Trial summary

Sleepwalking (also called somnambulism) is a disorder in which only SWS is disrupted. This NREM parasomnia is characterized by inappropriate motor behaviors, usually initiated during arousal from SWS, that induce psychological distress and alter quality of life, leading to fatigue, excessive daytime sleepiness, and… Read more about this study

About this study

Sleepwalking (also called somnambulism) is a disorder in which only SWS is disrupted. This NREM parasomnia is characterized by inappropriate motor behaviors, usually initiated during arousal from SWS, that induce psychological distress and alter quality of life, leading to fatigue, excessive daytime sleepiness, and objectively impaired vigilance in the morning.

The pathophysiology of sleepwalking remains poorly understood. Sleepwalkers had difficulty maintaining stable, consolidated sleep and experienced more arousals and microarousals, specifically from SWS, leading to increased NREM instability, especially during the first sleep cycles. The brain is partially awake, resulting in behavioral manifestations, and partially in NREM sleep, resulting in no conscious awareness of actions.

A Single Photonic Emission Computed Tomography (SPECT) study of one sleepwalking episode found increased activation in the posterior cingulate cortex and cerebellum, with deactivation in the frontoparietal associative cortices. Data from intracerebral EEGs during confusional arousals confirmed both local arousal of the motor and cingulate cortices and increased delta activity in the frontoparietal associative cortices.

The investigators thus proposed a controlled study of SPECT imagery in 24 sleepwalkers (12 SPECT during a SW episode and 12 SPECT during slow wave sleep and 24 during wakefulness) and 12 controls (during slow wave sleep and wakefulness). SW episodes will be elicited by sleep deprivation condition associated with forced arousal (auditory stimulus).

The comparative analyses of SPECT acquisitions between different states (wakefulness, slow wave sleep and SW) and populations (sleepwalkers versus controls) will provide new insights about the complex pathophysiology of SW episodes.

Questions about this trial

What is this clinical trial studying?

A study testing Single-photon emission computed tomography in people with Sleepwalking, run by University Hospital, Montpellier at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Brain metabolism measurement with brain scintigraphy (time frame: Day 0). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2024.
