I understand Focused Ultrasound is being offered at the University of Pennsylvania in Philadelphia. One consideration is that the treatment is permanent and cannot be reversed or "shutoff". On the positive side it is a less invasive procedure with external ultrasound neutralizing a pinpoint location in the brain.
My wife had a very successful deep brain stimulation (DBS) procedure at UPENN. Many of her symptoms such as freezing improved and remain resolved five years later. Best wishes, Joe
