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 55 to 75 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: 112 subjects with normal sleep breathing (non-OSA) or mild to moderate OSA (AHI4%<30).

Who may be able to join

  • To be eligible to participate in this study, an individual must meet all of the following criteria:
  • Male and female subjects with normal cognition and 55-75 years.
  • Within normal limits on neurological and psychiatric examinations. All subjects enrolled will have a CDR=0.
  • All subjects will have had a minimum of 12 years of education. Among minority subjects >80% of the elderly individuals coming to the NYU-ADC meet this criterion. The education restriction reduces performance variance on cognitive test measures and improves the sensitivity for detecting pathology and disease progression using the robust norms available at NYU. Given most subjects will meet this criterion we do not consider this a major selection bias or generalization limitation for this study.
  • An informed family member or life-partner (preferably bed-partner) will be interviewed to confirm the reliability of the subject interview.

Who cannot join

  • An individual who meets any of the following criteria will be excluded from participation in this study:
  • History of brain tumor, MRI evidence of brain damage or brain disease including significant trauma, hydrocephalus, seizures, mental retardation or other serious neurological disorder (e.g. Parkinson's disease or other movement disorders).
  • Significant history of alcoholism or drug abuse.
  • History of psychiatric illness (e.g., schizophrenia, bipolar, PTSD, or life-long history of major depression).
  • Geriatric Depression Scale (short form)>6.
  • Insulin dependent diabetes.

  • Evidence of clinically relevant cardiac, pulmonary, endocrine or hematological conditions.
  • Physical impairment of such severity as to adversely affect the validity of psychological testing.
  • Any prosthetic devices (e.g., pacemaker or surgical clips) that constitutes a hazard for MRI imaging.
  • Medications affecting cognition: Narcotic analgesics, chronic use of medications with anticholinergic activity, anti-Parkinsonian medications (carbidopa/levodopa, amantadine, bromocriptine, selegiline). Others: amphetamines, amphetamine-like compounds, appetite suppressants, phenothiazines, reserpine, buspirone, clonidine, disulfiram, guanethidine, MAO inhibitors, theophylline, tricyclic antidepressants, salicylates, cholinesterase inhibitors and memantine.
  • History of a first-degree family member with early onset (age <60 years) dementia.
  • Irregular sleep-wake rhythms (based on the actigraphy recordings) or severe OSA (AHI4%≥30).
  • Chronic use of antidepressants and melatonin are allowed.
  • Excessive daytimes sleepiness (Epworth Sleepiness Scale >10) or history of CVE (arrhythmias, heart valve disease, cardiomyopathy, carotid or coronary artery disease and chest pain) will not be allowed in the OSA groups.

About this study

Official title: Sleep Aging and Risk for Alzheimer's Resubmission 2.0

Age-related sleep changes and common sleep disorders like obstructive sleep apnea (OSA) may increase amyloid burden and represent risk factors for cognitive decline in the elderly. We will directly interrogate the brain using a 2-night nocturnal polysomnography (NPSG) and amyloid deposition using C-PiB PET/MR both at baseline and at the 24-month follow-up. This study has the potential to identify the mechanisms by which age-related sleep changes contribute to AD neurodegeneration in cognitively normal elderly, the group that could profit the most from sleep preventive strategies.

Being tested
PET Scan and nocturnal polysomnography

What participants receive

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

  • PET Scan and nocturnal polysomnographyDiagnostic test

    Amyloid PET scans will be used to assess amyloid burden in the brain, and nocturnal polysomnography will be used to assess sleep and cardiopulmonary variables

Study groups in NCT03278119
Study groupRoleWhat they receive
Sleep ApneaOverall 56 * both male and female * age group 55 to 75 years, having mild to severe obstructive sleep apnea * in good general health with no significant comorbidities * Located for the most part in boroughs of New York City
Receives: Diagnostic Test: PET Scan and nocturnal polysomnography
No Sleep ApneaOverall 56 * both male and female * age group 55 to 75 years, without OSA * in good general health with no significant comorbidities * Located for the most part in boroughs of New York City
Receives: Diagnostic Test: PET Scan and nocturnal polysomnography

What is being measured

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

  1. Establishing how mild-to-moderate OSA increases AD risk will inform novel preventive therapies for AD.

    Measured: 2.5 years

Secondary outcomes (1)
  1. Establishing that SWS quality is associated with longitudinal amyloid deposition will identify a key mechanism by which age increases AD risk.

    Measured: 2.5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer Disease and Sleep Apnea, run by NYU Langone Health 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 5 inclusion and 14 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: under way, not looking for participants, as of the sponsor's last update on 30 Mar 2026. 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?

This study is still under way. Results are not available in the source record yet.

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?

Establishing how mild-to-moderate OSA increases AD risk will inform novel preventive therapies for AD. (time frame: 2.5 years). 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 30 Mar 2026.
