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.
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 .
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:
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.

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.

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.
Is Head Tremor The Same As Essential Tremor
Head tremor is often described as an oscillation of the head, causing it to move side to side or up and down. The tremor can be rhythmic like a pendulum or irregular and more pronounced. While head tremors can be one of many types of tremors experienced by those with essential tremor, they are also seen in patients with dystonia.

How Is Tremor Diagnosed
Doctors often diagnose tremors through physical and neurological examinations and a medical history review. During the physical evaluation, a doctor will assess the tremor to see if it occurs when your muscles are at rest or in action, where they are located on your body, if they occur on one or both sides, and their frequency and amplitude. They will also assess other neurological functions such as walking, balance, speech, muscle tone, and mobility.
What Can I Expect If I Have This Condition
Parkinsons disease is a degenerative condition, meaning the effects on your brain get worse over time. However, this condition usually takes time to get worse. Most people have a normal life span with this condition.
You’ll need little to no help in the earlier stages and can keep living independently. As the effects worsen, youll need medication to limit how the symptoms affect you. Most medications, especially levodopa, are moderately or even very effective once your provider finds the minimum dose you need to treat your symptoms.
Most of the effects and symptoms are manageable with treatment, but the treatments become less effective and more complicated over time. Living independently will also become more and more difficult as the disease worsens.
How long does Parkinsons disease last?
Parkinsons disease isnt curable, which means its a permanent, life-long condition.
Whats the outlook for Parkinsons disease?
Parkinson’s disease isn’t fatal, but the symptoms and effects are often contributing factors to death. The average life expectancy for Parkinson’s disease in 1967 was a little under 10 years. Since then, the average life expectancy has increased by about 55%, rising to more than 14.5 years. That, combined with the fact that Parkinson’s diagnosis is much more likely after age 60, means this condition doesn’t often affect your life expectancy by more than a few years .

What Are The Early Warning Signs Of Parkinson’s Disease
Parkinsons warning signs can be motor symptoms like slow movements, tremors or stiffness. However, they can also be non-motor symptoms. Many of the possible non-motor symptoms can appear years or even decades ahead of motor symptoms. However, non-motor symptoms can also be vague, making it difficult to connect them to Parkinson’s disease.
Non-motor symptoms that might be early warning signs include:
- Sleep problems such as periodic limb movement disorder , rapid eye movement behavior disorder and restless legs syndrome.

What Are The Symptoms Of Tremor
Symptoms of tremor may include:
- a rhythmic shaking in the hands, arms, head, legs, or torso
- difficulty writing or drawing
- problems holding and controlling utensils, such as a spoon.
Some tremor may be triggered by or become worse during times of stress or strong emotion, when an individual is physically exhausted, or when a person is in certain postures or makes certain movements.
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.

Signs & Symptoms: Is It Essential Tremor Or Parkinsons
In order to start managing your condition and receive the treatment you need, you should be aware of the most common signs and symptoms as well as the key differences between essential tremor andParkinsons. After all, the first step in getting care as early on as possible is self-awareness that you might be suffering from one of these conditions.
What Research Is Being Done
The mission of the National Institute of Neurological Disorders and Stroke is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. The NINDS is a component of the National Institutes of Health , the leading supporter of biomedical research in the world.
Researchers are working to better understand the underlying brain functions that cause tremor, identify the genetic factors that make individuals more susceptible to the disorder, and develop new and better treatment options.
Brain functioningIt can be difficult to distinguish between movement disorders such as Parkinsons disease and essential tremor. These debilitating movement disorders have different prognoses and can respond very differently to available therapies. NINDS researchers are working to identify structural and functional changes in the brain using non-invasive neuroimaging techniques to develop sensitive and specific markers for each of these diseases and then track how they change as each disease progresses.
Other researchers are using functional magnetic resonance imaging technology to better understand normal and diseased brain circuit functions and associated motor behaviors. Scientists hope to design therapies that can restore normal brain circuit function in diseases such as Parkinsons disease and tremor.

How Is Essential Tremor Treated And Managed
At present there is no cure for essential tremor, but tremors can be alleviated with multiple therapies. Mild tremors may not require pharmacological treatments and can be addressed with various non-pharmacological techniques. These techniques include the use of weighted utensils or application of weights to the wrists during daily functional tasks to reduce the amplitude of tremors. These weights are available at stores such as Walmart and Target, or can be ordered online. Another non-pharmacological approach is use of cooling the arms a technique also used for the control of tremors. All of these techniques can successfully control some of the tremors in although the benefits are short-lasting for some patients. At University of Florida, clinicians routinely schedule essential tremor patients with an occupational therapist for evaluation and demonstration of these techniques.
In conclusion, essential tremor is a slow progressive disease, has clear well-established guidelines for diagnosis and can be treated by nonpharmacological, pharmacological and surgical approaches.
What Causes The Condition
Although there are several recognized risk factors for Parkinsons disease, such as exposure to pesticides, for now, the only confirmed causes of Parkinsons disease are genetic. When Parkinsons disease isnt genetic, experts classify it as idiopathic . That means they dont know exactly why it happens.
Many conditions look like Parkinson’s disease but are instead parkinsonism from a specific cause like some psychiatric medications.
Familial Parkinsons disease
Parkinsons disease can have a familial cause, which means you can inherit it from one or both of your parents. However, this only makes up about 10% of all cases.
Experts have linked at least seven different genes to Parkinson’s disease. They’ve linked three of those to early-onset of the condition . Some genetic mutations also cause unique, distinguishing features.
Idiopathic Parkinsons disease
Experts believe idiopathic Parkinsons disease happens because of problems with how your body uses a protein called -synuclein . Proteins are chemical molecules that have a very specific shape. When some proteins dont have the correct shape a problem known as protein misfolding your body cant use them and can’t break them down.
With nowhere to go, the proteins build up in various places or in certain cells . The buildup of these Lewy bodies causes toxic effects and cell damage.
The possible causes are:

How Is Essential Tremor Diagnosed
The appearance of your tremor, in the setting of a comprehensive neurological examination by an experienced clinician, can result in diagnosis of essential tremor. Your doctor will probably need to rule out other conditions that could cause shaking or trembling. For example, tremors could be symptoms of diseases such as hyperthyroidism. Your health care provider might test you for those as well.
In some cases, the tremors might be related to other factors. To find out for certain, your health care provider may have you try to:
- Abstain from heavy alcohol use trembling is a common symptom among people with alcohol use disorder.
- Avoid caffeine.
- Avoid or reduce certain medicines.
How Is Essential Tremor Evaluated
Essential tremor most commonly affects the arms, tremors are typically asymmetric in the beginning and with advancement, tremors of other regions, notably the head, face, voice, trunk, and legs, are seen either separately, or in combination. There is also a general rule, if prominent tremors are seen in the legs, Parkinsons disease should be ruled out.
Diagnosis of essential tremor is based on specific criteria observed during the clinical exam. These criteria include the presence of tremors in both hands and forearms engaged in routine daily tasks and absence of any additional neurologic symptoms or signs. A bedside physical exam involves observation of tremors during postural elevation of the arms, on kinetic tasks like drawing an Archimedes spiral , line drawing, writing, pouring water into glass and on intentional maneuver such as finger-to nose testing. Tremors occur mainly in the distal hands and are 4 to 12 Hz in frequency, but this can be widely variable. Tests such as those shown below are ways in which a physician can evaluate and monitor tremor.

Clinical Trials For Parkinsons
A number of clinical trials investigating the cause of Parkinsons, how the disease progresses, and new medications are also underway.
One ongoing study involves the use of a molecular medication that can cross the blood-brain barrier to target early Parkinsons to stop the progression of the disease to later stages.
No home remedies can cure or reverse Parkinsons disease development or progress.
The following home remedies are being studied as possible promising therapies for Parkinsons disease:
- H2 water. H2 water is water with added hydrogen gas. Its being examined in experimental trials as a potential way to
Medications For Essential Tremor
Propanolol and primidone are two of the medicines often prescribed to treat essential tremor.
Propanolol blocks the stimulating action of neurotransmitters to calm your trembling. This beta blocker is effective in 40% to 50% of patients and is less useful in reducing head and voice tremor. It is usually avoided in patients with asthma, emphysema, congestive heart failure or heart block, and should be used with caution by people with diabetes who are on insulin. These drugs may reduce exercise tolerance, lower blood pressure or heart rate, exacerbate depression and cause impotence. Other adrenergic blockers with fewer side effects include atenolol, nadolol, metoprolol and timolol.
Primidone controls the actions of neurotransmitters. Some patients starting primidone may experience a first dose phenomenon during which they have transient feelings of unsteadiness, dizziness and nausea during the beginning stages of treatment. This is usually short-lived. Sedation is another common side effect and can be reduced by following a slowly escalating dose schedule. Most patients are able to tolerate the side effects, and studies have shown that 60% to 100% of patients respond positively.
If primidone or propranolol are not effective by themselves, a combination of both may provide relief for some patients.

What Is The Difference Between Essential Tremor And Parkinsons Disease
When assessing the health of a person with a trembling disorder, medical professionals must look for certain key aspects that differentiate this condition from Parkinsons disease, as up to 30% of people with the latter initially receive a wrong diagnosis. The main differences between essential tremor and Parkinsons disease concern the following aspects:
- the timing of tremors: in people with essential tremor, trembling occurs when they use their hands, whereas in individuals with Parkinsons disease, trembling occurs when their hands are at their sides or resting in their lap
- related conditions: while essential tremor usually do not cause additional health problems, people with Parkinsons disease experience stooped posture, slow movement and shuffling gait
- the affected parts of the body: the hands, voice and head are typically the parts of the body affected by essential tremor, whereas the trembling associated with Parkinsons disease starts in the hands and subsequently affects the legs, chin and other parts of the body
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.
