What is the Difference Between Acute Stress Disorder and Post Traumatic Stress Disorder?

🆚 Go to Comparative Table 🆚

Acute Stress Disorder (ASD) and Posttraumatic Stress Disorder (PTSD) are both trauma- and stressor-related disorders that share similar symptoms but differ in terms of onset, duration, and prognosis. Here are the key differences between the two:

  1. Onset and Duration: ASD typically begins immediately after a traumatic event and lasts from 3 days to 1 month, while PTSD can be a continuation of ASD or may manifest up to 6 months after the trauma and lasts for more than 1 month. Symptoms of ASD last between 3 days and 4 weeks, while symptoms of PTSD must last for at least a month and may persist for several years.
  2. Prognosis: Around 1 in 2 people with ASD will go on to experience PTSD. Experiencing more dissociative symptoms could increase the chances of developing PTSD.
  3. Symptoms Experienced: While both disorders share similar symptoms, such as reexperiencing the event, avoidance, emotional numbing, and altered arousal, ASD is characterized by symptoms that follow immediately or shortly after a traumatic stressor, either experienced personally or witnessed.
  4. Diagnosis: Diagnosis for both disorders is based on clinical criteria. Mental health professionals such as psychologists or psychiatrists can diagnose ASD or PTSD.

Both ASD and PTSD require early intervention and treatment for the best recovery outcomes. It is essential to understand the differences between these two disorders to provide appropriate treatment and support for individuals affected by trauma.

Comparative Table: Acute Stress Disorder vs Post Traumatic Stress Disorder

Here is a table comparing the key differences between Acute Stress Disorder (ASD) and Post Traumatic Stress Disorder (PTSD):

Feature Acute Stress Disorder (ASD) Post Traumatic Stress Disorder (PTSD)
Onset Symptoms arise immediately or shortly after a traumatic stressor Symptoms can manifest after a month or even years after the traumatic event
Duration Symptoms last for 3 days to 1 month Symptoms last for more than 1 month and can persist for years
Diagnosis Diagnosed if symptoms have lasted between 3 days and 1 month Diagnosed if symptoms have lasted for more than 1 month
Progression ASD can potentially lead to PTSD, but PTSD does not lead to ASD PTSD can follow after ASD, but it can also occur even when ASD does not develop
Symptoms Characterized by symptoms such as detachment, derealization, and maintaining daily routines Symptoms include intrusive thoughts, nightmares, flashbacks, and avoidance of reminders of the event

Both ASD and PTSD are triggered by exposure to a traumatic event, and they share some similarities in terms of symptoms. However, the main differences lie in the onset, duration, and progression of the disorders.
