In the research that we did for the department in rural communities, we were not focused particularly on mental health, so I can't address your question directly about PTSD.
Certainly we met with veterans, some of whom were very active and engaged and quite well, and others who were needing nursing-home-level care. So we saw a huge variety of health status and mental health status among the veterans and other older adults we talked to. I can't specifically say whether or not people we met were suffering from PTSD because we weren't really asking those questions.
