متن کاملElectrophysiologic transition from physiologic tremor to essential tremor.
We electrophysiologically examined the transition from physiologic tremor to essential tremor in people at risk for familial essential tremor. Two healthy people from different families with hereditary essential tremor were studied on multiple occasions. A 23-year-old man was studied in 1995, 1997, and 2004, and a 44-year-old woman was studied in 1993, 1995, 1997, and 2003. Hand acceleration an...

PHENOMENOLOGY SHOWN A PD patient with a re-emergent tremor occurring during a task (spiral drawing), which on the surface produced a tremor that resembled that of essential tremor (ET).

متن کاملTremor in a Bassoonist: Tremor in Dystonia or Essential Tremor?
JMD Dear Editor, Tremor is a common clinical feature in dystonia. It can be seen in both affected and unaffected body parts in patients with dystonia. Clinically, it may not be easily distinguishable from essential tremor, currently defined as a bilateral, largely symmetric postural or kinetic tremor involving the hands and forearms that is visible and persistent, with an associated or isolated...
متن کاملEssential Tremor: A Neurodegenerative Disease?
BACKGROUND Essential tremor (ET) is one of the most common neurological disorders among adults, and is the most common of the many tremor disorders. It has classically been viewed as a benign monosymptomatic condition, yet over the past decade, a growing body of evidence indicates that ET is a progressive condition that is clinically heterogeneous, as it may be associated with a spectrum of cli...
