Heading the Ball in Soccer: What's the Risk of Brain Injury?

Concern exists that heading the ball in soccer may cause brain injury. Studies using EEG, CT, neurologic exams, and neuropsychological testing have not clearly established that the practice is hazardous. Studies generally have shown no neuropsychological differences between soccer players and other athletes, but some have revealed differences between soccer players and nonathletes. Because of the uncertainties, the authors advocate use of correct heading technique, enforcement of game rules, and increased awareness of the potential for injury from heading the ball.
