A Life Restored: How John Whitehead Found Relief From Essential Tremor
When John Whitehead first noticed his hands shaking in his early 30s, he didn’t think much of it. Working in the office of a fire department, he was responsible for sketching maps — but drawing a straight line suddenly became impossible. “My hands just wouldn’t stay still,” he recalls.
Years later, the Elk Grove, California resident learned he had essential tremor (ET) — a neurological movement disorder that causes involuntary shaking, usually in the hands. Unlike Parkinson’s disease, ET usually appears during purposeful movement, and it affects an estimated 10 million people in the United States.
For John, the condition slowly progressed. His tremors became so severe that he couldn’t write his name, drink from a cup, or even eat comfortably. “I had to carry a tablespoon everywhere because food would fall off a regular spoon,” he says. “It was embarrassing and frustrating.”
Medication didn’t help. Side effects outweighed any benefit, and daily tasks continued to grow harder. Then John learned about a cutting-edge, incisionless treatment at UCSF — and everything changed.
Discovering a New Option: High-Intensity Focused Ultrasound
John was referred to the UCSF Movement Disorders Clinic, where neurosurgeon Dr. Doris Wang explained a promising treatment called High-Intensity Focused Ultrasound (HIFU).
Unlike deep brain stimulation (DBS), which requires surgery and implanting hardware, HIFU uses targeted sound waves to destroy the tiny brain cells responsible for tremors — all without a single incision.
Using MRI guidance, Dr. Wang and neuroradiologist Dr. Leo Sugrue created a personalized treatment plan, mapping out the exact spot in John’s brain to target while avoiding surrounding structures.
During the actual procedure:
-
John remained awake
-
MRI directed focused ultrasound beams deep into the brain
-
Tremor-causing tissue was safely destroyed
-
Improvement was immediate
Patients usually return home within an hour — and John was no exception.
“It Changed My Life”
The moment the treatment ended, John could lift a water bottle and drink without spilling. When handed a pen, he wrote his name steadily for the first time in years.
“I couldn’t believe it,” he says. “It looked just like my signature on my driver’s license.”
Now back home with Millie, his wife of more than 50 years, John says the biggest change has been confidence. He feels comfortable socializing again, meeting friends, and living life without worrying about tremors distracting from every interaction.
“You don’t realize how much you avoid people until the problem is gone,” he says. “This gave me my life back.”
A Glimpse Into the Future
According to UCSF specialists, HIFU delivers 80–90% tremor reduction immediately, and long-term studies show results staying strong years later. The FDA recently approved the treatment for both sides of the brain — opening the door for even more patients to benefit.
Dr. Sugrue believes HIFU is only the beginning: “This technology is going to reshape how we treat neurological conditions,” he says.
For John Whitehead, it already has.
