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.

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.

Tremor In Other Conditions
While tremor is a common symptom of Parkinsons, it can also be a symptom of other conditions, most notably essential tremor. The main difference between Parkinsons tremor and most other types of tremor is that in Parkinsons resting tremor is most common. Other conditions are usually characterized by action tremor, which tends to lessen at rest and increase when youre doing something, like trying to make a phone call or take a drink.
Tremors of the head and voice are also common in essential tremor but rare in Parkinsons.

Parkinsons disease is one of the most common and well-known neurodegenerative disorders in the world. Worldwide, estimates suggest that over 10 million people currently live with Parkinsons disease. In America alone, there are about 60,000 new Parkinsons diagnoses every year.
One of the main and most characteristic symptoms of Parkinsons disease is a tremor or involuntary shaking. However, Parkinsons disease is by no means the only condition that causes a tremor. Essential tremors are also noted by shaking. Learn more about the difference between essential tremor and Parkinsons disease below.

Parkinsons Disease Natural Treatment & Remedies In 5 Steps
Parkinsons disease is a degenerative illness of the nervous system that results in loss of intentional movement and impaired motor functioning. Parkinsons disease symptoms affects smooth, natural movements of the body, and can make it hard to perform everyday tasks like speaking properly, walking, swallowing and sleeping.
With Parkinsons, the area of the brain that controls muscular movements receives less dopamine than usual. Dopamine is an important chemical necessary for not only coordinating proper body movements, but also things like learning, increasing motivation and regulating moods. This is one reason why depression and other mood changes often affect those with Parkinsons.
What causes Parkinsons, and is it curable? There is no specific known cause, but some aggravating factors include exposure to certain chemicals and toxic water, plus inflammation of the brain. While there is no cure for Parkinsons , there are medications available to boost dopamine in the brain and help manage symptoms.
A 2016 study by researchers at the University of Saskatchewan also found a possible way to stop the progression of Parkinsons. Researchers created caffeine-based chemical compounds which also contained nicotine, metformin and aminoindan that prevented the misfolding of alpha-synuclein, a protein necessary for dopamine regulation.
Do You Qualify For A Paraquat Lawsuit
One of the criteria for joining the paraquat litigation is that you should have a Parkinsons disease diagnosis and a history of occupational exposure to paraquat. This does not mean, however, that only pesticide applicators may be eligible to file a claim.
Recent studies have actually revealed that the negative effects of exposure to the weed killer paraquat are not only limited to pesticide applicators. In fact, even residents living within 500 meters of a field where paraquat is being sprayed can also suffer the repercussions of being exposed to the weed killer.
Other studies have also revealed that the harmful effects of paraquat dichloride exposure can affect:
- People with known exposure to farm animals
- People who consume contaminated well water
- Individuals living in rural areas
Due to its high levels of toxicity, hundreds of paraquat herbicide lawsuits have been filed in federal and state courts across the country. In June 2021, all federally filed paraquat cases were consolidated into the U.S. District Court for the Southern District of Illinois.
Paraquat toxic exposure lawsuits are being filed everyday. If you believe you have a claim against the makers of paraquat, you can contact us today and explore your legal options with us.

Essential Tremor Is Not Parkinsons Disease
Essential tremor and Parkinsons disease are different conditions. Essential tremor is characterised by shaking when movement starts, which can continue or worsen during movement. The symptoms of Parkinsons disease include:
- involuntary tremor when you are not moving
- muscle stiffness
- slowness of movement
Parkinsons disease is caused by a lack of supply of the brain chemical dopamine, which is necessary for smooth and controlled muscular movement.
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.

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.
What Is The Difference Between Essential Tremor Andparkinson’s
The exact cause of essential tremor is unknown while Parkinson’sdisease is better understood.
In Parkinson’s disease, neurons located in the part of the brain thatcontrols movement become impaired or die. These neurons usually produce achemical called dopamine which enables regular body movements. When the neuronscan’t produce necessary levels of dopamine, tremors can occur, along withrigidity of limbs and decreased coordination.

Distinguishing Essential Tremor And Parkinsons Disease
While most people are familiar with Parkinsons Disease , Essential Tremor is much more common1.
If you are experiencing shaking of your hands, a neurologist specializing in movement disorders can perform testing to diagnose your condition. This may include holding your arms straight out in front of your body, touching your finger to your nose, and drawing spirals on a piece of paper. Additional testing or imaging scans may also be required as part of the diagnosis.
While only a qualified physician can provide a diagnosis, there are several key symptoms that differentiate Essential Tremor from other conditions such as Parkinsons Disease.
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% .

- Muscle and body rigidity
- Trembling hands, legs, and body
- Poor posture or postural instability
- Bradykinesia, which is the slowness of movement
- Pausing or freezing during walking
- Digestive issues
- Urinary problems, especially when it comes to controlling urination
- Speaking and carrying out complex conversations
- Trouble eating
- Changes in tone and cadence of voice
- Skin issues
These are just some of the many problems that indicate the onset of Parkinsons disease. If you experience or see a loved one experience any of these issues, contact a professional neurologist immediately. They will provide advice and recommend effective ways to manage the symptoms.

What Is Essential Tremor Disorder
Essential tremor disorder is a brain condition that causes rhythmic shaking in certain parts of the body. The head and trunk may also be affected, but hand shaking is predominantly involved.
This involountary shaking or trembling motion is called a tremor. Essential tremor is not exactly a serious condition, but it can gradually worsen over time and can also be easily confused with Parkinsons disease.
According to statistics, up to 7 million American struggle with essential tremor. Although its exact cause is still not fully understood, experts point to genetic vulnerabilities as its primary risk factor. People with this brain disorder may display an unsteady stance when walking that results from a lack of coordination while performing voluntary movements.
Moreover, at least half of people diagnosed with essential tremor are also affected by psychological disorders such as anxiety and depression. This can further affect a patients daily physical and psychological functioning.
How Might Music Therapy Help
Its been suggested that music can improve movement and speech and help people to relax or talk about their feelings or ideas.
Some people with Parkinsons find that listening to strong rhythmic music can improve their walking, prevent hesitations and overcome freezing episodes.
In general, research indicates that music seems to help people with conditions such as Parkinsons improve their emotional sense of wellbeing.

How Does Essential Tremor Develop
Essential tremor symptoms often first appear in a person’s 40s, when delicate movements such as threading a needle become difficult. But it’s usually not until people reach their 50s or 60s that the tremor becomes troublesome for example, making it difficult to use a fork, drink from a cup, or write a letter. Essential tremor progresses slowly. Though essential tremor may eventually affect the voice and head, many people find that their symptoms don’t progress beyond mild hand and arm tremor. Tremors are usually absent during sleep.
We don’t know the precise cause of essential tremor. Some experts believe that the problem lies in the cerebellum or its connections with the brainstem, which lies at the base of the brain. Essential tremor is a heritable condition. If you have essential tremor, your children will have a 50% chance of developing it as well.
What You Need To Know
- Essential tremor disorder is a neurological condition that causes your hands to shake rhythmically. The head, trunk and voice might also be involved, but hand shaking is most prominent. The cause is not known, but it is often passed down from a parent to a child.
- Essential tremor is sometimes confused with other types of tremor, so getting the right diagnosis is important.
- Tremors tend to be worse during movement than when at rest. The tremors can be disabling and can slowly worsen over time.
- Some things might make tremors worse, and avoiding them may be helpful. Medicines can also help control or limit tremors in some people. Severe tremors can sometimes be treated with surgery.

Service Connection For Essential Tremors
There are a few ways to establish service connection for essential tremors. These include direct Service Connection, secondary service connection, and service connection via aggravation.
Direct service connection means that there is a specific connection between your current disability and your time in service. VA must be able to directly link the two. In order to do this, youll have to show the following three:
For example, if you develop tremors after being exposed to a neurotoxin while on duty, you likely would have direct service connection.
Resting Tremor Vs Action Tremor
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.

What To Do If You Were Misdiagnosed With Essential Tremor
If you or your loved one were recently exposed to the paraquat herbicide and are starting to notice symptoms of Parkinsons disease, you should talk to a healthcare provider first and foremost.
And if you believe you may have received a misdiagnosis, its important to seek for a second or third opinion to get an accurate diagnosis of your condition.
Once it has been determined that you suffer from PD and you suspect it may be due to prolonged exposure to paraquat, you should immediately consult a paraquat attorney who can evaluate your case and determine if you have a case against the manufacturers of the toxic chemical.
