Acute Stress Disorder
Acute stress disorder is a brief period of intrusive recollections occurring shortly after an overwhelming traumatic event. It is similar to posttraumatic stress disorder, except that it begins within 4 weeks of the traumatic event and lasts only 2 days to 4 weeks.
People with acute stress disorder have been exposed to a terrifying event. They mentally reexperience the traumatic event, avoid things that remind them of it, and have increased anxiety. They also have three or more of the following symptoms (called dissociative symptoms):
A sense of numbing, detachment, or lack of emotional responsiveness
Reduced awareness of surroundings (for example, being dazed)
A feeling that things are not real
A feeling that they are detached from themselves or that they are not real
An inability to remember an important part of the traumatic event
The number of people with acute stress disorder is unknown. The likelihood of developing acute stress disorder is greater when traumatic events are severe.
Many people recover from acute stress disorder once they are removed from the traumatic situation and given appropriate support in the form of understanding, empathy for their distress, and an opportunity to describe what happened and their reaction to it. Some people benefit from describing their experience several times.
Sometimes doctors temporarily give drugs to help people sleep, but other drugs (such as antidepressants) are usually not given.
