What is Acute Stress Disorder?
Acute stress disorder can occur after a person has experienced, witnessed or been confronted with an event or events that involved actual or threatened death or serious injury, or a threat to the physical integrity of the person or others.
Disturbing memories of the traumatic event cause an emotional reaction and a sense of reliving the event.
Symptoms start to appear within one month of the traumatic event. Symptoms that occur after a longer period may mean the person has developed posttraumatic stress disorder
