Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 60 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Study population: Subjects will be recruited from the greater Madison, WI area. Hypersomnolent subject groups (n=30 in each group) may include unipolar MDD with hypersomnolence, primary hypersomnia (idiopathic hypersomnia), bipolar disorder with hypersomnolence, and narcolepsy. Non-hypersomnolent comparison groups (n=30 in each group) will include: MDD without hypersomnolence, bipolar disorder without hypersomnolence, primary insomnia, and healthy controls.

Who may be able to join

  • Meet Diagnostic and Statistical Manual edition IV criteria for neuropsychiatric disorders enumerated in study population description

Who cannot join

  • Exclusionary criteria for all subjects will include: evidence of a clinically significant sleep disorder that would cause hypersomnolence (e.g. moderate to severe obstructive sleep apnea, restless legs syndrome, shift-work sleep disorder), history of significant head trauma or loss of consciousness > 30 minutes; current smoking of more than 15 cigarettes per day; >3 caffeinated beverages per day; significant neurologic or medical illness; active drug/alcohol abuse/dependence (within 6 months of enrollment), women who are pregnant, <6 months post-partum, nursing or planning to become pregnant during the study; left-handedness (due to effects on sleep topography); and imminent risk for self-harm or suicide.

About this study

Official title: Neurophysiologic Correlates of Hypersomnia: a High Density EEG Investigation

The goal of this project is to examine the neurophysiology of hypersomnia during sleep and wakefulness, to identify biomarkers for excessive sleepiness in neuropsychiatric disorders, and pilot acoustical slow wave induction during sleep in patients with hypersomnolence, to determine if this decreases daytime sleepiness in these patients. The primary study hypotheses are that individuals with hypersomnolence will have reduced slow wave activity (SWA) during sleep and increased waking theta/alpha activity during wake in specific brain regions. A secondary hypothesis is that acoustical slow wave induction in hypersomnolent patients will increase SWA during sleep, reduce theta/alpha activity during wake, and improve subjective sleepiness.

Acoustical slow wave induction

Depressive Disorder, Major, Idiopathic Hypersomnia, Bipolar Disorder, Narcolepsy, Sleep Initiation and Maintenance Disorders

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Acoustical slow wave inductionOther

    Brief tones (50 millisecond duration) at a frequency of 0.8 and 2 Hz, a rate that approximates the natural cellular oscillations of cortical neurons during sleep, will be played in blocks of 15-20 during non-rapid eye movement (NREM) sleep. Blocks of active acoustic slow wave induction will be followed by blocks of equal duration without induction, in order to make comparisons between stimulation periods (ON) and no stimulation periods (OFF). Tone intensity will be manually adjusted so as to be above an individual participant's auditory threshold during waking, but still quiet enough as not to awaken the subject from sleep. Sham slow wave induction will consist of auditory tones played prior to sleep, and during sleep of insufficient timing and intensity to alter slow wave activity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nocturnal Slow Wave Activity

    EEG recordings during sleep will be analyzed to assess slow wave activity in the 1-4.5Hz range.

    Measured: Individual nights of sleep recorded within an average of 4 weeks of enrollment

Secondary outcomes (1)
  1. Waking theta/alpha activity

    Waking EEG activity across the 1-12Hz range will be analyzed.

    Measured: Individual days of waking EEG will be recorded within an average of 4 weeks of enrollment

Questions about this trial

What is this clinical trial studying?

An observational study of Major Depressive Disorder and Primary Hypersomnia, run by University of Wisconsin, Madison at 1 site in United States.

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 1 inclusion and 1 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 24 Dec 2018. 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 United States. 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?

Nocturnal Slow Wave Activity (time frame: Individual nights of sleep recorded within an average of 4 weeks of enrollment). 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 24 Dec 2018.
