Ultrasound used as therapy for Alzheimer’s

Researchers at the University of Queensland in Australia have found that non-invasive ultrasound can break down the neurotoxic amyloid plaques associated with Alzheimer’s. Their research was published in the journal Science Translational Medicine.

Researchers used repeated scanning ultrasound treatments of the mouse brain to remove the amyloid plaques, without the need for any additional therapeutic agent. The scientists discovered that the ultrasound waves activate microglial cells, which digest and remove the amyloid plaques associated with Alzheimer’s. In their studies, memory function was restored to a normal healthy level in 75% of their subjects.
