Post-Traumatic Stress Disorder (PTSD)
What is post-traumatic stress disorder?*
Post-traumatic stress disorder (PTSD) is an anxiety disorder that can occur after someone experiences a traumatic event that caused intense fear, helplessness, or horror. PTSD can result from personally experienced traumas (e.g., rape, war, natural disasters, abuse, serious accidents, and captivity) or from the witnessing or learning of a violent or tragic event.
While it is common to experience a brief state of anxiety or depression after such occurrences, people with PTSD continually re-experience the traumatic event; avoid individuals, thoughts, or situations associated with the event; and have symptoms of excessive emotions. People with this disorder have these symptoms for longer than one month and cannot function as well as they did before the traumatic event. PTSD symptoms usually appear within three months of the traumatic experience; however, they sometimes occur months or even years later.
How common is PTSD?*
Studies suggest that anywhere between 2 percent and 9 percent of the population has had some degree of PTSD. However, the likelihood of developing the disorder is greater when someone is exposed to multiple traumas or traumatic events early in life (or both), especially if the trauma is long term or repeated. More cases of this disorder are found among inner-city youths and people who have recently emigrated from troubled countries. And women seem to develop PTSD more often than men.
Veterans are perhaps the people most often associated with PTSD, or what was once referred to as "shell shock" or "battle fatigue." The Anxiety Disorders Association of America notes that an estimated 15 percent to 30 percent of the 3.5 million men and women who served in Vietnam have suffered from PTSD.
