Essential tremor

Common Name(s)

Essential tremor, Benign Essential Tremor Syndrome

Essential tremor is a disorder of the nervous system that causes involuntary, rhythmic shaking (tremor), especially in the hands. It involves tremor without any other signs or symptoms, and is distinguished from tremor that results from other disorders or known causes, such as tremors seen with Parkinson disease or head trauma.  Essential tremor (sometimes called benign essential tremor) is the most common of the more than 20 types of tremor. The causes of essential tremor are unknown. Several genes as well as environmental factors likely play a role in a person's risk of developing this complex condition.  In mild cases, treatment may not be necessary. In cases where symptoms interfere with daily living, medications may help to relieve symptoms.

Distinguishing the central drive to tremor in Parkinson's disease and essential tremor.
 

Author(s): John-Stuart Brittain, Hayriye Cagnan, Arpan R Mehta, Tabish A Saifee, Mark J Edwards, Peter Brown

Journal: J. Neurosci.. 2015 Jan;35(2):795-806.

 

Parkinson's disease (PD) and essential tremor (ET) are the two most common movement disorders. Both have been associated with similar patterns of network activation leading to the suggestion that they may result from similar network dysfunction, specifically involving the cerebellum. ...

Thalamomuscular coherence in essential tremor: hen or egg in the emergence of tremor?
 

Author(s): David J Pedrosa, Eva-Lotte Quatuor, Christiane Reck, K Amande M Pauls, Carlo A Huber, Veerle Visser-Vandewalle, Lars Timmermann

Journal: J. Neurosci.. 2014 Oct;34(43):14475-83.

 

Thalamomuscular coherence in essential tremor (ET) has consistently been detected in numerous neurophysiological studies. Thereby, spatial properties of coherence indicate a differentiated, somatotopic organization; so far, however, little attention has been paid to temporal aspects ...

The nature of tremor circuits in parkinsonian and essential tremor.
 

Author(s): Hayriye Cagnan, Simon Little, Thomas Foltynie, Patricia Limousin, Ludvic Zrinzo, Marwan Hariz, Binith Cheeran, James Fitzgerald, Alexander L Green, Tipu Aziz, Peter Brown

Journal: Brain. 2014 Dec;137(Pt 12):3223-34.

 

Tremor is a cardinal feature of Parkinson's disease and essential tremor, the two most common movement disorders. Yet, the mechanisms underlying tremor generation remain largely unknown. We hypothesized that driving deep brain stimulation electrodes at a frequency closely matching ...

What is essential tremor?
 

Author(s): Rodger J Elble

Journal: Curr Neurol Neurosci Rep. 2013 Jun;13(6):353.

 

Classic essential tremor is a clinical syndrome of action tremor in the upper limbs (at least 95 % of patients) and less commonly the head, face/jaw, voice, tongue, trunk, and lower limbs, in the absence of other neurologic signs. However, the longstanding notion that essential tremor ...

Essential tremor followed by progressive supranuclear palsy: postmortem reports of 11 patients.
 

Author(s): Elan D Louis, Rachel Babij, Karen Ma, Etty Cort├ęs, Jean-Paul G Vonsattel

Journal: J. Neuropathol. Exp. Neurol.. 2013 Jan;72(1):8-17.

 

For many years, clinicians have commented on the development of signs of parkinsonism among their essential tremor (ET) patients, but the links between ET and parkinsonism are not well understood. We report 11 (12.4%) of 89 ET patients who were prospectively collected at the Essential ...
