A Study On Traumatic Brain Injury - 6528 Words

parindent{ }Traumatic brain injury is a significant health problem in the United States that is estimated to occur in 1.6-1.8 million persons annually (citealt{faul2010}). Diffuse axonal injury is a common type of traumatic brain injury primarily characterized by damage to the axons (citealt{smith2000, Gennarelli1982}). An enhanced knowledge of the pathophysiology of diffuse axonal injury is required to develop improved diagnostic tools, protective measures and rehabilitation treatments(citealt{Giordano2014}). Many techniques have been developed to help elucidate the injury mechanism associated with diffuse axonal injury over the years. Diffusion tensor imaging (DTI) is one such technique where the mesoscale structural information is studied to investigate the diffuse axonal injury. Finite element models have also provided a means to investigate diffuse axonal injury. Several finite element head models have been developed and reported in the literature (citealt{shugar1977,ward1980,hosey1982,Ruan1991,mendis1992,bandak1995,kang1997,al1999,Zhang2001,Kleiven2002,brands2002,takhounts2003,horgan2005,Kleiven2007,iwamoto2007,takhounts2008,panzer2012,mao2013,tse2014,cotton2015}). These models have demonstrated that over time, the structural resolution of the head models, including advancements in constitutive laws, anatomical resolution, and injury descriptions were improved.

While working at a railroad site, an iron tamping rod (43 inches long, 1.25 diameter) went through his left cheek, through his brain, and out the skull. He surprisingly ended up surviving this traumatic injury. After a month in the hospital, he was back out on the street. Once a nice, caring person, Phineas t urned into an aggressive man who could not even keep a job. Just like Phineas Gage, a TBI can potentially change everything.

This type of wound can result from a bump, blow, or jolt to the cranium. It may even result from the penetration of a foreign object into the brain tissue. Most TBI’s result from car accidents, sports injuries, blunt trauma, unintentional injuries and falls, with falls accountingRead MoreThe Effect Of Calcium On The Contribution Of Calcium Uptake Of The Vesicular Glutamate Released Into The Extracellular Space855 Words   |  4 Pagesanimals with traumatic brain injuries had significantly higher levels of extracellular glutamate evidenced by a nearly 80% increase when compared to the healthy mice (Hinzman et. Al., 2012). This showed that calcium mediated neuronal glutamate release may contribute to the cytotoxicity experienced by patients affected by traumatic brain injury. The second part of the study examined the importance of excitatory amino acid transporters in patients suffering from traumatic brain injury. To accomplishRead MoreTraumatic Brain Syndrome in Veterans1070 Words   |  4 PagesIssue: Traumatic Brain syndrome in veterans Introduction: Soldiers returning from combat face a wide range of challenges in adjusting to civilian life. These challenges are compounded by the high susceptibility of combat-experienced soldiers to Post Traumatic Stress Disorder (PTSD) and overlapping symptoms of traumatic brain syndrome. As the two articles considered hereafter demonstrate, the U.S. military has sought better ways of understanding the primary symptoms and health consequences of traumaticRead MoreSymptoms And Symptoms Of A Concussion1312 Words   |  6 Pageslong-term brain damage and cognitive impairment later in life. A concussion is a subset of a Traumatic Brain Injury (TBI) and results from shaking the brain within the skull. The American Association of Neurological Surgeons (the â€Å"AANS†) has defined a concussion as â€Å"a clinical syndrome characterized by an immediate and transient alteration in brain function, including an alteration of mental status and level of consciousness, resulting from mechanical for ce or trauma.† (Sports-related Head Injury) TheRead MoreRecovery Time After Concussion Essay855 Words   |  4 PagesResearch Question: Can blood test predict recovery time after concussion? Abstract Background: There is currently no objective testing markers to predict recovery time after an athlete suffers a concussion. Recent studies are aimed to determine whether or not biomarkers in the blood will be able to help in identifying recovery time after a concussion. Purpose: To determine whether or not protein biomarkers in the blood can serve to predict adequate recovery time after a concussion. Results:Read MoreA Traumatic Brain Injury 1708 Words   |  7 PagesA traumatic brain injury (â€Å"TBI†) occurs when the brain is somehow injured, rattled, or wounded from an external source of force. The means of acquisition and the severity of TBIs are unique to each patient; therefore, symptoms and rehabilitation can vary greatly depending on the patient’s condition following the incident and how they sustained the injury. The severity of a TBI is generally classified into one of three categories: mild, moderate, or severe, and this type of diagnostic criteria influencesRead MoreSelf Reported Pain And Pain Management Strategies Among Veterans With Traumatic Brain Injury1593 Words   |  7 Pages The authors of the pilot study all have remarkable educational backgrounds. To begin, with, I discovered P.R.King, G.P. Beehler, and M.J.Wade all had limited amount of experience due to only writing one or two articles that were published, but King Beeler, and Wade all ha ve PHD’s. The article was clearly identified as a quantative study by the authors using a pilot study. The variables of the study are the self-reported pain and pain management strategies.
