Acute Stress Disorder: Causes, Risk Factors, Symptoms, Treatment

Acute Stress Disorder

Acute Stress Disorder, abbreviated as ASD, is a complex and multi-faceted psychological response to an alarming or traumatic event. Historically, it was understood as a transient precursor to Post Traumatic Stress Disorder (PTSD). Recent data shows that the prevalence of ASD can range significantly depending on the nature of the traumatic event, with anywhere from 5% to 50% of trauma survivors experiencing it. Despite the short-term nature of ASD, the distress it causes is very real. Early identification and intervention can have long-term positive implications, potentially preventing the onset of PTSD and aiding in a more immediate return to regular function.

Symptoms of Acute Stress Disorder

If you suspect you or someone else is experiencing Acute Stress Disorder, it is crucial to seek immediate medical attention by calling emergency services or consult with a Psychologist.


The fundamental cause of ASD is a traumatic event. The brain has its own protective mechanisms. However, certain events can overload these mechanisms, leading to intense reactions. The events that can trigger ASD range from natural calamities like earthquakes and floods to man-made disasters like accidents, assaults, or witnessing violence, death, or severe injury, or even severe emotional stress. The event itself, combined with an individual's personal perception and interpretation of it, is at the heart of ASD's etiology.

Risk Factors

The development of ASD doesn't solely rest on the traumatic event. Multiple intertwining factors play a role:

• Personal History: Prior encounters with trauma or mental health disorders can prime an individual to be more reactive to new traumas.

• Nature and Duration of Trauma: Extended or extreme traumas generally lead to more pronounced reactions. •

 Existing Mental Health Disorders: Pre-existing anxiety or mood disorders can exacerbate the trauma response.

• External Support Systems: A robust support system acts as a buffer, whereas its absence can increase vulnerability.

• Complications: The most notable is the potential transition to PTSD.

However, prolonged untreated ASD can also lead to other complications like depression, anxiety disorders, substance abuse, and even physical ailments due to prolonged stress.


ASD presents an array of symptoms, many of which can be highly distressing:

• Dissociative Symptoms: These can range from feeling like things are unreal, to feeling detached from oneself or one's environment.

• Intrusive Recollections: This isn't just about remembering the event; it's about it bursting into one's consciousness, disrupting daily life.

• Avoidance Behaviour: This could be avoiding locations, people, or any other reminders of the traumatic event.

• Hyperarousal: Manifested as sleep issues, an exaggerated startle response, irritability, and difficulty concentrating.

Diagnosing ASD demands a thorough approach:

• A meticulous clinical interview is paramount. Here, the clinician will map symptoms against the criteria established by the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders)

• Considering the temporal nature of ASD, ensuring symptoms have manifested for a minimum of 3 days but not exceeding 4 weeks is crucial.

• Differential diagnosis plays a role.

The clinician must exclude other disorders or medical conditions that might be causing or exacerbating the symptoms.


Managing Acute Stress Disorder involves a multi-faceted approach that takes into consideration the unique experiences, needs, and preferences of the affected individual. Here’s an in-depth view of the available treatments:

1. Cognitive Behavioural Therapy (CBT):

• Overview: CBT is the most commonly recommended therapeutic intervention for ASD. It involves recognizing negative thought patterns and developing healthier coping mechanisms to deal with distress.

• Exposure Therapy: As a component of CBT, exposure therapy helps patients confront and control their fear by exposing them to the trauma they experienced in a controlled environment. This helps in reducing the intensity and influence of traumatic memories.

Cognitive Restructuring: This technique helps individuals make sense of the traumatic event. It aids in changing unhelpful or distorted thought patterns related to the trauma.

2. Eye Movement Desensitization and Reprocessing (EMDR):

• Overview: EMDR is a unique therapeutic method that involves processing distressing memories of a traumatic event. It combines structured therapies with a patient's spontaneous cognitive and emotional processes.

• Procedure: The process involves focusing on traumatic memories while making specific eye movements, typically guided by a therapist's fingers. This bilateral stimulation can help in reducing the emotional charge of traumatic memories.

3. Medication:

• Overview: While no drug is specifically approved to treat ASD, some medications can help alleviate its symptoms or address co-occurring issues.

• Selective Serotonin Reuptake Inhibitors (SSRIs): These are antidepressants that can help relieve symptoms of depression and anxiety, which often accompany ASD.

• Benzodiazepines: These sedatives can help with anxiety and sleep problems. However, they are not typically used as a first-line treatment due to concerns about dependency and potential side effects. 

• Beta Blockers: Some beta-blockers, which are used to treat high blood pressure, might help reduce the physical symptoms or intense emotional reactions associated with traumatic memories. 

4. Group Therapy:

• Overview: Sharing traumatic experiences in a safe, supportive environment can be therapeutic for some individuals. Group therapy provides a platform for mutual support and understanding.

• Benefits: Group members can offer feedback, validation, and coping techniques, all while fostering a sense of belonging. 5. Psychodynamic Therapy: • Overview: This approach involves exploring past experiences and emotional conflicts to understand current feelings and behaviors. 

• Objective: Psychodynamic therapy aims to increase the patient’s self-awareness and understanding of their behavior's influence, promoting personal growth and symptom resolution.

6. Relaxation Techniques:

• Overview: Techniques such as deep breathing exercises, progressive muscle relaxation, and meditation can help alleviate symptoms of anxiety and improve overall well-being.

• Application: Regular practice can serve as a means to regulate stress responses, grounding the individual during moments of heightened distress.

7. Support from Loved Ones:

• Overview: Encouragement and understanding from family and friends can be instrumental during the healing process.

• Benefits: A robust support system provides emotional stability, and perspective, and often helps in facilitating early intervention and continued treatment adherence. Early intervention and a tailored combination of the above treatments can significantly improve the outcome for individuals experiencing ASD and can potentially prevent the progression to more chronic conditions like PTSD.

Preventive Measures

While not all traumatic events can be predicted or prevented, there are steps to foster resilience:

• Building a Support System: Cultivating strong, supportive relationships can act as a buffer against the adverse effects of trauma.

• Develop Coping Skills: Engaging in mindfulness practices, relaxation techniques, and other coping strategies can help.

• Stay Informed: Understanding potential risks in one's environment and having a plan can make a difference.
