Post-traumatic stress disorder (PTSD) is an anxiety disorder that is triggered by an event such as violence, a car accident, or a natural disaster. It can affect one person or a group of people. In soldiers it has sometimes been called "shell shock". Symptoms include flashbacks, emotional detachment, and jumpiness. PTSD can make working, and maintaining relationships, very difficult.
