NCT05953207

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 (N=60). 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 (EEG). Estimated duration: 2h.
  • 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 EEG 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. For the validation of the EEG methodology, healthy volunteers (N=50) will complete a unique visit resembling the initial study visit of patients.

Outcome Measures

Primary Outcomes (1)

  • Change, from pre-treatment, of mean number of parasomniac episodes at 9 weeks

    Parasomniac episodes scored on infrared home video recording

    Over a recording period of 10 consecutives nights, 2 weeks before (pre-treatment) and 3 weeks after (at 9 weeks) the treatment

Secondary Outcomes (21)

  • 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

  • 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

  • Incidence of emotions related to parasomniac episodes

    Through study duration, an average of 9 weeks

  • Quality of life score

    At Day 0, Week 11 and Week 18

  • Anxiety and depression scores

    At Day 0 and Week 11

  • +16 more secondary outcomes
