Acute Stress Disorder (ASD) is a psychological condition that occurs after experiencing or witnessing a traumatic event. It can affect a person's thoughts, emotions, and behaviour, often causing intense distress and difficulty in daily life. ASD usually develops shortly after the traumatic incident and may last for a short period if properly managed.

What Are the Types of Acute Stress Disorder?

Acute Stress Disorder is generally not divided into formal subtypes. However, symptoms can appear in different categories depending on how the trauma affects an individual.

Intrusion symptoms involving flashbacks, nightmares, or distressing memories
Avoidance symptoms, where individuals try to avoid reminders of the traumatic event
Dissociative symptoms, such as feeling detached from reality or surroundings
Negative mood symptoms, including persistent fear, sadness, or emotional numbness
Arousal symptoms such as irritability, sleep disturbances, or difficulty concentrating

What Are the Symptoms of Acute Stress Disorder?

Acute Stress Disorder can cause a range of emotional, mental, and physical symptoms after a traumatic experience. These symptoms can interfere with daily life and may appear within days of the event.

Intrusive memories, flashbacks, or nightmares related to the traumatic event
Repeated distressing thoughts about the event
Avoiding people, places, or situations that remind the person of the trauma
Emotional numbness or difficulty experiencing positive emotions
Feeling detached from others or socially withdrawn
Increased irritability, anxiety, or difficulty concentrating
Sleep disturbances or frequent waking during the night
Exaggerated startle response or constant alertness
Dissociation, including feeling disconnected from thoughts or surroundings
Depersonalization, where individuals feel detached from their own body or identity

What Causes Acute Stress Disorder?

Acute Stress Disorder develops after exposure to a traumatic or life-threatening situation. The intensity of the event and an individual's ability to cope with stress can influence the development of the disorder.

Experiencing serious accidents or injuries
Exposure to natural disasters such as earthquakes, floods, or storms
Witnessing violence, assault, or other traumatic incidents
Life-threatening situations affecting oneself or others
Previous exposure to traumatic experiences
Personal vulnerability or limited coping mechanisms

Severe anxiety, fear, or emotional numbness
Difficulty sleeping or concentrating
Avoidance of daily activities or social withdrawal
Symptoms lasting for several days or worsening over time
