Of course in the area of research around PTSD and operational stress injuries, much research has been done across the world in this area, a lot around PTSD from rape, from accidents, and car accidents. There has been a lot of PTSD research done in the States around the U.S. veterans and military.
In Canada the research is growing, but it's starting. For example, there is research being done right now on the use of certain drugs to limit the impact of the traumatic memories around PTSD. There is research being done around the efficacy of some treatment modalities in conjunction with one another—for example, using drugs and exposure therapy, or cognitive behavioural therapy for conjoints.
So there is a lot of research to better understand how these treatment modalities can be effective for our population of veterans. And the culture in Canada is different, the military environment is different, and the types of operations that we have undertaken in the past are different, so we need some of our research. For example, in one of our clinics we're also doing a research study on the emotional and behavioural impact on children having a parent who has PTSD, which is going to bring us a better understanding of what the issues are so we can direct our treatment efforts in the right direction.
