As a minimally invasive approach, focused ultrasound has advantages over deep brain stimulation, including a reduced risk of complications from bleeding and infections, according to study lead author Federico Bruno, a radiologist at the University of L'Aquila in Italy. "Another advantage is the immediate effect this treatment provides, unlike deep brain stimulation which requires a break-in period for the electrostimulation," he said. "Additionally, treatment with MRgFUS requires shorter hospitalization and is a fairly well-tolerated procedure even by more fragile patients."
