The technique has yet to be tested on humans -- and probably won't be for some time -- but in a series of experiments on mice bred to develop Alzheimer's, regular ultrasound scans triggered the brain to clean up neurotoxic amyloids using immune cells called microglia.

"The ultrasound waves oscillate tremendously quickly, activating microglial cells that digest and remove the amyloid plaques that destroy brain synapses," explained Jurgen Gotz, director of the Clem Jones Center for Ageing Dementia Research, part of the Queensland Brain Institute.
