Study summary

The Combating Alzheimer's through Sleep and Exercise (CASE) study is an exploratory, hypothesis-generating trial designed to: (1) assess whether improvements in sleep are associated with improvements in cognitive performance and cardiovascular and metabolic health; (2) evaluate the effects of structured, moderate-level aerobic and anaerobic exercise on cognitive performance and cardiovascular and metabolic health; (3) examine the combined, potentially synergistic effects of both interventions on cognitive performance and cardiovascular and metabolic health; and (4) investigate the role of light exposure as a potential modulator of sleep parameters.

Inclusion criteria

  1. Aged 55-80 years at the time of the screening visit
  2. Able to ambulate safely and independently
  3. Able to safely perform moderate-intensity exercise as per the Physical Activity Readiness Questionnaire (PAR-Q, a validated exercise readiness questionnaire)
  4. Able to wear and use Fitbit wristwatch and/or the Elemind Neuromodulation headband and Lys devices
  5. Able to operate a digital device like mobile phone or computer
  6. Able and willing to provide venous blood samples
  7. Able to understand and speak English (our AR-based MCI diagnosis tool does not yet have capacity for other languages)
  8. Able to self-report a history of cognitive changes or impairment
  9. Be cognitively able (including those with and without MCI) and willing to provide
  10. Body weight \<400 pounds (\<181.4kg) in order to safely operate the NuStep T4r Recumbent Stepper stationary bicycle

Exclusion criteria

Exclusion Criteria:

  1. Severe mobility limitations that prevent safe participation in moderate exercise protocols
  2. Unstable or uncontrolled medical conditions (e.g., recent cardiovascular event (\<6 months), cerebrovascular accident or (\<6 months), active cancer, or uncontrolled diabetes) that pose safety concerns
  3. Inability to complete intake screening procedures
  4. Severe uncorrected hearing impairment-particularly if it precludes effective utilization of the Elemind Neuromodulation headband-and/or vision impairment that interferes with digital device usage or in-person exercise guidance
  5. Determined to have Alzheimer's/dementia based on performance on the Quick Mild Cognitive Impairment (QMCI).
  6. Inability or unwillingness to learn or engage with digital devices (e.g., smartphone, Fitbit, Elemind, or Lys), even with staff support
  7. Regular pre-study engagement in ≥150 minutes of moderate-level and/or ≥75 minutes of vigorous-level exercise per week based on Fitbit data obtained during the initial seven-day onboarding screening period
  8. Determined to have sufficient sleep, as defined by a sleep efficiency mean of ≥80%) based on Elemind Neuromodulation headband data obtained during the initial seven-day onboarding screening period
  9. Current usage of disease-modifying therapy targeting amyloid (e.g., anti-amyloid monoclonal antibodies) or tau
  10. Body weight ≥400 pounds (≥181.4kg), which would pose a safety risk during the operation of the NuStep recumbent stationary bicycle
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Study arms

  • Experimental
    Sleep Only Group

    Participants in this group will wear the Elemind headband 3-4 times weekly for 8 weeks.

    Device: Elemind Neuromodulation Headband

  • Active comparator
    Exercise Only Group

    Participants in this group will participate in a structured, on-site, twice a week exercise program for 60 minutes/session for 8 weeks (16 total sessions). Each exercise session is comprised of 60 minutes, including 10 minutes of warm-up, 20 minutes of cardiovascular exercise on a stationary bike, 20 minutes of resistance training (1 day of upper body focus, 1 day of lower body focus each week), and 10 minutes of cooling off).

    Other: Exercise Routine

  • Active comparator
    Exercise and Sleep Group

    Participants in this group will take part in the on-site, structured exercise program twice per week for 8 weeks in additional to wearing the Elemind headband 3-4 times per week for 8 weeks.

    Device: Elemind Neuromodulation Headband · Other: Exercise Routine

Interventions

  • DeviceElemind Neuromodulation Headband

    The Elemind Neuromodulation headband is a wearable device that utilizes noninvasive, electroencephalography-based (EEG-based) technology to induce a sleep state more rapidly via personalized acoustic stimulation. Specifically, the headband uses a closed-loop system, meaning that the headband conveys stimulation based upon recorded neural activity in order to modulate real-time oscillating circuits at the macroscopic level. This device uses five dry, flexible EEG electrodes-including three recording electrodes that are positioned at the Fpz and Fp1/2 electrode sites in accordance with the 10-20 International System of electrode placement and two silicone rubber-based, linked reference electrodes located at the mastoids-to measure neural activity during sleep and provide an estimation of the phases of real-time neural oscillations. The headband generates a sound pulse by identifying alpha neural oscillations in real-time through endpoint-corrected Hilbert Transform algorithm.

  • OtherExercise Routine

    Participants randomized to the exercise-only group will engage in an 8-week, home- and site-based exercise intervention designed for older adults across a range of cognitive and physical function levels. All site-based sessions will occur in-person at the study facility under supervision of trained staff. Each week, participants will attend two 60-minute structured exercise sessions, consisting of aerobic training and resistance training. On the remaining five days when subjects will not engage in structured exercise, subjects will be asked to engage in 30 minutes of moderate-intensity walking activities. In-lab exercise protocols will be fully standardized to ensure consistency of exercise dosage and fidelity across participants. The target exercise load will be 270 minutes of moderate-intensity exercise weekly for 8 weeks.
