 So my name is Jeff Kutcher. I'm a sports neurologist. I'm the global director of the Sports Neurology Clinic. I'm also the director of the National Basketball Association Concussion Program, the neurologist for US Ski and Snowboard, and a consultant to the NHL and NFL Players Associations. My area of focus is brain health in athletes. So that includes concussions, but also post-concussion syndrome and long-term brain health over the course of a career and a lifetime. So any aspect of neurological injury, from playing sports or even common neurological problems in athletes, that's my area of expertise both clinically and in research. So we are today far better off than we were over a decade ago when concussions and brain health really wasn't a conversation we were having in sports. One of the issues though is we don't have a lot of data that actually speak to long-term outcomes, real clinical outcomes. And there's been this tendency to try and solve concussion problems, whatever they may be in sports, by applying very simplistic protocols, very structured ways of evaluating patients. And as a neurologist, we are trained to examine the brain of a living person, being able to do an examination and a complex history that gives us information about how that brain is operating in real time. And that experience tells us that we can't rely too much on oversimplifying oversimplified protocols to help us. We really need to apply a comprehensive neurological approach to every patient we see, whether it's a simple concussion, quote unquote, during a game or somebody has a more complex history. I think we are, things are improving, but I would say the majority of the progress has not been in data as much as it's been in policies and approaches and education and awareness. It is very difficult to do good clinical studies on something like concussion, because it is a clinical diagnosis, something made by a clinician. And your level of experience and training that you bring into that diagnosis will absolutely affect your ability to have an accurate diagnosis and to also account for other possible explanations for what's going on with that patient. So I think we've had this problem for years in concussion research, where we have not been careful enough at what we're calling concussion to put into the research that we're doing. We must be much better at that going forward if we're going to get good data to help us make decisions. The term concussion has really become something that is very emotional. There's a narrative out there that concussions are sort of the next C word after cancer. It's something that should change your life and lead to all these bad things down the road, and that's not true. Concussions are transient injuries that get better. There are other things from getting your brain-experiencing force that can cause long-term issues, but that's not concussion. So we need to be careful about the words that we use and how we describe things, because right now we have all over America and all over the world youth athletes being concussed. And then that emotional value that people are putting on that term comes to the fore. And you have parents who are very concerned about, oh my gosh, I don't want them to be concussed again. Well, the reality is humans have been being concussed ever since we've been walking, probably before that. And it is part of our natural history to experience concussions. But we have to be careful about how we interpret what the injury is and what it means for the future. What's really fantastic about this event, the Stubman-Philipon Research Institute Second Annual Injury Symposium, is it brings together people. Anytime you can get folks in a room who are clinicians of different types. We have athletic trainers here. We have physicians of different types, really any clinician that touches this issue. In one room to talk about injury and injury prevention, it's incredibly powerful, especially at a place like the Stubman-Philipon Institute, where a very well-respected institute and really just an opportunity to take things to the next level. Well, I think prevention is something that doesn't have to be an absolute, and in some cases, will never be an absolute. You talk about risk of being injured. And the only way to prevent a concussion from sports completely is to not play sports, just like the only way to prevent knocking and car accident is to never drive. Our life is filled with risk. Our job as physicians and clinicians is to mediate risk, to prevent as many as possible and still be able to have that activity as part of a meaningful life.
