Post-Concussion Symptoms Scale (PCSS)

This section describes the symptoms and the level of endorsement of those symptoms by the individual. The higher the level of reported symptoms, the more likely it is that the reported symptoms interfere with the individual’s performance. When there are repeated post injury evaluations, the individual’s reported change in symptoms should be carefully considered along with his or her performance on the testing tasks.
