Andrew Klein, an assistant professor of radiology at the Medical College of Wisconsin, led a team of researchers that sought to characterize and compare the prevalence of acute, head-trauma-related MRI findings and nonspecific MRI findings in contact and noncontact athletes with and without sport-related concussion by using data from the NCAA-Department of Defense Concussion Assessment, Research and Education Consortium study.

With concussion and its consequences — particularly among those who play football — emerging as one of the foremost concerns in college sports, two veteran neuroscientists recently joined forces to edit a comprehensive review of sport and the brain.

Sport-related concussion has generated heightened interest among the public and researchers alike during the past two decades, but has clinical management of the injury changed accordingly? A new study suggests it has.

The NCAA-Department of Defense study evaluates college athletes and military cadets alike, and interrogating baseline concussion assessment data from both groups is essential.

While researchers have learned a great deal about concussion in recent decades, what occurs in the brain at the time of injury and through the course of recovery are not yet fully understood.

How is an athlete’s physical quality of life affected in the wake of a concussion?

A litany of factors — testing environment, testing group size and mental health history, plus others — can affect the results of baseline concussion tests. But what role does fatigue play, if any?

Previous studies have found that repetitive head impacts to athletes during adolescence can have potentially detrimental effects much later in life. But what short-term effects might that early-life exposure have?
