MCI & Sleep
Research Study
As we age, changes in sleep patterns can affect how well we think and remember information. Some older adults may notice mild memory challenges that go beyond normal aging. Researchers at Western University are interested in finding safe and simple ways to support brain health during this stage of life.

Additional Information
Sleep plays an important role in how the brain stores and processes memories, so sleep changes that come with aging can affect on thinking and memory. This study is exploring whether gentle sound cues played during sleep may help support memory and overall cognitive function. By learning more about how the brain responds during sleep, researchers hope to better understand ways to maintain brain health in older adults.
MCI is a condition in which a person experiences noticeable changes in memory or other thinking abilities that are greater than expected with normal aging, but are not severe enough to significantly interfere with everyday activities. These changes are not primarily caused by another medical or neurological condition, such as a stroke or traumatic brain injury.
You may be eligible for this study if you meet the following criteria.
Inclusion Criteria:
- Adults ages 60+
- Diagnosed with mild cognitive impairment (MCI), or suspect you may have MCI
- Experience memory problems (e.g., forgetting recent things, losing items)
- Live in London, Ontario or within about 50 km
Exclusion Criteria:
- History of sleep disorders
- Known stroke or transient ischemic attack (also known as a “mini stroke”)
- History of seizures
- Untreated moderate or severe sleep apnea
- Participants with well-controlled sleep apnea will be eligible to participate provided they are able to use their treatment device
If you are eligible and choose to participate, you may:
- Complete an online screening and a short phone interview
- Take part in simple hearing and memory tests
- Possibly complete an at home sleep screening
- Thirteen overnight sessions in the comfort of your home over three weeks
- Sleep while wearing a comfortable cap that records brain activity
- Complete memory and thinking tasks before and after sleep
Yes, you will be compensated for your time. There will be a small monetary compensation for completing the full screening protocol of the study, including the online questionnaires, phone interview and, if needed, the at-home sleep apnea test. If you meet eligibility criteria, you will be compensated for completing each overnight visit.
There is no cost for you to participate in our research study.
