Longitudinal Remote Sleep and Cognitive Research in Older Adults With Mild Cognitive Impairment and Dementia: Prospective Feasibility Cohort Study
Victoria Grace Gabb, Jonathan Blackman, Hamish Duncan Morrison, Haoxuan Li, Adrian Hugh Kendrick, Nicholas L Turner, Rosemary Greenwood, Bijetri Biswas et al.. JMIR Aging, 2025-04-28
Topic: Risk, prevention and care in population studies
In total, 41 participants consented (n=10, 24% participants with Alzheimer disease; n=11, 27% participants with Lewy body disease; and n=20, 49% controls). There were predominantly male and White British participants, with a mean age of 70.9 (SD 5.9) years. Retention was very high, with 40 (98%) participants completing 8 weeks of remote monitoring. Data completeness for sleep electroencephalography was 91% and ranged from 79% to 97% for all remote tasks and was overall high across all participant subgroups. In total, 30% (12/40) of participants reported receiving external support with completing study tasks. High rates of retention, data completeness, and data quality suggested that longitudinal multimodal sleep and cognitive profiling using novel and remote monitoring technology is feasible in older adults with MCI and dementia and healthy older adults, even without study partner support. Remote monitoring should be considered for mechanistic and interventional trials. Careful consideration should be given to how to ensure remote monitoring technologies reduce burden and enhance inclusivity, particularly in communities traditionally underserved by research and those with lower digital literacy.

Key findings
- In total, 41 participants consented (n=10, 24% participants with Alzheimer disease; n=11, 27% participants with Lewy body disease; and n=20, 49% controls).
- There were predominantly male and White British participants, with a mean age of 70.9 (SD 5.9) years.
- Retention was very high, with 40 (98%) participants completing 8 weeks of remote monitoring.
- Data completeness for sleep electroencephalography was 91% and ranged from 79% to 97% for all remote tasks and was overall high across all participant subgroups.
- In total, 30% (12/40) of participants reported receiving external support with completing study tasks.
Why it matters
This feasibility study found that remote sleep and cognitive monitoring was feasible in older adults with mild cognitive impairment and dementia, with high retention and data completeness. It supports the use of remote monitoring in future trials but does not test any treatment, cure, or prevention.
