Stress is a word in common usage in our society, and is usually caused when we are feeling overwhelmed by home responsibilities, work roles, parenting, studies … the list goes on.
Acute Stress Disorder (ASD) however has a very different meaning.
It is a condition which may develop following a trauma/traumatic event, and may also be referred to as “acute stress reaction”, “psychological shock”, or just “shock”.
The Definition of Trauma
There are various definitions of the word “trauma”. When used by medical professionals, it describes a physical ailment or injury; however in the mental health field it is used to refer to a particular event, or at other times, the psychological injury resulting from such an event.
Psychological injury (trauma) may occur when a person experiences, witnesses, or is confronted by, a traumatic event that includes some form of serious physical threat – for example, natural disasters such as flood or fire; sexual assault; physical assault; serious accidents; war and military conflict; etc.
It may be a one-off event, or something that has occurred numerous times. Regardless, the traumatic event generates overwhelming feelings of horror, terror or helplessness in the individual.
Obviously, exposure to trauma can cause significant distress, and have an immediate negative impact on the individual’s day to day functioning. However the majority of people are able to recover quite quickly, and do not go on to develop Acute Stress Disorder, or Post Traumatic Stress Disorder (PTSD).
How is Acute Stress Disorder different to PTSD?
Acute Stress Disorder and Post Traumatic Stress Disorder are very closely related: both can result when an individual has been exposed to some form of traumatic event; and they share similar symptoms.
The key difference is in the duration of the condition. Acute Stress Disorder occurs between 2 days and 1 month after the trauma; while a diagnosis of PTSD can only be made if the symptoms occur and/or persist over a month later.
Symptoms of Acute Stress Disorder
There are a number of symptoms which must be present before a diagnosis of Acute Stress Disorder can be made. These may include:
- Upsetting memories, flashbacks and nightmares.
- Feeling of numbness, being in a daze, or being unable to recall important aspects of the traumatic event.
- Avoiding people, places, activities or objects that may trigger memories, thoughts, or feelings about the traumatic event.
- Exhibiting signs of arousal such as difficulties sleeping, irritability, being constantly alert and on-edge, or easily startled.
Research demonstrates that the therapeutic alliance between the individual and their mental health professional is of critical importance to effective treatment for ASD/PTSD. Developing that alliance and rapport can obviously be much more challenging where trauma has taken the form of sexual assault or torture, and requires warmth and empathy as well as the expert skills of the practitioner.
Treatment aims to reduce both the symptoms, and their severity. Working together with you, your psychologist may formulate a treatment plan drawing from evidence-based therapies such as Cognitive Behaviour Therapy (CBT), exposure therapy and cognitive therapy.
If you or a loved one is struggling following any form of trauma, I encourage you to seek professional help.
