Beneficial neurocognitive effects of transcranial laser in older adults.

Transcranial infrared laser stimulation (TILS) at 1064 nm, 250 mW/cm has been proven safe and effective for increasing neurocognitive functions in young adults in controlled studies using photobiomodulation of the right prefrontal cortex. The objective of this pilot study was to determine whether there is any effect from TILS on neurocognitive function in older adults with subjective memory complaint at risk for cognitive decline (e.g.
