The impression I got was that with the checkup every two years, there's a part of the questioning, part of the interrogation, I guess, or the process, that would identify it. Often what happens is people don't really realize what's going on. They know there's a buzz in their head, they know there's something going on, they're not thinking straight, but they don't really know why. Even with simple depression or something like post-traumatic stress disorder, you don't really know what's going on. You know something's not working, but you're not really sure what it is. And you don't always go forward and say, “Well, you'd better check me for this area.”
I would have thought the checkup would identify or would ask the questions that would lead the person or the professional to identify the illness that is present.
