What Is An Essential Tremor Parkinson

Data Abstraction And Analyses

What is the difference between Essential tremor and Parkinson Disease tremor?

The retrospective clinical record reviewer used an electronic data abstraction form designed for the study . The neurologist reviewed every fifth record to ensure high quality data abstraction. Abstracted items were: age at most recent assessment, gender, use of medication at any point to treat ET, first-degree relative with ET or PD, age of reported onset of ET, age at time of initial sign of PD, age at PD diagnosis, predominant side of action tremor ET , initial PD sign based on neurological examination, and predominant side of each cardinal sign of PD based on neurological examination. In some analyses, we calculated odds ratios with 95% confidence intervals .

The Difference In The Prevalence

Essential tremor is more common than Parkinsons tremor. There are approx 41 million people worldwide are living with this condition. The current estimate shows that 4 out of 100 individuals over the age of 40 are affected by essential tremor.

The number of people suffering from Parkinsons disease is estimated to be 10 million. The statistic shows that around 4 percent of people with Parkinsons are diagnosed before the age of 50.

How Is Essential Tremor Treated And Is There A Cure

Theres 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 arent enough to help your tremors.

  • Medication: The most common medications, taken either on their own or in combination, to treat essential tremor are beta-blockers like propranolol and anti-seizure drugs like primidone.
  • Adaptive devices: Many devices have been developed to improve tremor control, such as weighted items, tremor-canceling devices, vibration devices and peripheral nerve stimulation.
  • Botulinum toxin: This involves injection into the tremoring muscles to temporarily weaken the muscles and lessen tremor severity.
  • Deep brain stimulation: This is a surgery to implant a device that delivers electrical impulses to a specific part of your brain. The electrical impulses interrupt the signals that cause essential tremor muscle movements. This can improve tremors on both sides of your body.
  • Focused ultrasound: This procedure uses ultra-high-frequency sound waves focused onto a single point in your brain involved in the production of tremor, destroying the targeted tissue. This destruction can greatly reduce the severity of the tremor and improve hand steadiness. This can improve tremors on only one side of your body.

What Causes Essential Tremors

It is generally accepted that tremor is caused when problems arise in the thalamus, which is the structure of the brain that is responsible for coordinating and controlling muscle activity. However, at this time, researchers and medical professionals are not exactly certain what causes essential tremor.

Researchers are currently analyzing changes in specific chromosomes that have been linked to the development of essential tremor, but there have been no confirmed genetic connections as of yet.

In patients with a family history of ET, the specific manner in which essential tremor is inherited can vary. Most of the time, ET is inherited in an autosomal dominant pattern, which means that one altered copy of a gene can cause essential tremor. However, this inheritance pattern is not found in other families with ET, making it an unclear and unconfirmed connection to family history and genetics.

Parkinsons Disease Vs Essential Tremor Early Symptoms How They Differ

Are Intention Tremors Common In Parkinson

As many as one million Americans currently live with Parkinsons disease and approximately 60,000 Americans are diagnosed each year. Around the world, more than 10 million people worldwide are living with the disease, according to the Parkinsons Disease Foundation.

A new study published in the journal Brain has shed new light on the genetics behind essential tremor, which is frequently misdiagnosed as Parkinsons disease. Understanding the differences between both diseases is key to reducing the prevalence of medical mistakes. Heres everything you need to know about both diseases.

Which Body Parts Do Parkinsons Tremors Affect

There are five main places youâll have Parkinsonâs tremors:

1. Hands. Parkinsonâs disease tremors often start in the fingers or hands with whatâs called a pill-rolling motion. Imagine holding a pill between your thumb and index finger and rolling it back and forth.

2. Foot. A Parkinsonâs foot tremor is more likely to happen while youâre sitting or lying down with your feet at rest. If the tremor moves into your thigh muscles. It could look like your whole leg is shaking.

Foot tremors disappear when you stand or walk because those are active movements. A foot or leg tremor while youâre standing may be another condition.

3. Jaw. This is common in people with Parkinsonâs. It may look like youâre shivering. It can become bothersome if the tremor makes your teeth chatter. If you wear dentures, it could make them shift or fall out.

Chewing eases the tremor, so gum might help.

4. Tongue. Itâs rare, but a tongue tremor can cause your entire head to shake.

5. Internal. Some people with Parkinsonâs say they can feel a shaking sensation in their chest or abdomen. But canât be seen from the outside.

Predominant Side Of Et Tremor And Predominant Side Of Pd Signs

The side of greatest initial ET action tremor severity generally matched that side of greatest severity of each PD sign : diminished arm swing , limb bradykinesia , rigidity , and rest tremor . Results were similar when the side of greatest initial ET action tremor severity was determined by neurological examination as opposed to by patient history.

Diagnosing Parkinsons Vs Essential Tremor

The difference between essential tremor and Parkinsons can be so slight that it can be difficult for doctors to diagnose these conditions correctly. In fact, they are often mistaken for one another, which can be frustrating for physicians and patients alike. Specialty physicians that diagnose and treat these conditions are Movement Disorder Neurologists.

While there are no official tests for either condition, there are several diagnostic techniques that physicians employ to attempt properly diagnose essential tremor vs. Parkinsons, including:

  • Physical examination: During a physical examination, a physician evaluates the patients motor skills to help in their determination of whether they suffer from essential tremor vs. Parkinsons.
  • DaTscan: During a DaTscan, a radioactive tracer is injected, which makes its way into the brain, where it attaches to dopamine transporters. Special imaging scans are then conducted to see whether the dopamine system is healthy. If it is irregular, it may help diagnose your condition as Parkinsons.
  • Handwriting sample evaluation: A doctor may be able to differentiate Parkinsons vs. essential tremor using a handwriting sample because those with Parkinsons typically exhibit exceptionally small handwriting, whereas those with ET exhibit larger, shaky handwriting.

Resting Tremor Vs Action Tremor

Tremor Disorder or Parkinson’s?

Tremor is categorized into two main classifications: resting tremor and action tremor.

Resting tremor refers to shaking that occurs when a persons muscles are relaxed or at rest. For example, a person may experience a resting tremor in their hands when the persons hands are resting in their lap. Resting tremor only affects a persons hands or fingers .

Action tremor includes tremor that accompanies a persons voluntary movement, such as walking or moving the arms. Most tremors are considered to be action tremors and fall under various subcategories:

  • Postural tremor: occurs when a person attempts to maintain a position against the force of gravity, such as holding their arms outstretched.
  • Kinetic tremor: accompanies voluntary movement like blinking or moving hands.
  • Intention tremor: occurs when moving toward a target and worsens as a person nears their target, like touching the face with a hand or reaching for an object.
  • Task-specific tremor: manifests itself when an individual tries to perform a task involving skill or precision, such as handwriting or speaking.
  • Isometric tremor: accompanies voluntary muscle contractions that are not associated with movement, as when holding a dumbbell or other heavy object.

  • Leo Nguyen

The International Essential Tremor Foundation estimates that there are over 10 million people with essential tremor throughout the world . Essential tremor is known as a quiet disorder because it doesnt make headlines like numerous other conditions. Still, essential tremor impacts a persons quality of life by making it difficult to perform even the most simple tasks of daily life.

Research shows that 3 in 1,000 people deal with essential tremor throughout the world . People with essential tremor deal with shaky hands and often, though not always, develop neurological signs like an unsteady gait .

Contrary to popular belief, essential tremor is not exclusive to the elderly. In fact, the IETF notes that there is a 4% to 5% chance of essential tremor occurring in those between the age of 40 to 60 years old. In the elderly, IETF highlights that the incidence rate for essential tremor is between 6.3% and 9% in those over 60 years old.

How Is Parkinsons Tremor Diagnosed

There are no specific tests or procedures to diagnose Parkinsons disease.

Diagnosis typically relies on a doctors observation of your symptoms and medical history. A diagnosis of Parkinsons disease is typically confirmed with:

  • the presence of two or three primary symptoms of the disease
  • other diseases can be excluded as the cause of symptoms
  • no history of injury or medication use that could lead to Parkinsonian symptoms
  • some improvement in response to medications used to treat Parkinsons

Some imaging techniques, such as PET scans, can help confirm a diagnosis. But these arent used to make one.

If your doctor wants to pinpoint the type of tremor youre having before making a Parkinsons diagnosis, some testing methods for

Treatments are usually adjusted to achieve the best relief for each persons symptoms and medical history.

Some patients may benefit from the Liftware device, which helps patients to eat with less spillage. This device comes with a stabilizing handle and a utensil attachment and works by stabilizing the utensil so that less food is spilled. Stress management and physical therapy are helpful for those with mild to moderate ET, but are typically used in combination with medications and/or surgery. For those with symptoms not controlled satisfactorily by medications, deep brain stimulation or thalamotomy can be helpful in improving symptoms and may even help to reduce the amount of medications needed to improve symptoms. Your neurologist will be able to help you determine options that are right for you.

Essential Vs Parkinsons Disease: Similar But Different

The primary symptom of essential tremor is shaking, often in the hands, which means many misunderstand the signs of essential tremor vs. Parkinsons disease.

Those dealing with essential tremor often withdraw from public activities due to the embarrassment resulting from tremor-induced messiness and shaking.

This seclusion, combined with the relatively small amount of media coverage regarding essential tremor, means that individuals and physicians often misdiagnose essential tremor as being Parkinsons disease. Research shows that the misdiagnosis rate in essential tremor studies ranged between 37% and 50% .

When Does The Shaking Occur

The most significant difference between essential tremor and Parkinsons disease has to do with when a persons tremorous movements occur. In someone with essential tremor, their shaking occurs when part of their body is active. In someone with Parkinsons disease, their tremor occurs in parts of their body when those parts were otherwise at rest.

Imagine watching someone with a tremor while they are relaxing on the porch. In a person diagnosed with essential tremor, you may not know they have a tremor until they try to move the affected body part. For example, when they reach for their glass on the table, their hand may shake.

In a person with a tremor from Parkinsons disease, you will see the tremor while they are at rest. Their hand may shake while it is on their lap or resting on the arm of their chair. When they reach for their glass, though, the tremor will stop until their hand is at rest again.

Who Is Affected By Tremor

About 70% of people with Parkinsons experience a tremor at some point in the disease. Tremor appears to be slightly less common in younger people with PD, though it is still one of the most troublesome symptoms. People with resting tremor usually have a more slowly progressing course of illness than people without tremor.

How Can You Tell The Difference Between Essential Tremor And Parkinsons Disease

Essential tremor is a neurological disorder that causes tremors, generally of both hands, but also the head and voice. It is often confused with Parkinsons disease, but the tremor in essential tremor is an action tremor, which means that the tremor is most noticeable when the limb is in use or moving and improves when the limb is at rest. This is opposite of the tremor seen in Parkinsons disease, which is most noticeable when the limbs are relaxed and at rest, and lessens when the affected limb is in use.

What Causes Parkinsons Disease

The exact cause behind the loss of neurons in this movement disorder is unknown. However, ongoing research has shown that several factors may play a role in the development of Parkinsons disease, including genetic factors and environmental triggers.

Regarding genetic factors, the last two decades of Parkinsons research have revealed about 30 genetic loci that may be linked to the pathogenesis of Parkinsons disease .

In addition to genes, environmental factors may also play a role in the onset of Parkinsons disease. For example, several studies suggest that Parkinsons may develop with prolonged occupational exposure to chemicals like pesticides and heavy metals or electrical roles .

What Are The Symptoms Of Parkinsons Disease

Since Parkinsons disease causes the brain to lose control of movement, the most obvious symptom of the disease is tremor. In Parkinsons disease, the tremor starts involuntarily in the arm even when the person is not moving or not doing anything. This type of tremor is called rest tremor. Parkinsons disease slows and stiffens muscle movements. As the disease progresses, it can also affect a persons ability to balance, especially while walking.

There are 5 stages of Parkinsons disease:

  • Uncontrollable shaking and involuntary tremor
  • Slowed movement, known as bradykinesia
  • Balance issues and decreased reflexes
  • Stiffness in the limbs
  • Possible dementia, confusion, and hallucinations

Nearly 50 percent of those with stages 4 and 5 of Parkinsons disease experience confusion, hallucinations, and delusions, according to a 2016 study.
