Document Summary

Marchi (2013) consequences of repeated blood brain barrier disruption in football players. Tracked how many head hits these football players had gotten over the course of the system (tracked 5 teams) Measured a protein called the s1000b, this protein shows up when there is a disruption in blood brain barrier. (this protein attacks the axons and leads to deterioration) The blood coming into your brain can create a auto immune response. Women"s soccer has highest incidence of concussions. Links this to structural deteriorating of the brain. Dti: diffusion tensor imaging, evaluates brain structure provides a measure of axon connectivity (what axons connect to what) Reduced axon connections when there was high s1000b protein. Now have a blood test and an imaging technique for concussion test. Used a rtms machine to turn down the left hemisphere so that the right can more freely express itself. The testing that he used with the patient increased after the rtms machine.
