A Study On Traumatic Brain Injury

The pathophysiology of traumatic brain injuries can be slightly different depending on the type of injury that has occurred. For example, injuries can result from

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

A traumatic brain injury (“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 influences how a patient with TBI is treated by medical staff and rehabilitation specialists. TBIs can affect a specific part of the brain that was directly impacted, leaving the patients with only one or a few areas of impairment, or the damage can

The brain is vulnerable, and is susceptible to mild traumatic brain injuries (mTBIs). A person’s head jerks forward and back; this rapid change in acceleration causes a concussion because of impact. Examples of impact injuries that frequently occur in athletics are collisions, falls, and bumps to the head. Regardless of how a person sustains a concussion, her brain collides with ridges in her skull. Although the purpose of a skull is to protect the brain; the fusion of bones in a person’s skull creates ridges, and these ridges damage the brain upon impact. When a person’s brain is shaken up, the sharp ridges damage the prefrontal cortex and temporal lobes (Hirsch & Kaufman, 1975).

For a long time, traumatic brain injury has been a large contributor to disabilities and death within the United States. Around 30 percent of these injuries lead to death, and those who survive these injuries may suffer from short-term side effects to long-term disabilities. It can range from a minor head injury to a major injury that you might suffer from a motorcycle accident.

Concussion or mild traumatic brain injury (mTBI) represents the most common type of traumatic brain injury (TBI). Even though this type of TBI is called “mild”, the effect on the family and the injured person can be devastating. Concussions can be tricky to diagnose and there is no specific cure for concussion. There is growing recognition and some evidence that mild mechanical trauma resulting from sports injuries, military combat, and other physically engaging pursuits may have cumulative and chronic neurological consequences [3, 4]. However there is still a poor understanding of concussions and their effects. Studying mild brain injury in humans is challenging since it is restricted to cognitive assessment and brain imaging evaluation. Animal models provide a means to study concussions in a rigorous, controlled, and efficient manner with the hope of further diagnosis and treatment of mTBI.

The review study written by Barkhoudarian et al explored the pathophysiology of concussive brain injury in young athletes. Sport-related concussions cause diffuse axonal injury (DAI) or white matter shearing injury (Barkhoudarian et al., 2011; Wozniak et al., 2007). They disrupt the axonal membrane leading to a disrupted normal ionic crossing and increased calcium influx. This flow of calcium not only causes mitochondrial-swelling leading to possible apoptosis but also prevents microtubular function (Halstead et al., 2010; Barkhoudarian et al., 2011). All these factors together can prevent axonal transport and form axonal blebs (Figure 6), hence altering the

Traumatic brain injury (TBI) is a worldwide health problem that can lead to death or long-term disability even in people with mild TBI, especially in young population (Menon et al., 2010). More than 1.3 million visits to emergency department in the United States report for TBI (Faul et al., 2010). TBI can lead to sundry impairments and disabilities in physical , functional, cognitive, emotional and social realms which remarkably reduce health-related quality of life(HRQL) (Scholten et al., 2015: Andelic et al., 2009). TBI can be classified according to it severity into mild-moderate and sever TBI. Mild TBI (MTBI) also termed concussion score for over 77% of the entire reported TBI cases in the United States. About 40% of these cases are frequently

A diffuse axonal injury does not occur due to a blow to the head; it is caused by the brain moving back and forth within the skull. Vehicle crashes, falls, child abuse (shaken baby syndrome), sports-related accidents and violence are all common causes of this kind of brain injury. This type of injury

Mild traumatic brain injury (mTBI) has gained considerable notice in recent years since the Global War on Terrorism. High percentages of service members surviving combat-related injuries are now battling the long-lasting effects and associated medical morbidities of brain trauma. Nearly 1.6 million service members deployed in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) through June 30, 2007 (Defense Manpower Data Center ). While percentages of those deployed sustaining mTBI are only approximations and may underestimate prevalence of injury and underscore the subsequent impact of postconcussive symptoms, as many as 12-35% of those with exposure to combat are estimated to have experienced an mTBI (Schneiderman, Braver, & Kang, 2008 ; Hoge, et al., 2008 ). Moreover, an estimated 25,000 military personnel sustained an mTBI in 2014 alone, as reported by the Defense and Veterans Brain Injury Center (DVBIC, 2015). MTBI has a

The brain is a complex and curious organ; despite extensive research, scientists still know little about it. William Allman described the brain as “a monstrous, beautiful mess.” He went on to say that “its billions of nerve cells – called neurons – lie in a tangled web that display cognitive powers far exceeding any of the silicon machines [scientists] have built to mimic it” (faculty.washington.edu). Imagine this mess of neurons experiencing a simple disruption, one that creates a domino effect that effortlessly damages this intricately created organ. Some of the most disastrous disruptions to this complex organ, traumatic brain injuries, most commonly occur in the frontal lobe. Injuries to

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,
