The Neuroplastic Narrative and Neuro-Ecological Diversity: Non-Pathologizing Biological Foundations for Trauma-Informed Medical and Mental Health Nursing.

Following the Adverse Childhood Experiences study (1998), a wealth of similar studies has strongly associated experiences of trauma and adversity in childhood with increased risk of poor physical and mental health and undesirable social outcomes in adulthood. The medical model interprets this data through a pathologizing lens which assumes that trauma and adversity are harmful and lead to impairment and pathology. Trauma-informed and Adverse Childhood Experience aware approaches can perpetuate this pathologizing framing, despite prioritising asking "What's happened to you?" over "What's wrong with you?" In this paper, we draw on The Neuroplastic Narrative, a novel, non-pathologizing biological theory which foregrounds people's adaptation to their ecological niche. This narrative offers a compelling reinterpretation of data that associates early trauma and adversity with poor adult health and social outcomes. We introduce an evolutionary perspective, Life History Theory, to reframe the Adverse Childhood Experiences (ACEs) study through an evolutionary lens, yielding the insight that populations with ACEs strategically adapt to their environment. We evidence the perspective that the human species' capacity to adapt to a diverse range of environments during development is strategic and not of itself pathological. Adapting to diverse ecologies produces commensurately diverse brains and physiologies. We term the diversity across brains and physiologies resulting from adapting to experiences: Neuro-ecological diversity An ecological framing that privileges experiences and considers how and why people adapt to traumatising relationships and adverse environments both physiologically and behaviourally calls for novel formulations and responses from practitioners and ultimately for a non-pathologizing foundation for trauma-informed nursing. This less shaming response also orientates our attention towards issues of inequity and social justice. The aim of this position paper is to articulate a trauma-informed framework for nursing that does not focus on pathology but rather on adaptation, offering nurses a new way to understand, formulate and respond to distress and suffering associated with trauma and adversity. We will demonstrate that trauma-informed nursing needs a foundation that is not premised in pathology but honours experience; offer the Neuroplastic Narrative as a biological, non-pathologizing (less shaming) foundation for trauma informed nursing, and introduce the concept of Neuro-Ecological Diversity to support nurses' understandings of, and responses to, different consumer presentations.
