This study reviews the effects of photobiomodulation (PBM) on the aging brain, including both animal and human studies.
PBM uses light (620–1100 nm) to activate mitochondrial cytochrome c oxidase, producing improvements in brain metabolism and blood flow.
In human studies, PBM has been shown to improve cognitive function, attention, learning, memory, and mood (p-values not provided), suggesting therapeutic potential for age-related declines in brain function.
