Posttraumatic Stress Disorder is a very common anxiety disorder. In fact, most of the people who are admitted to mental health institutions have PTSD. Recent studies reveal that there is a lifetime risk for PSTD which is set at around 8 percent to 10 percent. Studies also reveal that while many people may be exposed to traumatic events and the likes, not all of them are at risk of having PTSD. Further, experts discovered that women who have been exposed to trauma are more likely to have PTSD than men. Reasons behind this are still subject to further study.
Another interesting discovery is that people who have not directly experienced a traumatic event or occurrence are also at risk of having PTSD. A perfect example for this is the September 11 World Trade Center terrorist attack
Aside from experiences of trauma, which may be direct or non-direct, some of the factors that may lead to a person’s susceptibility to PTSD are pre-existing emotional disorders, abuse of illegal substances like drugs and alcohol, a family history of anxiety or depression or other emotional disorders under the same category, or a personal history of abuse, lack of social support, and sleep disorders.
