As far as PTSD is concerned, I'd just like to elaborate on that because oftentimes when you're talking about an illness, you automatically assume that you have the illness and you're diagnosed. How it really works is that you can have signs and symptoms and never be diagnosed because you've got the appropriate treatment, and it hasn't lingered.
In order to be diagnosed, you have to go to a subject matter expert, a psychologist who does an evaluation based on questionnaires, pre-testing, and who then has an interview with you. For somebody to say that they have PTSD, it means that they've gone through all those hurdles to be diagnosed with the illness. Can somebody come to you and say, “I have PTSD symptoms”? Absolutely. I'm sure everybody in this room could look at the diagnostic manual and say, “Well, I've had that before.” In order to really say that you have a diagnosis of PTSD, or whatever mental illness it is, there are many hurdles that you have to go through, like meeting with a psychologist, like filling out questionnaires, and even more questionnaires, and having a formal interview. Then that subject matter expert will give you his professional opinion of whether or not you meet the diagnostic criteria. Everything up until that point is signs and symptoms.
