Let me compare it to another condition, such as cancer. If you see a cancer and that it's responsive to a certain kinds of hormones, for example, if it's hyperactive, then what kind of treatment do we use for that particular individual? The treatment is not going to be the same, and that's exactly what we need to do for people with mental illnesses, including post-traumatic stress disorder. We need to understand the individual difference and how to treat that person rather than a category of illness. We're not there yet, but we need to get to that point of personalized intervention.
