Understanding Post-Traumatic Stress Disorder: A Growing Concern in Australia
Post-traumatic stress disorder (PTSD), a condition characterized by a collection of symptoms following a traumatic experience, is a significant mental health concern in Australia. Experts from institutions including the University of the Sunshine Coast (UniSC) and the University of Adelaide have outlined its symptoms, diagnostic timelines, prevalence, and various treatment options, including established therapies and new approaches like Reconsolidation Therapy.
What is Post-Traumatic Stress Disorder?
PTSD is defined as a series of symptoms that can emerge after an individual has been exposed to or has witnessed a life-threatening event.
"Professor Alain Brunet, director of the National PTSD Research Centre at UniSC’s Thompson Institute, notes that traumatic memories associated with PTSD often retain their vividness over time, presenting as intense emotions, sounds, and smells, rather than as a verbal narrative."
Common symptoms of PTSD include:
- Re-experiencing the trauma through unwanted thoughts, nightmares, and flashbacks.
- Avoiding reminders of the event, such as specific places, people, or conversations.
- Difficulty concentrating and startling easily.
- Emotional withdrawal and negative changes in thoughts and mood.
- Hypervigilance, feeling "on edge," or experiencing an overly aroused "fight or flight" response.
Prevalence and Causes
PTSD is a widely diagnosed mental health condition in Australia, affecting approximately one in every 20 people annually. The rate of PTSD diagnoses is reported to be increasing, with connections to events such as floods, bushfires, other climate change-related weather phenomena, and various specific incidents.
Prominent causes in civilian communities include interpersonal violence, sexual assault, motor vehicle accidents, and large-scale natural disasters.
Diagnosis and Seeking Support
While normal stress reactions can follow a traumatic event, individuals are advised to consider seeking professional support if symptoms persist for several weeks or more than 30 days. The National PTSD Research Centre provides a free pre-diagnostic screening tool online to help individuals assess their likelihood of having PTSD. However, a formal diagnosis must be provided by a qualified health professional, such as a general practitioner.
"Professor Brunet highlights the importance of addressing the stigma associated with seeking mental health support."
One individual, identified as Louise, received a PTSD diagnosis five years after experiencing symptoms like depression and recurring nightmares following a domestic violence incident. Her initial diagnosis was later revised by new mental health professionals. Louise reported positive outcomes from her subsequent therapy, including an absence of nightmares, improved sleep, and improved relationships.
Treatment Approaches
Several established treatments are recommended for PTSD:
- Cognitive Behavioural Therapy (CBT)
- Cognitive Processing Therapy (CPT)
- Eye Movement Desensitisation and Reprocessing (EMDR)
These therapies often focus on helping individuals re-engage with trauma memories to facilitate their conversion into verbal representations. Standard antidepressants may also be prescribed to reduce emotional reactivity, which can aid the trauma processing.
Reconsolidation Therapy
Professor Alain Brunet has developed Reconsolidation Therapy, a new treatment currently undergoing clinical trials at the National PTSD Research Centre. This therapy utilizes medication to assist the brain in processing and updating trauma-related memories.
"Studies on this treatment have indicated that between 70% and 84% of participants reported symptom improvement after a course of six 25-minute therapy sessions."
Reconsolidation Therapy has also been implemented for clinicians addressing war-related trauma in Ukraine.
Experimental Treatments
While effective treatments for PTSD exist, caution is advised regarding experimental approaches such as microdosing psychedelics. Experts emphasize the need for robust research to support the widespread use and demonstrate the cost-effectiveness of such treatments.
Research and Resources
The National PTSD Research Centre, situated at UniSC’s Thompson Institute, conducts research, clinical trials, and community outreach initiatives. The centre also provides resources for individuals experiencing trauma and is actively involved in clinical trials for Reconsolidation Therapy.
