Is Focused Ultrasound Safe? Risks, Side Effects & Long-Term Outcomes Explained
Focused Ultrasound Treatment is a breakthrough non-invasive method for patients with neurological movement disorders like Essential Tremor and Tremor of PD, and is slowly being adopted by hospitals across India. Naturally, patients and their families are concerned about the safety of Focused Ultrasound.
Treating patients with the most complex organ (the brain) is always intimidating. How much more, if patients get to hear and understand that it involves ultrasound energy, MRI, and brain targeting? Even if the results of ultrasound-guided Focused Ultrasound (MRgFUS) hold great promise for a certain group of patients, it is imperative to know what collateral damage may be incurred, and what side effects and long-term results are to be expected before opting for any treatment.
In this guide, we will try to answer what Focused Ultrasound is, what symptoms and diagnostics are correlated, how safe this procedure may be, and what patients may expect from the Focused Ultrasound treatment in the long term.
Minimal Invasive Focused Ultrasound Treatment – What is it?
MRgFUS is a treatment that is a brain surgery with ultrasound energy, which is minimally invasive, and allows the surgeon to eradicate the part of the brain responsible for the aberrant movements and symptoms.
MRI is used in this procedure to guide and take real-time images of the brain while the doctor is selectively treating the brain, thus eliminating the need for any surgical cuts or openings.
Potential Focused Ultrasound Treatment Symptoms
Patients often seek out advice regarding MRgFUS when their symptoms are severe enough to impact their daily tasks.
Essential Tremor Symptoms
- Shaking while eating or writing
- Difficulty with controlling your hands when carrying items
- Shaking when speaking
- Shaking while resting
- Shaking while performing tasks
Parkinson’s Disease Symptoms
- Shaking while resting
- Stiffness of the muscles
- Slowed movement
- Difficulty while walking
- Problems with stability
- Reduced facial expressions
When medications stop providing enough relief, neurologists may consider advanced treatment options such as Focused Ultrasound.
How Is The Diagnosis Performed?
Making an accurate diagnosis is of the utmost importance when suggesting treatment options.
Tasks For the Neurologist
Checking symptoms like:
- Severity of the tremor and loss of balance
- Stiffness of the muscles
- Difficulty performing daily tasks
- Your response to medications
MRI of the Brain
MRI is useful for identifying key treatment targets and diagnosing other neurological disorders.
CT Scan of the Skull
This is a scan of the skull to help assess the effectiveness of ultrasound beams. Skull density is critical to the safety and effectiveness of treatment.
General Health Assessment
Your docs may assess your:
- Heart
- Blood pressure
- Diabetes
- General health condition
With Focused Ultrasound, the safety and effectiveness can be compromised if the patient isn’t carefully selected.
One major benefit is that the treatment largely avoids the threats associated with normal brain surgery, since there are:
- No incisions made
- No glue or stitches
- No devices left in the brain
- No general anaesthetic in most situations
Because the brain is monitored in real time with MRI, it brings more accuracy to the surgery and avoids most of the damage brain surgery would normally cause to other tissues.
However, there are still risks associated with MRgFUS.
Focused Ultrasound Side Effects
There are a few side effects, but they typically go away slowly after the treatment.
Short-Term Side Effects Can Include:
- Mild Headache
- Tingling and Numbness
- Balance Problem
- Dizziness
- Nausea
- Tiredness
It has been noted that people have had changes with their walking after, but that it is typically mild and unsteady.
These symptoms usually go away in a few days to a few weeks.
Risks of Focused Ultrasound
Patients should also understand that some of these risks can cause serious consequences in rare cases.
Risk with Focused Ultrasound can include:
Changes in Levels of Coordination or Speech
Because certain brain areas are targeted in Focused Ultrasound, a few patients may experience:
- Weakness
- Slurred speech
- Decreased levels of coordination
- Balance Issues
Children can also have some issues with balancing and walking after Focused Ultrasound.
Not all symptoms will improve.
Some people will not have their tremors go away. Other people may still need help with medication.
What Makes A Treatment Safer and More Effective
There are multiple factors that come into focus when determining the safety and effectiveness of FUS.
What Patients Are Right For Surgery
Not everyone is a candidate for MRgFUS. The goal for us is to lower risks for patients and improve treatment outcomes.
Coaches
The fancier the place that has more advanced MRI-guided and Treatment Systems, the safer and more sophisticated the MRI operations are.
Types of Systems
The more advanced the MRI-guided systems, the better the treatment precision and the system’s monitoring.
Understanding
Correct systems monitoring treatment for a certain disease and true treatment.
Long-Term Outcomes of FUS
Most patients see a significant tremor improvement in the long term.
The Long-Term impacts for everyone may have:
- The capability for a better quality
- More independent
- The easier daily activities
- Reduced medication dependence in patients
- Living a better quality of life
Most people with Essential Tremor see a more manageable tremor, and some patients with Parkinson’s, and more importantly, tremor-dominant.
The main goal of the treatment is to manage the tremor symptoms and not eliminate the disease or its progression.
The Focused Ultrasound Treatment uses
How Long is the Surgery
- The quicker the surgery is, the more patients.
- Most return
- Daily are the activities.
- That
- Most people follow up to see the symptoms.
Conclusion
MR-guided Focused Ultrasound makes previously unthinkable high-tech and less harmful options available for people with movement disorders such as Essential Tremor or the symptoms of tremor in Parkinson’s disease. This option decreases the risks of users having issues with tremor control and the inconvenience of surgery, as well as the risk of a poorer quality of life.
Like all temporal treatments, Focused Ultrasound must be understood in its potential scope of issues, risks, and long-term usefulness. Diagnosis and the choice of the correct patients are, in this case, inseparable from the control of risks, as are all experienced aspects of medicine.
Focused Ultrasound as a treatment option should definitely be considered by people with tremor and/or worsening movement issues.
Frequently Asked Questions
1. Is Focused Ultrasound as safe as a surgery of this type?
Focus and the potential of Focused Ultrasound are completely different from more traditional surgery. No incisions are needed.
2. Is Focused Ultrasound a temporal treatment?
Focus and Focused Ultrasound have both temporal and permanent aspects. Some side effects will get better as time goes by, but the best option is to persist with nearness.
3. Is Focused Ultrasound a complete response to tremors?
The treatment is great, but certain patients will continue to be in need of supplementary care and medications. Some patients will have to continue nursing care.
