Key Takeaway: Acute stress disorder (ASD) is a temporary but serious mental health condition that can develop within one month of experiencing trauma. With proper treatment—primarily trauma-focused cognitive behavioral therapy—most people recover within six months and can prevent the development of long-term PTSD.
What Is Acute Stress Disorder?
Acute stress disorder (ASD) is a mental health condition that develops within the first month after experiencing or witnessing a traumatic event. Unlike other stress reactions, ASD involves severe symptoms that significantly interfere with daily functioning and last between three days and four weeks.
The condition was first officially recognized in the DSM-IV in 1994 to help people receive early treatment and prevent the development of post-traumatic stress disorder (PTSD). Today, ASD is classified in the DSM-5 under “Trauma and Stressor-Related Disorders.”
Key Features of Acute Stress Disorder
- Timeline: Symptoms appear within one month of trauma and last 3 days to 4 weeks
- Severity: Symptoms cause significant distress and impair daily functioning
- Reversibility: With treatment, most cases resolve completely within six months
- Prevention: Early intervention can prevent progression to chronic PTSD

| Aspect | Acute Stress Disorder | PTSD |
|---|---|---|
| Onset | Within 1 month of trauma | Can occur months or years later |
| Duration | 3 days to 4 weeks maximum | At least 1 month, often years |
| Symptoms | Similar but time-limited | Persistent and chronic |
| Prognosis | Usually resolves with treatment | May require long-term management |
Important: About 50% of people with untreated ASD may develop PTSD, making early intervention crucial.
Comprehensive Symptoms of Acute Stress Disorder
ASD symptoms fall into five main categories, and individuals must experience at least nine symptoms across these areas:
1. Intrusive Symptoms
- Flashbacks: Vivid, involuntary re-experiencing of the traumatic event
- Nightmares: Disturbing dreams related to the trauma
- Intrusive memories: Unwanted, distressing thoughts about the event
- Physical reactions: Intense distress when reminded of the trauma
2. Avoidance Symptoms
- Thought avoidance: Deliberately avoiding memories, thoughts, or feelings about the trauma
- Situational avoidance: Staying away from people, places, or activities that trigger memories
- Social withdrawal: Isolating from family, friends, or normal activities
3. Arousal and Reactivity Symptoms
- Hypervigilance: Constantly scanning for danger
- Exaggerated startle response: Jumping at unexpected sounds or movements
- Sleep disturbances: Difficulty falling asleep, staying asleep, or restless sleep
- Concentration problems: Trouble focusing on work, school, or daily tasks
- Irritability: Increased anger, aggression, or mood swings
4. Dissociative Symptoms
- Depersonalization: Feeling detached from yourself or like you’re in a dream
- Derealization: Feeling like the world around you is unreal or distorted
- Dissociative amnesia: Unable to remember important parts of the traumatic event
- Emotional numbness: Feeling disconnected from emotions
5. Negative Mood and Cognitive Symptoms
- Persistent negative emotions: Ongoing fear, horror, anger, guilt, or shame
- Inability to experience positive emotions: Loss of happiness, satisfaction, or love
- Negative beliefs: Distorted thoughts about oneself, others, or the world
- Hopelessness: Feeling like the future holds no promise
What Causes Acute Stress Disorder?
Traumatic Events That Can Trigger ASD
Life-threatening situations:
- Natural disasters (earthquakes, floods, fires)
- Serious accidents (car crashes, workplace incidents)
- Physical or sexual assault
- Combat exposure or witnessing violence
- Medical emergencies or life-threatening illnesses
Witnessing trauma:
- Seeing someone die or be seriously injured
- Observing violence or accidents
- Learning about trauma to a close family member or friend
Risk Factors for Developing ASD
Biological factors:
- Previous mental health conditions (depression, anxiety)
- Family history of mental health disorders
- Gender (women are at higher risk)
- Age (can occur at any age but more common in adults)
Psychological factors:
- Previous trauma exposure
- Poor coping strategies
- High anxiety sensitivity
- Tendency toward catastrophic thinking
Social factors:
- Lack of social support
- Recent stressful life events
- Social isolation
- Financial or relationship problems
Professional Diagnosis of Acute Stress Disorder
Diagnostic Criteria (DSM-5-TR)
A mental health professional will assess for:
- Trauma exposure (directly experiencing, witnessing, or learning about trauma)
- Symptom presence (at least 9 symptoms from the five categories)
- Timing (symptoms begin within 1 month and last 3 days to 4 weeks)
- Impairment (significant distress or functional problems)
- Exclusions (symptoms not due to substances or other conditions)
Assessment Tools and Interviews
Clinical interviews:
- Structured Clinical Interview for DSM-5 (SCID-5)
- Acute Stress Disorder Interview (ASDI)
- Child Stress Disorders Checklist (for children)
Self-report measures:
- Acute Stress Disorder Scale (ASDS)
- Stanford Acute Stress Reaction Questionnaire
- Impact of Event Scale-Revised (IES-R)
Evidence-Based Treatment Options
Primary Treatment: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT)
Components of TF-CBT:
- Psychoeducation: Understanding trauma responses and ASD symptoms
- Stress management: Learning relaxation and coping techniques
- Cognitive restructuring: Identifying and challenging trauma-related thoughts
- Exposure therapy: Gradually facing trauma-related memories and situations
- Relapse prevention: Developing long-term coping strategies
Treatment timeline: Typically 5-8 sessions over 4-6 weeks
Effectiveness: 70-80% of people show significant improvement with TF-CBT
Medication Options
While psychotherapy is the primary treatment, medications may help in certain cases:
First-line medications:
- SSRIs: Sertraline (Zoloft), paroxetine (Paxil), fluoxetine (Prozac)
- SNRIs: Venlafaxine (Effexor)
Adjunctive medications:
- Prazosin: For nightmares and sleep problems
- Short-term benzodiazepines: Only for severe anxiety (use with caution)
Important: Medications are typically used alongside therapy, not as standalone treatment.
Alternative and Supportive Treatments
EMDR (Eye Movement Desensitization and Reprocessing):
- Effective for trauma processing
- May be used when traditional therapy isn’t sufficient
Group therapy:
- Peer support and shared experiences
- Particularly helpful for specific trauma types (veterans, assault survivors)
Family therapy:
- Helps family members understand and support recovery
- Addresses relationship impacts of trauma
