Sleep and trauma: an overview.

Sleep disturbance is common after traumatic events of various types, such as combat, physical trauma, and sexual abuse, and closely intertwined with Posttraumatic Stress Disorder (PTSD), a common outcome of severe and prolonged trauma. This paper reviews the current literature on the significance and characteristics of sleep disturbance occurring in the context of trauma, examines the relationship between sleep disturbance and PTSD, identifies gaps in knowledge relative to the role of sleep disturbance in trauma and PTSD, and discusses the implications of this body of knowledge for clinical practice.
