40 Hz Sound May Help the Brain Clear Alzheimer's Toxins in Primates
TL;DR Summary
In nine elderly monkeys, daily 40 Hz sound for one week increased cerebrospinal fluid levels of β-amyloid by about 200%, suggesting the brain’s waste-clearance system was more active and the effect lasted five weeks. The results are preliminary, focusing on biomarkers rather than memory outcomes, and human trials are needed to determine real-world therapeutic potential.
