Trauma

WHAT IS TRAUMA?

 

Trauma refers to an event that threatens the life or integrity of the individual or a loved one, such as physical abuse, death of a parent, witnessing domestic violence, abandonment, natural disasters, war, community violence, or medical issues. Types of traumas include single, complex, developmental, historical and intergenerational.

Trauma affects brain development, causing structural and hormonal changes that manifest in adverse physical and mental outcomes. If exposure to stress and trauma is unrelenting, the brain adapts in ways that can make learning and socialization difficult. Persistent exposure to toxic stress during childhood can have serious developmental consequences that may last well past the time of stress exposure. 

WHY IS IT IMPORTANT?

Psychological trauma is a major public health issue affecting the health of people, families and communities across Canada. Trauma places an enormous burden on every health care and human service system. Trauma is not only a mental health issue, but it also belongs to every health sector, including primary/ physical, mental and spiritual health. Given the enormous influence that trauma has on health outcomes, it is important that every health care and human services provider has a basic understanding of trauma, can recognize the symptoms of trauma, and appreciates the role they play in supporting recovery. Health care, human services and, most importantly, the people who receive these services benefit from trauma- informed approaches. 

WHAT DOES IT LOOK LIKE?

Reactions to trauma vary from person to person, from minor disruptions in an individual’s life to debilitating responses. Across the continuum, people may experience anxiety, terror, shock, shame, emotional numbness, disconnection, intrusive thoughts, helplessness and powerlessness. Trauma responses can interfere with an individual’s sense of safety, self, and self-efficacy, as well as the ability to regulate emotions and navigate relationships.

Physiological adaptations can create an underlying state of dysregulation – difficulty controlling or regulating emotional reactions or behaviours and/or an imbalance in the body, which often results in hyperarousal and hypervigilance (in which an individual seems to overreact to every situation) or listlessness and dissociation (in which an individual seems numb and disconnected in stressful or dangerous situations). This dysregulation of the brain and body systems perpetuates mental, emotional, and physical distress.
