Kathy, IMHO you need to create more polls yourself to possibly answer some of your own questions, and likely even answer or connect the dots for many other carers and/or physicians who gather statistical data from this forum. What you seem to at times be concerned or think about, so do others. I think your thinking is smack on the mark.

IMHO, I would ask that more carers in general ask questions through polls in order to determine a greater understanding whether their sufferers issue is individual or more a PTSD aspect.
