Post-traumatic stress disorder (PTSD) can occur in people who have experienced or witnessed a traumatic event such as a serious accident, a terrorist act, war, a natural disaster, fire, flood, rape, or other violent personal assault.
People who have experienced trauma often continue to have intense, intrusive, and disturbing thoughts and feelings related to their experience. These can last long after the traumatic event has occurred. The individual may:
- Relive the event through flashbacks
- Have feelings of sadness, fear, or anger
- Feel detached from other people
- Avoid situations or people that remind them of the traumatic event
