I think it can shape the symptoms. For example, in a long-term-care facility what you can have is someone who was in a prisoner of war camp who experienced all the things that go along with that and then functioned very well. And now they're in a long-term-care home because of their Alzheimer's disease, and when the nurses come in the middle of the night to wake them up for some reason or another, it can trigger reactions that are based on previous experiences. That can happen to anyone with Alzheimer's. They can have in their demented state previous experiences triggered, but the nature of the kinds of experiences the veterans might have available to be triggered may be connected to their previous experience.
