Introduction to the special section on the long‐term health impact of trauma, posttraumatic stress disorder, comorbid conditions, and aging

This article introduces a special section of the Journal of Traumatic Stress devoted to new research investigating and addressing the associations among trauma exposure, posttraumatic stress disorder (PTSD), comorbid conditions, and aging. As the global population is rapidly aging, it is critical to advance understanding of the long-term health implications of trauma, PTSD, and comorbid conditions, including impacts on health, functioning, and well-being across the life course. In addition to understanding these trauma-related risks in varying populations, it is important to evaluate potential sources of resilience as well as to consider implications for health care services, including trauma-informed care, in the context of aging. This opening article introduces themes reflected in this collection of new scientific manuscripts examining a range of relevant questions and populations, which collectively contribute to this important and growing area of research in the traumatic stress field.
