Sleep health of assisted-living residents
Understanding the Association Between Sleep Quality, Physical Activity, and Memory in Assisted-Living Residents
This project tries to see if sleep quality is linked with physical activity, functional ability, and memory in older adults living in assisted-living facilities.

What this trial studies
This cross-sectional feasibility study recruits inactive assisted-living residents and uses overnight polysomnography, wrist actigraphy, and sleep questionnaires to objectively measure sleep quality. Participants complete functional and physical tests plus cognitive testing (including the MoCA and memory-focused assessments) to examine links between sleep, activity, and cognition. The protocol includes a comparison group of community-dwelling older adults of similar age and cognitive status to contextualize findings. The primary aim is to test whether polysomnography and actigraphy can be feasibly implemented in assisted-living settings and to explore associations among sleep, functional capacity, and memory performance.
Who should consider this trial
Good fit: Ideal participants are ambulatory assisted-living residents who are relatively cognitively intact (CPS 0–3), speak English, have life expectancy greater than one year, and are inactive (<3 sessions/week of vigorous exercise).
Not a fit: Patients with severe cognitive impairment (CPS >3), terminal illness, non‑English speakers, wheelchair-dependent residents, or those with medical/neurological conditions that would confound cognitive testing are unlikely to benefit or be eligible.
Why it matters
Potential benefit: If successful, this work could improve detection of sleep disorders in assisted-living residents and guide targeted activities or treatments that may slow or delay cognitive decline.
How similar studies have performed: Community-based studies have linked activity, sleep, and cognition, but applying overnight polysomnography and actigraphy specifically in assisted‑living residents is largely untested and represents a novel feasibility effort.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Be inactivity, which will be defined as an engagement in \< 3 sessions/week of 20 min or more of vigorous exercise; * Be able to move independently without the assistance of a wheelchair. Exclusion Criteria: * Diagnosis of a developmental handicap; * Residents who are not able to understand communication and be understood by others and do not have decision-making capacity according to the Cognitive Performance Scale (CPS) \> 3; The investigators will assess all the resident's capacity with the Brenda Strafford Foundation caregivers, even if their CPS is within the range included in the study (CPS 0-3); * Terminal illness (life expectancy \< 1 year); * Not fluent in English; * Currently participating in another trial; * Comorbid medical or neurological illnesses (e.g., multiple sclerosis) that would confound cognitive assessments or make trial completion unlikely (in the site investigator's opinion); * Contraindication for the tests.
