Combating Alzheimer's Through Sleep and Exercise
Combating Alzheimer's Through Sleep and Exercise (CASE)
Source: ClinicalTrials.gov · Last updated 27 Oct 2026
Brief summary (registry, in English)
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.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other illness
- Unstable or uncontrolled medical conditions (e.g., recent cardiovascular event (\<6 months), cerebrovascular accident or transient ischemic attack (\<6 months), active cancer, or uncontrolled diabetes) that pose safety concerns
- 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
- Determined to have Alzheimer's/dementia based on performance on the Quick Mild Cognitive Impairment (QMCI).
- Current usage of disease-modifying therapy targeting amyloid (e.g., anti-amyloid monoclonal antibodies) or tau
Other
- Severe mobility limitations that prevent safe participation in moderate exercise protocols
- Inability to complete intake screening procedures
- Inability or unwillingness to learn or engage with digital devices (e.g., smartphone, Fitbit, Elemind, or Lys), even with staff support
- 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
- 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
- Body weight ≥400 pounds (≥181.4kg), which would pose a safety risk during the operation of the NuStep recumbent stationary bicycle
Who the study is looking for
- Aged 55-80 years at the time of the screening visit
- Able to ambulate safely and independently
- Able to safely perform moderate-intensity exercise as per the Physical Activity Readiness Questionnaire (PAR-Q, a validated exercise readiness questionnaire)
- Able to wear and use Fitbit wristwatch and/or the Elemind Neuromodulation headband and Lys devices
- Able to operate a digital device like mobile phone or computer
- Able and willing to provide venous blood samples
- Able to understand and speak English (our AR-based MCI diagnosis tool does not yet have capacity for other languages)
- Able to self-report a history of cognitive changes or impairment
- Be cognitively able (including those with and without MCI) and willing to provide informed consent
- Body weight \<400 pounds (\<181.4kg) in order to safely operate the NuStep T4r Recumbent Stepper stationary bicycle
Age in the registry: 55 years to 80 years · Sex: All · Accepts healthy volunteers
