Essential tremor treatment
There’s no cure for essential tremor, but there are ways to treat it. The main treatment options are medications, assistive devices, botulinum toxin, deep brain stimulation and focused ultrasound. Your healthcare provider may recommend deep brain stimulation or focused ultrasound if other treatments aren’t enough to help your tremors.
Essential tremor is a movement disorder that causes uncontrollable shaking of your hands, arms and other body parts.

Medication
What is the treatment for essential tremor? Essential tremor cannot be cured. Treatment may reduce the severity of the tremor. There are various treatments that are used.
Medication There are two medicines used initially for essential tremor - propranolol and primidone. These medicines have been shown to ease the tremor in up to 8 in 10 affected people.
Propranolol - this is a medicine that is usually used in heart disease. It is in a class of medicines called beta-blockers. It has also been shown to be effective in essential tremor. This medicine should be used with care if you have a heart conduction problem or a lung disease such as asthma. The most common side effects with propranolol are dizziness, tiredness, and nausea (feeling sick).
Primidone (Mysoline), - this is a medicine that is primarily used for epilepsy, but it also works very well in essential tremor. The most common side-effects are sleepiness, dizziness and nausea. These may improve if you continue to take this medicine.
OnabotulinumtoxinA (Botox) injections. Botox injections might be useful in treating some types of tremors, especially head and voice tremors. Botox injections can improve tremors for up to three months at a time.
However, if Botox is used to treat hand tremors, it can cause weakness in your fingers. If it's used to treat voice tremors, it can cause a hoarse voice and difficulty swallowing.
When the diagnosis of essential tremor is made, you may be offered one of these medicines. A low dose is usually started at first, and gradually increased until your tremor is eased. If you reach the maximum dose without a satisfactory improvement, then the other medicine can be tried. If that also doesn't work, you can try them together. Other medicines can be tried if these two are not effective. A wide range of medicines have been shown to have some effect on reducing the severity of the tremor.

Learn more about Essential Tremor
Essential Tremor is caused by overactive cells in the area of the brain called the thalamus. The thalamus is about the size of a walnut and within the brain there are two of them. If there are overactive cells in the right thalamus, the person will have signs of tremor on the left side and vice versa. Some patients suffer from tremor on both sides.
Diagnosing Essential Tremor involves reviewing your medical history, family history and symptoms and conducting a physical examination.
Doctors don’t understand the true cause of essential tremor, but it’s thought that the unusual electrical brain activity that causes it is processed through the thalamus. The thalamus is a structure deep in the brain that coordinates and controls muscle activity.

Surgery
If medicine treatment is not effective, and the tremor is severe, then a surgical procedure may be an option. There are three surgical procedures that may be considered - thalamic deep brain stimulation (DBS) plus there are alternative less invasive treatment options for Essential Tremor such as the Focused Ultrasound Treatment.
They involve the thalamus. This is a deep part of the brain that organizes messages travelling between the body and brain.
Thalamic deep brain stimulation- this procedure involves placing an electrode (fine wire) into the thalamus on one or both sides of the brain. The electrode is connected to a device called a stimulator. The electrode and stimulator stay in the body. (The stimulator is placed under the skin at the top of the chest.) The simulator sends electrical impulses down the electrode to the thalamus. It is not known exactly why this device works. It seems to interrupt or block the nerve signals coming through the thalamus that cause the tremor. If you have this procedure, you will need to have regular reviews to make sure that the stimulator setting is correct. This aims to minimize side-effects and maximize benefit. It may produce a good response in up to 9 out of 10 affected people. Again, there is a small risk that the procedure may cause a bleed into the brain. Side effects include loss of sensation, speech problems, and weakness. These usually resolve when the stimulator settings are adjusted.
Focused Ultrasound
Focused Ultrasound Treatment for Essential Tremor Now Covered by Medicare
Focused ultrasound is a non-invasive surgical procedure for Essential Tremor that can’t be controlled with medication. For some people, focused ultrasound may be an alternative to deep brain stimulation surgery.
What is focus in ultrasound?
How Does Focused Ultrasound Work? Similar to how a magnifying glass can focus beams of light on a single point, focused ultrasound uses an acoustic lens to concentrate multiple sound waves on a point in the body. Your providers use magnetic resonance imaging (MRI) to guide the waves and target diseased tissue.
Focused ultrasound is an early-stage, non-invasive therapeutic technology with the potential to transform the treatment of many medical disorders by using ultrasonic energy to target tissue deep in the body without incisions or radiation.
Focused ultrasound treatment for essential tremor has been approved by the Food and Drug Administration (FDA) in July 2016.Medicare approved the treatment in all US states as of July 12, 2020.The FDA approved staged bilateral treatment for essential tremor on December 20, 2022. Treatments are approved for the second side at least 9 months after the initial treatment.
Focused ultrasound is the marriage of two innovative technologies:
· focused ultrasound—which provides the energy to treat tissue deep in the body precisely and noninvasively, and
· magnetic resonance or ultrasound imaging—which is used to identify and target the tissue to be treated, guide and control the treatment in real time, and confirm the effectiveness of the treatment.
Neuravive/Focused Ultrasound
Similar to Gamma Knife’s approach, Neuravive aims to target and destroy the brain cells that are causing the patient to experience a tremor. However, Neuravive uses MR-guided focused ultrasound to treat the cells instead of ionized radiation. This technique has already seen success in treatment for uterine fibroids, prostate cancer, and other conditions. Patients often do not have to wait for results and generally enjoy a decreased tremor immediately following the procedure. Neuravive’s results are also not reversible or adjustable due to brain lesioning.
While patients have experienced positive results from Gamma Knife and Neuravive, results may vary from case to case.
This treatment approach requires no surgery or general anesthesia and results in minimal downtime. The procedure is performed as outpatient and does not require a hospital stay.
Difference in non-invasive procedures
MINIMAL HOSPITALIZATION and short recovery time
SHARP, ACCURATE Lesions as small as 2mm, no penetrating trajectories, no implanted hardware, no ionizing radiation, less risk of infection.
immediate results
Gamma Knife
The Gamma Knife procedure Is a non-surgical treatment using highly focused radiation to kill the cells causing the tremor. Overactive cells in this area can cause hand tremors in patients, and the ionizing radiation used during the procedure destroys the affected area without harming the surrounding, healthy tissue. Patients who opt for Gamma Knife generally see results within three to six months after the procedure, and they also experience lower complication rates in comparison to conventional surgery options. Because Gamma Knife destroys the affected cells, the results are not reversible or adjustable.
The result is an immediate and significant reduction of tremor for patients.

The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The main function of the thalamus is to relay motor and sensory signals to the cerebral cortex. It also regulates sleep, alertness and wakefulness.
Alternatives
Adaptive devices.
These are external devices that can help change or control how severe your tremors are. They may help anyone with ET, but people who have disabling tremors are generally not considered good candidates. The devices include neuromodulation devices that you wear and control yourself, and tremor cancellation devices that control hand tremors, allowing you to eat or write.

However, if Botox is used to treat hand tremors, it can cause weakness in your fingers. If it's used to treat voice tremors, it can cause a hoarse voice and difficulty swallowing.
There is some evidence that Botox injections are helpful in reducing certain tremors. Unfortunately, a Botox injection into the arm also produces weakness of the arm. This is usually not tolerated. It is mainly useful when essential tremor affects the head and neck.

What are Stem Cells?
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle or bone. No other cell in the body has the natural ability to generate new cell types.
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.

Alcohol - Many people find that alcohol is helpful in reducing their tremor. It needs to be used with caution to avoid developing an alcohol problem. It is not advisable to drink more than the normal recommended amount of alcohol. That is: men should drink no more than 21 units of alcohol per week, no more than four units in any one day, and have at least two alcohol-free days a week. Women should drink no more than 14 units of alcohol per week, no more than three units in any one day, and have at least two alcohol-free days a week. Pregnant women, and women trying to become pregnant, should not drink alcohol at all. One unit is in about half a pint of normal strength beer, or two thirds of a small glass of wine, or one small pub measure of spirits.
Research Study & Clinical Trials
Scientists at the National Institute of Neurological Disorders and Stroke are evaluating the effectiveness of 1-octanol, a substance similar to alcohol but less intoxicating, for treating essential tremor. Results of two previous NIH studies have shown this agent to be promising as a potential new treatment.
Scientists are also studying the effectiveness of botulinum toxin as a treatment for a variety of involuntary movement disorders, including essential tremor of the hand.
Avoid caffeine. Caffeine and other stimulants can increase tremors
Stress and anxiety Stress and anxiety tend to make tremors worse, and being relaxed may improve tremors.
What is the outlook? Essential tremor is a progressive disease. This means that it tends to gets worse over time. There needs to be more research on the cause to find more medicines that work for ET and to find a cure.

How is essential tremor diagnosed? There is no test to diagnose essential tremor. Your doctor can usually diagnose essential tremor based on your explanation of the tremor and an examination. It is important for the doctor to make sure that there are no other conditions present that are causing tremor. In some cases, this may mean that you need to have some tests to rule out other conditions. For example, blood tests or a brain scan. You may also be referred to a movement disorder doctor (a doctor with a special interest and expertise in the brain and nerves).
While the diagnosis of ET remains a visual one, certain brain scans Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) may be helpful in eliminating any other conditions which also produce tremor as a symptom. For example growths such as tumors or damage to the brain can be seen on certain brain scans. Blood samples may also be taken to rule out thyroid or copper metabolism problems, both of which can cause tremor. DATScan a diagnostic test can distinguish between ET and tremor of Parkinson's disease.
Other conditions that can cause tremor and need to be ruled out include a side effect from some prescribed medicines, anxiety, caffeine, some poisons, kidney, liver disease, thyroid disease, Parkinson's disease and other movement disorders.
Adaptive devices. These are external devices that can help change or control how severe your tremors are. They may help anyone with ET, but people who have disabling tremors are generally not considered good candidates.
