Read our Alzheimer's Disease research guide →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 a 40 Hz light therapy system — a device that uses invisible flickering light designed to stimulate specific brain patterns — as a potential treatment for Alzheimer's disease. Researchers hope this approach may help slow disease progression and improve memory and thinking skills. You would use the device for one hour each day and be monitored with memory tests and brain imaging over 12 months.
Recent animal studies have shown that this invisible light therapy may slow Alzheimer's progression and help protect brain cells, but it has never been properly tested in people with Alzheimer's. This trial aims to see whether the treatment works in humans and could become an important new therapy option.

You would use the light therapy device at home for one hour every day for 12 months total. The study has three parts: an enrollment period, then 6 months where you randomly receive either the active invisible-flicker light or regular white light (you won't know which), followed by 6 months of active treatment. Throughout the year, you'll have memory and thinking tests, brain scans, and blood work to measure how the treatment affects your brain. Your caregiver will help you use the device and attend clinic visits with you.
