Essential Tremor

Essential Tremor

Essential Tremor (ET) is a neurological problem characterized by involuntary rhythmic shaking of particular body parts, typically the hands, arms, head, and voice. While it is often confused with Parkinson’s disease, essential tremor is a distinct condition that affects millions of people worldwide. This article explains the signs and symptoms, causes and risk factors, diagnosis, and available preventive measures and treatment plans for essential tremors.

Signs and Symptoms

Essential tremor primarily manifests as rhythmic and intentional tremors during voluntary movements. Unlike Parkinson’s disease, essential tremor is generally not associated with resting tremors. Earthquakes can vary from mild to severe and may worsen with age. Common signs and symptoms include:

  • Tremors: The hallmark symptom of essential tremor is involuntary shaking, commonly affecting the hands, but it can extend to other body parts such as the head, arms, and voice.

  • Worsening with Movement: Essential tremors become more pronounced during voluntary movements like reaching for an object or holding a cup.

  • Intensity Variability: Tremors can vary throughout the day, often worsening during stress, fatigue, or strong emotions.

  • Head Nodding or Shaking: In some cases, essential tremor may cause a nodding or shaking of the head.

  • Voice Tremor: Individuals with essential tremors may experience tremors in their voice, impacting speech clarity.

Causes and Risk Factors

The exact cause of essential tremor remains unclear, but a mixture of environmental and genetic factors is believed to contribute to its development. Key factors include:

  • Genetics: There is a vital familial component to essential tremor, with many cases having a family history. Specific genetic mutations have been linked with an increased risk.

  • Neurological Abnormalities: Essential tremor is linked to abnormalities in the cerebellum, the part of the brain that controls coordination and movement.

  • Environmental Factors: Certain environmental factors, such as toxins or trauma, may contribute to developing or worsening essential tremors.


Diagnosing essential tremors involves:

  • A thorough medical history.

  • Physical examination.

  • Sometimes, additional tests are needed to rule out other possible causes of earthquakes.

Critical diagnostic steps include:

  1. Clinical Assessment: A healthcare professional will evaluate the nature and pattern of tremors, considering the patient’s medical and family history.

  2. Neurological Examination: A comprehensive neurological examination assesses muscle strength, coordination, and reflexes.

  3. Blood Tests and Imaging: Blood tests and imaging studies, such as MRI or CT scans, may be performed to rule out other medical conditions that could be causing the tremors.

  4. Genetic Testing: In cases with a strong family history of essential tremor, genetic testing may be recommended to identify specific genetic mutations.

Preventive Measures and Treatment Plans

While essential tremor is a chronic condition without a cure, several preventive measures and treatment options can help improve affected individuals’ symptoms and the quality of life.

Lifestyle Modifications:

Stress Management: Stress can exacerbate tremors, so stress-reduction techniques such as meditation, yoga, and deep breathing exercises may be beneficial.

Adequate Sleep: Ensuring sufficient and quality sleep can help alleviate tremors.


Beta-Blockers: Medications like propranolol and primidone are commonly prescribed to reduce tremor severity.

Anti-Seizure Medications: Drugs such as gabapentin or topiramate may sometimes be effective.

Physical Therapy:

Physical therapists can provide exercises and strategies to improve brain-body coordination and reduce the impact of tremors on daily activities.

Deep Brain Stimulation (DBS):

DBS may be recommended in severe cases where medications are ineffective. It involves the implantation of electrodes in the brain to regulate abnormal nerve signals.

Speech Therapy:

Speech therapy can improve speech clarity and communication skills for individuals with voice tremors.


In conclusion, essential tremor is a neurological disorder that can tremendously impact an individual’s daily life. While there is no cure, a combination of lifestyle modifications, medications, and therapies can help manage symptoms effectively. Early diagnosis and a comprehensive treatment plan tailored to the individual’s needs are crucial in enhancing the quality of life for those with essential tremors. If you or someone you know is experiencing tremors or related symptoms, seeking medical advice for proper evaluation and guidance is necessary.
