9 Department of Electrical and Computer Engineering  Current concussion detection Train coaches to recognize symptoms  Players may hide or not experience symptoms right away Concussion Detection in High School Football What is the problem?

10 Department of Electrical and Computer Engineering How significant is the problem?  1.6 – 3.8 million sports-related concussions in the United states every year Have reached “epidemic level”  Not only professionals Young people ages 15 – 24 years -Second leading cause of TBI (Traumatic Brain Injury)

11 Department of Electrical and Computer Engineering  Post Concussion Syndrome Problems concentrating, irritability, sensitivity to light…  If gone undiagnosed One hit away from traumatic brain injury Multiple impacts add up Context: Effect on Individuals

12 Department of Electrical and Computer Engineering Context: Effect on Groups  Affects team sports and the way they’re played  “Tough guy attitude” Creates a culture  Subjective decision making
