ImPACT stands for Immediate Post-Concussion Assessment and Cognitive Testing. It is a computerized test used to evaluate an athlete's cognitive function after a head injury. The assessment measures various aspects of brain function, including memory, attention, and reaction time, helping healthcare professionals determine when it is safe for an athlete to return to play. The ImPACT test is often used in sports settings, particularly for contact sports like football and hockey. It provides a baseline measurement before the season starts, allowing for comparisons after a concussion. This helps ensure that athletes do not return to play too soon, reducing the risk of further injury.
