Resumo<i>Objectives:</i> To assess the prevalence of essential tremor (ET) in two Spanish populations (Irun and Hondarribia, Bidasoa region) and to compare the results with those of similar surveys. <i>Methods:</i> The survey included 2,000 participants aged 65 years or older in a door-to-door, two-phase design. ET was defined as postural or kinetic tremor of the head or limbs. <i>Results:</i> ET prevalence after age adjustment was 4.8% (95% confidence interval, 3.6–6.4). Prevalence increased significantly with age and there were no sex differences. <i>Conclusions:</i> The age-adjusted prevalence rate of ET in people 65 years old and older in Bidasoa, Spain, is close to those described in other studies using a similar design and suggest no geographical variation. ET prevalence increases with age and has a similar distribution in males and females.
