TED Talks Daily Could we treat Alzheimer's with light and sound? | Li-Huei Tsai
May 29, 2023
Li-Huei Tsai, a pioneering neuroscientist focused on Alzheimer's disease, shares groundbreaking insights into using light and sound therapy as a potential treatment. She discusses how artificially stimulating gamma brain waves can enhance brain connectivity and may delay Alzheimer’s onset. This non-invasive therapy has shown promising results in mice, leading to upcoming clinical trials for humans. Tsai emphasizes the importance of early intervention and the hopeful future this research could bring for those at risk.

Episode notes
Gamma Brainwaves and Alzheimer's
- Gamma brainwaves synchronize brain activity to process information and form memories.
- Weakened gamma waves may contribute to Alzheimer's disease.
Personal Inspiration
- Li-Huei Tsai's grandmother suffered from Alzheimer's.
- This personal experience inspired Tsai's research career.
Light and Sound Stimulation
- Light and sound stimulation at 40 hertz can increase gamma wave power and synchrony in mice.
- This stimulation led to reduced protein buildups and improved memory performance in Alzheimer's mice models.
