Summary
This study tests if 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 disease. The treatment, called photobiomodulation, is low-risk and aims to boost brain cell energy. 168 participants will receive either real or sham light therapy for 12 weeks, with follow-up to see if it helps thinking skills.
