A concussion is when someone receives a blow to head, face or jaw, or
             any quick movements that would injure the brain stem, or causing a bruise on
             the brain. Common symptoms of a concussion would be: headaches,
             disorientation, dizziness, vacant stares, lack of coordination, amnesia,
             nausea, double vision, and ringing of the ears. These symptoms have been
             known to last for weeks, but usually only last a few hours to a day. There
             are two common types of sports related concussion
             acceleration/deceleration and rotational1. Acceleration happens when you
             are standing still and an object that is moving hits your head. Deceleration

             being the least problematic, and three being the most. A grade one
             concussion has brief confusion and other common symptoms that clear up
             within fifteen minutes. A grade two has brief confusion and other common
             symptoms that last more than fifteen minutes. A grade three has loss of

             is supposed to take time off according to how serious the injury is, if the
             athlete does not take the required time off they can acquire second impact
             syndrome. Post impact syndrome can be more dangerous than the original
             concussion, the effects can be permanent and even cause death. To treat
