Using Near-Infrared Light to Improve Brain Function of Older Adults

UF’s Adam Woods, Dawn Bowers, and other researchers are examining the effects of applying near-infrared light to the scalps of older adults at risk of developing Alzheimer’s disease. If effective, it could offer a safe, accessible intervention for the disease, which currently has few effective therapies.

“Research [has demonstrated] that near-infrared light applied to neurons and other cells can increase…the energy metabolism of the cells,” Woods said. “Many different brain-based disorders have a major component of brain metabolism or brain energy being altered. Being able to improve brain energy could have [a] wide-spanning impact on [several] behavioral and brain functions.”
