Abstract

Patients with essential tremor (ET) have kinetic arm tremor; this tremor can also have an intentional component. We are unaware of reports of intention tremor of the head in ET. Our aims were to describe, provide electrophysiological data and video documentation of, and estimate the prevalence of intention tremor of the head in our sample. Ten (9.0%; 95% confidence interval = 4.7%–14.3%) of 111 patients had intention tremor of the head; in 7 it involved the neck and in 3 the chin. These patients trended toward having more severe kinetic arm tremor and they had more severe intention tremor of the arms. These observations provide further support for the evolving view that the cerebellum may be involved in ET. Β© 2006 Movement Disorder Society

In both, the deficit occurs early in the disease. Isolated rest tremor without other signs of parkinsonism can occur in patients with ET. I

## Abstract Mirror movements (MM), which occur in age‐related neurodegenerative diseases such as Parkinson's disease (PD), have never been studied in essential tremor (ET). The objective of this work is to study the prevalence and clinical correlates of MM in ET cases and controls. In a clinical‐ep
