Description

Characteristics of Essential Tremor

Essential tremor (ET) is a neurological disorder that causes involuntary and rhythmic shaking or trembling of various parts of the body, including:

  • Rhythmic shaking in the hands, arms, head, legs, or torso
  • Shaky voice
  • Difficulty writing or drawing
  • Problems holding and controlling utensils

These symptoms can vary from person to person and may worsen over time. ET is often confused with Parkinson's disease, but it is a distinct condition that affects millions of people worldwide.

Key Points:

  • Essential tremor is the most common movement disorder.
  • It causes involuntary shaking or trembling of various body parts.
  • Symptoms can include shaky voice, difficulty writing, and problems holding utensils.
  • ET is not life-threatening and can usually be kept under control with treatment.

Signs and Symptoms

Common Signs and Symptoms of Essential Tremor

Essential tremor is characterized by involuntary shaking or trembling of certain parts of the body, usually the head and hands. The symptoms can vary from person to person, but here are some common signs and symptoms:

  • Rhythmic tremor: A rhythmic tremor in the hands, arms, head, or voice is a hallmark symptom of essential tremor.
  • Tremor occurs when movement starts: The tremor often begins when movement starts, which can continue or worsen during movement.
  • Shaking or trembling: Essential tremor causes involuntary shaking or trembling of particular parts of the body.

According to [6], other symptoms may include:

  • A rhythmic tremor in the hands, arms, head, or voice (it can also be felt as an “internal tremor”)
  • Tremor occurs when movement starts

These symptoms can affect different parts of the body and can vary in severity. If you're experiencing any of these symptoms, it's essential to consult a healthcare professional for proper diagnosis and treatment.

Diagnostic Tests

Diagnostic Tests for Essential Tremor

Essential tremor can be diagnosed through a combination of medical history, physical examination, and various tests. Here are some diagnostic tests used to evaluate essential tremor:

  • Medical History: A thorough review of your medical history, family history, and symptoms is crucial in diagnosing essential tremor.
  • Physical Examination: A neurologist specializing in movement disorders will perform a physical examination to assess the severity and characteristics of the tremors.
  • Imaging Tests: While imaging tests such as MRI and CT scans are not helpful in diagnosing essential tremor, they may be performed to rule out other possible conditions. [6][8]
  • Spiral Test: One diagnostic tool used to test and diagnose a tremor is a drawing task known as a spiral test or an Archimedes spiral test. This test involves drawing a spiral, which can help assess the severity of the tremors. [4][7]

Other Tests

In addition to these tests, other evaluations may be performed to rule out other conditions that may be causing symptoms. These include:

  • Blood and Urine Tests: To check for signs of infections, genetic disorders, or other conditions.
  • Dopamine Imaging: To assess dopamine levels in the brain.

It's essential to consult a neurologist specializing in movement disorders for an accurate diagnosis and treatment plan.

Additional Diagnostic Tests

  • Imaging Tests
  • Physical Examination
  • Medical History
  • Blood and Urine Tests
  • Spiral Test
  • Dopamine Imaging

Treatment

Medications Used to Treat Essential Tremor

Essential tremor can be effectively managed with various medications, which are often used in combination with other treatments such as assistive devices and lifestyle modifications.

  • Beta-Blockers: Beta-blockers, specifically propranolol (Hemangeol, Inderal LA, Inderal XL, InnoPran XL), are commonly prescribed to treat essential tremor. These medications work by blocking the effects of adrenaline on the body, which can help reduce tremors.
  • Anti-Seizure Medications: Anti-seizure medications like primidone are also used to manage essential tremor. These medications have been shown to be effective in reducing tremors and improving quality of life.

It's worth noting that while these medications can be effective, they may not work for everyone, and the effectiveness of each medication can vary from person to person [6].

Recommended Medications

  • Beta-Blockers
  • Anti-Seizure Medications

Differential Diagnosis

Essential Tremor Differential Diagnosis

The differential diagnosis of essential tremor (ET) involves considering various conditions that may present with similar symptoms, such as tremors, to rule out other potential causes.

Conditions to Consider:

  • Cerebellar tremor: This type of tremor is often associated with cerebellar dysfunction and can be a consideration in the differential diagnosis of ET.
  • Parkinsonian tremor: A tremor that occurs in patients with Parkinson's disease or other parkinsonian syndromes, which can mimic ET symptoms.
  • Physiological tremor: An exaggerated physiological tremor can sometimes be mistaken for ET, especially if it is unilateral (occurring on one side of the body).
  • Psychogenic tremor: This type of tremor is caused by psychological factors and can be a consideration in the differential diagnosis of ET.

Other Conditions:

  • Multiple system atrophy
  • Progressive supranuclear palsy
  • Cortical basal degeneration
  • Toxin-induced tremor
  • Postencephalitic parkinsonism

It's essential to note that a thorough medical history, physical examination, and diagnostic tests are necessary to accurately diagnose ET and rule out other potential causes.
