Brain Ultrasound Treats Parkinson's Symptoms Without Surgery

Stan Au's hands shook so badly he couldn't hold a fork or sign his name, but a three-hour ultrasound treatment changed everything without a single incision.

After living with Parkinson's disease for 12 years, the New Jersey resident had watched his symptoms worsen despite medication. Playing pickleball became impossible. Simple tasks turned into daily battles.

When his wife Pam learned about a clinical trial at Weill Cornell Medicine, Stan finally found an alternative to the brain surgery he'd been dreading. Dr. Harini Sarva recommended magnetic resonance-guided focused ultrasound, a procedure that uses sound waves to target abnormal movement signals deep in the brain.

The treatment works by creating a tiny, precise lesion in the brain's movement control pathway. Patients wear a helmet inside an MRI machine while ultrasound beams pass through the skull to the exact target. Real-time imaging guides doctors to interrupt the faulty signals causing tremors and stiffness.

Dr. Michael Kaplitt led the groundbreaking clinical trial that tested the procedure on both sides of the brain. Previous FDA approvals only allowed treatment on one side, limiting relief for patients whose symptoms affected their entire body.

The trial included 54 Parkinson's patients, with 40 choosing to have both sides treated. Results showed 86% of patients reported improvement three months after their second procedure. Stan experienced immediate benefits, including less stiffness and better coordination that allowed him to return to an active lifestyle.

The FDA approved bilateral treatment in July 2025 based on these results, and Medicare began covering it this March. The agency noted that while the second treatment carries higher risks for speech and balance issues, carefully selected patients can now address disabling symptoms on both sides of their body.

The Bright Side

About 1 million Americans live with Parkinson's disease, and while there's no cure yet, this advancement gives patients more control over managing their symptoms. The outpatient procedure takes just three to four hours and requires no implants or incisions.

The treatment represents a partnership between doctors and patients searching for solutions that fit individual needs and comfort levels. For people like Stan who wanted to avoid traditional brain surgery, focused ultrasound opens a new door to better quality of life.

Parkinson's patients now have another powerful option for reclaiming the everyday activities that make life meaningful.
