Essential tremor – Pathogenesis and diagnostic overview

Abstract

Although essential tremor (ET) is a common movement disorder, the neural mechanism underlying this condition remains unknown. Because no diagnostic pathologic findings or biologic markers are available, correct diagnosis often depends on the clinician’s skill in recognizing the clinical features of ET. This article tries to provide an overview of the current concepts in pathophysiology and diagnosis of ET.
