Almost every one has sustained a concussion at least one time in their lives, whether it was because of a sport or some accident outside sports. However, some people do not know that they have sustained a concussion before because it goes unrecorded. There are fewer concussions recorded on a teenage football practice field than in a game setting, but this is because there are less trained eyes on the practice field compared to the football field when looking for concussions.
According to the University of Pittsburgh, concussions are brain disturbances that can happen from impact to the head. Some symptoms of concussions are loss of memory, nauseous, vomiting, and sensitivity to light. There are some guidelines that are set in high school’s to prevent and detect concussions. For example, in my school we have the impact test that was a baseline test that every athlete has to take. This test had different simulations that included memorizing shapes, numbers, and patterns. If an athlete had any type of head injury, they would have to retake the impact test, and if they failed they would get diagnosed with a concussion. However, some athletes do not know when they have sustained a certain head injury, so sometimes these concussions get overlooked.
According to Tara Haelle, if more than one concussion occurs to a specific individual over the span of a year, the recovery time increases to 2-3 times longer than if you were to sustain your first concussion. This study provides evidence that every individual who participates in sports should be careful and take precaution if they think that they have a concussion. Tara Haelle also stated in her article that 70 to 90 percent of concussions in sports go unnoticed. That’s an overwhelming amount of people who don’t know that they have sustained a concussion.
In this study, the median went from 11 days of recovery time on the first concussion, to 22 days if the subject had a history of concussions. The science behind this is because the brain cells have not fully recovered from the previous concussion, so it takes longer to heal. Because of this, there are more brain cells that have been damaged. The putative causal variable for this study is how many concussions occurred to the subject before the most recent concussion was sustained. The putative response variable for this study is how long it takes for the subject to heal from the most recent concussion. There is no way this study could be reverse causation because of the passage of time. There could be a third confounding variable behind this study because we do not know if the study was controlled against the third variables. Chance is always a possibility in these studies, but it is highly unlikely. The mechanism that causes the longer recovery time is the impact that damaged more brain cells.
In conclusion, a smart individual will pay more attention to if they are obtaining these injuries and if they are getting checked out when they do. If a concussion is spotted, the necessary recovery time must be obtained in order to protect themselves from getting another concussion.
