Summary

This study tests whether three months of flicker stimulation (using near-infrared light or visual occlusion glasses) can improve thinking, movement, and mood in healthy older adults and those with subjective cognitive decline. Sixty participants aged 65-89 will be assigned to different stimulation groups. Researchers will measure changes in cognition, grip strength, walking speed, balance, and brain structure using MRI and blood tests.

What this could mean

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

Active substance: Flicker stimulation (near-infrared light and visual occlusion glasses)
What this could lead to: If it works, this could point toward a non-invasive way to slow age-related brain changes and improve daily function in older adults.
What could go wrong: This is an early-stage study with only 60 participants, so results may not apply widely. The intervention is experimental and may not produce meaningful benefits.
