Hypothesis
Older adults with mild cognitive impairment (MCI) are less accurate in self-reporting sleep than those without MCI.
Conclusion
Older adults with MCI may be less accurate at recalling sleep duration, but their ability to distinguish sleep duration from time spent in bed is similar to those without MCI.
Supporting Evidence
- Older adults with MCI had a mean absolute difference in sleep duration of 6.04 hours.
- Older adults without MCI had a mean absolute difference in sleep duration of 6.42 hours.
- The study used wrist-worn actigraphy to objectively assess sleep.
Takeaway
This study looked at how well older people with memory problems remember their sleep compared to those without. It found that while they might not remember sleep duration as well, they can still tell how long they actually slept.
Methodology
The study compared sleep assessments using the Pittsburgh Sleep Quality Index and wrist-worn actigraphy among older adults with and without MCI.
Limitations
The study's sample size was small, particularly for the group with MCI.
Participant Demographics
Community-dwelling low-income older adults, with 13 participants having MCI and 77 without MCI.
