Scientists found that using a special sound wave treatment on mice with Alzheimer’s-like brain changes reduced two key signs of the disease—tau protein buildup and tangled nerve cell branches—by nearly a third and half, respectively, after four treatments.

Scientists found that when they used sound waves and tiny bubbles on mice with a brain disease similar to Alzheimer’s, a specific gene in their memory center became more active—and this might help clear out the sticky proteins that cause brain problems.

Scientists used a special sound wave treatment on mice with Alzheimer’s-like brain changes, and after four weekly sessions, they saw fewer and smaller clumps of harmful protein in the memory area of the brain—but the loose, floating version of that protein didn’t change much.
