This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a simple home sleep test is better than an overnight lab test for detecting sleep apnea — a condition where breathing pauses during sleep — in people with memory loss or cognitive decline. Sleep apnea is common in these patients and can make thinking problems worse, but many people aren't tested because lab testing is inconvenient. The study will compare how many people actually complete each type of test and whether the home test leads to better outcomes.
Sleep apnea is very common in people with Alzheimer's disease and other types of dementia, and it makes cognitive problems worse. However, the current standard test — an overnight stay in a sleep lab — is difficult for people with cognitive impairment and their caregivers. This trial exists to see if a simpler home-based test could help more patients get diagnosed and treated.

You will be randomly assigned to either a home sleep test or an overnight lab test. If you're assigned to the home test, you'll wear a small device at home while you sleep — no overnight stay required. If assigned to the lab test, you'll spend one night in a sleep clinic being monitored. Either way, you'll return for follow-up visits at 6 months to complete thinking and mood assessments, discuss any treatment with a CPAP machine, and share your experience with the testing method.
