Indução de sonhos com EEG e anestesia para transtorno de estresse pós-traumático (IDEA_PTSD)

29 de setembro de 2026 atualizado por: Boris D. Heifets, Stanford University

Eficácia do sonho induzido por anestesia para transtorno de estresse pós-traumático: um ensaio clínico randomizado

The goal of this study is to test whether anesthesia-induced experiences can help alleviate symptoms of PTSD in an (1) open-label trial (Phase I) and (2) single-center double-blind, randomized, active-comparator (dose-controlled) participant-and assessor-blinded Phase 2 clinical trial (Phase II) in a non-surgical setting. Participants will undergo EEG-guided propofol anesthesia during which they will be either (1) receiving a sedation protocol associated with dream experiences upon emergence (Dream Condition), and/or (2) a sedation protocol associated with non-dream experiences (Non-Dream Condition). The investigators will then investigate whether the Dream Condition is associated with a larger reduction in PTSD symptoms than the Non-Dream Condition.

Descrição detalhada

GENERAL BACKGROUND

Post-traumatic stress disorder (PTSD) affects millions of Americans, and it can make everyday life very challenging. PTSD is characterized by recurrent distressing memories and nightmares, flashbacks, hyperarousal, and avoidance of things that remind individuals of their traumatic event. Nightmares reflect impaired emotion regulation occurring during sleep. There is evidence that therapeutic applications of dreaming may help target nightmares and other PTSD symptoms because dreaming is involved in memory (re)processing and emotion regulation. There is preliminary evidence that dreaming during anesthesia may reduce symptoms of PTSD. However, larger studies are needed to systematically test this.

AIM AND HYPOTHESES

The aim of this study is to test the efficacy of anesthesia-induced dreaming for PTSD in a (1) open-label trial (Phase I) and (2) a single-center double-blind, randomized, active-comparator (dose-controlled) participant-and assessor-blinded clinical trial (Phase II) in a non-surgical setting. The investigators predict that inducing and sustaining a dream state prior to emergence from anesthesia will result in reduced symptoms of PTSD.

STUDY DESIGN

Design:

Phase I : Open-label study Phase II: Double-blind, randomized, active-comparator (dose-controlled) participant-and assessor-blinded Phase 2 clinical trial (RCT)

Sample Size:

Phase I: N = 15 Phase II: N = 42 (21 in Dream Condition, 21 in Non-Dream Condition)

Variables:

Phase I and II: Outcome variables include: (1) Clinician-Administered PTSD Scale for DSM-5 (CAPS-5); (2) PTSD Checklist for DSM-5 (PCL-5)

STUDY PROCEDURES AND MEASURES

This research study is expected to take approximately four months to complete (per participant). During this time, participants will make two pre-screening visits via Zoom as well as one screening visit via Zoom and one in-person screening visit at Stanford Hospital. Participants will also complete daily assessments of sleep quality and dream experiences 2 weeks before and 2-4 weeks after the anesthesia session. In Phase I, participants will also wear the Muse headband to measure sleep quantity and quality daily for 2 weeks before and 2 weeks after the intervention session. In Phase II, participants will wear a GGX EEG Patch to measure sleep quantity and quality for 2 weeks before and 4 weeks after the intervention session. Participants will fill in pre-anesthesia and post-anesthesia questionnaires measuring mental health and well-being and, complete follow-up measures 1 day, 1 week, 2 weeks, 1 month, and 3 months after the anesthesia session.

During the anesthesia session, participants will undergo EEG-guided infusion of propofol.

In Phase I, all participants will undergo at least two sessions: (1) a sedation protocol intended to elicit dream reports (Dream Condition); and (ii) a sedation protocol designed to elicit non-dream experiential reports (Non-Dream Condition).

In Phase II, participants will be randomized into either the Dream or Non-Dream Group, undergoing either the protocol designed to elicit dream experiences or non-dream experiences, respectively.

Immediately upon emerging from anesthesia, participants will be interviewed using the modified Brice questionnaire and their responses audio- and video-recorded.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Clinician-Administered PTSD Scale for DSM-5 (CAPS-5)
Prazo: 1 month post-intervention

The CAPS-5 is a structured interview that is considered the gold standard for assessing post-traumatic stress disorder (PTSD). The CAPS-5 is designed to assess the 20 symptoms of PTSD as defined by the DSM-5, as well as the impact of these symptoms on social and occupational functioning. The CAPS-5 includes 20 items corresponding to the DSM-5 criteria for PTSD. Each item is rated for both frequency and intensity, with a 5-point scale (0-4) for each dimension. The total score ranges from 0 to 80, with higher scores indicating more severe symptoms. A score of >20 points indicates clinically significant PTSD symptoms. Superiority of "Dream Experiences Group" over "Non-Dream Experiences Group" will be demonstrated by a statistically significant greater decrease in the CAPS-5 when comparing pre-anesthesia scores to post-anesthesia scores.

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Proportion of Participants With Clinical Response
Prazo: 1 month post-intervention

Clinical response is defined as a reduction of ≥15 points (or ≥30% - 50%) in the CAPS-5 total severity score from baseline (pre-anesthesia) to Day +30 post-anesthesia, comparing the Dream versus No-Dream groups.

1 month post-intervention
Proportion of Participants With Remission
Prazo: 1 month post-intervention

Remission is defined as obtaining a score of ≤20 points on the CAPS-5, comparing the Dream versus No-Dream groups.

1 month post-intervention
Change in the PTSD Checklist for DSM-5 (PCL-5)
Prazo: 1 month post-intervention

The PCL-5 is a self-report measure designed to assess the 20 symptoms of post-traumatic stress disorder (PTSD) as defined by the DSM-5. Includes 20 items that correspond directly to the DSM-5 criteria for PTSD. Each item is rated on a 5-point Likert scale from 0 (Not at all) to 4 (Extremely), indicating how much the symptom has bothered the individual in the past week/month. The total score can range from 0 to 80, with higher scores indicating more severe PTSD symptoms. A score of 31-33 or higher is considered indicative of symptomatic PTSD. A reduction in PTSD symptoms will be indicated by a change in the PCL-5 total score from baseline (pre-anesthesia) to post-anesthesia, comparing the Dream versus No-Dream groups.

1 month post-intervention
Treatment Response Assessed Using the PTSD Checklist for DSM-5 (PCL-5)
Prazo: 1 month post-intervention

Proportion of participants achieving a reduction of ≥30% in the PCL-5 total score from baseline to Day +30, comparing the Dream versus No-Dream groups.
