β¦ Synopsis
Essential tremor (ET) is one of the most common movement disorders. However, the etiology and pathogenesis are as yet unknown. Continued research will give us clues to understanding the impact on society, identifying genetic and environmental contributors to the disease, understanding the significance of a sporadic case, the phenotypic spectrum and timing of presentation, and the relationship with other neurologic disorders. Because the condition is both clinically and genetically heterogeneous and there is overlap with these other disorders, such as dystonia, parkinsonism, peripheral neuropathy, and migraine, the definition of phenotype plagues research in this area. Advances in understanding the genetic and molecular underpinnings of tremor should provide additional tools to unravel the clinical phenotype (including physiology), genotype-phenotype relationships, and the epidemiology of tremor.

## Abstract In one crossβsectional study of a community in northern Manhattan, women with essential tremor (ET) were more likely to have head tremor than were men. In that study, patients were seen at one point in time, rather than followed longitudinally. Head tremor often develops after arm tremo
Twenty patients with tongue tremor associated with essential tremor are reported. Patients were unaware of the tongue tremor, and voice disturbance was a complaint in only one patient. Three patients had an isolated tongue tremor. Hand tremor was present in 16 patients. Dystonia, myoclonus, 4 m 25lM
