Daily Experiences Among Couples Living With Early-Stage Dementia: Implications for Daily Sleep and Long-Term Well-Being and Cognitive Function

NIH-funded research University of Michigan at Ann Arbor · NIH-11017074

This project looks at how daily stress and good moments affect sleep, mood, and memory in couples where one partner has early-stage dementia.

What this research studies

If you join, both you and your partner will take part in an hour-long phone interview and in-person memory testing at the start. Then for seven days you will each answer brief smartphone surveys five times a day about stress and positive experiences while wearing a sleep tracker overnight. The study will enroll 150 married or cohabiting couples aged 60 and older where one partner has early-stage Alzheimer's disease or a related dementia. Researchers will use the daily reports and sleep data to see how each partner’s day-to-day experiences relate to sleep and longer-term well-being and cognitive changes.

Who could benefit from this research

Good fit: Ideal participants are married or cohabiting couples aged 60 or older in which one partner has early-stage Alzheimer's disease or a related dementia and both can complete brief interviews, wear a sleep tracker, and use a smartphone for daily surveys.

Not a fit: People with advanced dementia, those not living with a partner, or couples unable or unwilling to travel for in-person testing, use a smartphone, or wear a sleep device are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, this work could lead to better sleep and emotional-support strategies for couples living with early-stage dementia to help preserve well-being and thinking skills.

How similar studies have performed: Prior studies have linked sleep problems to worse mood and cognitive decline in dementia, but combining daily smartphone surveys with wearable sleep tracking in both partners is a newer approach.
