Abstract
Photobiomodulation (PBM) is a novel interventional therapy that stimulates brain tissue with light at infrared to near-infrared wavelengths, which is applied in the treatment of various neurological and psychological disorders including Alzheimer’s disease, Parkinson’s disease, depression, stroke, and traumatic brain injury. Studies also suggest that PBM is effective in enhancing cognitive functions such as sustained attention and short-term memory in normal individual. The widely recognized PBM mechanism is that the absorption of light by neurons leads to an increase in mitochondrial activity and also an increase in cerebral blood flow. Other studies suggest that the sustained effect of light can only be explained by activating signal pathways and transcription factors that cause changes.
