Symptoms of ET
  • Uncontrollable shaking in your hands that occurs over time 
  • Shaking voice
  • Tremoring Legs
  • Entire body tremors
  • Nodding or shaking the head   
​ Head tremor may be seen as a "yes-yes" or "no-no" motion.
  • Tremors that worsen during periods of emotional stress
​Heightened emotion, stress, fever, physical exhaustion, or hypoglycemia may trigger tremors or increase their severity.
  • Tremors that get worse with purposeful movement 
​ Hand tremors may interfere with purposeful activities like eating, writing, sewing, or shaving.
  • Tremors that lessen with rest
  • Balance problems 
​ET may be accompanied by mild gait disturbance. There may be mild degeneration in certain parts of the cerebellum in persons with Essential Tremor.  ​
  • Not able to write your name
  • ​Essential Tremor can be Inherited 
​​Children of a parent who has Essential Tremor have up to a 50 percent chance of inheriting the condition. ​
What is tremor?
A tremor is a repetitive movement of a part of the body. It is involuntary. This means that it is generally uncontrollable and occurs without your decision to move that body part. It is often felt as a trembling or shaking sensation.

Action tremor:
A voluntary movement, such as lifting a cup to one's mouth.
Postural tremor: A voluntary holding of a position against gravity, such as reaching or extending one's hand or arm. Most people with ET experience both postural and action tremor.

What causes Essential Tremor?
Essential tremor is a familial condition, meaning it runs in families. At least 5-7 out of 10 people with essential tremor have other members of the family with the same condition. Genes are inherited from each parent and determine what we look like, how our bodies function, and even what diseases we get. Certain genes have been shown to exhibit specific mutations in families with Essential Tremor. 

How is Essential Tremor diagnosed?
​There is no diagnostic test for Essential Tremor. Your doctor can usually diagnose essential tremor based on your explanation of the tremor and an examination. It is important for the doctor to ensure that no other conditions are causing the tremor. 

What is the treatment for Essential Tremor?
Essential Tremor cannot be cured. Treatment reduces the severity of the tremor, sometimes greatly. Various treatments are used.

Medication
There are two medicines used initially for Essential Tremor - propranolol and primidone. These medicines have been shown to reduce tremor in up to 8 in 10 affected individuals.

Surgery
If medical treatment is ineffective and the tremor is severe, surgical intervention may be an option. There are two main surgical procedures that may be considered: thalamic deep-brain stimulation & Focus Ultrasound. They both involve the thalamus. This is a deep part of the brain that organizes messages traveling between the body and brain.

What is the outlook?
Essential tremor is called a progressive disease. This indicates that it tends to worsen over time.  
There is no definitive cure for Essential Tremor.
Despite its prevalence, it wasn't until 2013 that Essential Tremor was given its own specific diagnostic code, one that's distinct from other tremors, in the 10th edition of the World Health Organization's International Statistical Classification of Disease and Related Health Problems (ICD) code book. ICD-10-CM Code for Essential Tremor G25.0
ICD-10 code G25.0 for Essential Tremor is a medical classification as listed by WHO under the range - Diseases of the nervous system.  
​​
The ICD-10-CM code for essential tremor is G25.0. The ICD is the International Classification of Diseases, a system used by the World Health Organization (WHO) to classify health disorders. 

The ICD-10-CM code for essential tremor 
  • The ICD-10-CM code G25.0 was the first specific diagnostic code for essential tremor.
  • Essential tremor is a common neurological disease that causes kinetic tremors in the arms.
  • Other features of essential tremor include postural, rest, and intentional tremors, as well as motor and non-motor features.

​ Actress Katharine Hepburn. Presidents John Adams and John Quincy Adams. Playwright Eugene O’Neill. U.S. Senator Robert Byrd. All of them suffered from Essential Tremor, which affects an estimated 10 million Americans.  

There aren't any blood or other medical tests that can definitively diagnose Essential Tremor. Instead, a neurologist makes the diagnosis based on a detailed medical history and a neurological evaluation designed in part to rule out other possible causes of the tremor. 

Essential Tremor can interfere with one's life, and you can't work or do daily activities. If it impairs your ability to function, the condition is usually treated with medications such as beta-blockers, anti-seizure drugs, anti-anxiety meds or Botox injections. There's considerable trial and error in finding a medication that works well for a given patient; sometimes drug treatment helps sufficiently, and sometimes it doesn't.

For people with severe tremors that don't respond to drugs, surgical therapies, and other treatments are gaining traction. With deep brain stimulation, a probe is implanted in the thalamus, the brain region that causes tremors, and a wire runs from the probe to a pacemaker-like device implanted in the chest.

There is also Focused Ultrasound, a noninvasive, MRI-guided, high-intensity ultrasound technique that uses focused ultrasound waves to selectively damage the brain regions that contribute to tremors.
​What Affective and Behavioral Symptoms Are Associated with Movement Disorders?
Depression and anxiety occur with high frequency in patients with movement disorders. At the same time, depression is severely underrecognized by clinicians who treat patients with movement disorders, quite possibly owing to the significant clinical overlap between these conditions.
