Document Summary
Concussion: a complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces . Can be linear or rotational when theyre linear we worry about injury at the impact site and sometimes the opposite side where the skull hits the brain. Rotational: brain rotates- stretches or tears structures/vessels as it shears on itself. Nausea, visual issues, mood swings but everyone is different. If were banking on one thing were screwed and so is the athlete. Black and white symptoms: i have a headache or i don"t. Things like emotionality, anxiousness, etc are harder to identify, theyre not so black and white. If we hang our hat on one or even two symptoms, we could be missing something big. A direct blow to the hea, face or neck, or. Elsewhere on the body with an impulsive force transmitted to the head . Force does not factor in on symptom severity. Helmets can only partially absorb impact from 80 40 g.
