Is the cause of PTSD simply a traumatic event?
Although PTSD begins after a traumatic event, other factors also play an important role. The severity, type, and circumstances of the traumatic event may determine whether or not a person develops PTSD. In addition, some individuals appear to be more vulnerable to PTSD. It is possible that underlying differences in the makeup of a person’s personality or brain physiology may contribute to the onset of PTSD.
