RT Journal Article SR Electronic T1 Essential tremor: a nuanced approach to the clinical features JF Practical Neurology JO Pract Neurol FD BMJ Publishing Group Ltd SP 389 OP 398 DO 10.1136/practneurol-2018-002183 VO 19 IS 5 A1 Elan D Louis YR 2019 UL http://pn.bmj.com/content/19/5/389.abstract AB Essential tremor is the most common form of tremor in humans. Given neurologists’ high exposure to this condition, and its seemingly straightforward phenotype, it might seem easy to diagnose. However, 30%–50 % of patients labelled as having ‘essential tremor’ have other diagnoses, mostly Parkinson’s disease and dystonia. The tremor of essential tremor is neither non-descript nor featureless but is multifaceted and highly patterned. This review focuses on its clinical features, beginning with a discussion of tremors and then briefly discussing its additional motor features, and presents several aids to help distinguish essential tremor from Parkinson’s disease and dystonia. Careful attention to certain clinical nuances will aid the diagnosis and care of patients with essential tremor.
