What’s The Difference Between Parkinson’s And Essential Tremor

Tremors Yes Parkinsons Disease No

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

Essential tremor is often mistaken for Parkinsonâs disease, but the two conditions differ in several ways. Essential tremor is an action tremor, meaning that the involuntary shaking increases when you move and try to use your hands. In Parkinsonâs disease, tremors occur mainly at rest, and activity reduces the symptoms. Some people with essential tremor develop head nodding or shaking few people with Parkinsonâs do. Balance problems and rigidity of the arms and legs are common features of Parkinsonâs disease but not of essential tremor. One of the hallmarks of essential tremor, useful in diagnosing the disorder, is that alcohol can temporarily ease symptoms in Parkinsonâs, alcohol has little effect on the tremor.

Parkinsonâs disease is marked by a progressive loss of brain cells that produce dopamine, a chemical messenger that enables normal body movements. Essential tremor also appears to involve a disruption in the activity of motor pathways, but itâs uncertain whether there is any loss of brain cells. Postmortem examinations of brain tissue taken from people with essential tremor reveal various abnormalities in the cerebellum and brainstem, including the loss of Purkinje cells, which produce an important neurotransmitter, called GABA. But the samples donât all show the same changes, so the import of these findings is uncertain.

Clinical Situation #: Et Or Et+pd

Clinical summary

A 40-year-old woman with a family history of ET develops a kinetic tremor and, a few years later, a postural head tremor. Her tremor worsens considerably such that she has severe and debilitating tremor by the age of 65 years. At 70 years of age, she also develops a tremor at rest with no other features of parkinsonism.

This patient likely only has ET with isolated rest tremor, a feature that can develop in ET cases with longstanding and severe disease.

Misperception #: The Tremor Of Et Is Bilateral & Symmetric

Action tremor in patients with ET is usually, though not always, bilateral, and it is typically asymmetric . In a community-based study of 54 patients with ET, the use of clinical rating scales revealed on average a 1.32-fold sideside difference, and quantitative computerized tremor analysis revealed on average a 1.71-fold sideside difference in arm tremor severity . Unilateral arm tremor is less common, reportedly occurring in 2, 4.4 and 10% of ET cases, with values varying depending on the criteria used . One study evaluated unilateral arm tremor in 412 ET cases from 133 kindreds with presumed autosomal dominant ET . Inclusion criteria required unilateral kinetic or postural tremor for at least 5 years, without dystonic posturing or bradykinesia/rigidity . Only subjects with a first-degree relative with definite ET were included . Eighteen patients were identified as having isolated unilateral arm tremor without tremor affecting other body segments . Out of the 18 patients, 13 had a combination of postural and kinetic tremor and 5/18 had only unilateral postural tremor . Isolated unilateral postural tremor should raise the suspicion of PD, and the patient should be followed closely for the development of additional signs suggestive of PD.

Clinical pearl #3: Action tremor in ET is often but not necessarily bilateral. Small to moderate sideside differences are the rule rather than the exception.

Do Wrist Weights Help With Essential Tremors

Then they turn to treatment. Non-medical approaches to treating essential tremor include weighting the arms with wrist weights, and using weighted utensils or a weighted pen to reduce the tremor and improve function. Relaxation techniques and biofeedback can help if your tremors are worsened by anxiety.

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.

Are There Ways To Treat Essential Tremor Without Medications

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.

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.

Misperception #: Action Tremor = Et & Not Pd

Action tremor is the hallmark feature of ET and can be further subdivided into postural, kinetic and intention tremors. Yet just as rest tremor may occur in patients with ET, conversely, action tremor may be found in patients with PD. Indeed, it is not uncommon to encounter patients with PD who have various forms of action tremor. Below, we discuss postural, kinetic and intention tremors separately.

Clinical pearl #2: Although action tremor is the hallmark feature of ET, it is commonly found in patients with PD as well. When evaluating kinetic tremor in a particular patient, comparing it to other tremor types within that patient may help distinguish PD from ET. Thus, kinetic tremor is generally of greater amplitude than postural tremor in ET whereas the converse has been reported in PD. Intention tremor with limb dysmetria is more suggestive of ET than PD. Some of the clinical features of action tremor may similarly suggest one disorder or another. Thus, a postural tremor whose frequency is similar to the 4- to 6-Hz rest tremor of PD is suggestive of PD. A postural tremor with a significant latency is also more characteristic of PD.

Clinical Situation #: Et+pd

How to distinguish Parkinson’s disease from Essential Tremor – New Day Northwest

Clinical summary

A 45-year-old woman develops a bilateral action tremor than progressively worsens over the ensuing 15 years. Kinetic tremor is more severe than the postural tremor and she subsequently develops a postural head tremor. At 60 years of age, she develops a rest tremor in the right arm accompanied by bradykinesia .

The bilateral, progressive action tremor of long duration suggests ET and the subsequent development of a postural head tremor supports the diagnosis. The patient subsequently develops two parkinsonian signs, satisfying criteria for a clinical diagnosis of PD. The patient thus has a combination of ET+PD.

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.

What Is Essential Tremor

Essential tremor is a neurological disorder that causes involuntary, rhythmic shaking. While it can affect any part of the body, essential tremor often occurs within the hands. People with essential tremor have difficulty performing many simple tasks, like eating cereal, tying their shoes, or drinking from a glass.

Clinical Situation #: Pd Or Pd+et

Clinical summary

A 65-year-old man with rest tremor and rigidity in the right arm is diagnosed with PD. Five years later, he develops a postural tremor of his right arm, which occurs after a latency of 10 s and a frequency similar to his 4-Hz rest tremor.

A re-emergent tremor with similar frequency to the patients rest tremor is consistent with a diagnosis of PD. There are no additional features to suggest ET.

Rest tremor is a cardinal feature of PD, and resolves upon initiation of movement. When it is accompanied by bradykinesia and rigidity, PD is high in the differential diagnosis. The proportion of PD patients with rest tremor has been reported to be 90% in clinical series and 76100% in postmortem series . Patients with PD may also have tremor-predominant PD, in which rest tremor occurs in the relative absence of other signs of akinesia and rigidity.

Clinical pearl #1: While rest tremor may be seen in 2030% of patients with ET, it tends to occur in patients with more severe disease and disease of longer duration. In addition, it may differ qualitatively from the type of rest tremor that occurs in patients with PD.

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.

What Is The Difference Between Tremors And Parkinsons Disease

While the majority of Parkinsonâs patients experience tremors,not everyone who has tremors has Parkinsonâs. 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. Parkinsonâs disease is a neurological disorder that causes tremors,stiffness in limbs and loss of coordination.

The most significant difference between tremor associated withParkinsonâs disease and tremor associated with other conditions is thatParkinsonâs tremor is typically a âresting tremor,â meaning it ispresent when an individual is at rest and goes away when the individual isactive. Tremors in most other conditions are classified as âactiontremor,â meaning shaking increases when a person is active and decreaseswhen the person is at rest.

While Parkinsonâs 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.

Symptoms Of Parkinsons Disease And Essential Tremor

The differences between Parkinsons and an essential tremor include:

  • Tremors are mostly seen when the body is at rest in Parkinsons disease.
  • Tremors occur at a higher frequency and when trying to reach things in essential tremor.
  • Both start on one side of the body, commonly in the hands. Some Parkinson plus syndrome starts on both hands.
  • Essential tremors can be seen in other family members 50% of the time.
  • Tremors in head and voice are more common in essential tremor.
  • Other symptoms can be seen in Parkinsons patients including stiffness, balance issues, gait issues, and slowed movements.
  • Parkinsons patients often experience a change in handwriting which makes the letters very small, while essential tremor handwriting gets large and quivery.

There are also other causes for tremors, such as: medication induced tremors, vascular tremors, and metabolic associated tremors. The diagnosis is made based on a complete medical history and physical exam, sometimes with the help of lab and imaging tests, by a neurologist. It is important to write down the symptoms you are having and be as specific as possible so you can share the details with your doctor.

What Is Parkinsons Disease

Differences Between Essential Tremor and Parkinson’s Disease

Parkinsons disease is a progressive condition that causes trouble with movement. Its caused by the death of cells in a part of the brain called the substantia nigra. This part of your brain produces the neurotransmitter dopamine.

In some cases, specific genetic mutations are linked to the development of Parkinsons. But more often, it seems to appear randomly. Its thought that environmental factors such as exposure to pesticides, herbicides, or air pollution may contribute, but more evidence is needed to understand the potential link.

According to the , Parkinsons most commonly develops in people over the age of 60 and affects men about 50 percent more often than women.

Bedside Examination: Distinguishing Et From Pd

Although the aforementioned diagnostic criteria attempt to clearly delineate ET from PD, it is not uncommon for patients with ET to exhibit PD signs and, conversely, for patients with PD to exhibit ET signs. This overlapping of neurological signs is a source of diagnostic uncertainty. Clinicians should both be aware of this potential for overlap and look for the specific features that point to the correct diagnosis of ET or PD. Below, we address a number of common clinical misperceptions about these two diseases these misperceptions fuel the diagnostic confusion. In doing so, we will review the neurological findings classically associated with PD and ET, as well as the subtle findings on examination that help to further distinguish the two disorders.

What Causes Essential Tremor

Unlike Parkinsons disease, which rarely has a genetic link, essential tremor is often hereditary. Roughly half of people with essential tremor will inherit it from their family in whats called an autosomal dominant fashion, meaning if one parent has it, theres a 50% chance that each child will have it, says Weintraub. The other 50% of cases are sporadic, meaning they happen without there being a family history of the condition.

Other Differences Between Parkinsons Disease And Essential Tremor

Several other factors can be used to distinguish between essential tremor and tremors from Parkinsons disease.

Family History

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.

Other Symptoms

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 .
