I think that's a very good point that you raised.
One of the things that we have done in partnership with the Mood Disorder Society of Canada and CDRIN is to develop curriculum—maybe I'll have Dave talk about the specifics—that actually helps clinicians identify PTSD much more rapidly in the primary care setting. That's one way. The other way is, you're absolutely right in the sense that people need to know what those early signs and symptoms are so that they or their families can begin to identify an issue before it reaches a critical stage.
There are devices being developed right now, for example, mobile cell technology. On your cell phone you can access programs that can help you answer a few easy questions, and they will indicate to you whether you might be at risk for PTSD or not, whether you might be suffering from it or not. Then you need to go to your physician or clinician for the next steps.
But the lack of awareness and the lack of knowledge about the signs and symptoms is a critical issue for PTSD and for depression as well.
We had a recent symposium where we had brought in managers from the workplace. We asked how many of them would recognize depression if it walked into the room. Three hands went up out of a hundred. People just don't know how to recognize these things. I think that the work that's being done by the Mental Health Commission of Canada in developing some of the working tools and early intervention strategies are very important.
