Mild Traumatic Brain Injuries

Concussions can truly mess with an athlete’s brain and can give him or her lifelong troubles.

In the U.S. alone, athletes suffer from roughly 300,000 concussions per year; 3,800,000 concussions were reported in 2012, which is double of what was reported in 2002. A concussion may be defined as a type of traumatic brain injury—or TBI—caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in the skull, stretching and damaging the brain cells and creating chemical changes in the brain. Concussions are not usually considered life-threatening, but they may result in effects to the brain that may lead to devastating outcomes. Concussions are serious injuries that need to be taken seriously because of their severity and the serious health disorders that may arise.

Multiple studies have shown that concussions can lead to severe, debilitating, and permanent brain damage. With these consequences in mind, athletes should be required to be evaluated by a physician and sit out longer after receiving any sort of head trauma. Studies have also shown that concussions are cumulative. After someone receives one, their brain is more susceptible to further injury.

When you have a concussion it can be hard to focus, you can have lower test scores, and every time you get a concussion you damage your brain long term more and more [Newsela]. Also, after you get one concussion you have a better chance of multiple concussions, like cognitive impairments, chronic traumatic encephalopathy, and also it can cause post concussion syndrome [Flynn]. 9/10 teens who continue to show symptoms of brain injury have academic problems like headaches and bad concentration. Once you have multiple concussions you can get syndrome like cognitive impairments (MCI's), chronic traumatic encephalopathy (CTE), and post-concussion syndrome (PCS). Headache (85%) and Dizziness (70-80%) are most commonly reported symptoms immediately following concussions for injured athletes [Flynn].“The National Center for Catastrophic Sports Injury Research in Chapel Hill, NC, reported 35 cases of Second-impact syndrome [SIS] among American football players from

Each year approximately about 300,000 sports-related concussions are reported in the United States. The study has found out that an athlete who has suffered 1 concussion are at greater risk of suffering from another concussion. Sport-related concussion is still considered one of the main problem medicine professionals are dealing with. Research has also shown that multiple concussions have had detrimental effects on athletes participating in boxing, men's ice hockey, and men's soccer. Research on multiple concussions has been retrospective, using only posttest designs. Several researchers have suggested that the cumulative effects of repeated concussions can have long-term consequences. Collegiate football players with a history of 3 or more concussions were at 3 times greater risk for suffering another concussion compared with athletes without a history of concussion. Athletes with a history of 3 or more concussions presented more symptoms and poorer memory performance on neurocognitive testing at baseline than athletes with no history of concussion. These findings suggest that a history of concussion may place an athlete at risk for developing long-term sequelae associated with postconcussion

Concussions or mild traumatic brain injuries (MTBI) are the most common forms of traumatic brain injury. There are between 1.6 and 3.8 million concussions a year that occur due to sports and recreation accidents alone (CDC). Mild concussions and MTBIs were once thought to be insignificant in terms of consequences. However, there now is significant evidence that neurological even with what is thought to be a mild injury, physiological, and cognitive changes can occur. Individuals sustaining mild brain injuries often report an assortment of physical, cognitive, and emotional/behavioral symptoms referred to as post concussion syndrome (PCS). There are many symptoms associated with PCS, but these symptoms are often mistaken as behavior, mood, and/or adjustment disorders.

In 2006, The Centers for Disease Control and Prevention estimated that approximately 1.6 million to 3.8 million sport-related concussions occur each year in the United States (Langois, Rutland-Brown, & Wald, 2006). Sport-related concussions are a subset of traumatic brain injuries (TBI) and are defined as a complex pathophysiological process affecting the brain (McCrory et al., 2012). The typical signs and symptoms associated with a concussion include confusion, amnesia, headache, dizziness, nausea, loss of balance, and/or poor concentration (Centers for Disease Control and Prevention, 2010).

A concussion is an mTBI that affects brain function and is caused by a single blow or violent shaking of the head or upper body (Mayo Clinic Staff, 2017). Most sport-related head injuries are minor and although the majority of athletes who suffer a concussion recover within a few days or weeks, a small number of individuals develop long-lasting or progressive symptoms. This is especially true in cases of repetitive concussion or mTBI in which at least 17% of individuals develop CTE (McKee et al., 2015). The incidence rates recorded thus far for concussions is highly likely to be a very conservative number and seriously under-estimates the true incidence. Reasons for this being that: a) reports by associations tend to only record athletes who experience a loss of consciousness (LOC) and b) players and coaches usually lack awareness of or minimize symptoms of

Many of the earliest effects that athletes suffer from, after sustaining a concussion are: headaches, stroke, seizures, nausea, vomiting, internal bleeding, and hydrocephalus, a buildup of fluid in the brain ("Consequences of a Traumatic Brain Injury", 2016). These are all conditions, that an athlete can suffer from within hours or a few days of an initial hit to the head. These conditions range from minor to severe, the most severe being internal bleeding, and hydrocephalus and the minor ones being, nausea and vomiting ("Consequences of a Traumatic Brain Injury", 2016). No matter the severity of the concussion and it’s affects an athlete that has received multiple concussions is more likely to be faced with conditions that are not as noticeable at first, but lead to a life filled with pain and confusion (Brain Concussion Related Diseases & Conditions, 2016). When an athlete has a buildup of cerebrospinal fluid (CSF), this leads to hydrocephalus. Hydrocephalus, may not be apparent when a Traumatic Brain Injury first occurs, but it does occur in the early stages. However a diagnosis may not appear till a year

Health professionals will often interchange between the two terms, concussion and mild traumatic brain injury (mTBI), when discussing this health condition (Halstead, Walter, Council on Sports, & Fitness, 2010). A concussion is a mild traumatic brain injury resulting from a traumatic event which causes the affected individual to experience temporary neurological deficits, these are a result of “biomechanical forces” that have reached the head taking effect on the brain (Jordan, 2013; Paul McCrory et al., 2009; Silver, McAllister, & Yudofsky, 2011). This type of injury usually presents with multiple post concussive symptoms, although in some cases these symptoms do not present themselves until later (Paul McCrory et al., 2009), in which can result in the concussion going unnoticed.

Not every concussed individual experiences long-term effect from concussions unless it is severe. Some of the common short-term effect of concussions includes temporary consciousness loss, confusion, headache, dizziness, or amnesia. However, those who sustain multiple concussions suffer several serious long-term effects which can lead to retirement for sports athletes. These individuals who suffer from concussions for an extended period show different effects of cognitive impairment while others may suffer from visual processing. Thus it becomes hard for one live normally. If an athlete is suspected to have a concussion, he/she should not return to play as it can be dangerous to them and the other players. There are many cases where high-profile professional athletes retire as a result of post-concussion syndrome due to a repetitive concussion.

A concussion or mild traumatic brain injury(mTBI) is an acceleration/deceleration injury resulting from biomechanical forces transmitted to the cerebral tissues from impacts to the head (Broglio). Concussive sport injuries make up the majority of all brain injuries in the United States with 1.6 to 3.8 million cases every year. Every year athletes get bigger, better, faster, and stronger leading to higher collision forces and an increase in concussive injuries. The symptoms of concussions often appear quickly and resolve randomly making it difficult to be identified and diagnosed. Common symptoms of mTBI include

Perhaps one of the least understood injuries is a Mild Traumatic Brain Injury (TBI), otherwise known as a concussion. Over 1,000,000 concussions occur the United States every year (Majerske et al., 2008), and can be caused by any blow to the head. It is likely that many concussions do not go diagnosed. 300,000 of these concussion have been contributed to sports related injury (Majerske et al., 2008), making the study of sports related concussions in athletes the most important and easiest subjects to study.

With an average of 300,000 cases a year in the U.S alone, concussions have become a major topic in the athletic world. (Gessel et. al 2007) In the mid to late 1900’s many people were under the belief that a concussion was not that big of a deal and kids were rarely checked for an injury. It wasn’t until recent years that doctors actually researched concussions and realized that they were a big deal just like any other brain injury. The rise in concussions awareness has happened because of the lasting effects that numerous concussions can have on the brain. These effects can include an increased risk of Parkinson’s disease, Alzheimer's, and Dementia. Because of these new studies professional

Before we can recognize the symptoms, we must first understand what concussion actually is. Minor traumatic brain injury (Mtbi) is the medical term used when there is a sudden onset but brief loss of cognitive function that occurs after a blow or other moderate trauma to the head that jars or shakes the brain inside the skull. Normally, the fluid around the brain acts like a layer of protection that keeps your brain from knocking into your skull. However, with moderate force, the brain can hit the cranial/ mandible and become injured.
