High-Intensity Focused Ultrasound (HIFU) Treatment

Revolutionary Non-Invasive Tremor Treatment Without Surgery

If you’re struggling with essential tremor or Parkinson’s disease tremors that interfere with your daily life, High-Intensity Focused Ultrasound (HIFU) offers a groundbreaking solution. At Morrison Clinic™, we utilize this FDA-approved, non-invasive technology to provide precise tremor relief without the need for traditional brain surgery or implanted devices.

What is HIFU Treatment?

High-Intensity Focused Ultrasound (HIFU), also known as MR-guided focused ultrasound (MRgFUS), is an advanced therapeutic technology that uses focused ultrasound waves to target specific areas of the brain responsible for tremors. This innovative approach allows our specialists to interrupt the abnormal brain signals that cause uncontrolled shaking, providing significant symptom relief without making any incisions.

The procedure represents a paradigm shift in neurological treatment, offering the precision of traditional neurosurgery without the associated risks and recovery time. HIFU has been rigorously studied and is FDA-approved for treating essential tremor and tremor-dominant Parkinson’s disease, with clinical trials demonstrating sustained improvement in over 80% of patients.

The procedure combines two cutting-edge technologies:

  • Focused ultrasound energy that precisely targets deep brain tissue with sub-millimeter accuracy
  • Real-time MRI guidance that allows for accurate targeting, continuous monitoring, and immediate treatment verification

This dual-technology approach ensures that treatment is delivered with unprecedented precision while maintaining the highest safety standards.

How HIFU Works

During HIFU treatment, multiple ultrasound beams are focused on a specific target in the thalamus region of your brain—the area where tremor signals originate. The principle is similar to using a magnifying glass to focus sunlight: while individual ultrasound beams pass harmlessly through tissue, their convergence at the focal point creates a therapeutic effect.

The focused ultrasound energy creates a small, precise lesion in the targeted brain tissue, interrupting the abnormal neural pathways that cause tremors. This targeted approach allows for symptom relief while preserving surrounding healthy brain tissue.

Real-Time Monitoring and Adjustment

Throughout the procedure, advanced MRI thermometry allows our team to:

  • Monitor tissue temperature in real-time
  • Verify lesion formation and size
  • Assess immediate treatment response
  • Make adjustments to optimize outcomes
  • Ensure patient safety throughout the process

This real-time feedback system enables our specialists to customize treatment parameters for each individual patient, maximizing therapeutic benefit while minimizing any potential side effects.

Conditions Treated with HIFU

Our neurological specialists use HIFU to treat various tremor-related conditions, with particular success in the following areas:

Primary Conditions

  • Essential Tremor – The most common movement disorder affecting hands, arms, and sometimes head and voice, particularly when performing specific tasks or holding positions
  • Tremor-Dominant Parkinson’s Disease – Specifically targeting the tremor component of Parkinson’s disease while preserving other motor functions
  • Medication-Resistant Tremor – For patients who haven’t responded adequately to traditional therapies or experience intolerable side effects
  • Failed Deep Brain Stimulation – As an alternative for patients who are not candidates for or have not succeeded with DBS therapy

Special Considerations

HIFU may also benefit patients with:

  • Bilateral tremors – Though typically treated one side at a time
  • Functional tremors – In carefully selected cases where organic causes have been ruled out
  • Secondary tremors – Related to other neurological conditions affecting the thalamus
  • Medication-induced tremors – Particularly those caused by certain psychiatric medications

Treatment Success Rates

Clinical studies demonstrate impressive outcomes:

  • 80-90% of patients experience significant tremor reduction
  • 70-80% maintain improvement at 2-year follow-up
  • Most patients can reduce or eliminate tremor medications
  • Quality of life improvements are sustained long-term

Frequently Asked Questions

Is HIFU painful? Most patients report minimal discomfort during the procedure. Some may experience mild sensations such as warmth, tingling, or brief headaches during energy delivery, but these are generally well-tolerated. We provide anti-anxiety medication and frequent comfort checks throughout the treatment.

How long do results last? Clinical studies show that tremor improvement from HIFU can be long-lasting, with many patients experiencing sustained benefits for years after treatment. Research indicates that 70-80% of patients maintain significant improvement at 2-year follow-up, with some studies showing benefit lasting 5+ years.

Can the procedure be repeated? In some cases, HIFU can be repeated if tremors recur or if initial treatment provides partial benefit. However, repeat treatments are carefully evaluated on a case-by-case basis, considering factors such as previous response, current symptoms, and anatomical considerations.

Will I need to continue medications? Many patients can significantly reduce or eliminate tremor medications after successful HIFU treatment. However, this process should be gradual and always supervised by your neurologist. Some patients may continue low-dose medications for optimal tremor control.

What are the potential side effects? Common temporary side effects may include:

  • Mild headache (resolves within 24-48 hours)
  • Slight numbness or tingling in the treated hand
  • Mild balance issues (typically resolve within days)
  • Temporary fatigue

Serious complications are rare but can include:

  • Permanent weakness or numbness
  • Speech difficulties
  • Balance problems
  • Cognitive changes

How does HIFU compare to deep brain stimulation (DBS)? HIFU offers several advantages over DBS:

  • No surgery or implanted hardware
  • Immediate results without device programming
  • No risk of infection or hardware malfunction
  • No need for battery replacements
  • Can be performed as an outpatient procedure

However, DBS may be preferred for:

  • Patients who want reversible treatment
  • Those with bilateral tremors requiring treatment of both sides
  • Patients with multiple Parkinson’s symptoms beyond tremor

Am I too old for HIFU treatment? Age alone is not a contraindication for HIFU. We’ve successfully treated patients in their 80s and 90s. The key factors are overall health status, cognitive function, and ability to cooperate during the procedure.

What should I expect in terms of recovery time? Most patients return to normal activities within 24-48 hours. Unlike traditional brain surgery, there are no incisions to heal, no risk of infection, and no need for extended recovery. You may experience some fatigue for a few days, which is normal after any medical procedure.

Will my insurance cover HIFU treatment? HIFU for essential tremor and Parkinson’s disease is FDA-approved and increasingly covered by insurance providers, including Medicare. Our financial counselors work with patients to verify coverage and explore payment options.

How do I know if I’m a good candidate? The best way to determine candidacy is through a comprehensive evaluation by our movement disorder specialists. This includes medical history review, neurological examination, tremor assessment, and imaging studies. We’ll discuss all treatment options and help you make an informed decision.
