A transient anxiety disorder following exposure to a traumatic event, with a similar pattern of symptoms to post-traumatic stress disorder plus symptoms of dissociation (such as dissociative amnesia, depersonalization, derealization) but occurring within four weeks of the traumatic event. If the symptoms persist beyond four weeks, then a diagnosis of post-traumatic stress disorder may be considered. ASD abbrev. [From Latin acutus sharpened, from acuere to sharpen, from acus a needle]
