The U.S. Food and Drug Administration has approved a treatment that uses focused ultrasound on both sides of the brain (in two procedures, months apart) for the management of Parkinson’s-related motor symptoms.
This is an advance in focused ultrasound (FUS), a noninvasive surgical approach that uses sound waves to create heat and destroy a small area of brain tissue involved in Parkinson’s. But until this latest advance, FUS could only be performed on one side of the brain. The new approach targets a different area of the brain, making it able to treat tremor, slowness, stiffness and involuntary movement (dyskinesia) on both sides of the body.
