Insightec’s Incisionless Focused Ultrasound Therapy Successfully Treats Downton Abbey Creator Lord Julian Fellowes for Essential Tremor

Essential tremor, considered the most common neurological movement disorder, is estimated to affect more than 60 million people worldwide.¹

MIAMI, Sept. 17, 2025 — Insightec, a global healthcare innovator pioneering the use of focused ultrasound to transform patient care, today announced that Lord Julian Fellowes, Oscar-winning screenwriter and the acclaimed creator of Downton Abbey, has undergone magnetic resonance–guided focused ultrasound (MR-guided focused ultrasound) to treat essential tremor (ET). He has lived with the condition for more than a decade and experienced meaningful improvement in his tremor following treatment.

Essential tremor is a progressive neurological movement disorder that causes involuntary shaking — commonly of the hands and arms — and can also affect the head, voice and other parts of the body.³ The condition can significantly impact daily activities and quality of life; over 40% of people with ET report that it affects their ability to socialize and continue hobbies.⁴

Ahead of his treatment, Lord Fellowes described losing his handwriting because of ET: “I’m a writer and, of course, that means I have to type, because one of the losses has been handwriting. Writing by hand is now impossible for me.” Driven by his personal experience, Lord Fellowes serves as Honorary President of the National Tremor Foundation, which recently hosted a UK parliamentary meeting to raise awareness of the unmet needs of the more than one million people affected by ET across the UK.²

To share his experience, Fellowes partnered with Insightec on a film that highlights the impact of ET on his life, particularly his ability to write — central to his personal life and professional career — and demonstrates how focused ultrasound, a safe, incisionless treatment, helped him restore it. “I’ve got the pleasure of being able to write again,” Lord Fellowes reflected. “If I were talking to someone who was considering having the treatment, I would say to them that, for me, my life feels much more normal again. I haven’t regretted it for one second.”

Insightec’s focused ultrasound technology has now been used to treat more than 25,000 patients worldwide. The procedure is typically performed on an outpatient basis and treats one side of the brain at a time. Long-term follow-up from an Insightec-sponsored clinical trial showed that unilateral MR-guided focused ultrasound for essential tremor provided sustained symptom relief, with an average 73.1% improvement in tremor severity at five years.⁷

“Essential tremor is often misunderstood and its impact underestimated,” said Professor Dipankar Nandi MRCS Ed, FRCS (SN), Consultant Neurosurgeon, Imperial College Healthcare NHS Trust. “MR-guided focused ultrasound is a proven, safe, and effective incisionless option for patients who do not find relief with medication. By sharing Julian Fellowes’ story, we hope to raise visibility of the condition and encourage broader access to innovative treatments for movement disorders.”

This successful outcome for patients like Lord Fellowes underscores the technology’s potential. “Julian Fellowes’ story shines a light on what many people living with essential tremor experience every day: the frustration of losing simple abilities that most of us take for granted,” said Maurice R. Ferré, MD, CEO and Chairman of Insightec. “Insightec’s focused ultrasound offers patients a safe, incisionless option that can truly change lives, and we are proud to see it restoring confidence and independence for people like Lord Fellowes.”

“Downton Abbey: The Grand Finale,” written by Fellowes, had its global theatrical premiere this past weekend. For more information on essential tremor and to learn more about focused ultrasound as a therapy option, visit the National Tremor Foundation website.
