Flickering light may boost brain function in Alzheimer's

NCT ID NCT05015478

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a special flickering light (40 Hz) can improve sleep and thinking in people with mild cognitive impairment or early Alzheimer's disease. Participants will sit under the light for one hour while researchers measure brain activity and memory. The goal is to see if this simple, non-drug approach can help calm brain rhythms and support better sleep.
