Introduction Chronic traumatic encephalopathy (CTE) is the current understanding of a form of progressive dementia that used to be classified as punch drunk syndrome in boxers as early as the 1920s all the way up until the 1950s and 1960s 6. What makes this disease so elusive is its difficulty to be detected until postmortem autopsies are conducted 6. As a consequence, several professional athletes experiencing head injuries were unaware of the fatal consequences of participating in sports involving major blows to the head like boxing, hockey, and second most notoriously, American football 3,6. In fact, clinicians have noted a positive correlation between time spent playing football and pathological CTE in the postmortem analysis of brain tissue in ex-football players 2. Other causes of traumatic brain injury (TBI) that could lead to CTE through events unrelated to sports include assault, vehicular mishaps, and even domestic violence 1.
Active areas of research include identifying the origin(s) of pathology for CTE 3, imaging techniques to find microstructural changes in the brain that can give indication to progression of the disease 6, utilizing tau immunohistochemistry to identify possible protein deformations contributing to the disease 1, and identifying the variability associated with the progression of the disease 4.
Pathogenesis and Pathophysiology of CTE
The origin of the pathophysiology of CTE can be quite complex, so other forms of traumatic brain injury have
CTE is a brain disease found in individuals with annals of head trauma. It has specifically been found in athletes with numerous concussions. So far it can only be diagnosed in the deceased, but Dr. Julian Bales and his staff in UCLA have discovered symptoms in living players such as Hall of Famer Anthony “Tony” Dorsett, Hall of Famer Joe DeLamielleure, and NFL All-Pro Leonard Marshall. CTE can cause memory loss, dementia, depression, suicidal thoughts, cognitive and emotional difficulties (Waldron par 1, 2, 3). Is it a compelling issue? A total of 171 concussions were reported in the NFL in the 2012-2013 season; 88 thus far in the 2013-2014 season (Frontline pt). Those are just numbers in the professional level. There are thousands of kids playing football either in youth, middle school, high school, or college level. The diagnosis is currently in progress, researchers are optimistic this could lead to a legitimate treatment, how to manage, and hopefully a cure. Furthermore, this can also possibly lead to an answer to a connection between football and chronic traumatic encephalopathy. Junior Seau, Mike Webster, Terry Long, and Justin Strzelczyk (all of whom are dead now) are all men who played in the NFL for an extent period of time. This is not the only thing they have in common. These former players had an uncustomary
While we have recently found a way to detect signs of CTE in living players, there is no way to confirm the presence of CTE other than in a postmortem
CTE basically make the cells spit out a protein that can spill out due to blunt force trauma this protein can disable neural pathways that controls things such as memory or judgement.
According to James Bukes of the Pittsburgh Post, “The physical manifestations of CTE are a reduction in brain weight with atrophy of the medial temporal lobe, the frontal and temporal cortices, the brainstem, cerebellum hippocampus and other parts of the brain” (Bukes). This reduction in brain weight and brain size is caused by repetitive hits to the head, which is most often found in sports such as boxing, hockey and most notably, American Football. Due to the reduction of brain size, CTE has become known as an extremely debilitating disease, as well as life threatening. In an article from the Northeastern University the symptoms of CTE have been stated as, “depression, anger, memory loss and suicide” (Polnerow). There have been several cases reported of football players committing suicide, and then later being found to have been afflicted by this disease, most notably Dave Duerson, who donated his brain to CTE research after having committed suicide. Even though CTE has been proven through repeated studies, the general public is still in conflict over the true dangers of CTE and even if CTE is a true disease. In one study, 90 brains that had been examined of football players postmortem, 86 of them had cases of CTE (Storin). This is nearly 96 percent of examined brains that were found to contain CTE, meanwhile only 10 percent of the public are reported
While examining his brain, they found the first case of CTE (Chronic Traumatic Encephalopathy) in a football player (Ezell). Dr. Omalu continued into the brains of football players. He diagnost another player with CTE. After that, two other doctors connect concussions to dementia. Dr. Bailes and Dr. Guskiewicz wrote, “that the onset of dementia-related syndromes may be initiated by repetitive cerebral concussions in professional football players” (Ezell). This was the first major finding connecting football to brain injuries.
Did you know that 99% of the dead NFL players had signs of Chronic traumatic encephalopathy (CTE) when scientist looked through their brain (Ventras)? Most people wouldn’t know this fact, but scientist do and have known this since 2002. Even though they are making improvements, there is still an alarming rate of concussions happening. This report will discuss who is affected, how it can be prevented, how it is affecting sports today.
A CTE, or Chronic Traumatic Encephalopathy, is a, “progressive degenerative disease that is believed to plague people who've suffered severe or repeated blows to the head” (Murphy). A player can have a CTE and not even know that they are suffering from it. This is because CTEs can only be discovered after the person dies. Paul Bright, for example, was a football player who played from the time that he was seven until he was a freshman in high school. He had experienced only one concussion, but it changed his entire life. His family and friends described him as hard working and upbeat, but then, something changed. He became reckless and erratic; these traits caused him to die at age twenty-four from a motorcycle wreck. His mother sent his brain off to be tested and discovered that he had been suffering from Chronic Traumatic Encephalopathy. This brain disease had caused him to make the type of impulsive decisions that took his life (Murphy). In addition to the CTEs players may experience, the likelihood of dying from brain and nervous system issues increases significantly for football players. Studies from the National Institute for Occupational Safety and Health discovered that, “death involving neurodegenerative causes among the retired players was three times higher than in the general U.S. population, and the risk for two major
Within the last few years, the BU ADC developed a new branch called the Chronic Traumatic Encephalopathy Center (CTE Center), which is devoted specifically to research this disease (Boston University, n.d.). In 2015, a team of scientists from the CTE Center conducted a study analyzing the brain tissue of deceased football players. The researchers separated the participants into two groups: (a) those who played professional football, and (b) those who had played football during some part of their lifetime (high school level, college level, etc.). The results showed that 87 of the 91 NFL players tested positive for CTE. In addition, 131 of the 195 subjects who had played football during some part of their lifetime tested positive for CTE (Breslow, 2015). This study proved that CTE could affect any athlete (including high school level athletes), not just professional
Since the 1920s, there has been a severe disease linked to athletes. Chronic Traumatic Encephalopathy (CTE) is a disease that effects athletes that have had head trauma. The trauma causes the brain tissue to deteriorate. The changes can become apparent after months, years, or even decades. CTE is linked to memory loss, confusion, impaired judgment, impulse control problems, aggression, depression, and, eventually, progressive dementia. (“What”, 2009). CTE has caused football to change as well as the equipment. CTE is now widely known and is effecting, not only professional athletes, but also high school athletes. Concussions and chronic traumatic encephalopathy are serious conditions that can affect anyone and have adverse effects.
Chronic Traumatic Encephalopathy, or better known as CTE has gained momentum in areas of public awareness and scientific involvement in recent years due to the popularized sport on American Football. During recent years, the media has been swaying and educating the public on the adverse outcomes that CTE can initiate. However, the first discovery of this disease was diagnosed by pathologist Harrison Martland and can be related back to the late 1920’s; the first true cases were identified in the physical sport of boxing. During that time, CTE was commonly known as dementia pugilistica meaning “punch drunk” from the wobbly nature of boxers during repetitive hits to the head.1,2 It was determined that dementia pugilistica (also known as boxer’s
Chronic Traumatic Encephalopathy also known as C.T.E is a degenerative brain disease found in athletes, military veterans, and others with repetitive brain trauma (Mayo Clinic Staff, 2017). The Editorial Board wrote the article “The Scars From ‘Bell Ringing” Football Tackles,” publish July 29, 2017 in the New York Times, the Board argues that C.T.E is linked to football with the research help of Dr. Ann McKee. The Board uses pathos and logos effectively but when it comes to ethos, they do not build up their credibility.
Over the past several years, concussions and Chronic Traumatic Encephalopathy (CTE) have become hot topics in the world of football. The long lasting effects of concussions and CTE experienced
The disease is caused by a build-up of an abnormal protein, named tau, which strangles brain cells. To this day, CTE has no known cure. However, it can be reversed, slowed down, or even stopped. Though there is a link between concussions and CTE, science has not proven that concussions are a direct cause of CTE. It has quickly risen as a concerning effect of repeat concussions in modern day football.
This paper connects contact sports with degenerative brain diseases. It also shows that CTE is not only connected to football because of the continuous tackling inducing trauma to the brain, but also soccer where heading the ball can often cause brain damage. This is supported by research of retired NFL football players and soccer players whose brains showed evidence of CTE. Also when the Mayo Clinic studying the brains of those who did not participate in contact sports showing no evidence of CTE. Based on scientific evidence degenerative brain diseases such as CTE are caused by successive concussions. Since concussions are one of the most common brain injuries seen in contact sports today there is a definite association between contact sports and degenerative brain diseases.
There is a dark cloud hanging over the world of contact sports and it is growing at an alarming rate. With the size and speed of today’s athletes, the sports of football and hockey have become more exciting, fast paced, wide open, and fun to watch. However, there is another consequence of these ever growing athletes on their sports. They have made the collisions in them increasingly more violent. The velocity that these athletes hurl themselves through the air has created an atmosphere that could not have been imagined when these sports were created. Although the athletes’ bodies have become
