Non-pharmacological Treatments for Parasomnias
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to compare the efficacy of non-pharmacological treatments (medical hypnosis and standard treatment) in patients with a non-REM parasomnia diagnosis.
Participants are randomly assigned to one of the two treatments. Treatment consists of 3 sessions. Participants receiving the standard treatment (i.e., sleep hygiene and episode risk reduction) may subsequently receive medical hypnosis.
Participation in the study involves 5 visits in total: 3 treatment visits and 2 study visits to the hospital (CHUV).
-
An initial study visit to provide information and collect questionnaires prior to the start of treatment. An initial non-therapeutic hypnosis session will be carried out during electroencephalography. Estimated duration: 1h30.
-
A second study visit at the end of treatment, including questionnaires about your sleep and treatment. A shorter non-therapeutic hypnosis session and a second electroencephalography will be performed. Estimated duration: 1h30. This visit may also be followed by an overnight polysomnography, according to patient's choice (if performed, estimated total duration 12 hrs).
This study also involves monitoring patients' sleep for 10 nights before and after treatment:
they will fill in a sleep diary and use an infrared camera.

Outcome Measures
Primary Outcome Measures
- Change, from pre-treatment, of mean number of parasomniac episodes at 9 weeks [Over a recording period of 10 consecutives nights, 2 weeks before (pre-treatment) and 3 weeks after (at 9 weeks) the treatment]
Parasomniac episodes scored on infrared home video recording
Secondary Outcome Measures
- Duration of parasomniac episodes [Over a recording period of 10 consecutives nights, 2 weeks before (pre-treatment) and 3 weeks after (at Week 9) treatment]
Using home video recording
- Rate of confusional arousals, sleepwalking and sleep terrors episodes [Over a recording period of 10 consecutives nights, 2 weeks before (pre-treatment) and 3 weeks after (at Week 9) the treatment]
Categorization of parasomniac episodes' complexity (confusional arousals, sleepwalking, sleep terrors) using home video recording
- Incidence of emotions related to parasomniac episodes [Through study duration, an average of 9 weeks]
Emotional impact of parasomniac episodes using questionnaires (e.g., What emotions did you feel during these episodes?; Do you have negative emotions related to your parasomnias?)
- Quality of life score [At Day 0, Week 11 and Week 18]
Using a standardized questionnaire: World Health Organization Quality Of Life-BREF (WHOQOL-BREF). Score ranging from 0 to 100, higher score denoting greater perceived quality of life.
- Anxiety and depression scores [At Day 0 and Week 11]
Using a standardized questionnaire: Hospital Anxiety and Depression Scale (HADS). Subscale score ranging from 3 to 21, score >8 denotes anxiety or depression.
- Traumatic events score [At Day 0]
Using a standardized questionnaire: Life Event Checklist for DSM-5 (LEC-5). It does not yield a total score or a composite score.
- Fatigue score [At Week 2, Week 11 and Week 18]
Using a standardized questionnaire: Pichot's fatigue scale. Score ranging from 0 to 32, score >22 denotes excessive fatigue.
- Sleepiness score [At Week 2, Week 11 and Week 18]
Using a standardized questionnaire: Epworth Sleepiness Scale (ESS). Score ranging from 0 to 24, higher score denoting higher daytime sleepiness.
- Sleep quality score [At Week 2, Week 11 and Week 18]
Using a standardized questionnaire: Pittsburgh Sleep Quality Index (PSQI). Score ranging from 0 to 21, higher score denoting greater acute sleep disturbances.
- Severity of arousal disorders score [At Week 2, Week 11 and Week 18]
Using a standardized questionnaire: Paris Arousal Disorders Severity Scale (PADSS). Score ranging from 0 to 50, higher score denoting more severed disorders.
- Circadian typology score [At Week 2, Week 11 and Week 18]
Using a standardized questionnaire: Horne & Östberg questionnaire. Score ranging from 16 to 86, higher score denoting morningness and lower score eveningness.
- Changes in imagery processes [At Day 0 and Week 11]
Using power spectral sleep EEG analysis including delta (1-4 Hz), theta (4-8 Hz), alpha (8-12 Hz), sigma (12-16 Hz), and beta (18-30 Hz) frequency bands with Titanium, Embla®, NOX-A1®.
- Sleep eye movements [At Week 11 (optional)]
Using power spectral sleep EOG analysis (left and right) with Titanium, Embla®, NOX-A1®.
- Sleep muscles activity [At Week 11 (optional)]
Using power spectral sleep EMG analysis (chin and anterior tibialis muscle) with Titanium, Embla®, NOX-A1®
- Sleep cardiac activity [At Week 11 (optional)]
Using power spectral sleep ECG analysis (P wave, QRS complex, QT interval, PR interval...) with Titanium, Embla®, NOX-A1®.
- Sleep oxygen saturation [At Week 11 (optional)]
Using sleep oxygen saturation measures with Titanium, Embla®, NOX-A1®.
- Sleep airflow [At Week 11 (optional)]
Using sleep airflow measures with Titanium, Embla®, NOX-A1®.
- Sleep respiratory efforts [At Week 11 (optional)]
Using abdominal and thoracic respiratory efforts measures with Titanium, Embla®, NOX-A1®.
- Snoring [At Week 11 (optional)]
Using snoring measures with Titanium, Embla®, NOX-A1®.
