Posttraumatic Stress Disorder
Posttraumatic Stress Disorder (PTSD) is a disorder that develops in some people who have experienced a shocking, scary, life threatening, dangerous event, or witnessing such events that may result in emotional trauma.
Not every traumatized person develops ongoing (chronic) or even short-term (acute) PTSD. Not everyone with PTSD has been through a dangerous event. Some experiences, like the sudden, unexpected death of a loved one, can also cause PTSD. Symptoms usually begin early, within 3 months of the traumatic incident, but sometimes appear until years later. Symptoms must last more than a month and be severe enough to interfere with one’s routine of life, relationships or work to be considered PTSD. The course of the illness varies. Some people recover within 6 months, while others have symptoms that last much longer. In some people, the condition becomes chronic.
