Sound waves aim to replace brain surgery for Parkinson's

This study is exploring whether a new, non-invasive technique using focused ultrasound can safely stimulate deep brain areas in people with Parkinson's disease and dystonia. Researchers are testing this on a small group of patients who already have surgically implanted brain stimulators, allowing them to directly compare the effects of ultrasound to the existing treatment. The main goal is to understand how the ultrasound works and if it could one day offer a treatment option without the need for brain surgery.
