Acute stress disorder (ASD) is an anxiety disorder characterized by a cluster of dissociative and anxiety symptoms that occur within a month of a traumatic stressor. It is a relatively new diagnostic category and was added to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) in 1994 to distinguish time-limited reactions to trauma from the farther-reaching and longer-lasting post-traumatic stress disorder (PTSD).
