still reflect disparate patterns of lesions. Thus, PTA assessment remains as a valuable measure by providing additional information concerning the severity of injury (Wilson et al., 1993). The duration of PTA is retrospectively measured by most studies at interview by catechizing the patient about their memories around the time of injury (Greenwood, 1997). Critics pose significant concerns regarding the retrospective method due to the lack of standardized protocol, undocumented prospective measurement of episodic memory, and questionable reliability issues (McMillan, Jongen, & Greenwood, 1996; Tate et al., 2000). One of the issues is that clinicians often rely on the patient’s own judgment and the relatives’ memory for events. Many find this problematic due to the potential contingency of confabulations right after traumatic injury (McMillan et al., 2012). In addition, concerns were
How is memory encoded and what methods can lead to greater recall? There have been many different models suggested for human memory and many different attempts at defining a specific method of encoding that will lead to greater recall. In this experiment subjects are asked to do a semantic task on a word related to them and an orthographic task in which they analyze the letter in the word. The results of the experiment indicate that the words which where encoded semantically and are related to the self have greater recall.
Awareness about traumatic brain injury has increased because of combat operations in Irag and Afghanistan and in the National Football League. The debate over the nature of traumatic brain injury is an ongoing issue. Some think of categorizing from mild to the server is the condition of TBI that can lead to a person bring over diagnosed or misdiagnosed. The other side points out that the focus should not be on diagnosis put on the recovery and treatment of the symptoms.
Traumatic brain injury (TBI) is a type of injury that is a critical public health and socio-economic problem. TBI is a leading cause of death and disability in both children and adults [5]. The Centers for Disease Control and
The Glasgow coma scale is the scoring system that monitors and assesses the level of consciousness of a patient that has had a traumatic injury e.g. brain injury, car accident or sports injury (Braine & cook, 2016). The Glasgow coma scale is a score between 3-15 with 3 being the worst and 15 being the best. This scale is composed of 3 sections which are the best eye response this assessment is important to assess the arousal of the patient which reflexes the integrity of reticular activating system of the brain which assesses by 1. No eye opening 2. Opens to pain 3. Opens to voice 4. Opens spontaneously, the best verbal response this assessment reflects the integrity of higher cognitive and interpretive centres of the brain. The verbal response depends on the language centre in the temporal lobe and in the frontal lobe which assess 1. No verbal response 2. Incomprehensive sounds 3. Inappropriate words 4. Confused 5. Orientated and best motor response this assessment check the function ability of the cerebral cortex, the patient has to understand the commands and perform the movement accordingly, they assess the upper extremities by simple orders because they are more reliable than the lower extremities this is assessed by 1. No motor response 2. Extension to pain 3. Flexion to pain 4. Withdrawals from pain 5. Localising pain 6. Obeys commands, these are the three sections that nurses needs to access (Elliot, Aitken & Chaboyer,
The application of scientific knowledge to understanding the impact of concussions on mental health is critical for providing appropriate clinical diagnosis and treatment. Concussions vary in severity and can have debilitating effects that result in post-concussion syndrome. Having had personal experiences with brain injury, I know how difficult it is to witness deterioration of mental abilities and to cope with the stress of healing. I have always been interested in studying the complexities of the brain; however, my experience has only substantially increased my interest. My primary interest lies within the field of neuroscience, in which I would like to explore the effects of post-concussion symptoms on underlying mental health challenges and linguistic performance.
Medical and technological advances have led to greater survival rates in individuals suffering from various illness and injury throughout history. This includes individuals who suffer traumatic and nontraumatic brain injuries. Approximately 1.5 million people in the United States sustain a brain injury each year with the survival rate of over 90 percent making brain injury the leading cause for disability in the United States. (Mysiw, Bogner, Corrigan, Fugate, Clinchot, & Kadyan 2006). Cognitive, physical, sensory and behavioral changes are widely noted in individuals in the months and years following a brain injury. However, the psychosocial, psychological and emotional effects of these injuries are less discussed and therefore these aspects can be overlooked when anticipating a course of treatment. Individuals who sustain acquired brain injuries experience significant, lasting impairment in the psychosocial, psychological and emotional aspects of their lives and better understanding of these issues can lead to better treatment and coping skills for these individuals.
At least 50% of all adults and children are exposed to a psychologically traumatic event (such as a life-threatening assault or accident, humanmade or natural disaster, or war). As many as 67% of trauma survivors experience lasting psychosocial impairment, including post-traumatic stress disorder (PTSD); panic, phobic, or generalized anxiety disorders; depression; or substance abuse.(Van der Kolk, et al, 1994) Symptoms of PTSD include persistent involuntary re-experiencing of traumatic distress, emotional numbing and detachment from other people, and hyperarousal (irritability, insomnia, fearfulness, nervous agitation). PTSD is linked to structural neurochemical changes in the central nervous system which may have a direct
Traumatic brain injury (TBI) has affected many people, but has hardly raised awareness; in fact according to Marcia Clemmitt “About 1.7 million Americans suffer a traumatic brain injury (TBI) every year…Yet, while they affect so many people, TBI has received little medical-research funding until brain injuries from the wars in Iraq and Afghanistan … began to mount in recent years.”(Clemmitt) For such a long time many people were unaware of what traumatic brain injury even meant; Up until a numerous groups of veterans that came back home, from Afghanistan were found to suffer from traumatic brain injuries. Due to the discovery, the people that already suffered from traumatic brain injury
Further biological research on the effect of psychological trauma on the neurochemistry of memory may help clinicians distinguish between true repressed memories and false memories in clients who report abuse. However, to date there is no method to determine the accuracy of these memories. Therefore clinicians and the
Annotated Bibliography: The article starts by defining what Type I and Type II mean in regards to traumas. Type I is when a person undergoes trauma in one specific event, however Type II is when a person goes through a long-term trauma with an unvaried amount of time. It also discusses the survival brain versus the learning brain, where the person has a survival brain is constantly surveying their environment scanning
Traumatic brain injury (TBI), or intracranial injury, is a medical diagnosis which refers to closed or penetrative damage to the brain that is caused by an external source. Every year, TBIs affect approximately 150-250 people in a population of 100,000 (León-Carrión, Domínguez-Morales, Martín, & Murillo-Cabezas, 2005). The leading causes of TBI are traffic accidents, work injuries, sports injuries, and extreme violence (León-Carrión et al., 2005). TBI is most often fatal when the cause is an injury due to the use of firearms, a traffic accident, or a long fall (León-Carrión et al., 2005). However, fatality rates and rates of occurrence differ in various countries due to
Traumatic Brain Injury is otherwise known as TBI. “Traumatic brain injury, a form of acquired brain injury, occurs when sudden trauma causes damage to the brain. TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue” (NINDS, 2010). There are two main types of TBI, closed head injuries such as head hitting a windshield and penetrating head injuries such as a gunshot wound. As reported by the Global Neuroscience Initiative Foundation,” The severity of traumatic brain injuries is often assessed using the Glasgow Coma Scale, with scores ranging from 3 to 15. The higher the score,
If we had an option to wipe out our memory, would we choose to forget about the events that involved actual or threatened death, serious injury, or a threat to the physical integrity of ourselves or others? For soldiers, it may be losing a close comrade in a war. For me or any other ordinary individuals, they may be natural or human-made disasters, violent personal attack, torture or even sexually abuse(Parekh). The truth is, we don’t want to be reminded of any of these terrible events that took away a small portion of our lives.
The Possible Effects of Post Traumatic Stress Post traumatic stress disorder is an anxiety disorder associated with serious traumatic events and characterized by such symptoms as survivor guilt, reliving the trauma in dreams, numbness and lack of involvement with reality, or recurrent thoughts and images. Post Traumatic Stress Disorder (PTSD) can develop at any age, including in childhood. Symptoms typically begin within 3 months of a traumatic event, although occasionally they do not begin until years later. Once PTSD occurs, the severity and duration of the illness varies. Some people recover within 6 months, while others suffer much longer.
A fundamental aspect of human memory is that the more time elapsed since an event, the fainter the memory becomes. This has been shown to be true on a relatively linear scale with the exception of our first three to four years of life (Fitzgerald, 1991). It is even common for adults not to have any memory before the age of six or seven. The absence of memory in these first years has sparked much interest as to how and why it happens. Ever since Freud (1916/1963) first popularized the phenomenon there have been many questions and few robust empirical studies. Childhood amnesia is defined as the period of life from which no events are remembered (Usher & Neisser, 1993) beginning at birth and ending at the onset of your
