Post-traumatic stress disorder (PTSD) is a trauma and stressor-related disorder anxiety disorder that develops after a traumatic event. PTSD has also been called "shell shock" or "battle fatigue."
The exact cause of PTSD is unknown. PTSD is triggered by exposure to a traumatic event. Situations in which a person feels intense fear, helplessness, or horror are considered traumatic. PTSD has been reported in people who experienced:

There are many treatments available to help manage PTSD. General goals include learning how to cope with symptoms, reducing symptoms, and strategies to improve relationships with family or friends. Treatment will also focus on any other conditions you may have, such as depression or substance abuse. The length of treatment will depend on the individual but can range from a few months to a few years. Treatment can often include a combination of approaches.

During this type of therapy, you are asked to talk about the traumatic event, including your memories, feelings, and sensations. While talking, you will be asked to do simple tasks like hand-tapping, following therapist's hand with your eyes, or listening to tones through headphones. The reason why is not clear, but repeating the story with the physical distraction allows your brain to process the trauma in a different way. In effect the process overwrites some of the negative thought processes related to the trauma.
Other therapeutic options that may help include:
Medication can help manage some symptoms while you go through counseling or during a crisis period. They may help manage anxiety, depression, and insomnia. Antidepressants known as selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs) are often prescribed.
The events that trigger PTSD cannot be predicted or prevented. However, there are some factors that might prevent PTSD from developing after a traumatic event, such as:
