Clinical Trial Summary

Post-Traumatic Stress Disorder (PTSD) is a public health problem due to both its chronic nature and the low response rate to conventional therapies.

Sleep disorders are the first cause of complaint in patients with PTSD due to night awakenings, difficulty to fall asleep and nightmares.

According to a part of the scientific community, replicative traumatic nightmares represent PTSD's basis mechanism. Traumatic nightmares generate disabling symptoms such as anxiety reactions, while maintaining the symptoms by depriving the individual of good quality sleep. Traumatic nightmares may thus be a sign of PTSD seriousness and chronicity, although their physiological basis remain poorly known.

In the military population, which is highly exposed to psychological traumatism, PTSD prevalence is very high and is associated with severe intensity patterns, a very high frequency of replicative nightmares and a low response to conventional therapies.

Sleep is recorded at home during 7 nights in a row using a connected headband. The participant also has to fill in a sleep agenda every day.
• Cognitive tasks
Working memory and inhibition capacity is assessed during computer-based tasks (2-back and Go/No-Go tasks) at enrollment and 1 month after enrollment.

Other:
• Questionnaires
The participant has to fill in several questionnaires at enrollment and 1 month after enrollment in order to assess: PTSD severity chronotype Sleep quality Daytime sleepiness Mood state Depression Mental disorders and their consequences

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of subjects with a Sleep Efficiency Index (SEI) < 80%.	The sleep efficiency index (SEI) is defined by the ratio TST/TIB with TST being Total Sleep Time and TIB being Time In Bed.; TST and TIB will be assessed objectively, at home, using a connected headband (DREEM®, Rythm Paris).; A Sleep Efficiency Index (SEI) < 80% is considered to be a poor quality, low-efficiency night.	1 month after enrollment
