Brain Sleep Deprivation MRI Effects (BEDTIME) (BEDTIME)

July 9, 2020 updated by: NYU Langone Health

Open Masking, Micro Motionlogger Actigraph, 3T Siemens MRI, Sleep Deprivation, Nocturnal PSG

The primary purpose of this study is to explore the underlying mechanisms that link sleep to Alzheimer's disease (AD), with special focus on the clearance of metabolites in the extracellular space of the brain during sleep. Subjects will wear an actigraph for 1 week to determine regular daytime activity and sleep patterns. Subjects will then undergo partial sleep deprivation followed by 4 hours of in-lab nocturnal polysomnography (NPSG). Participants will be be asked to stay awake and active all day after the partial sleep deprivation with a new actigraphy secured by a hospital band to assure participants remain awake. They will seep inside an MRI machine for 90 minutes on the following night during their usual bedtime (established by 1 week actigraphy study.) Morphologic imaging, flow imaging and diffusion kurtosis imaging (DKI) will be performed on a 3T Siemens scanner.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 30 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age range 21-30
  • Capable of giving informed consent

Exclusion Criteria:

  • Diagnosis of any brain disease or brain damage including significant trauma, hydrocephalus, seizures, mental retardation or other serious neurological disorders (e.g. Parkinson's disease or other movement disorders). Persons with silent cortical infarcts will be excluded. White matter lesions will not be exclusions.
  • History of major psychiatric illness (e.g., schizophrenia, bipolar or life long history of major depression)
  • Conditions that alter normal sleep patterns: irregular sleep-wake rhythms (based on one week at home monitoring with actigraphy), moderate to severe periodic limb movement while you sleep (PLMS) or Obstructive Sleep Apnea (OSA).
  • History of claustrophobia.
  • BMI≥30
  • Significant history of alcoholism or drug abuse.
  • Inability to avoid the use of alcohol or caffeine during the 48h before the MRI.
  • Current pregnancy or intent to become pregnant during the period of study.
  • Any electronic or ferromagnetic devices (e.g., pacemaker or surgical clips) that constitutes a hazard for MRI imaging.
  • Any medications adversely affecting cognition, blood pressure, glucose metabolism, or sleep will result in exclusion.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Measure of Interstitial Space Volume during sleep using MRI imaging
Time Frame: 6 Months
Data will be acquired using imaging sequences that comply with federal limits regarding radiofrequency energy deposition and gradient slew rates.
6 Months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Changes in Cerebral Spinal Fluid volume measured by increases in the power of slow wave activity (SWA)
Time Frame: 6 Months
Data will be acquired using imaging sequences that comply with federal limits regarding radiofrequency energy deposition and gradient slew rates.
6 Months

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
