What distinguishes acute stress disorder from post-traumatic stress disorder (PTSD)?

Acute stress disorder is characterized by the onset of symptoms that occur in response to a traumatic event, which can manifest as anxiety, intrusive thoughts, or dissociation. The defining time frame for acute stress disorder is that it emerges within three days to one month following exposure to the trauma. This distinct period distinguishes it from post-traumatic stress disorder (PTSD), which requires symptoms to persist for longer than one month after the traumatic event. Understanding this timing is critical for reaching the appropriate diagnosis and providing effective treatment.

The diagnosis of PTSD involves enduring symptoms for a longer duration, emphasizing the need for monitoring individuals who may experience prolonged effects following trauma. This is crucial for clinicians to identify and intervene accordingly based on the duration of symptoms presented.
