In a medical breakthrough that sounds almost too good to be true, 72-year-old Orlando Avendaño from Palm Beach, Florida, has experienced what many with essential tremor only dream of: a complete and immediate reversal of his symptoms. After more than three decades of struggling with everyday tasks—writing, drinking from a cup, and even eating—Avendaño’s debilitating hand tremor is gone. And remarkably, the treatment took only a few hours and was entirely covered by Medicare.
Essential tremor, a neurological condition that affects millions globally, is often confused with Parkinson’s disease but is distinct in its characteristics. It most commonly affects the hands and can progressively worsen over time. In Avendaño’s case, the tremor had robbed him of independence in even the most basic tasks. He had resorted to using large spoons to mask the tremor while eating and had to use both hands just to drink water.
But that changed at Delray Medical Center in Florida, where Avendaño underwent a procedure that uses focused ultrasound technology—similar in principle to the sound waves used in fetal imaging or bat echolocation. The tool behind this innovation is a headgear device known as Neuravive, developed by Insightec, a pioneer in focused ultrasound technology. This non-invasive device is guided by real-time magnetic resonance imaging (MRI) to pinpoint the exact source of the tremor in the brain.
“It’s probably the most wonderful thing,” said Dr. Lloyd Zucker, the neurosurgeon who performed the procedure. “I’ve been doing it for years, and as you can see as I start to smile, you can’t take this away, when you see the patients and the families and what it does for them.”
The process begins early in the day. The patient’s head is secured in the Neuravive headgear and they are slid into an MRI machine. From there, Dr. Zucker identifies the precise location in the thalamus—the brain area responsible for the tremor. Then, with targeted bursts of ultrasound, a small lesion is created. This precise ablation interrupts the circuit causing the tremor, effectively “knocking it out” without needing a scalpel or sedation.
Minutes after the lesion was made, Avendaño’s hand was steady for the first time in over 30 years. Captured by NBC 6 in a moving segment, Avendaño raised his hand, visibly shocked and elated, and exclaimed, “Oh my God, it’s unbelievable.” For Dr. Zucker, it was a moment he described as a “magic trick,” adding, “He’ll go home, and he’s going to sit there tonight at dinner, and all those things he couldn’t do, he’s gonna be doing. How do you put an adjective on that one? You can’t.”
Beyond its stunning effectiveness, what makes this procedure even more accessible is its coverage. According to the Delray Medical Center and Insightec, the focused ultrasound treatment is not only covered by Medicare but is also included in 22 different Blue Cross Blue Shield plans. Currently, there are 79 centers across the United States offering the treatment under full Medicare coverage, making it available to many elderly patients who would otherwise be left with limited options such as medication or invasive surgery.
The technology represents a leap forward in non-invasive neurosurgery and patient quality of life. With no need for general anesthesia or post-operative recovery, patients like Avendaño can return to their daily lives almost immediately, free from a condition that once seemed inescapable.
For those suffering from essential tremor, the message from Florida is clear: hope is not hypothetical—it’s real, and it’s here.
