Using Sound Waves to Treat Alzheimer's

An excerpt from the book, Your Brain on Art discusses how researchers are using sound (and light waves) to treat Alzheimer's disease. It turns out that being exposed to 40 Hz tones, in the gamma range of brain waves appears to reduce amyloid peptides, considered to be symptoms of Alzheimer's disease. Gamma waves are above the theta (4-8 Hz) and alpha (8-13 Hz) we discussed in chapter 8, and are associated with conscious cognition and memory formation. Here's an article that excerpts the research: https://www.fastcompany.com/90867531/how-simple-sound-and-light-are-treating-alzheimers-disease.
