After seeing the beneficial results of 40Hz lights reducing amyloid plaques in mice, researchers began a human study on the safety, tolerability, and feasibility of 40Hz lights. Participants were enrolled in a trial at Emory University where they were shown flickering lights to determine whether there were adverse effects to the lights, that it was practical for the patients to use the lights for one hour each day, and how acceptable the different levels of light and sound intensity could be. Throughout the study, no severe side effects were found related to the lights. 95.5% participants adhered to keeping the lights on for one hour each day and agreed to continue to do so for another year. The study summarizes its findings by stating that the use of flickering lighters with patients with mild symptoms of Alzheimer’s is safe and feasible.
