Summary: This study examined post-exertion (PE) neurocognitive performance among student-athletes following concussion who were asymptomatic and returned to baseline normal neurocognitive test levels at rest. A total of 27.7% of 54 concussed student-athletes who were symptom-free and returned to baseline on ImPACT at rest exhibited cognitive decline following moderate physical exertion. The PE cognitive changes were not simply general performance effects, but significant changes in memory ability in the presence of intact processing speed functions. The PE-Pass and PE-Fail groups did not, however, differ on post-concussive symptoms or concussion history. This study supports a recommendation that return-to-play evaluation protocols should include post-exertional computerized neurocognitive testing.
