Focused Ultrasound vs Medication for Tremors When Should You Consider Advanced Treatment?
Tremors can gradually impact virtually all aspects of your daily life. Simple tasks with a mobile phone, signing a paper, or buttoning a shirt can become incredibly frustrating and even impossible. For the majority of individuals suffering from Essential Tremor and Parkinson’s, pharmacotherapy is the initial treatment of choice. However, not every individual can continue to respond to the treatment long term.
Due to the progressive nature of the disease, the majority of families and patients start to seek other options. MR-guided Focused Ultrasound (MRgFUS) is one of the options. This leads to important questions: when can you make the switch from medication to Focused Ultrasound treatment?
There are several considerations when answering this question, including quality of life, severity of the symptoms and overall health of the individual.
The following will provide some information on the various symptoms and diagnosis stemming from Tremors. Furthermore, we will provide information on treatment options and factors physicians consider when recommending Focused Ultrasound.
What are tremors?
Tremors or involuntary shaking can occur in the majority of the body, with the exception of the trunk. The hands, legs, and even the voice are often impacted.
Some of the most common causes of tremors are:
- Essential Tremor
- Parkinson’s
Both of these are considered neurodegenerative diseases. Both cause tremors, but do not consider the same disease. Therefore, they require different treatment regimes.
Symptoms of Essential Tremor
Essential Tremor is characterized by an action-based tremor, meaning it is often triggered by the executed task.
Symptoms Include:
- Tremors while writing and when holding objects
- Shaky hands
- Voice and head tremors
Symptoms tend to develop gradually and get worse with stress and fatigue.
Symptoms of Parkinson’s Disease: Tremors
Parkinson’s symptoms are clustering.
Symptoms Include:
- Resting tremors
- Muscle rigidity
- Slowness of movement
- Difficulty walking
- Balance issues
- Less facial expression
Difficulty with frequent tasks typically increases.
How Is the Diagnosis Done?
Doctors must first complete an extensive neurological assessment to mediate between medication and further interventions.
Neurological Examination
Using the following to assess:
- Severity of tremors
- Coordination and balance
- Muscle rigidity
- Tremors’ impacts on daily activity
- Response to changes in medication
MRI Brain Scan
MRI imaging excludes all other neurological disorders while complementing the treatment plan.
CT Skull Density Scan
This is mostly required when focusing on the treatment being offered via ultrasound.
Medical History and Health Assessment
Doctors also check on:
- Other disorders
- Recent medication
- Heart issues
- Diabetes
- If the treatment is appropriate
Treatment pathways differ, making accurate analysis vital.
Medication for Tremors
Therapy for tremor disorders is primarily through medication.
Common Goals of Medication
- Less movement when shaking
- More control of the hand
- Less discomfort while completing daily activities
Excellent control of tremors in the earliest stages is noted for many patients.
Advantages of Medication
Non-Invasive Approach
No incisions, surgeries, or procedures.
Easy to Start
Treatment is immediate upon diagnosis.
Helpful in Early Stages
Managing your medications properly is integral to obtaining symptom relief.
Limitations of Medication
Medications gradually become less effective for some individuals.
Common Challenges Include:
- Uncontrolled tremors
- Drowsiness
- Dizziness
- Quality of life complaints
Some individuals note fatigue, balance difficulties, and tolerance to higher doses of medications.
What is Focused Ultrasound Treatment?
Ultrasound that is focused and guided by an MR is a non-invasive way to alleviate one of the parts of the brain that is responsible for tremors by using ultrasound waves.
MRI allows intervention, to some extent, during the treatment to assess the condition of the patient while treatment is being administered, and eliminates the need for surgical intervention.
This treatment is primarily used for:
- Essential Tremor
- Parkinson’s tremors
- Tremor-dominant Parkinsonism
Advantages of Focused Ultrasound
Non-Surgical Treatment
Ultra-focused treatment can be made.
With the elimination of cuts, stitches, and implanted hardware.
Patients engage in active treatment and monitor symptoms with the alternative of shorter recovery times in evaluation.
Immediate Tremor Improvement
Improvement is evident during treatment for some.
Reduced Dependence on Medication
For certain, there is a required reduction in the number of medications taken.
Limitations of Focused Ultrasound
- Some patients are not suitable.
- The treatment is a function of skull density.
- The targeted symptoms are tremors.
- Monitoring the patient’s condition remains crucial after the treatment.
When Should You Consider Advanced Treatment?
The need for Advanced treatment is evident when tremors are the main cause of the decline of the patient’s quality of life.
Signs That Medication May Not Be Enough
Difficult Daily Activities
Patients may have difficulty with:
- Eating
- Speaking
- Writing
- Dressing
- Using Technology
Tremors May Not Be Managed
Tremors may have remained for more than one medicine, a higher dose, or multiple medicines.
Vestibular Medicine Side Effects
Drowsiness, dizziness, and confusion can affect daily activities and may affect function due to loss of balance.
Decreased Activities of Daily Living
Patients’ tremors worsen, and they are more dependent on family.
When these effects cause emotional distress and disrupt daily activities, general neurologists or movement disorder specialists may consider Focused Ultrasound as an advanced therapy.
Factors That Affect Treatment Strategies
Age and Health Status
Some elderly patients may prefer more conservative options.
Severity and Relentless Nature of Symptoms
Patients with more severe and resistant tremors may have more severe symptoms.
Patient Preference
Some patients prefer avoiding a long-term medication regimen, while others would prefer avoiding multiple procedures.
Medical Eligibility
A full and comprehensive neurological assessment and imaging are prerequisites for MRgFUS.
Concerns Focused Beam Ultrasound
Recovery usually occurs much more quickly than after surgical procedures and has much less downtime.
Patients frequently improve their balance or have difficulty giving.
Conclusion
The use of medication and conservative options is a first line for treating all cases of tremors. Focused ultrasound may be the answer for patients who have severe tremors and/or troublesome side effects from medication.
Each option obviously has pros and cons. The correct option will be different for everyone and will depend on how the symptoms affect quality and level of functioning. It will also depend on the medical condition and personal goals for improvement. Accurate diagnosis and thorough evaluation by an expert in the field of neurology will be the most important in any of these options and interventions.
Tremor patients with progressively worsening symptoms should reach out to a neurologist to discuss whether more advanced treatment options can increase functioning and improve quality of life.
Frequently Asked Questions
1. When should tremor patients consider Focused Ultrasound treatment?
When patients are experiencing tremors that do not respond to treatment with medications, their lives are substantially impacted.
2. Can Focused Ultrasound replace medication completely?
Retroactively, the focus of medication requirements could also be shifted to ultrasound therapy.
3. Is Focused Ultrasound suitable for all tremor patients?
Depends on a variety of factors, including diagnosis, skull density, symptom severity, and medical condition.
