Three Advantages Of Mrgfus For Pd Tremor

Vlog #74 MRI Guided Focused Ultrasound For Parkinson’s Disease

MRgFUS is a noninvasive outpatient procedure. No scalpel is needed to cut skin, no drill is needed to bore a hole in the skull, and nothing is implanted in the brain. Its three main advantages for PD-related tremor are:

  • No infection risk associated with surgical thalamotomy or surgical implants
  • Test sonications to confirm precise targeting prior to full ablation
  • When successful, the results are immediately evident.
  • A few words of caution: MRgFUS is not effective in every case. As with MRgFUS for ET, treatment will be directed to the hand in which tremor is worse, since treating both hands increases the risk of side effects. Clinical studies show that some patients have short term side effect such as headaches, dizziness or nausea but these quickly resolve. However, the effect may not be durable. Patients who have suffered with significant tremor for years may experience less effective tremor control, or gradual recurrence of tremor. Finally, MRgFUS does not cure PD, nor will it have an effect on other PD-related problems.

    However, the consensus among researchers is that MRgFUS is a very promising treatment for PD-related tremor, especially as an alternative to invasive surgical procedures. If you or a loved one suffers from severe PD tremors, contact the Sperling Medical Group for more information about MRgFUS.


    Advantages Of Mrgfus For Parkinsons Disease Tremors

    In 2016, Forbes Magazine carried an article on MR-guided Focused Ultrasound for essential tremor . Citing positive results from clinical trials, the article explained that The treatment doesnt require any implants, incisions or ionizing radiationi. As the news spread, Parkinsons disease patients who also suffer from tremors wondered if MRgFUS could eliminate their tremors, too.

    Research Into Focused Ultrasound

    Focused Ultrasound Thalamotomy Promising for Reducing ...

    Ongoing research on focused ultrasound for Parkinsons is evaluating the procedure in different brain areas affected by Parkinsons, such as the subthalamic nucleus and the pallidothalamic tract. At the same time, scientists are looking at the possible benefits and safety of both-sided FUS in different targets as well as the best practices for performing this procedure.

    Researchers also are studying how ultrasound could help other Parkinsons treatments, such as antibodies against alpha-synuclein or gene therapies, get into the brain more easily and efficiently by temporarily opening the brains protective barrier.

    The device, called the ExAblate Neuro, uses focused ultrasound, pulses of ultrasound energy that can heat up tissue and destroy it. With the accompanying MRI scanner, doctors can guide the ultrasound blast, or sonication, using real-time imaging of brain anatomy, while monitoring the treatments progress.

    According to Eyal Zadicario, vice president of research and development, and director of neuro programs with the Tirat Carmel-based company, the device is being tested to target an area deep inside the brain, the thalamus, to relieve tremor, a common symptom of the neurodegenerative disease.

    This area is one of the same targets of deep-brain stimulating devices, surgically implanted, pacemaker-sized items that send frequent jolts into the brain to relieve Parkinsons symptoms, he said.

    Zadicario said they expect the study to start in the fall.

    In the study, up to 30 patients with tremor-dominant Parkinsons will be recruited and randomized between the ExAblate treatment and a control sham treatment. Patients in the sham group would then be offered to cross over for actual treatment once their leg of the study is over, Zadicario said.

    The clinical attributes of the disease are different, but the technique of the surgical procedure is similar, he told DOTmed News by phone.

    Is This A Cure For Parkinsons Disease

    Ultrasound as a Treatment for Parkinsons Symptoms

    This current research trial is investigating the safety of injecting an enzyme in conjunction with opening the BBB in the putamen, one of the key regions of the brain implicated in Parkinsons. The putamen is a key structure in controlling the brains motor circuitry.

    The hope is that this technique may be a way to open temporary access ports into the brain and allow large molecules such as enzyme therapies to enter.

    This Phase 1 clinical trial is a very early, but necessary step in this process.

    What Is Mr Guided Focused Ultrasound

    Magnetic resonance guided focused ultrasound is a non-invasive way to treat benign and malignant tumors.

    Ultrasound is a form of energy that can pass through skin, muscle, fat and other soft tissue so no incisions or inserted probes are needed. High intensity focused ultrasound pinpoints a small target and provides a therapeutic effect by raising the temperature high enough to destroy the target with no damage to surrounding tissue.

    Magnetic resonance imaging is used to guide and control the treatment, which is performed while you lie in an MR scanner. Guided by detailed images of your anatomy and the tumor, the physician is able to pinpoint, direct and continuously monitor the treatment.

    Fda Approves Focused Ultrasound For Common Parkinsons Symptoms

    The U.S. Food and Drug Administration has approved an incisionless form of brain surgery to treat advanced Parkinsons disease after successful testing at the University of Virginia School of Medicine and other sites.

    The authorization allows the use of Insightecs Exablate Neuro focused ultrasound device to treat problems with mobility, rigidity and involuntary movements, known as dyskinesias, that are common in Parkinsons. UVA is one of only 37 medical centers in the country with the capacity to offer this minimally invasive treatment, according to the Charlottesville-based Focused Ultrasound Foundation, a longtime supporter of UVAs pioneering research into the many potential applications of the technology.

    Prior to the approval, available treatments for the Parkinsons symptoms included drugs, which not all patients respond to, and invasive deep-brain surgeries.

    Focused ultrasound, in comparison, does not require incisions or cutting into the skull. Instead, the technology focuses sound waves inside the brain to interrupt faulty brain circuits, much like a magnifying glass can focus light to create heat. During the focused ultrasound procedure, doctors use magnetic-resonance imaging to peer inside the brain in real time before making any permanent changes, helping ensure patients get the best possible outcomes.

    What Neurologic Conditions Can Be Treated With Mr

    The U.S. Food and Drug Administration has approved focused ultrasound for the following conditions:

    • Essential tremor. MR-guided focused ultrasound is approved for the treatment of essential tremor that cannot be controlled with medication. Approval is for treatment of one side of the brain only. Patients must be at least 22 years of age.
    • Tremor-dominant Parkinsons disease. MR-guided focused ultrasound is approved to treat patients with Parkinsons disease whose main symptom is tremor. Patients must be at least 30 years of age.

    Use of MR-guided focused ultrasound is being explored for other neurologic conditions including the tremors associated with multiple sclerosis, epileptic seizures that cannot be controlled by other treatment approaches, other movement disorders, stroke, brain tumors and neuropathic pain. Treating these other conditions is considered experimental at this time.

    Surgical Procedure For Mrgfus

    Study Shows Use of MRI-Guided Focused Ultrasound can Treat Essential Tremor

    Conventional MRgFUS was performed at the left posteroventral GPi according to a previously described protocol.13,14 The entire procedure was performed using a 3-T MRI scanner using the Exablate 4000 device . The entire scalp was completely shaved, and a scalp nerve block was performed to prevent the experience of pain during the cooling stage.20 A Cosman-Roberts-Wells stereotactic frame was then fixed on the patients head under local anesthesia. A flexible silicone membrane with a central hole was applied to the patients head to seal the space between the head and the transducer. This space contained cool, degassed water to reduce heating of the scalp. Prior to initiation of treatment, a series of standard diagnostic MRI scans were obtained to identify the location requiring treatment. The target area of the left GPi included the following coordinates: 20 mm lateral to the midline, 34 mm anterior to the midpoint between the anterior and posterior commissures, and 34 mm inferior to the intercommissural line.

    Fast Recovery Immediate Success

    The procedure takes place under local anaesthetic and you will need a one night hospital stay afterwards. There is a period of about one month afterwards when you may notice some minor issues that gradually improve and we advise you not to drive for one month after the procedure.

    The treatment works immediately and the results are expected to be long-lasting.

    How Does The Focused Ultrasound Reduce Tremor

    For essential tremor and Parkinsons disease, over 1,000 highly focused beams of ultrasound are concentrated on a specific area in the brains thalamus. The thalamus in the brain is a relay station of motor and sensory signals. Essential tremor and Parkinsons disease cause the thalamic circuitry to become abnormal, which results in tremors. The heat from the ultrasound causes a tiny burn or lesion on the targeted spot on the thalamus. Creating the tiny burn or lesion interrupts the abnormal activity, which relieves the tremors associated with these diseases.

    Insightec Gets Europe

    AD: MRgFUS is an incision-less therapeutic treatment, which uses MRI-guided ultrasound waves to precisely target and treat areas deep inside the brain that cause movement problems.

    It sounds straightforward. However, the brain presents challenges due to the skull scattering the sound waves. By using advanced ultrasound technology in combination with real-time MRI images, we are able to refocus the energy beyond the skull and into the brain. During the treatment, we use the MRI along with an alert patient to test brain areas for accuracy by delivering a test dose, which if correct will temporarily fix the disorder. With this clinical confirmation, the full therapeutic dose is delivered, where the energy precisely creates heat to form a permanent lesion at the targeted brain area.

    The treatment is irreversible and currently offered as a unilateral treatment, meaning only one side of the brain is treated. However, there is ongoing research to assess whether a bilateral approach demonstrates appropriate safety and efficacy. This would be a staged process and based on a case-by-case basis of patient symptoms.

    Is Focused Ultrasound Right For You

    If your tremor is impacting your quality of life and medicine isnt helping, then focused ultrasound may be an option for you.

    This treatment works best for patients who:

    • Have tremor symptoms that are worse or advancing faster on one side than the other.
    • Take anti-coagulants or have other conditions that make options like deep brain stimulation dangerous. You and your doctor will decide if you should stop blood thinners before focused ultrasound.
    • Do not want to have invasive brain surgery or commit to the ongoing adjustments that deep brain stimulation requires.

    This treatment does not work for patients who:

    • Cannot have an MRI due to implanted metallic devices , body weight greater than 300 pounds, or allergies to MR contrast agent.
    • Have a high skull density ratio. About 15 percent of people have skulls too dense for this treatment.
    • Have a history of abnormal bleeding, or conditions like advanced kidney disease, unstable cardiac disease, severe high blood pressure, or certain brain problems.
    • Are unable to tolerate being still for the three-hour treatment.
    • Are pregnant.

    If You Suffer From Essential Tremor An Uncontrollable Shake In The Body Which Is Caused By Incorrect Electrical Circuits In The Brain Our Neurology Team Can Offer A Variety Of Treatment Options To Help Resolve Your Problem

    As well as utilising drug therapy, surgery or deep brain stimulation, we are now able to offer a pioneering treatment at The Lindo Wing of St Marys, known as magnetic resonance -guided focused ultrasound, which requires no surgery.

    This is a non-invasive alternative which can be used for a number of conditions, but we are the first Trust to use the technology to access the brain. MR-guided focused ultrasound technology uses an MRI to guide powerful focused ultrasound to a very small point in the body. This creates an intense local heat that destroys cells and breaks the circuit causing the tremor, but does not impact any of the unaffected parts of the brain.
