How couples' sleep and daily routines affect memory and Alzheimer's risk

Dyadic Sleep, Biobehavioral Rhythms and Cognitive Function in Older Adults: Implications for Alzheimer’s Disease

NIH-funded research Utah State Higher Education System--University of Utah · NIH-11311288

This project explores whether shared sleep patterns and daily routines between older adults with mild cognitive problems and their partners influence memory and future Alzheimer's risk.

What this research studies

Researchers will follow couples where one partner has mild cognitive impairment or mild Alzheimer's and collect daily sleep and activity data using wearable monitors, sleep diaries, and questionnaires. They will measure how partners' sleep affects each other (interdependence) and how closely their routines match (concordance), then link those patterns to cognitive tests and health measures. The study combines day-to-day tracking with longer-term follow-up to see which shared sleep and rhythm patterns predict changes in memory and wellbeing. Results will consider effects on both the person with cognitive impairment and their partner.

Who could benefit from this research

Good fit: Ideal participants are older adults with mild cognitive impairment or mild Alzheimer's who live with and can enroll together with a spouse or partner and complete sleep monitoring and brief cognitive testing.

Not a fit: People who live alone, have moderate-to-severe dementia, cannot consent, or cannot participate in sleep monitoring are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, the work could identify sleep- and routine-based changes couples can adopt to help protect memory and improve daily functioning.

How similar studies have performed: Previous research links sleep disruption to cognitive decline, but studying shared sleep patterns within couples is a newer approach with limited prior trials.
