Acute stress disorder (ASD) is characterized primarily by the timeframe in which symptoms arise and their duration. This disorder can occur immediately after a traumatic event and typically lasts from three days to one month. If symptoms persist beyond one month, the diagnosis may shift to post-traumatic stress disorder (PTSD).

In contrast, PTSD is diagnosed when symptoms extend beyond a month and can arise at any point after the trauma. This key distinction in both the timing of symptom onset and the duration helps clinicians differentiate between the two conditions, guiding appropriate treatment and support.

Other factors such as the severity of the traumatic event, therapy types, and gender-related prevalence may vary but do not serve as defining characteristics that differentiate acute stress disorder from PTSD. Understanding these nuances is crucial for accurate diagnosis and effective intervention for individuals experiencing post-traumatic stress reactions.
