Facial tremor in dystonia

Parkinsonism Relat Disord. 2014 Aug;20(8):924-5. doi: 10.1016/j.parkreldis.2014.04.029. Epub 2014 May 21.


Background: Tremor of the upper/middle part of the face, including the perinasal region and the forehead has been very rarely described in some patients with Parkinson's disease or Essential Tremor. It has not yet been reported in patients with idiopathic dystonia.

Methods: We describe here a series of 8 patients with common forms of idiopathic focal/segmental dystonia with tremor involving the upper/middle part of the face, along with demonstrative videos and electrophysiological recordings.

Results: The distribution of the tremor was confined to the face in two patients, whereas in six patients tremor was also evident either in the head/lower part of the face or in their upper limbs. Electrophysiological recordings disclosed a slightly irregular tremor with a frequency at about 3-5 Hz.

Conclusions: A number of patients with classical forms of dystonia can show a tremor involving the upper/middle part of the face.

Keywords: Dystonia; Dystonic tremor; Facial tremor; Jaw tremor; Tremor of the face.
