Abstract:
The pathophysiology of concussion may lead to a variety of both short- and long-term effects, which may lead to a decision to retire from contact sports. These effects follow a recognizable progression and may cause an athlete to opt out of play at any point along this progression. To elucidate the effect of concussion or mild traumatic brain injury and weigh in on a decision to retire, the treating physician needs to take into account the history, neurologic examination, brain imaging, and neuropsychological testing. In addition, myriad social factors surrounding play must be taken into consideration.

Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
