Essential Tremor: Causes and Treatments

Essential tremor is a neurological disorder that causes involuntary and rhythmic shaking. It's the most common movement disorder, affecting millions of people worldwide.

Essential tremor (ET) is a progressive neurological condition characterized by uncontrollable shaking or tremors in different parts of the body. The most commonly affected areas are the hands, head, voice, and legs. Unlike Parkinson's disease, which is another well-known tremor disorder, essential tremor doesn't lead to other health problems.

While it can occur at any age, essential tremor is more common in people aged 40 and older. The severity of the tremors can vary from mild and barely noticeable to severe and debilitating.

Causes of Essential Tremor

Genetic Factors

Essential tremor is often hereditary. Studies indicate that about half of the people with essential tremor have a family member who also has the condition. This suggests a strong genetic component. If one of your parents has essential tremor, you have a 50% chance of developing it as well.

Environmental Factors

Although the exact cause of essential tremor is not fully understood, researchers believe that environmental factors could also play a role. These might include exposure to certain toxins or chemicals, though more research is needed to confirm these links.


Symptoms of Essential Tremor

The primary symptom of essential tremor is shaking that occurs during voluntary movements, such as eating, writing, or holding objects. Here are the most common symptoms:

  • Tremors in the hands, arms, head, or voice
  • Shaking that worsens with movement
  • Tremors that get worse with stress, fatigue, or caffeine
  • Balance problems in severe cases

The symptoms can be mild at first and may progress over time. They often worsen with age.


Diagnosis of Essential Tremor

Diagnosing essential tremor involves a thorough medical history and a physical exam. Here are the steps doctors typically follow:

Medical History

Doctors will ask about your symptoms, their frequency, and whether you have a family history of tremors. They may also inquire about medications you're taking and any other medical conditions you have.

Physical Examination

During the physical exam, your doctor will observe the tremors and check for other signs that might indicate a different condition, like Parkinson's disease.

Neurological Tests

Neurological tests may include assessments of your reflexes, muscle strength, and coordination. These tests help rule out other conditions that can cause tremors.

Imaging Tests

In some cases, doctors may recommend imaging tests like MRI or CT scans to rule out other potential causes of the tremors, such as a stroke or brain tumor.


Treatment Options for Essential Tremor

Medications

Medication is often the first line of treatment for essential tremor. Some of the most commonly prescribed medications include:

  • Beta-blockers: Drugs like propranolol can help reduce tremors.
  • Anti-seizure medications: Medications such as primidone are often effective.
  • Tranquilizers: In cases where anxiety worsens tremors, tranquilizers like diazepam may be prescribed.

Supportive Therapy

Supportive therapies can also be beneficial. These include:

  • Physical therapy: Exercises to improve muscle control and coordination.
  • Occupational therapy: Techniques to help manage daily activities more easily.
  • Speech therapy: If your voice is affected, speech therapy can help improve your communication skills.

Lifestyle Changes

Certain lifestyle changes can help manage the symptoms of essential tremor:

  • Avoid caffeine: Caffeine can worsen tremors.
  • Reduce stress: Stress management techniques like meditation and yoga can be helpful.
  • Limit alcohol: While small amounts of alcohol can temporarily reduce tremors, relying on alcohol is not advisable.

Surgical Treatments

For severe cases that don't respond to medication or therapy, surgical options are available:

  • Deep Brain Stimulation (DBS): A device is implanted in the brain to send electrical signals that help control tremors.
  • Focused Ultrasound: This non-invasive procedure uses ultrasound waves to target and destroy the brain tissue causing the tremors.

Natural Remedies for Essential Tremor

Many people look for natural ways to manage their essential tremor. While there's no cure, some natural remedies may help alleviate symptoms:

  • Herbal supplements: Some people find relief with herbal supplements like valerian root or passionflower.
  • Mind-body techniques: Practices like Tai Chi and Qigong can improve balance and reduce stress.
  • Dietary changes: A diet rich in antioxidants and omega-3 fatty acids may support overall brain health.

Personal Stories: How I Cured My Essential Tremor Naturally
