How Common is Essential Tremor? Update on the Worldwide Prevalence of Essential Tremor

Essential tremor (ET) is among the most prevalent movement disorders. Comprehensive reviews of disease prevalence were published in 1998 and 2010 but not since then. This paper reviews the prevalence of ET in population-based epidemiological studies, derives a precise summary estimate of prevalence from these studies, and examines differences in prevalence across studies.
