Ontology: Stress Disorders, Traumatic, Acute (C0236816)

Definition (NCI) An anxiety disorder precipitated by an experience of intense fear or horror while exposed to a traumatic (especially life-threatening) event. The disorder is characterized by dissociative symptoms; vivid recollections of the traumatic event; avoidance of stimuli associated with the traumatic event; and a constant state of hyperarousal for no more than one month.
Definition (MSH) A class of traumatic stress disorders that is characterized by the significant dissociative states seen immediately after overwhelming trauma. By definition it cannot last longer than 1 month, if it persists, a diagnosis of post-traumatic stress disorder (STRESS DISORDERS, POST-TRAUMATIC) is more appropriate.
Definition (PSY) Disorder characterized by the development of anxiety and dissociative symptoms as a result of exposure to a traumatic event. Symptoms last at least two days and no longer than four weeks.
