General Overview of CTE: Chronic Traumatic Encephalopathy (CTE), a condition characterized by progressive neurodegeneration of the brain, was first diagnosed by Dr. Bennet Omalu in 2002. CTE affects those who have suffered multiple and repeated brain injuries, such as athletes of high contact sports and veterans of war and is only able to be diagnosed post-mortem. For example, much research has been centered on athletes that play football in the NFL. It is reported that over 90% of players who play at the professional level have some degree of this disease, regardless of the position played (Gregory, 2015). The reason that football players and athletes involved in high contact sports develop CTE is because of the high frequency of head injuries that they are subjected to. The brain does not have any sort of safety belt protecting it from being damaged, so it is very prone to injury. There are various degrees of brain injuries that contribute to the development of CTE such as rTBI, and blast exposure, and the temporal and frontal lobes are regions of the brain that are known to trigger CTE (McKee et al., 2013). Another factor that may contribute to the development of CTE is immunoexcitotoxicity, which is the reaction that occurs when neurons are exposed to excess glutamate. Immunoexcitotoxicity triggers degeneration in the areas of the brain that receive the most damage as a result of an injury (Baylock & Marron, 2011). This change in the brain’s chemistry and structure…
