Essentially, the core of that is to say that some education initiatives exist—and as we mentioned, there needs to be more work on these—but the literature shows that not a lot of them include explicit mention of the mental health effects of a concussion. People don't necessarily realize that this is something that can happen, and when it does happen, you have worse effects.
It's about making sure that people are aware of this, both the people who might suffer a concussion and those around them, so that we know what to do about it.
