Checklist: Post-Traumatic Stress Disorder
People struggling with PTSD develop symptoms after experiencing a traumatic event in which their lives were at risk, such as accidents, war, rape, crime, natural disasters, and other similar events. Or, their symptoms developed after they witnessed or experienced an event in which someone else’s life was at risk.

-
People who are diagnosed with PTSD experience three different types of symptoms:
-
1. Reliving or reexperiencing the traumatic event
-
2. Avoiding situations, thoughts, and activating events related to the trauma
-
3. Experiencing increased distress levels as a result of the trauma
-
PTSD is diagnosed when a person has experienced these symptoms for longer than one month. If a person experiences these symptoms immediately after a trauma or for less than one month, a diagnosis of acute stress disorder would be made. Acute stress disorder shares many of the same symptoms as PTSD and the treatment is often similar.
