Yes, exactly. Post-traumatic stress is obviously one of the main disorders caused by exposure to a traumatic event, but there are also other disorders that can develop. They include depression, other anxiety disorders, panic disorder with agoraphobia, for example, or simply panic attacks, and so on.
Mental health issues at National Defence or in the Canadian Forces do not only involve PTSD. In fact, there are others that are far more prevalent than post-traumatic stress.
