An estimated 90 million to 100 million Americans will tune in to look at the Super Bowl this Sunday. Unlikely to be talked about in the course of the festivities is that this sobering however vital facet observe: Athletes taking part in collision sports activities are amongst these at highest threat for concussion.
That threat just isn’t restricted to skilled soccer. Researchers estimate that 4 million sports activities and recreation-related concussions happen within the U.S. yearly, throughout all sports activities and all ranges of play and in each video games and practices. They occur to athletes and children enjoying basketball and soccer and weekend warriors who bicycle and ski. But 1000’s of concussions additionally consequence from automobile accidents, slips and journeys or different blows to the pinnacle.
I’m the director of the University of Michigan Concussion Center, and I’ve been researching mind accidents for almost a quarter-century. Across the globe, a whole bunch extra researchers like me have devoted their careers to understanding concussions and traumatic mind accidents – and, most critically, how one can forestall and deal with them. While large progress has been made, way more stays to be executed.
How harmful are concussions? The reply is sophisticated.
The backstory
When I started my profession, concussions had been broadly considered as “getting your bell rung.” It was not unusual for an athlete who had been knocked out to be despatched again right into a sport inside 20 minutes of damage.
The devastating outcomes of repeat concussions with out acceptable remedy led to the adoption of sweeping laws that particularly addressed youth sports activities concussions.
That laws, enacted between 2009 and 2014, is regulation in all 50 states. Although it varies from state to state, youth athletes now obtain annual training on concussions. Those suspected of getting a concussion have to be faraway from play, and concussed athletes can’t play their sport till cleared by a medical skilled.
In 2005, researchers found the primary case of persistent traumatic encephalopathy in a former skilled soccer athlete. The degenerative mind illness is characterised by protein deposits which have been linked to concussions and repeated head impacts.
This monumental discovering occurred concurrently with U.S. navy involvement in Iraq and Afghanistan. For each conflicts, traumatic mind damage turned the signature damage of returning veterans, and the U.S. authorities elevated funding to check short- and long-term results of concussion.
In addition, sports activities organizations reversed their prior stance and acknowledged the hyperlink between concussions and long-term damage. They started supporting insurance policies that embraced evidence-based rule modifications to scale back concussion threat.
Even younger athletes can maintain concussions when enjoying contact sports activities like soccer, basketball and soccer.

A golden age of concussion analysis
Those occasions laid the muse for a brand new technology of scientists to discover exact methods to diagnose concussions, develop novel remedy choices and perceive who’s most in danger for adverse long-term outcomes.
That contains three transformative research which might be at present underway within the U.S.: TRACK-TBI, which is evaluating 3,000 sufferers throughout traumatic mind damage spectrum; NFL-LONG, which tracks former NFL gamers; and the CARE Consortium, which has enrolled greater than 55,000 navy service academy members and collegiate athletes to higher perceive the short- and long-term results of concussion.
The CARE Consortium, which I co-lead, has produced greater than 100 peer-reviewed papers which have contributed to general enhancements in concussion analysis and administration. Notably, we reported that restoration from a concussion could take as much as one month. We additionally found that female and male athletes return to post-concussion play on the similar fee and recognized blood-based markers which will ultimately function the gold normal for concussion analysis.
My colleagues and I at the moment are beginning follow-up evaluations of the CARE Consortium contributors to higher perceive the long-term results of damage. Those findings, together with work from different research, will inform researchers on the chance of long-term neurodegeneration and shine a lightweight on methods to intervene with medicines and therapies.
The future
Concussion analysis is flourishing. Since the primary trendy case of persistent traumatic encephalopathy was recognized 17 years in the past, greater than 13,000 papers have been revealed within the medical literature. Although researchers have way more to be taught, the advances in concussion care over the previous 20 years are clearly vital. Concussed athletes at the moment are saved off the enjoying area considerably longer, standardized evaluation protocols are widespread and guidelines are in place to scale back concussion threat.
Findings from these research won’t ever seize headlines because the Super Bowl does, and a few could say that coverage modifications ought to occur sooner. Admittedly, the scientific course of is gradual, however selections primarily based on restricted analysis are not often, if ever, the fitting determination. But sooner or later, this largely unheralded work will hold sports activities protected and its contributors entire in physique and thoughts.
