Cumulative trauma, neural circuits, and burnout: an integrative model of healthcare worker post-traumatic stress syndromes
How repeated trauma and brain circuit changes relate to burnout and stress symptoms in healthcare workers
AI simplified
Abstract
prevalence among healthcare workers is variable, ranging from 15-74%.
- Repeated, chronic, and unpredictable occupational trauma can disrupt brain circuits involved in emotional regulation and stress response.
- Circadian rhythm disruption, common in shift work, may contribute to heightened stress and exacerbate the risk of post-traumatic stress syndromes.
- Multimodal biomarkers, including brain imaging and physiological measures, could help identify early dysregulation and assess risk for PTSS.
- There is a need for longitudinal studies to monitor the progression of PTSS and evaluate targeted treatment approaches.
- Conceptualizing HCW PTSS as an occupational neurobiological injury emphasizes the importance of prevention and intervention strategies.
