Essay On Traumatic Brain Injury

Improved Essays
Throughout human history, especially military history, the brain has been known to be a crucial part of the body needing protection from projectiles and blunt force impact. The average human head weighs approximately 10 pounds and is perched dangerously exposed on the vulnerable neck of the body. Encased in a relatively thin shell of bone, the brain floats in a fluid designed to further cushion and protect this vital organ. When those protective measures fail and the head is struck or violently jarred, the brain is likely to suffer injury. This type of injury is now known as Traumatic Brain Injury or TBI. The causes of Traumatic Brain Injury and the effects vary by person, the cause and extent of the injury as well as the area of the brain affected. Manley states that Traumatic Brain Injury (TBI) is a multifaceted condition, not an event (473). TBI is generally the result of a sudden, violent impact or jolt to the head due to falls, vehicle accidents and violence. TBI may also be caused by such objects as bullets or a shattered piece of the skull penetrating the brain. During impacts or severe jolts, the fluid fails to adequately cushion the brain and the brain is launched into a …show more content…
Additional physical symptoms for moderate cases may include: loss of consciousness for minutes to hours, convulsions or seizures, there may be dilation of one or both eyes, clear fluid draining from the nose or ears, weakness or numbness in fingers and toes as well as a loss of coordination. Additional cognitive and mental symptoms for moderate cases of TBI can include: profound confusion, agitation, combativeness or unusual behavior, slurred speech, coma or disorders of consciousness. The symptoms of severe cases of TBI resemble moderate symptoms, but are more extreme and may also include unconsciousness lasting for days, amnesia, disability, and even death. (Valente

    It occurs when an athlete suffers repeated concussions without adequate time to heal in between concussions. The pro- posed mechanism of SIS is that following the initial concussion, the brain is in a vulnerable state and when concussed again, due to impaired cerebral auto regulation, massive cerebral edema and herniation of the brain through the bottom of the skull occurs causing death. (Bodle, 2014) The medium-term effects of concussion also constitute a variety of neurologic and cognitive deficits. These symptoms of the “post-concussive syndrome” include persistent headache, light-headedness, lethargy, sleep disturbance, photophobia, phonophobia, memory dysfunction, poor attention and concentration as well as anxiety, irritability, and depression.

    A rough blow to the head, neck, or upper body can make the brain move around powerfully against the inner walls of the skull. The frontal and temporal lobes are the common parts of the brain that are affected by a concussion because those lobes are the closest to a rather rigid bone. When the head rotates the front of the head moves a greater distance due to the fact that the neck is positioned posteriorly to the skull. Dr. Kelly states in his interview that the frontal lobe influences personality, planning, initiating, and organizing, whereas the temporal lobe is primarily the language functions and memory. The memory in the left hemisphere is the verbal memory while the right hemisphere is the non-verbal visual memory.…

    Medication, occasionally counting surgery, is required if the fissure creates complications. Temporal bone fractures induce numerous damages to the internal ear. Damages encompass burst of the eardrum and injury to the ossicles, the cochlea, the vestibular apparatus, or the nerve that regulate muscles of the visage. Occasionally, serous fluid taken away from the brain and spinal cord (cerebrospinal fluid) flows from the brain into the fracture and emerge as unclouded fluent depleting from the ear or nose. That flowing proves that the brain is unprotected to severe virus from microbes within the ear canal.…

    A concussion is an injury to the brain. It can be caused by a blow to the head, or any movement that shakes the brain inside the skull. The brain is a soft organ surrounded by spinal fluid and protected by a hard skull. Normally the fluid acts like a cushion for the brain, but if the blow is hard enough, the brain can crash into the skull and be damaged. Some common symptoms that you could experience after having a concussion would be headaches, blurred vision, and sensitivity to light and noise.…
