Photobiomodulation

The reviewed human outcome measures working-memory performance in a specific laser protocol. Durability and applicability require their own evidence.

A change in a laboratory marker, a test score and everyday function are different outcomes. A statistically detectable result does not by itself tell us whether someone would notice a worthwhile difference.

Check the measured endpoint, comparison and study population. The full profile preserves effect estimates and the source's clinical-significance assessment, including when that assessment is not supplied.

The claim to test: A short cognitive-task result establishes lasting cognitive improvement or slower aging.

What the reviewed records say:

The gap: Wavelength, delivery site and session design matter. A single-session result does not establish long-term benefit or safety.

Durability, effects in other populations and healthy-lifespan outcomes need their own evidence.

Independent replication, meaningful human outcomes, longer follow-up and better safety reporting would make these results easier to interpret.

Wavelength, delivery site and session design matter. A single-session result does not establish long-term benefit or safety.
