RESUMEN
INTRODUCTION: Essential tremor (ET) is one of the most common movement disorders; however, many patients are misdiagnosed and do not receive effective treatment. It is important to better understand the diagnosis, symptoms and treatment patterns to improve care for those with ET. METHODS: Persons in the International Essential Tremor Foundation database were invited to complete an online survey, focusing on symptoms, diagnosis, and treatment of ET. RESULTS: The survey was emailed to 19,206 persons, with 2864 (14.9%) respondents. Mean age was 65.4 years, median age of tremor onset was 36-40 years, 61% were women, and 64% had a known family history of tremor. Forty-five percent saw multiple physicians before a diagnosis of ET with 65% being diagnosed by a neurologist. Current care is provided by a neurologist in 42%, a family physician in 26% and 28% do not see a physician for ET. Tremor was most commonly reported in the hands/arms (95%). The most commonly affected daily activities included writing, eating, drinking and carrying. Beta-blockers were the most commonly used treatment (42%); however, 33% had no benefit and 35% discontinued due to side effects. Of note, 33% had never received treatment for their tremor. CONCLUSION: This survey highlights the need for more effective treatments with greater tolerability. Increased awareness among physicians and patients in the diagnosis and treatment of ET is also warranted, with nearly half the respondents seeing multiple physicians before receiving an ET diagnosis and nearly 30% not seeing a physician and/or not receiving treatment for ET.
