Thank you again, especially today, on Let's Talk Day; it's so important to recognize the mental health implications of concussion. They are there, and it is something that we've continued to study to better understand.
I think we have to be very careful about how we use the word “cause”. We have to use the word “association” at this point, because we don't know yet which is chicken and which is egg. Is it the fact that people who are predisposed to, or who would later in life go on to have, such mental health-related illnesses as anxiety, depression or other associated mental health problems are more likely to have ongoing mental health symptoms after their injury? We do have research indicating that there may be an association, not with regard to their physical symptoms but with regard to their ongoing mental health symptoms. Is it the fact that the concussion has now triggered and exposed this? For many things in life, an exposure changes your DNA. You can have your DNA changed by exposures. That's what causes many illnesses. Is there something with regard to the injury that has changed the brain, either through DNA or blood flow, etc.? That's something we still need to work on. I think that's an opportunity to study.
Did you have a follow-up question?
