NCT ID NCT02817061
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether shining near-infrared light on the head (called transcranial photobiomodulation) can improve thinking, memory, and mood in healthy adults. Eighty volunteers aged 18-25 or 65-85 received the light treatment or a placebo. The goal was to see if this safe, non-invasive approach could enhance cognitive function, measured by computer-based tests.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
near-infrared light (transcranial photobiomodulation via Omnilux device)
What this could lead to
If it works, this could point toward a non-drug way to boost memory and focus in healthy people.
What could go wrong
This is a very early, small study in healthy volunteers, not patients. The effects may be small or not real, and results may not apply to people with cognitive problems.
