Intention tremor in essential tremor : prevalence and association with disease duration

Louis, Elan D.; Frucht, Steven; Rios, Eileen

Scholarly attention only recently has been focused on intention tremor (IT) in essential tremor (ET).1, 2 Therefore, little has been written on its prevalence or clinical correlates. The association between IT and disease duration also remains unsettled. This question has pathophysiological implications. Studies have indicated metabolic and structural changes in the ET cerebellum.3, 4 If ET were a disease of progressive cerebellar dysregulation, one would expect more IT in patients with disease of longer duration. We assessed the prevalence and clinical correlates of IT and determined whether there was an association between IT and disease duration.
