Validation of Brain Function Assessment Algorithm for mTBI/Concussion in College Athletes

EEG, neurocognitive performance and clinical data will be collected at time of injury (within 3 days) at clinically determined Return to Play (RTP) and 45 days after RTP, for the purpose of independently validating the performance of the algorithms developed in prior studies (NCT02477943, NCT02661633 and NCTXXXXXX). Data collected under this study will be combined with that collected under NCT03671083 for the final analyses of prospective algorithm performance in an independent population ages 13-25 years. Subjects will come from the sports and other populations of concussed individuals. They will be matched with controls i.e. not head injured subjects who will also undergo the same set of tests and the same time intervals as the injured subjects. An additional pool of uninjured (not head injured) subjects will be collected who will be assessed at a single time point.
