The ImPACT Test (Immediate Post-Concussion Assessment and Cognitive Testing) is a widely used tool for assessing cognitive function after a head injury. It measures various aspects of brain function, including memory, attention, and reaction time. This test helps healthcare professionals determine the severity of a concussion and make informed decisions about an athlete's return to play. Typically administered to athletes, the ImPACT Test is often given before the sports season as a baseline measure. If a concussion occurs, the test can be repeated to evaluate any changes in cognitive performance. This information is crucial for ensuring the safety and health of individuals recovering from concussions.
