A growing body of data suggests a link between repetitive SRCs and short- and long-term neurological consequences. These findings have been transformative in today's sporting world, with the implementation of numerous rule changes and increased educational endeavors focusing on SRCs. Although future research in the field of TBI appears promising, with continued identification of underlying pathophysiological processes and possible therapeutic pathways, prevention remains the ideal strategy for protecting athletes. Continued education of athletes, parents, coaches, and health care providers regarding recognition and management of SRCs is of the utmost importance as we continue to investigate this issue.
