Impact of Prolonged Collective Trauma and PTSD on Mental Health
Prolonged collective trauma leaves a lasting mental health footprint, as outlined in a review published by News-Medical and information from the Australian Institute of Health and Welfare (AIHW).
- Stress can initiate the ‘fight or flight’ response, a complex reaction of the neurologic and endocrine systems.
- Differentiating stress from trauma remains challenging due to the complexity of events and variation in individual responses.
- People who survive traumatic injuries frequently endure long-lasting physical, emotional, cognitive, and financial repercussions that impact them, their households, and the broader community.
Distinguishing Stress Pathologies from Traumatic Injury
According to the AIHW, citing NIMH 2019 and Stöppler 2018, stress initiates a complex reaction of the neurologic and endocrine systems. Prolonged or intense stress can trigger various physical manifestations like headaches, diminished appetite, elevated blood pressure, chest discomfort, sexual difficulties, and trouble sleeping, even though stress itself is a typical and expected bodily reaction to unfamiliar or demanding circumstances.
The AIHW distinguishes standard stress responses—triggered by events like job loss, exams, deadlines, finances, or divorce—from trauma involving exposure to actual or threatened death, serious injury, or sexual violence. Traumatic exposures can precipitate post-traumatic stress disorder (PTSD), a condition diagnosed when fear, anxiety and memories of a traumatic event persist. Data from Phoenix Australia 2019, cited by the AIHW, indicate that unexpected death of a close loved one, witnessing a person critically injured or killed, or finding a body, and being in a life-threatening car accident are the most common traumatic events for Australians.
Epidemiological Complexities in National Health Surveys
Quantifying the societal burden of stress and trauma presents significant methodological hurdles for researchers. The Australian Bureau of Statistics incorporates measures of stress into major data collection instruments, including the National Health Survey and the General Social Survey. Despite these population-wide assessments, tracking individual clinical trajectories remains difficult due to the complexity of events and variation in individual responses.
According to the AIHW, exposure to trauma may play a role in fostering various psychological conditions, including anxiety and depressive disorders, substance and alcohol use issues, alongside self-harm and suicide-associated actions. Furthermore, childhood trauma experiences increase the risk of developing mental illness and affect clinical course and responses to treatment.
