Life Sciences—Life Writing: PTSD as a Transdisciplinary Entity between Biomedical Explanation and Lived Experience

Abstract

Abstract:Since the second half of the 20th century, the life sciences have become one of the dominant explanatory models for almost every aspect of human life. Hand in hand with biomedical developments and technologies, the life sciences are constantly shaping and reshaping human lives and changing human biographies in manifold ways. The orientation towards life sciences and biomedicine from the very beginning to the end of human life is driven by the utopian notion that all forms of contingency could be technologically and medically controlled. This paper addresses the interrelatedness of life sciences and human biographies in a field where contingency and risk become essential and existential parts of lived experience: post-traumatic stress disorder (PTSD). On the one hand, this diagnostic entity is related to (neuro-)biological underpinnings of (a lack of) psychic resilience as well as to those of contemporary pharmacotherapy. On the other hand, PTSD is also understood as based on a traumatic life event, which can be accessed through and addressed by talk therapy, particularly narrative exposure therapy (NET). We argue that a novel focus on concepts of narrativity will generate pathways for an interdisciplinary understanding of PTSD by linking biological underpinnings from neurobiological findings, to brain metabolism and pharmacotherapy via the interface of psychotherapy and the specific role of narratives to the lived experience of patients and vice versa. The goal of our study is to demonstrate why therapies such as psychotherapy or pharmacotherapy are successful in controlling the disease burden of PTSD to some extent, but the restitutio ad integrum, the reestablishing of the bodily and psychic integrity remains out of reach for most PTSD patients. As a test case, we discuss the complementary methods of Traditional Chinese Medicine (TCM) and the established procedures of talk therapy (NET) to show how a methodological focus on narratives enhanced by notions of narrativity from the humanities grants access to therapeutically meaningful, enriched notions of PTSD. We focus on TCM because trauma therapy has long since become an intrinsic part of this complementary medical concept which are more widely accessible and accepted than other complementary medical practices, such as Ayurveda or homeopathy. Looking at the individual that suffers from a traumatic life event and also acknowledging the contemporary concepts of resilience, transdisciplinary concepts become particularly relevant for the medical treatment of and social reintegration of patients such as war veterans. We emphasize the necessity of a new dialogue between the life sciences and the humanities by introducing the concepts of corporeality, capability and temporality as boundary objects crucial for both the biomedical explanation, the narrative understanding and the lived experience of trauma.

The Meaning of Literature and Literature as Meaning—A Productive Challenge of Modern Times from the Middle Ages

“…As we have learned from trauma studies, for instance, narrations are superbly qualified as therapeutic methods especially in such troublesome cases [91]. Racism and intolerance can be similarly combated by means of storytelling, as Boccaccio already indicated with his example, even if problematic as some modern scholars have viewed it from their perspective [92][93][94][95].…”

“Life Is So Good”: Centenarians’ Autobiographies Between the Promise of Immortality and the Specter of Death

“…Central to this idea of living a well-lived life is the concept of resilience. It is significant here that at this point, there is a clear overlap between centenarians' autobiographies and studies in the life sciences about centenarians' lifestyles (Paul et al, 2015). These latter studies have investigated the concept of resilience.…”

Health(care) in the Crisis: Reflections in Science and Society on Opioid Addiction

“…In the final part of this paper, current avenues for treatment will be examined. In the conclusion, we explore the potential advantages and challenges of an interdisciplinary approach, which combines the life sciences and the humanities [ 4 ] and we suggest that without such interdisciplinarity, we may fail to grasp the current opioid crisis in all its complexity. Finally, while this article discusses the opioid crisis in the U.S. specifically, it also has worldwide implications for the use of opioid-based pain medication.…”
