Light therapy shows promise for preventing Alzheimer's in seniors

This study tests whether shining a special near-infrared light on the head and through the nose can improve memory and brain function in older adults at risk for Alzheimer's. 168 volunteers aged 65-89 with memory concerns and a family history of Alzheimer's will receive either real or fake light treatments for 12 weeks. The goal is to see if this safe, low-cost approach can boost brain energy and connectivity, potentially delaying or preventing Alzheimer's.
