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.

Li-Huei Tsai: Could we treat Alzheimer's with light and sound?

Could we treat Alzheimer's with light and sound?

Artificially boosting gamma brainwaves might counteract Alzheimer's by enhancing brain synchrony and information processing.

Gamma wave stimulation in mice shows reduced Alzheimer's markers, offering hope for a non-invasive treatment for humans.

Light and sound therapy shows promise in early human trials, potentially paving the way to a future free from Alzheimer's.
