Effects of Two Concussions on the Neuropsychological Functioning and Symptom Reporting of High School Athletes.To assess the effects of two sports-related concussions on neuropsychological functioning and symptom reporting, the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) was administered to 483 high school athletes.  The results showed that the three groups did not differ in terms of their ImPACT composite scores (Verbal Memory, Visual Memory, Reaction Time, and Processing Speed) and the Total Symptom Score.
