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 worldwide¹

MIAMI, Sept. 17, 2025 /CNW/ -- Insightec, a global healthcare innovator pioneering the use of focused ultrasound to transform patient care, today announced that Lord Julian Fellowes, Oscar-winning screen writer and 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 over a decade and experienced meaningful improvement in his tremor following treatment.

ET is a debilitating and progressive neurological movement disorder that causes involuntary shaking, commonly of the hands and arms, but it can also affect the head, voice, and other parts of the body.³ The condition can significantly impact daily activities and quality of life, including the ability to work, with over 40% saying it impacts their ability to socialise and continue hobbies.⁴

Ahead of his treatment, Lord Fellowes spoke of losing his handwriting from 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 significant unmet needs of more than one million people affected by ET across the UK.² Although often being misdiagnosed, ET is the most common neurological movement disorder, estimated to be eight to ten times more prevalent than Parkinson's disease.⁴ Yet awareness and therapy uptake remain low across movement disorders, with 97% of eligible patients not receiving advanced therapies.⁶

To share his experience, Fellowes partnered with Insightec on a film that highlights the impact of ET on Fellowes' life, particularly his ability to write – which is both 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."

To date, Insightec's focused ultrasound technology has been used to treat more than 25,000 patients worldwide. The procedure is typically performed on an outpatient basis, treating one side of the brain at a time. Long-term follow-up from the Insightec sponsored clinical trial revealed that unilateral MR-guided focused ultrasound for essential tremor provided sustained symptom relief, with observed patients showing a 73.1% average 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 is a testament to the technology's impact, a mission that Insightec's leadership is dedicated to advancing globally.

"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," explained 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.
