UHS Wilson Medical Center Reaches Milestone with 100th Focused Ultrasound Procedure for Tremor

For decades, the primary surgical option for severe tremor was Deep Brain Stimulation, a procedure that, while effective, requires drilling into the skull and implanting electrodes. In recent years, however, a non-invasive alternative has moved from the fringes of science fiction to the forefront of standard care. Magnetic Resonance-guided Focused Ultrasound, often simply called focused ultrasound, uses high-intensity sound waves to target the exact spot in the brain responsible for the tremor. By concentrating these waves like a magnifying glass focuses sunlight, surgeons can create a tiny, therapeutic lesion that disrupts the abnormal circuit, often stopping the shaking instantly—all without a single incision. This technology has rapidly become a beacon of hope for people living with essential tremor and tremor-dominant Parkinson’s. It allows individuals to walk in for a procedure in the morning and return home the same day, often with the immediate ability to hold a cup of tea or sign their name for the first time in years. This shift towards non-invasive care was highlighted recently at UHS Wilson Medical Center in New York, where the neurosciences team celebrated a significant milestone: treating their 100th person using this state-of-the-art technology. The procedure has become an increasingly accessible option at the facility, offering a life-changing solution for those who have not found relief through medication alone. The 100th individual to undergo the treatment was 80-year-old John Paulsen. He had lived with essential tremor since he was 15, watching the condition slowly steal his independence over more than six decades. The simple pleasures of daily life had become impossible tasks; he could no longer write a legible letter, drink a cup of coffee without spilling it, or eat soup. Under the care of Dr Khalid Sethi, the Director of the UHS Neuroscience Institute, John underwent the incision-free procedure. Guided by real-time MRI imaging, the team targeted the specific area of his thalamus causing the disruption. The results were immediate and profound. Right on the treatment table, the tremor that had plagued him for sixty-five years vanished. For John, the impact was nothing short of miraculous. He described the ability to hold a cup steady and write his name again as a restoration of his freedom. His case serves as a powerful testament to how far this technology has come. Reaching the 100th procedure marks a transition for focused ultrasound; it is no longer just a novel experiment, but a robust, proven clinical option that is actively restoring quality of life to people with movement disorders.
