Individuals With Pd At Risk For Nursing Home Placement

MRI-guided focused ultrasound for Parkinsons disease

In clinical practice, a person with PD is frequently housed in a nursing home when nonmotor symptoms such as hallucinations, psychosis, and dementia, as well as motor symptoms progress to the point where they interfere with When an individual is diagnosed with Parkinsons disease, their long-term progess is heavily influenced by their stage of the disease, their overall health, and their age. Almost all people suffering from Parkinsons disease have a normal or near-normal life expectancy. Despite the fact that Parkinsons disease is still a serious and disabling illness, people who suffer from it should always consult with their healthcare providers about how to manage their symptoms and take care of their health.

Am I A Candidate For Focused Ultrasound Treatment

You must have a confirmed diagnosis of essential tremor or tremor dominant Parkinsons disease to be referred for an MR-guided focused ultrasound. Your doctors will also want to be sure you have tried at least two medications and found that they do not help you and/or have undesirable side effects. The severity of your tremor and your overall health will be evaluated as part of the evaluation process.

Patients will need to undergo a CT scan to determine if they are candidates for treatment. You must be at least 22 years old. Since the procedure is done in an MRI scanner, there is a weight limit, generally in the range of 350 lbs.

You may not be able to have this treatment if you:

  • If you have allergies to contrast dye used during MRI imaging.
  • If you have any kind of metallic implants, such as pacemakers, neurostimulators, spine or bone fixation devices, total joints, metal clips, screws, etc. you may not be a candidate. Any metallic implants must be non-magnetic, so you won’t be injured by the MRI’s strong magnetic field.
  • Not able or unwilling to tolerate the required prolonged stationary position during treatment .
  • Health-related issues such as a recent myocardial infarction , congestive heart failure , unstable angina pectoris , or spinal conditions may be issues that you should discuss with your doctor.
  • Have extensive scarring on the scalp
  • Have skull tumors
  • If you have an active infection or severe hematological, neurological, or other uncontrolled diseases.

Are You Ready To Get Started

The most common side effects include:

  • Temporary numbness and tingling in the lips or fingertips
  • Temporary unsteadiness and balance problems
  • Temporary speech or swallowing problems

These side effects sometimes start several days or weeks after treatment.

If you have additional questions, please email .

The longer term risks and complications include:

  • Tremor could return months or years later
  • Tremor might not improve at all
  • Muscle weakness, unsteadiness, sensory loss, or numbness or tingling in fingers or other areas of the body

Our medical team will conduct a complete assessment of your condition, and will then discuss whether you are a candidate for this or other treatment options .

Generally, MR-guided focused ultrasound may be an option if you have:

  • A confirmed diagnosis of tremor-dominant Parkinsons disease or essential tremor
  • Tremor that is inadequately relieved by medications
  • Tremor that limits your ability to perform daily activities

Clinical Outcomes And Adverse Events Of Mrgfus

Ventral intermediate

In a study by Bond et al., 20 patients were randomized to focus ultrasound unilateral VIM thalamotomy versus 7 patients to the sham procedure for patients with medically refractory tremor-dominant PD. Hand tremor, as measured with the Clinical Rating Scale for Tremor A+B subscores in the on-medication state, improved by 62% at 3 months. Total CRST scores improved by 44% at 3 months. The most common procedure-related AEs for all patients were finger and orofacial paresthesia. Two patients had persistent hemiparesis, and one patient had persistent mild ataxia .

Globus pallidus internus

A multicenter open-label trial investigated the efficacy and safety of MRgFUS ablation of the GPi for PD patients exhibiting levodopa responsiveness, motor fluctuations, and asymmetrical motor signs. There was a 44.5% improvement in the off-medication UPDRS-III score from baseline value at 3 months and a 45.2% improvement at 12 months. The UPDRS-IV score was used to assess the motor complications of PD. The baseline pretreatment value was reduced by 42% at 3 months, and this improvement was maintained at 12 months. Twenty persistent AEs were reported, including fine motor difficulties, dysarthria, and balance difficulties .

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.

How Can I Be Assessed For Suitability For This Treatment

Patients with various types of tremor, as well as Parkinsons Disease and dystonia, may be assessed for suitability for Neuravive.

Typically the assessment includes:

  • Diagnostic confirmation of the type of movement disorder
  • Measurement of skull density on CT, and brain morphology on MRI
  • Assessment with the standard rating scales
  • Consideration of quality of life issues
  • Assessment of other health problems which may be relevant

The assessment team includes a neurologist, neurosurgeon, neuroradiologist, and sometimes a rehabilitation physician and neuropsychologist.

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.

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.

Ld: Thank You For Allowing Our Mutual Friend To Introduce Us And For Agreeing To Answer Some Questions Most Patients Are Familiar With Deep Brain Stimulation As A Parkinsons Treatment But What Is Mrgfus

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.

First Hospital Based Focused Ultrasound Incisionless Procedure For Parkinsons & Essential Tremors In The Region Takes Place At Delray Medical Center

Parkinsons Disease Brain Scan

Dr. Lloyd Zucker, neurosurgeon and medical director of neurosurgery, completes first case

Delray Beach, FL Delray Medical Center is now the first hospital in the region to treat a patient with the new MR-guided focused ultrasound by INSIGHTEC. This technology is a scalpel-free treatment for essential tremor and medication-refractory tremor-dominant Parkinsons disease. This device uses sound wave energy to treat brain tissue as the source of the tremor and there is no surgical incision or anesthesia necessary.

I am honored to be able to not only treat the first patient at Delray Medical Center with this new groundbreaking procedure, but the first in any hospital in the region. We are now able to give those who suffer from this disease a chance to get back to living their lives, and pursuing their daily activities, said Dr. Lloyd Zucker, medical director of neurosurgery for Delray Medical Center. We are at an exciting time in medicine when it comes to treating neuro-disorders, and this technology is a game changer for patients who have suffered from Parkinsons disease.

The MR-guided focused ultrasound combines two technologies, magnetic resonance imaging , which pinpoints the exact location in the brain responsible for the tremor, and ultrasound, which precisely delivers over 1,000 highly focused beams of acoustic energy at that exact location without damaging any surrounding brain tissue.

Some of the benefits to this technology include:

How Do I Know If I Am Eligible For Treatment

Your doctor is the best person to ask about this. He or she will be able to tell you if you are a suitable candidate. In general, people who cannot go into an MRI will not be able to go through the treatment – this includes patients with metallic implants, patients who are claustrophobic and patients who are allergic to contrast agents – a dye used during MR imaging, patients who are over 300 lbs and patients who are under 22 years of age.

  • If you have any kind of metallic implants, such as pacemakers, neurostimulators, spine or bone fixation devices, total joints, metal clips, screws, etc., you may not be a candidate. Any metallic implants must be non-magnetic to prevent injury to the patient from the MRs strong magnetic field.
  • If you are not generally healthy enough to withstand the treatment and lie still in the same position for approximately 3 hours, you may not be a suitable candidate for this treatment.
  • If you have had a recent myocardial infarction or have congestive heart failure , unstable angina pectoris , or spinal conditions, are you should discuss these issues with your doctor.
  • If you have extensive scarring on the scalp, you may not be a good candidate.
  • If you have any tumors inside the skull, you may not be a good candidate.
  • If you are on dialysis, you may not be a good candidate.
  • If you have an active infection or severe hematological, neurological or other uncontrolled disease, you may not be a good candidate.

Is Focused Ultrasound Right For Your Essential Tremor

Medication like beta blockers and deep brain stimulation are traditional treatments for essential tremor symptoms.

However, you may build a tolerance to your medication over time, and deep brain stimulation, which also involves the implantation of a pacemaker, requires additional surgery. These are some reasons why FUS may be a better option for you.

With the new technology, clinicians direct ultrasound waves to a brain structure called the globus pallidus, which helps regulate voluntary movement, to destroy damaged tissue, decreasing the uncontrolled movements that characterize Parkinsons disease.

Doctors use magnetic resonance imaging to create a temperature map of the brain, giving them a real-time picture of the region they want to hit with the sound waves. They then raise the energy, directly targeting that area of the brain to destroy the tissue.

Patients are awake and alert the entire time in the MRI scanner, enabling them to give clinicians constant feedback. They are fitted with a helmet through which the energy is converted into sound waves, which are then targeted to the globus pallidus. The approach is noninvasive, meaning there is no surgery or radiation treatment involved.

Current therapies to lessen movement and coordination problems in Parkinsons patients include levodopa , which is the most common. Patients with advanced Parkinsons may undergo surgery, known as deep brain stimulation, to implant micro-electrodes in the brain that help control tremors, rigidity and dyskinesia .

For people with Parkinsons disease and other movement disorders such as essential tremor, focused ultrasound is an appealing alternative to deep brain stimulation because it does not involve more invasive surgery, said Paul S. Fishman, MD, PhD, professor of neurology at UMSOM and a neurologist at UMMC.
