Other Tremors And How It Differs
A Parkinsonian tremor has a few distinct characteristics, though it may be easy to confuse with other types of tremors depending on the other symptoms a person shows. Doctors will look for and rule out other types of tremors to confirm their diagnosis.
The National Institute of Neurological Disorders and Stroke notes that some common tremors include:
Causes: Parkinsons Vs Essential Tremor
The cause is largely unknown for both Parkinsons and essential tremor. However, there are theories about what may cause these conditions.
In regards to essential tremor, John Hopkins Medicine notes that there is a theory that the condition may be caused by miscommunication between the cerebellum and other parts of the brain. There is also believed to be a genetic predisposition for developing essential tremor. You may be 50% more likely to develop essential tremor if your parent has the condition.
It is also important to note that certain factors can also cause other types of tremors. For example, according to the National Institute of Neurological Disorders and Stroke, certain medications, thyroid overactivity, and toxins like lead and mercury can produce tremors that might be confused with this condition.
In regards to what causes Parkinsons disease, the direct cause as to why specific individuals develop Parkinsons is unknown. However, what happens within the body that causes Parkinsons symptoms to manifest, is the gradual loss of brain cells that are responsible for producing dopamine. When this happens, it can interfere with normal body movement, leading to patients to exhibit the common symptoms of Parkinsons.
Age Of Tremor Onset And Its Influence On The Cognitive Performance Of Et
When we stratified ET patients by age of tremor onset, 58 had their onset prior to age 65 years and 122 had an onset 65 years. The two groups differed in terms of their median current age . Their neuropsychological performance was similar in all tests, with only the one exception of the animal naming task . When we computed the adjusted T-scores by age and educational attainment, this difference was no longer significant .

What Can I Expect If I Have Essential Tremor
Essential tremor is usually progressive, meaning it gets worse over time. This is usually a slow process. The average rate that arm or hand tremors get worse is between 1.5% and 5% a year.
Essential tremor starts small and usually only affects your hands at first. Over time, usually many years, the tremors may spread to affect your arm and head. As the condition progresses, you may begin to struggle with certain activities and may need help to do them.
How long does essential tremor last, and can it go away?
Essential tremor is a permanent, life-long condition once it starts. Its not curable, and it doesnt go away on its own.
Whats the outlook for essential tremor?
In years past, the term benign, meaning harmless, was a standard part of its name, as in benign essential tremor. However, experts now recognize that while essential tremor isnt harmful directly, it can cause severe disruptions in your life.
People with more severe tremors struggle with activities such as cooking, using kitchen utensils, drinking from a cup, hygiene activities, grooming and dressing. Some people who have essential tremor eventually cant live independently and need to live with family or in an assisted living or skilled nursing facility setting.
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.

What Causes Essential Tremor
The cause of essential tremor is unknown. However, one theory suggests that your cerebellum and other parts of your brain are not communicating correctly. The cerebellum controls muscle coordination.
In most people, the condition seems to be passed down from a parent to a child. If your parent has ET, there is a 50% chance you or your children will inherit the gene responsible for the condition. Sometimes, ancillary testing such as brain imaging or genetic testing may help with the diagnosis.
Are There Surgical Options For Essential Tremor
Deep brain stimulation is a therapeutic option for those with severe disabling ET not already managed by medications. DBS is often described as a pacemaker for the brain. It works much like a pacemaker, sending electrical signals to the brain instead of the heart. It is primarily utilized for patients who have Parkinsons disease, dystonia, or essential tremor, who cant adequately control their disease with medication.
Thalamotomy, involving the destruction of tremor producing cells in the brain region called the thalamus, is another surgical option. Using a small temperature-controlled electrode, a permanent lesion is created in the thalamus that helps to stop tremor without disrupting sensory or motor control.
Talk to your doctor about surgical and non-surgical options that are right for you.

Data Abstraction And Analyses
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 .
Essential Tremor And How To Manage It
Essential tremor is less well known than Parkinson’s disease, but it’s far more common.
For many, the late actress Katherine Hepburn provided an indelible public image of essential tremor. Her quavering voice and trembling hands unmistakably betrayed the disorder.
Essential tremor affects about 5% of people over age 50. The intensity of the shaking from essential tremor can be mild to very significant. Also the tremor can vary in location, being most prominent in the hands, head or voice.
For people with essential tremor, holding a coffee cup, writing a note, buttoning a sweater, and applying makeup can all be challenging and sources of frustration or embarrassment. When essential tremor interferes with independent living or holding a job, it can be devastating. Fortunately, there are medications that help control the essential tremor symptoms, and ways to make the tasks of daily living easier.

What Are The Similarities Of Essential Tremor And Parkinsons Disease
The most significant similarity between essential tremor and Parkinsons disease is their characteristic symptom: the presence of tremors. Both conditions are movement disorders with tremor as the primary symptom.
In both essential tremor and Parkinsons disease, tremors are most common in the hands. With essential tremor, people may also experience head and voice tremors. In Parkinsons, however, tremors can also be in the jaw or tongue, but almost never involve a persons head or voice. In rare cases, essential tremor and Parkinsons can also affect someones legs.
Tremors in both Parkinsons disease and essential tremor both worsen during periods of high stress. Stressful situations can also result in more severe shaking or cause shaking in parts of the body that are not usually affected by tremors.
Both conditions and their symptoms can interfere with daily life, though the extent to which a person is affected may depend on the severity of their tremors. Larger, more grand tremors can make everyday tasks difficult and have a negative effect on a persons quality of life.
What Is The Difference Between Tremors And Parkinsons Disease
While the majority of Parkinsons patients experience tremors,not everyone who has tremors has Parkinsons. Tremors are also asymptom of other conditions, such as traumatic brain injury, stroke, certainmedicines, alcohol poisoning or anxiety.
Tremor is an unintentional, rhythmic musclecontraction that leads to shaking in one or more parts of thebody. Parkinsons disease is a neurological disorder that causes tremors,stiffness in limbs and loss of coordination.
The most significant difference between tremor associated withParkinsons disease and tremor associated with other conditions is thatParkinsons tremor is typically a resting tremor, meaning it ispresent when an individual is at rest and goes away when the individual isactive. Tremors in most other conditions are classified as actiontremor, meaning shaking increases when a person is active and decreaseswhen the person is at rest.
While Parkinsons is typically the most widely-known disease associatedwith tremor, a condition called essential tremor is more common, affectingapproximately 5% of people aged 65 and older.

How To Tell The Difference
While a primary care physician or internist may be the first doctor to see a patient with tremors, he or she is generally not the most qualified person to issue a diagnosis. Instead, a referral is made to a specialist called a neurologist who is trained and experienced in movement disorders. Since there are many things that can cause uncontrollable shakiness, the neurologists initial concern is ruling out a disease, especially PD. Since there are no lab tests that can confirm the diagnosis, the initial consultation usually consists of the following:
- Personal medical history, including any past or current medications

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.
Preliminary Estimates Of The Effects Of Deep Brain Stimulation On Gait Kinematics In Parkinson Disease And Essential Tremor
P. Testini, G. Skelton, D. Bernhard, S. Miocinovic, P. Aia, C. Buetefisch, L. Higginbotham, L. Scorr, S. Triche, J. Mckay, C. Esper
Objective: To determine the change in gait parameters following deep brain stimulation in Parkinson disease and essential tremor .
Background: DBS is an established treatment for akinesia, rigidity, and tremor in PD as well as for medication-refractory ET. However, its effects on gait are less understood .
Method: Database review from our kinematics laboratory between 2019 to 2022 identified 10 patients that had pre- and post-operative DBS quantitative gait kinematics measured via a 3D commercial motion analysis system. Pre- and post-operative assessments were performed in the medication off state for PD patients. Post-operative assessments were performed in the stimulation on state for all patients. Changes in gait outcomes from pre- to post- were expressed as effect sizes and categorized as small, medium, or large using established cutoff values. Due to sample size limitations and the preliminary nature of the study, no null hypothesis testing was performed.

Tremor In Other Conditions
While tremor is a common symptom of PD, 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 PD 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 PD.
What Is A Tremor
A tremor is a specific type of shaking that affects a particular area of the body. It is unintentional, meaning that the person experiencing the tremor is not doing anything on purpose to cause the shaking.
Tremors are also rhythmic in nature. That is, the shaking in a tremor is not completely random. The movements actually have their own rhythm, almost like the beat of a piece of music. A tremor does not have to be exactly on beat to qualify as such. But some sort of repetitive, cyclical nature to the shaking can distinguish the movements.
What Causes Essential Tremor And Is There Anything That Triggers It
Experts dont know exactly why essential tremor happens or if there are triggers that cause them to happen. However, theres evidence that it happens because of the changes in certain parts of your brain.
And while experts dont know exactly why essential tremor happens, they do know that this condition can run in families. About half of all essential tremor cases are inherited. This condition appears to be an autosomal dominant inherited condition. That means if one parent passes a mutated gene that causes essential tremor to you, theres about a 50% chance that youll inherit the condition.
Essential Tremor Vs Parkinsons Disease Explained
Tremors are one of the most characteristic symptoms of Parkinsons disease. They are so characteristic, in fact, that even those without the disease often associate the symptom with Parkinsons. But there are a number of medical conditions other than Parkinsons that could explain why a person may have tremors and bodily shakes.
One such condition is known as essential tremor. A person can be diagnosed with essential tremor but not Parkinsons. And you can have both. Because the movements associated with essential tremor are similar to the shaking that occurs with Parkinsons disease, it can be hard to tell the two apart.
Here is what you need to know about these two conditions so you can distinguish between them and understand your own diagnosis.

When Should I See My Healthcare Provider Or When Should I Seek Care
You should schedule to see your healthcare provider if you start to have unexplained shaking or tremors. Your healthcare provider will schedule regular follow-up visits to monitor your condition and adjust treatments as necessary. You should see them as recommended because these visits are important in helping you minimize this conditions disruptive effects.
You should also see your healthcare provider if you notice your symptoms are getting worse, to the point where theyre disrupting your activities and routine. You should see them, too, if you have side effects from medications or treatments that are similarly disruptive.
When should I go to the ER?
Essential tremor isnt a condition that directly threatens your health and well-being, so its unlikely that it will directly cause symptoms that need emergency medical care. However, you should talk to your doctor to find out if there are any possible reasons you might need emergency medical care. They can tell you what to watch for and what you need to do to take care of yourself if such problems occur.
A note from Cleveland Clinic
Essential tremor is a condition that causes parts of your body, most often your hands and arms, to shake. In its earlier stages, essential tremor is often minor and nothing more than an inconvenience or an annoyance. While essential tremor isnt a dangerous condition, it can still keep you from taking care of yourself and living independently if the tremors become more severe.

Other Differences Between Parkinsons Disease And Essential Tremor
Several other factors can be used to distinguish between essential tremor and tremors from Parkinsons disease.
It is more likely for those with essential tremor to have a family history of the disease than those with Parkinsons. More than half of people diagnosed with essential tremor have a family member with the same diagnosis or a related condition. In fact theres a term for that familial tremor. On the other hand, fewer than 10 percent of people diagnosed with Parkinsons disease have it in their family tree.
In people diagnosed with essential tremor, the tremor is the primary symptom that they demonstrate. Parkinsons disease involves its unique tremors, but it is also characterized by other symptoms. Those others include slow movements and general slowness , stiff body motions and a stiff body overall, and balance or coordination problems.
Response to Alcohol
When people diagnosed with Parkinsons disease consume alcohol, they usually will not see a change in their tremors or other symptoms. Those diagnosed with essential tremor, however, often experience a temporary reduction in their tremors after drinking alcohol .
