Sleep and Emotional Trauma: The PTSD Connection


By Staff Reports

(DGIwire) – To what extent does sleep help people process stress and trauma? A recent study by researchers in the Department of Psychology at the University of Zurich set out to address this question. As reported by PsychCentral, the investigators discovered that sleep—especially during the first 24 hours after a trauma—appears to play a key role in helping individuals manage the emotional impact of the event. This knowledge, notes PsychCentral, is highly relevant for experts focused on the prevention of post-traumatic stress disorder (PTSD). It also is important for developing improved treatments targeting sleep to relieve overall PTSD symptoms for those who already have PTSD.

As reported by PsychCentral, the Zurich researchers showed a group of individuals a traumatic video and instructed them to record in a diary their recurring memories of the film over the next few days, mimicking the flashbacks of trauma associated with PTSD. During the first 24 hours, the group was split into two: one subgroup slept in the lab for the night, with their sleep recorded via an electroencephalograph (EEG); the other subgroup remained awake. Those who slept after the video were found to have fewer and less-distressing recurring emotional memories than those who did not sleep. This supports the assumption that sleep may have a protective effect in the aftermath of traumatic experiences, the researchers reported.

Currently there are no satisfactory approved drug treatments for military-related PTSD. The investigational new drug used in the HONOR study represents a new approach to treating the condition. While symptoms of PTSD may improve or worsen while taking part in this study, participation will provide information about the study drug, a new approach to treating PTSD, that might benefit others with the condition in the future.
