Post traumatic stress disorder is described as a disorder that develops in some people who have experienced a shocking, scary, or dangerous event, according to the National Institute of Mental Health. It is broken down into two categories: chronic (ongoing) or acute (short term). In order to classify it as PTSD, the symptoms must last more than a month and be severe enough to interfere with relationships or work. Recovery times vary, depending on the individual and whether it is chronic or acute.
It also is a condition that requires at least one reoccurring symptom, at least one avoidance symptom, at least two arousal and reactive symptoms, and at least two cognition and mood symptoms, according to the institute. Triggers for these symptoms can include words, situations, or objects that remind the individual of the traumatic event that they experienced.
