Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to examine sleep architecture in refugees with PTSD. Polysomnography (PSG) will be carried out to study the occurrence of sleep disorders in patients and healthy controls.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

There is little knowledge on treatment of sleep disturbances in trauma-affected refugees and this study will be the first to record the biophysiological changes that occur during sleep in refugees with PTSD. The study is a proof-of-concept study and this will contribute with new and potentially crucial knowledge of sleep disturbances in these patients.

The project is designed as a cross-sectional study with 20 refugees with PTSD referred to the specialised outpatient clinic, Competence Centre for Transcultural Psychiatry (CTP), and 20 healthy control subjects.

All patients referred to CTP will be invited to an initial consultation with a doctor. During this consultation a diagnostic assessment will be performed and the clinical history will be obtained. Patients who give informed consent will be invited to participate in the project and have sleep measurements performed by PSG. Furthermore self-administered questionnaires and semi-structured interviews will be used to collect information on mental health, sleep quality, sleep length and nightmares.

Each patient will be equipped with PSG equipment to do measurements at home for one night (12 hours). Healthy control subjects will fill out the same CTP standard ratings and have the same diagnostic assessment and PSG measurement.

The hypothesis is that the sleep architecture in refugees with PTSD differ from healthy controls. It is suggested that refugees with PTSD have increased dream activity as well as increased incidence of sleep disorders such as rapid eye movement (REM) sleep without atonia (RSWA), REM sleep behaviour disorder (RBD), sleep apnea and periodic limb movement disorder (PLM).

The study is performed in collaboration with Danish Centre for Sleep Medicine in Denmark.
