Document Summary

Marchi et al. (2013): consequences of repeated blood-brain barrier disruption in football players. There is a disruption in the blood-brain barrier due to the sub-concussion leading to a surge in s100b protein and an adverse (preventing) immune response in the brain. An individual with increased s100b levels has shown structural changes through the diffusion tensor imagery. This protein causes an autoimmune response in the body (very bad) the protein attacks the cortex leading to deterioration of the cortical structures. Possibly leads to a long-term consequence of declination of cognitive function in the athlete. There is now a very simple blood test to determine the long term risk. Due to the heading the soccer ball, women"s soccer had the highest incidence of concussion (brain scans taken through dti diffusion tensor imaging) Dti technique is relatively new and it evaluates brain structure.
