Essential tremor and buccolinguofacial dyskinesias

Acta Neurol Scand. 1982 Dec;66(6):705-8. doi: 10.1111/j.1600-0404.1982.tb04536.x.

Abstract

Essential tremor (ET) has been described in association with major dyskinesias, such as dystonia musculorum deformans, torticollis, and dystonic writer's cramp. In a series of 104 patients affected by ET, the incidence of buccolinguofacial dyskinesias (BLFD) has been investigated, including a comparison with another dyskinesia involving the facial muscles--mimic muscle tremor. The association of ET and BLFD may be casual; however, on the other hand, it might suggest the existence of a subgroup of patients suffering from a non-specific sign of motor control impairment, such as ET, in which other non-specific disorders of voluntary movement, such as BLFD, can gradually develop, particularly late in life.
