Summary

This study tests whether using a device that delivers light and sound stimulation for 60 minutes each day is safe and practical for people with mild Alzheimer's. Fifteen participants will use the device at home for 6 to 9 months. The main goals are to see if people can stick with the daily routine and if any side effects occur.

What this could mean

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

Active substance: GENUS device (light and sound stimulation)
What this could lead to: If it works, this could point toward a non-drug way to ease Alzheimer's symptoms at home.
What could go wrong: This is a very small, early feasibility trial with only 15 people. It focuses on safety and device use, not yet on whether it truly helps memory or thinking.
