Stimulating a key brain rhythm with light and sound increases peptide release from interneurons, driving clearance of Alzheimer's protein via the brain's glymphatic system, new study suggests. https://www.sciencedaily.com/releases/2024/02/240228114328.htm Alzheimer's is a disease for which there aren't any good therapeutic approaches. Drugs to combat the accumulation of beta amyloid have not been very successful. Stimulating the brain with 40 Hz light and sound would appear to be easily implemented. Testing it may be a little problematic, since a "double-blind" experiment is not possible.
