Following its diagnoses after Vietnam, PTSD is now understood to be much a condition that can occur under a much broader set of circumstances. PTSD is a reaction that can occur having either experienced or witnessed anything that the individual found horrifying, stressful or distressing. Meaning PTSD is not something that occurs only if you return from a conflict zone or experience war, but rather can be experienced as the result of being a part of, or witness to, any trauma event. These traumas can include:
- Being attacked in some way
- A bereavement
- Personal assaults such as; sexual assault, rape, mugging, bullying, robbery
- Prolonged abuse
- Surviving or being witness to a terrorist attack
- Seeing someone else hurt or killed
- Being kidnapped or held hostage
- Going through a traumatic birth or witnessing a traumatic birth
- Being a part of a natural disaster such as an earthquake, tsunami or avalanche
