“Clumps of harmful proteins that interfere with brain functions have been partially cleared in mice using nothing but light and sound.

Research led by MIT has found strobe lights and a low pitched buzz can be used to recreate brain waves lost in the disease, which in turn remove plaque and improve cognitive function in mice engineered to display Alzheimer’s-like behaviour.

It’s a little like using light and sound to trigger their own brain waves to help fight the disease.
