The word “concussion” derives from the Latin verb concutere which means “to shake violently. To put it simply, a concussion can be described as; a blow to the head which in turn creates a plethora of physical and cognitive symptoms. Knowing general information about concussions is common. People understand how they happen and how to take care of them. They understand that it has something to do with hitting your head and moving your brain. However, the actual disruption of homeostasis caused by a concussion is astounding. Not only is it one of the most potentially crippling and fatal injuries, it is also not talked about nearly enough. The brain is surrounded by a layer of cerebrospinal fluid, supplied by the dura, which is attached to the …show more content…
When the brain bounces against the skull, it can cause linear or rotational movement of the brain. Linear forces causing movement of the brain are common in car accidents, when the head accelerates forward and hits an object, such as the steering wheel or dashboard. Upon striking the dashboard, the head comes to a sudden stop. When the head stops moving, the brain then bounces off the frontal portion of the skull and begins moving backwards, rebounding off the back of the skull. When the brain accelerates forward, the force of making contact with the frontal bone causes a bruise and is known as coup. The reaction of being jarred forward, rebounds the brain off the back of the skull, bruising the brain, which is known as contra coup. Rotational movement of the brain occurs when there is an impact to the side of the head which results in the brain experiencing an “angular acceleration around the midline axis” (2). Rotational forces are common when someone gets punched or when a football player is tackled. With rotational movement, if the force is great enough, it can cause twisting of the brainstem. Injury to the brainstem results in tearing or stretching of brain tissue. When the brainstem is twisted and pressure is applied, breathing and other basic functions become …show more content…
Even if symptoms from the initial concussion seem to have subsided, if the brain has not healed, even a sudden jerk of the body or blow to the chest could be enough to affect the brain. When this happens, typically the person does not lose consciousness, however, they do become dizzy and within they collapse to the ground. Their pupils will quickly become dilated or even their eyes will stop moving and they will have difficulty breathing. Since concussion causing impacts cause damage to the cerebral cortex, second-impact syndrome could cause some serious permanent
