Abstract:
Peri-traumatic sleep disturbances are growingly recognized as biologically-relevant and modifiable predisposing, precipitating, and perpetuating factors in posttraumatic stress disorder (PTSD). The exponential growth of the literature on sleep in PTSD over the last two decades has stimulated a paradigm shift in the conceptualization of the relationship between sleep and PTSD. A conceptual framework that captures this paradigm shift is offered. New research on existing and promising sleep-focused treatments for augmenting PTSD treatment outcomes is then summarized. New findings on the neurobiological correlates and underpinnings of the relationship between sleep and PTSD are also discussed. Informed by these recent findings and foundational literature, opportunities for innovation in clinical and experimental research are proposed.
