At-risk athletes will take a baseline neurocognitive test. Baseline tests should be repeated every two years in the high school athlete. Following a concussion, a post-concussion test will be administered 24-72 hours after the concussion. Depending on post-concussion results, it may need to be repeated when the athlete is asymptomatic until post-concussion results improve to within baseline values. Test values will be reviewed and compared by a sports medicine provider or one of the other Union Medical Group physicians. Student athletes that belong to schools not associated with Union Health Sports Medicine program can request an ImPACT baseline test by scheduling an appointment.
