RI Hospital Performs Incision-Less Brain Surgery

Neurosurgeons at the Norman Prince Neurosciences Institute are now offering an innovative, incision-less brain surgery that aims to treat patients suffering from  tremors – and it’s available here in Rhode Island.

“The big obstacle was basically being able to get the energy through the skull in such a way that it could be focused to perform very precise neurosurgery. This new device has that capability,” explains Dr. Wael Asaad, Neurosurgeon at Rhode Island Hospital. The ultrasound technology, guided by magnetic resonance imaging (MRI), specifically targets the area of the brain that causes tremors in patients that suffer from movement disorders such as Parkinson’s Disease or essential tremors. The first patient, David Mossberg, underwent the non-invasive treatment on July 30th at Rhode Island Hospital. “I have Essential Tremor. The treatment was fabulous. The tremor is now completely gone in my right hand. I can now hold a fork, soup spoon, and a coffee mug perfectly steady. Also, I was having a very hard time writing. My handwriting is as good now as when I was in high school.”
