Summary

This study tests whether spending less time in bed for four weeks can deepen sleep and boost memory in adults aged 65-85 who have poor sleep and are at risk for Alzheimer's. Researchers will measure brain activity, memory, and blood markers. The goal is to see if a simple behavioral change can reduce Alzheimer's-related brain changes.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Time in bed restriction (behavioral sleep intervention)
What this could lead to: If it works, this could point toward a simple, drug-free way to slow Alzheimer's-related memory decline by improving sleep quality.
What could go wrong: This is a very early, small study (116 people) testing a behavioral change, not a treatment. Results may not lead to a proven therapy, and sleep restriction can be uncomfortable.
