Essential tremor (ET) is one of the most common movement disorders in the world, with prevalence rates in the general population ranging from 0.4% to 4.6%.1,2 The incidence of ET increases with age,1 with the average age at onset in mid-to-late 40s.3 ET is estimated to affect as many as 7 to 10 million Americans.3,4 Clinically, ET is characterized by bilateral, symmetric, postural tremor in hands and forearms, with or without kinetic tremor, in the absence of abnormal posturing or task specificity.5 ET can also affect lower extremities, head, and voice.6,7 Symptoms may be barely noticeable, or severe and disabling.
