-1 Mike Craveiro Concussions “More than one million Americans suffer head injuries each year that are serious enough to send them to hospitals” (Harvard, 2007, p.1). An impressive majority of these are concussions. Concussions or Mild Traumatic Brain Injuries (mTBI) are defined as a transient trauma-induced impairment of mental status, with or without the loss of consciousness. Approximately 300,000 sport-related traumatic brain injuries occur per year, and that is just sports alone. When a concussion occurs all the cells in the brain fire at the same time. This causes a flood of neurotransmitters in the brain. The excess neurotransmitters cause potassium ions to flow out of the cells and calcium ions to flow in. To reverse this process the brain requires an extra amount of energy. Be that as it may, the buildup of calcium within the cells causes the brain to be less efficient at processing energy. Due to the low amount of energy in the brain, a significant portion of the brain cells go quiet, causing the brain to function improperly. Currently the only treatment for a concussion is time. Concussions are one of the most common, yet untreatable injuries in the world. (Weir, 2007) Although sports-related incidents are the most recognized causes of concussions, there are many other ways to contract them. “Traumatic brain injury is an important source of morbidity in the Iraq and Afghanistan Wars” (Warden, 2006, p.398). There have been more than 1700 cases of mild traumatic brain injury since the war’s start. In most cases immediate symptoms occur instantaneously. Some examples of these are a vacant stare, loss of consciousness, slow speech, and memory loss. These symptoms should not be used to determine the severity of the concussion because some individuals
