Neurol."],"abstract":"<jats:p>Tremor is the most commonly encountered movement disorder in clinical practice. A wide range of pathologies may manifest with tremor either as a presenting or predominant symptom. Considering the marked etiological and phenomenological heterogeneity, it would be desirable to develop a classification of tremors that reflects their underlying pathophysiology. The tremor task force of the International Parkinson Disease and Movement Disorders Society has worked toward this goal and proposed a new classification system. This system has remained a prime topic of scientific communications on tremor in recent times. The new classification is based on two axes: 1. based on the clinical features, history, and tremor characteristics and 2. based on the etiology of tremor. In this article, we discuss the key aspects of the new classification, review various tremor syndromes, highlight some of the controversies in the field of tremor, and share the potential future perspectives.<\/jats:p>","DOI":"10.3389\/fneur.2021.684835","type":"journal-article","created":{"date-parts":[[2021,7,26]],"date-time":"2021-07-26T05:31:49Z","timestamp":1627277509000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":125,"title":["Tremor Syndromes: An Updated Review"],"prefix":"10.3389","volume":"12","author":[{"given":"Abhishek","family":"Lenka","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Jankovic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,7,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"75","DOI":"10.1002\/mds.27121","article-title":"Consensus Statement on the classification of tremors from the task force on tremor of the International Parkinson and Movement Disorder Society","volume":"33","author":"Bhatia","year":"2018","journal-title":"Mov Disord."},{"key":"B2","doi-asserted-by":"publisher","first-page":"959","DOI":"10.1212\/CON.0000000000000748","article-title":"Tremor","volume":"25","author":"Louis","year":"2019","journal-title":"Contin Lifelong Learn Neurol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"692","DOI":"10.1136\/jnnp-2017-317057","article-title":"Leg stereotypy syndrome: phenomenology and prevalence","volume":"89","author":"Lotia","year":"2018","journal-title":"J Neurol Neurosurg Psychiatry."},{"key":"B4","doi-asserted-by":"publisher","first-page":"640","DOI":"10.1002\/mds.25355","article-title":"Prevalence and clinical classification of tremor in elderly-A community-based survey in Brazil","volume":"28","author":"Barbosa","year":"2013","journal-title":"Mov Disord."},{"key":"B5","doi-asserted-by":"publisher","first-page":"534","DOI":"10.1002\/mds.22838","article-title":"How common is the most common adult movement disorder?
