UA researchers study effects of near-infrared light on aging brains

Researchers hope the treatment will boost energy metabolism in brain cells and tune up mitochondria.

Researchers at the University of Arizona have received $1.8 million from the National Institute on Aging to study whether near-infrared light can help revitalize aging brains.

They will partner with scientists at the University of Florida on the project, which received a total of $3.8 million in funding.

Scientists have previously studied the potential benefits of near-infrared light for treating wounds and reducing muscle injury and pain.

The new five-year study will use a skullcap and nasal device to expose 168 participants to the energy, which is invisible and cannot be felt. Researchers hope the treatment will boost energy metabolism in brain cells and tune up the cellular power plants known as mitochondria.

"So if we can enhance that function through this administration of this near-infrared light, we think we can improve cognitive function along the way," said co-principal investigator Gene Alexander of UA's Evelyn F. McKnight Brain Institute.

Researchers will begin to enroll participants in both Arizona and Florida over the next few months. They will look for 65- to 89-year-olds who are cognitively healthy but at risk for Alzheimer's disease.
