Document Summary
A disturbance in brain function caused by a direct/indirect force to the head. It is a complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces. Rotational: injury at impact site, brain strikes skull on opposite side, brain strikes side on the other side, brain rotates stretches or tears structures/vessels as it shears on itself. Individuals should have more than one of these symptoms to be deemed concussed. Direct blow to head, face, or neck. Elsewhere on body with an impulsive force transmitted to. Impacts of 100-190g; 20 mph with deceleration of 14 mph. There is no agreed upon biomechanical threshold for injury. Force does not factor in/on symptom severity. 21 year old defensive end (division 1) Does not have to be how hard they are hit, could be the position they are in or the rotational forces or the way they fall. Modifiers don"t need to memorize for exam. Second impact syndrome 14 days or so after concussion.
