Area of Science:

  • Neurology
  • Movement Disorders

Background:

  • Essential tremor (ET) is a prevalent neurological condition with a frequency of 4 to 12 Hz.
  • It is characterized by its absence at rest and accentuation during postural maintenance and movement termination.
  • The exact origin (central or peripheral) of ET remains a subject of debate.

Purpose of the Study:

  • To provide a comprehensive overview of essential tremor.
  • To discuss diagnostic criteria and current treatment options.

Main Methods:

  • Clinical diagnosis based on patient presentation and medical history.
  • Review of historical and current literature on essential tremor.

Main Results:

  • Essential tremor affects 300 to 415 per 100,000 Americans and can be disabling.

  • No specific diagnostic test exists for ET.
  • Ethanol is the most effective short-term suppressor of ET symptoms.

    • Conclusions:

    • Essential tremor is diagnosed clinically, with various historical terms used to describe it.
    • Current treatments include beta-adrenergic blockers, primidone, and benzodiazepines.
    • Further research is needed to clarify the etiology of essential tremor.
