Essential tremor is both a paradoxical and an elusive disorder. It is paradoxical because, while it is one of the most common neurologic disorders affecting people of all ages in all human populations,1 it was not fully described until the end of the 19th century,2 and the term itself was not consistently used by neurologists until the second half of the 20th century.3- 6 It is elusive because there is no known diagnostic marker or consistently abnormal finding.
