Acute Stress Disorder (ASD)
ASD is a severe anxiety response following exposure to actual or threatened trauma that lasts for 3 or more days, and up to one month. Symptoms from the following categories:
A|voidance of internal memories or external reminders
I|ntrusion (e.g. nightmares, flashbacks)
D|issociation (e.g. derealization, amnesia of the traumatic event, being in a "daze")
A|rousal (e.g. insomnia, startle, hypervigilance)
N|egative mood (e.g. tearfulness)
"AIDAN" mnemonic for the categories of symptoms in acute stress disorder
ASD is characterized by re-experiencing events of the trauma, through symptoms like intrusive memories, flashbacks, and nightmares.
Patients have a higher risk for subsequent PTSD, so monitor if symptoms last longer than 1 month.
