What if we could use brain waves to treat Alzheimer's? Professor and neuroscientist Li-Huei Tsai details a promising new approach to artificially stimulate gamma brain waves using light and sound therapy, to increase connectivity and synchrony and delay the onset of this deadly disease. This non-invasive therapy has already been shown to work in mice -- now it's on to human clinical trials, with the potential to usher in a brighter future for everyone. (Followed by a Q&A with head of TED Chris Anderson)

Artificially stimulating gamma brain waves with synchronized light and sound could help slow or prevent Alzheimer's disease. In studies, mice exposed to 40-hertz flickering lights and buzzing sounds showed reduced buildup of harmful brain proteins and preserved memory function. Early human trials using a non-invasive device reveal promising signs of improved brain synchrony and cognitive benefits. As Alzheimer's deaths have soared 145 percent over two decades, this accessible therapy could reshape treatment for millions.
