Causes Of Diffuse Axonal Injuries

Decent Essays
Diffuse axonal injuries are often described as a form of nerve damage that occurs when there is a reduction to the long nerve fibers, or axons, of the brain. Tearing occurs when an injury to the head is significant enough to cause the brain to shift or rotate within the skull itself. This causes significant injury since the brain begins to swell as a result of the injury, while also causing brain cells to become broken (Brain Injury Institute, 2011). As a result, the neurons in the brain begin to lose their ability to communicate effectively with one another, which disrupts the activation of important neural operations, including those related to motor, speech, and other forms of essential physiological functioning (Brain Injury Institute,

    He worked as a lawyer, he was very organized, took care of paying the bills, and enjoyed things such as Japanese cinema and highbrow conversations. However, when Alan awoke from his several week long coma, he was toddler-like in cognitive and psychological ability, as well as the entire right side of his body being paralyzed. His official diagnosis was diffused axonal injury (DAI) with subdural hematomas on his frontal lobes. Imajo, T. and Roessman, U. (1984) broadly define DAI as a distinct form of head injury induced by direct external force at the time of trauma and characterized by axonal swelling, hemorrhages or lacerations of the corpus callosum, and of the brain stem. Basically, the axons in the brain, which are key in sending and receiving signals, had been severely sheared off during the accident.…

    The rotational movements of the brain inside the skull and the shearing forces affecting the upper reticular formation that create torque, which leads to the typical loss of consciousness. These forces also cause the brain to move in a swirling fashion and contact the inner prominence of the skull, particularly the petrous and orbital ridges and the wings of the sphenoid. Such movement makes the brain bump into the interior of the skull at the point of impact, as well as on the opposite side of the skull, resulting in bruises that damage the…

    When it comes to designing a helmet, physics plays an important role. Newton’s second law of motion demonstrates the relationship between force, mass, and acceleration, explaining that the force is equal to the mass of an object times the acceleration. If we apply this rule to football, it can be concluded that although the mass (of the football player) is unlikely to be changed, the acceleration can be. The new Zero1 helmet was specifically designed to address the acceleration a player experiences during impact in order to reduce these sheering forces (VICIS, 2016). Even though this helmet is brand new, the Zero1 has been tested in many supervised and controlled settings using players from the NFL, the National Collegiate Athletic Association…

    Like a muscle, your brain can also be injured. Unlike bruises, breaks, or sprains, you cannot simply apply a cast, brace, or bandage to help heal them. The brain has a very different way of healing itself. Since the brain is your main control room of your body, it takes time and patience to heal depending on the…

    When they are not fatal, then they usually cause a person to lose behavioral or sensory functions. These function loss is in the parts controlled by the area of the brain that is injured. The other type of brain injury is called a closed brain injury. This occurs when the head is hit so hard that it makes the brain hit the side of the skull. Because of so much force when the brain hits the skull, it breaks connections between parts of the brain.…

I was not shot, was not in a wreck, but I merely whiplashed my head on a turf football field after jumping up to catch a football. As soon as my head hit the ground, I was instantly knocked unconscious. My body was convulsing uncontrollably. I was choking on my tongue and my mouth was foaming with blood.…

    Traumatic Brain Injuries in athletes and CTE, Chapter 2 Brain injuries can be as mild as a concussion, and as severe as a traumatic brain injury, or TBI. A traumatic brain injury is diagnosed when a person’s normal brain function has been negatively altered after receiving a forceful trauma to the head (Hockenbury, Nolan & Hockenbury, 2015). Although it is not something we often think about, our brains are highly vulnerable to injury (Hockenbury, Nolan & Hockenbury, 2015). Fortunately most people are able to fully recover after obtaining a concussion, but individuals who experience a lifetime of concussions are more apt to develop Chronic Traumatic Encephalopathy or CTE.…

    The modern world is known for its advances in the field of medical sciences as well as in medical developments in general. Such developments have led to the increasing inquiries of contusions and concussions. Although contusions and concussions are easily confounded, their discrepancies illustrate their distinctiveness and alterations. Contusions and concussions are often perplexed by virtue of similar causes; both transpire as a result of a fall or strike to the head, inducing a traumatic brain injury (or TBI). However, the effects of the brain trauma bring about its classification.…

    Introduction Approximately 1.7 million people acquire a traumatic brain injury in the United States every year, impacting millions of people’s daily lives (Powell, Rich, & Wise, 2016). A traumatic brain injury (TBI) occurs when an external or internal force impacts the brain, which causes physical and chemical alterations in the brain. In recent years, rates of TBI have increased dramatically; however, more people are receiving treatment after a TBI, so mortality rates are decreasing (“Rates of TBI-related emergency department visits, hospitalizations, and deaths,” 2016). According to Andriessen et al. (2011), the leading cause of a TBI is motor vehicle accidents, followed by falls, assaults, and sports.…
