Document Summary
Consequences of repeated blood-brain barrier disruption in football players. 5 football teams and filmed football games (university level) and tracked the number of head hits against all the athletes for one season. Everyone afterward was concussion free, but had taken several head hits. Measured protein level in the blood of the athletes (s100b) Blood-brain barrier disruption from sub-concussion leads to surge of s100b protein and an adverse immune response in the brain. Individuals with increased s100b levels showed structural changes via diffusion tensor imagery (dti) Can cause auto-immune response with trauma to blood-brain barrier which might lead to cognitive defect. Able to link this to structural deterioration in the brain (dti = brain structure) Dti provides a measure of axon connectivity within the brain. People with concussions had less axon connections. Women"s soccer have the highest amount of concussions due to heading a soccer ball.
