Preparing for Focused Ultrasound Treatment: What Patients Need to Know
Tremors can make things like writing, eating, or even using a cellphone painful, difficult, and frustrating. For some patients, medication can decrease symptoms, but for many, the medication doesn’t work or the tremors still negatively impact their quality of life.
MR-guided Focused Ultrasound (MRgFUS) is a new treatment option for essential tremors. It is a non-invasive procedure, which appeals to a lot of patients, but to have the best experience possible, patients should be aware of what to expect before, during, and after the procedure.
This guide has everything you need to know when preparing for Focused Ultrasound treatment, including the benefits and risks, what to expect for diagnosis, symptoms, treatment prep, and recovery.
Defining Essential Tremor
Essential tremor is a common neurological movement disorder, but it is specifically a rhythmic, involuntary, and oscillatory movement. Most frequently, it affects the arms and hands, but other body parts can be affected.
Essential tremor is frequently misdiagnosed as Parkinson’s disease, but Parkinson’s tremors occur during a state of rest. At the same time, essential tremors occur during and after movement.
Essential tremor can be a social and physical handicap for many patients and is often classified as mild or severe.
Essential Tremor Symptoms
Symptoms can be socially hindering and frequently worsen over time, and, unfortunately, there is no known cure. We will discuss a treatment option for you, MR-guided Focused Ultrasound (MRgFUS), shortly.
Identifying Essential Tremor
These symptoms may be a sign of essential tremor:
- Difficulties with hand coordination
- Disadvantageous writing
- Shaking or trembling during eating or drinking
- Inability to manipulate tools or electronic devices
- Shaking head
- Voice tremors
Symptoms of essential tremor may be more noticeable with fatigue or stress.
When symptoms of essential tremors are more noticeable with fatigue or stress, advanced treatment options may be available when medication is no longer effective.
What Is the Diagnosis Process for Essential Tremor?
Essentials for the Diagnosis of Tremors
Medical History
Neurologists may ask about:
- The time of onset of tremors
- Family history of tremors
- How essential tremors affect daily life
- Treatments with medication that have been attempted
Neurological Examination
A neurologist may perform a detailed assessment that includes:
- Tremor patterning and observation
- Coordination/manipulation assessment
- Assessment of strength
- Reflexes
- Balance/posture
Imaging and Other Assessments
MRI and other imaging may be done to assess tremors and rule out other causes of tremors, and to assess if the patient is a candidate for treatment.
What Is the Treatment of Focused Ultrasound?
With MRI-Guided Focused Ultrasound, highly focused ultrasound waves are used to target a small and specific area of the brain that produces and stimulates tremors.
The treatment is completely guided by MRI, in which the neurologist is able to focus on the pathway of the brain that is of interest, without any other invasive measures such as surgery.
The attempt to interrupt the abnormal signalling that is responsible for the tremors is accomplished by this treatment.
Focused Ultrasound is also an unconventional brain surgery in that it does not require any kind of implant, incision, or general anesthesia.
Who Is a Likely Candidate for Focused Ultrasound?
Focused Ultrasound may be appropriate for people who:
- Have a moderate to severe essential tremor
- Have significant tremors that interfere with daily living
- Continue to have significant symptoms despite taking tremor-reducing medications
- Are evaluated and deemed an acceptable risk for the procedure
Tremors are very common, and not all patients who present with tremors are candidates for Focused Ultrasound.
What Is the Preparation for the Procedure?
There is a lot you will need to do to get ready long before the date of the procedure.
What Medical Assessments Are Done?
Focused Ultrasound is only performed after an extensive assessment is completed by a neurologist and the treatment team.
The assessments may include the following:
- Neurological assessments
- MRI
- Assessment of your medications and medication history
- Ultrasound of your abdomen (if required)
What Is the Focused Ultrasound Procedure?
Bring your questions about Focused Ultrasound, especially about the:
- Benefits you may see
- Risks of the procedure
- Recovery from the procedure
- Other treatment options available
This procedure is performed after a lot of information is provided and is meant to calm the patient because it is an invasive procedure.
What Is Done to Your Medications?
Some medications may be adjusted to make you more comfortable.
Never adjust your medications on your own.
- What medications are focused on
- Relaxation techniques
What Are the Directions You Are Given Pre-Procedure?
It is completely normal to be anxious before a procedure. The treatment team will listen and answer your questions.
What Happens on the Date of the Procedure?
You will be alert for much of the procedure.
What Preparation Is Completed on Your Head?
MRI Guidance
While the MRI scanner captures images, the medical team identifies the target area within the brain.
Delivery of Ultrasound Energy
During the process, the medical team monitors the patient’s reactions and responses.
The treatment even allows patients to perform tasks so the team can measure the extent of the improvement of the tremors.
The treatment can even last a couple of hours.
Benefits of Focused Ultrasound
For the patients who can receive it, Focused Ultrasound has a lot of great advantages and benefits.
For example:
- There are no cuts on the body
- Nothing is left inside the body
- Recovery happens very quickly
- The hospital stay is shorter
- There is an almost instant improvement in tremor symptoms
- There is a much lower chance of infection when compared to traditional surgery
Because of all of these positive traits, it is a great option for a lot of patients.
Potential Risks and Side Effects
All medical procedures have some level of risk, and Focused Ultrasound is no different.
Some of the possible side effects are:
- Temporary loss of feeling or a tingling sensation
- Feeling unsteady or off balance
- Dizziness
- A mild headache
- Feeling like you can’t walk
- Talking may change, but that is a very rare side effect
Patients need to make sure that they are aware of all of the possible side effects, and they should talk to their treatment team about their concerns.
Recovery After Focused Ultrasound
Compared to traditional brain surgery, recovery is much faster.
Immediately After Treatment
Patients will stay in the hospital for a few hours so that medical staff can monitor them and make sure that there are no problems.
Returning Home
A lot of people can leave the hospital the day after the surgery.
Scheduled Follow-Up Appointments
The scheduled appointments are a time for medical staff to check on the patients and their symptoms to make sure that there are no problems and to address any that may have come up.
Patients return to their typical routines over the following days and weeks.
Setting Realistic Expectations
Focused Ultrasound is successful in considerably diminishing tremors. However, understand that there is no cure for essential tremor.
Focused Ultrasound aims to eliminate or reduce symptoms and improve quality of life. Because each person is unique, the results of the procedure will vary. Many cases still require regular medical monitoring.
Conclusion
Focused Ultrasound is a tremendous advancement in the therapy options for people who have unmanageable essential tremor. It is a good option for patients who are carefully chosen because it has a shorter recovery time and a greater likelihood of improving symptoms more immediately when compared to other therapies.
Healing is a combination of many factors. A patient will have more realistic recovery expectations when they know their diagnosis and the treatment process, the possible benefits, and the possible risks.
Focused Ultrasound is not a good option for everyone. If a person is interested, they need to have a thorough consultation with a neurologist who has experience with the therapy.
FAQs
1. Is surgery necessary for Focused Ultrasound?
No. There are no incisions or devices that are implanted with Focused Ultrasound.
2. What is the recovery time for Focused Ultrasound?
Many patients return to their normal routine in a few days. Focused Ultrasound recovery varies from person to person.
3. Will Focused Ultrasound eliminate essential tremor?
Focused Ultrasound is not a cure for essential tremor. It is therapy that will lessen tremors and improve a patient’s quality of life.
