As GOP lawmakers grapple with the “replace” aspect of Obamacare and seek to overhaul the subject “nobody knew could be so complicated,” we must remember that one of the best ways to reduce spiraling healthcare costs is to improve health through preventive measures.
For instance, increased participation in youth sports would help control rising obesity and sedentary rates which are responsible for 21% of annual medical spending – a staggering $190.2 billion a year. Inactivity among youth spiked from 20% in 2014 to 37.1% in 2015. But while the NIH identifies preventing weight gain in childhood as critical to warding off lifelong obesity outcomes and playing sports as one of the strongest weapons against teen obesity, participation rates have declined nearly 10% since 2009. A number of factors have been attributed to this trend, but with the biggest losses in contact sports like football and wrestling, it’s impossible to ignore the long-standing elephant in the stadium – concussions.
Current polls show 94% of U.S. adults believe sport concussions constitute a public health concern and a full 100% of parents are affected by them. But do the risks of playing contact sports really outweigh their myriad physical, mental, and social benefits? After decades of research, why do we still not know what to do about concussions?

Eric Lindros, who retired from the NHL after suffering 6 concussions and donated millions to the cause, hit the nail on the head in lamenting the lack of tangible results and guidance from concussion research: “It seems like there are so many groups trying to do the right thing, but our voice would be stronger through consolidation. Are we sharing all the information? Let’s get people working together.”
Lindros’ frustrations are best illustrated by disagreement about what a concussion even is. Google defines it as “temporary unconsciousness caused by a blow to the head.” But only a small minority of medical “consensus statements” (of which there are more than 42) even require a loss of consciousness and most sources say indirect impacts are also sufficient to cause concussion. These differences aren’t just academic – accounting for sport concussions that did not involve loss of consciousness made the prevailing incidence rate jump from 300,000 to 1.8 – 3.6 million annually. Failure to agree on how to define the problem has created a snowball effect, contributing to inconsistent diagnostic standards and unreliable incidence and prevalence data that cannot be aggregated or compared.
