Area of Science:

  • Neurology
  • Movement Disorders

Background:

  • Essential tremor is a prevalent neurological condition affecting millions in the US.
  • It is characterized by action and postural tremors, often impacting the arms and potentially causing significant disability.

Purpose of the Study:

  • To review the current understanding and treatment landscape of essential tremor.
  • To highlight the efficacy of various pharmacologic and surgical interventions.

Main Methods:

  • Review of existing literature on essential tremor.
  • Summary of first-line and alternative pharmacologic treatments.
