Acute Stress Disorder (ASD)

Acute Stress Disorder is a psychological condition that can develop shortly after exposure to a traumatic event, characterized by severe anxiety, dissociation, and other symptoms lasting between 3 days to 1 month. If symptoms persist beyond a month, it may develop into Post-Traumatic Stress Disorder (PTSD).

Key Features of ASD

1. Triggering Event

ASD occurs after exposure to a traumatic event involving:

  • Actual or threatened death
  • Serious injury
  • Sexual violence
  • Witnessing or experiencing extreme trauma

2. Symptoms (Lasting 3 Days to 1 Month)

Symptoms fall into five categories:

A. Intrusion Symptoms

  • Recurrent, involuntary distressing memories
  • Flashbacks or nightmares
  • Intense distress when reminded of the trauma

B. Negative Mood

  • Persistent inability to experience positive emotions

C. Dissociative Symptoms

  • Feeling detached from oneself (depersonalization)
  • Feeling the world is unreal (derealization)
  • Inability to remember parts of the trauma (dissociative amnesia)

D. Avoidance Symptoms

  • Avoiding thoughts, feelings, or reminders of the trauma

E. Arousal Symptoms

  • Sleep disturbances
  • Irritability or aggression
  • Hypervigilance
  • Difficulty concentrating
  • Exaggerated startle response

Diagnosis (Based on DSM-5 Criteria)

  • Symptoms must last 3 days to 1 month after trauma.
  • Cause significant distress or impairment in daily functioning.
  • Not due to substance use, medical conditions, or other mental disorders.

Treatment Options

  1. Psychological Therapies
    • Trauma-Focused Cognitive Behavioral Therapy (CBT) – Helps process trauma and reduce avoidance.
    • Exposure Therapy – Gradual, controlled exposure to trauma reminders.
    • Mindfulness & Grounding Techniques – Helps manage dissociation.
  2. Medications (Short-term, if severe)
    • SSRIs (e.g., sertraline) for anxiety/depression.
    • Short-term benzodiazepines (rarely, due to dependency risk).
  3. Support & Early Intervention
    • Psychoeducation about trauma responses.
    • Social support from family, friends, or support groups.

Difference Between ASD and PTSD

FeatureASDPTSD
Duration3 days – 1 month>1 month
DissociationMore prominentMay or may not be present
OnsetImmediate (within days)Can be delayed (months later)

Prognosis

  • Many recover with early intervention.
  • About 50% of ASD cases progress to PTSD if untreated.
  • Strong social support reduces risk of long-term effects.

If you or someone you know is experiencing ASD symptoms, seeking professional mental health support early can improve recovery outcomes.
