NCT ID NCT07445945
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether shining red and near-infrared light on the forehead, inside the nose, and on the neck can improve memory and mood in older adults who feel their thinking is slipping. Eighty participants will use a light device at home twice daily for five weeks. Researchers will measure changes in mood, thinking, brain activity, and gut bacteria before and after the treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
photobiomodulation (red and near-infrared light)
What this could lead to
If it works, this could point toward a safe, non-invasive way to ease memory concerns and low mood in older adults without using drugs.
What could go wrong
This is a small, early-stage proof-of-concept study with no blinding or placebo control for all groups. The effects may be small or not last, and the device requires daily use at home.
